CB vs CVB – what is the difference between the tasks and roles of European and North American convention bureaux?

Purpose – The purpose of this paper is to analyse the divergence between the tasks and roles of convention bureaux (CB) in North America and Europe. Design/methodology/approach – A survey among 55 CB’ managers was conducted. A total of 75% of respondents represented institutions operating in European cities, 25% – in North American ones. This research mainly focused on managers’ opinions about the importance of tasks and roles performed by CB and the degree to which the institutions manage to fulfil them. Therefore, importance-performance analysis was used in the study. Findings – CB in North America and Europe broadly differ as to the characteristics of both groups of institutions. They include their time of operation, number of employees, annual budget and types of events that CB try to attract to the cities that they represent. There are no such differences when it comes to the importance and performance of institutions’ tasks and roles. The way in which managers evaluate them is quite similar because the respondents pay the closest attention to the roles of a marketer and an agent of a city played by a convention bureau. Differences lie in the meaning assigned by managers to the particular tasks of surveyed institutions. Originality/value – The survey was carried out on a relatively small sample dominated by European institutions. However, the study attempts at investigating the roles and tasks of CB, with only few previous studies on this topic, including the ones comparing CB’ activity in different countries or on different continents. Moreover, proposed recommendationsmight be useful for a large group of managers and do not have to be limited only to institutions fromEurope andNorth America.


Introduction
Business tourism is an important topic in scientific literature; however, not enough attention is paid to convention bureaux (CB). The Scopus database has almost 40 scientific papers on CB [1]. Most of them deal with a particular activity of these institutions like online marketing, especially the performance of CB' websites (Cobos et al., 2009;Davidson and Keup, 2014;Feng et al., 2004;Ha and Love, 2005;Harrill and Stringam, 2008;Stepchenkova et al., 2010;Xiang et al., 2010) or overall use of information technologies (Yuan et al., 2006). Other research areas include relationships with stakeholders (Ford, 2011;Ford et al., 2011;Lee et al., 2015), with meeting planners (Weber, 2001) or the types of research conducted by such institutions (Masberg, 2000). However, there are only few papers considering CB activity in a more complex way (Getz et al., 1998;Morrison et al., 1998;Wang and Fesenmaier, 2007) and even fewer studies compare CB's operation in different countries or regions (Palmer and Bejou, 1995). Although there are relatively not many investigations referring to CB, their analysis proves that it is hard to have a homogeneous point of view on these institutions. Natalia Latuszek is based at the Poznan University of Economics and Business, Poznan, Poland.
The research presented in this paper is focused on CB in North America and Europe because of their divergent genesis and development (Crouch and Weber, 2002;Ford and Peeper, 2008;Gartrell, 1988;Ogonowska, 2017;Rogers, 2013;Spiller, 2002). Therefore, the organisations on these two continents may play other roles in cities and local meetings industries. The roles of CB are discussed in scientific literature (Getz et al., 1998;Morrison et al., 1998;Wang, 2008), but the investigations are focused mainly on entities in North America. Moreover, it has not been stated yet which CB's functions and tasks are the most important. These issues were taken into consideration and a survey was carried out to answer the question, "What are the differences between the roles of CB in North America and Europe?" 2. Literature review

Definitions and roles of convention bureaux
First, the nature of CB should be defined because there is no complex and universal/ general explanation of its role in the meetings industry and in cities. Even the former vice president of Destinations International [2] claims that "A lot of consumers use CVBs, but don't have any clue what they do" (Slaton, 2013). Therefore, several definitions are collected in Table 1 to illustrate subtle differences between them. According to these definitions, CB can be seen as, for example, forms of tourism alliance (Palmer and Bejou, 1995), umbrella organisations (Masberg, 1998), information providers (Beaver, 2005) or brokers (Park and Kim, 2017;Yuan et al., 2006), destination developers and liaison between visitors and meeting planners and the host destination (Ha and Love, 2005) or a destination representative (Ha and Love, 2005;Maier and Johanson, 2013;Rogers, 2013). A misunderstanding can also arise because CB are often identified with destination marketing or management organisations, known as DMOs (Cobos et al., 2009;DMAI's empowerMINT. com, 2016;Fall, 2004;Feng et al., 2004;Getz et al., 1998;Wang and Russo, 2007;Xiang et al., 2010). Such an approach may be reasonable, because destination marketing or promotion lies at the heart of many definitions of CB (Ford and Peeper, 2008;Golden-Romero, 2007;Maier and Johanson, 2013;Marques and Santos, 2017;Palmer and Bejou, 1995;Rogers, 2013;Swarbrooke and Horner, 2001).
In contrast, in the UNWTO's (2010) report these two types of institutions are differentiated. Here a convention bureau is defined as "a specific form of destination governance at local or regional level" and as an "entity responsible for promoting and organizing conferences, exhibitions, conventions, incentives and various events at the destination", whereas DMOs are entities which unite the local tourism industry "to develop and promote the destination" (UNWTO, 2010, p. 4). Moreover, Gartrell (1988) and Masberg (1998) underline that city marketing is only one of CB' responsibilities. A similar point of view is held by Destinations Internationalconvention bureau focuses mostly on marketing, but its main mission is to develop cities in a long-term perspective (DMAI's empowerMINT.com, 2016).
In their operations, CB primarily deal with destination marketing, but many authors add wider context and indicate what purpose the marketing efforts should serve (Table 1). They should attract a higher number of events and visitors (Getz et al., 1998;Maier and Johanson, 2013;Marques and Santos, 2017), thus encouraging operation of local entrepreneurs (Lee and Lee, 2006) and finally contribute to fostering destination development (Gartrell, 1988). Another point of view is that a convention bureau acts as an information broker (Park and Kim, 2017;Yuan et al., 2006). Not only does it bring together local industry (Lee and Lee, 2006;Palmer and Bejou, 1995) but also supports communication outside the destination by providing information to meeting planners and visitors (Beaver, 2005;Ha and Love, 2005;Yuan et al., 2006). Moreover, a convention bureau can provide other services encouraging organisation of events (Baloglu and Love, 2005;UNWTO, 2010).

Visitors and convention bureaux
The visitors bureaux and CB can be regarded as the most developed form of local tourism marketing alliance in the USA. They vary in their authority and organisation and while most are nominally independent of government, some are administered as just another department within a county's authority. They also vary in size and responsibilities Getz et al. (1998), p. 331 Convention and visitors bureaux CVBs are primarily destination marketing organisations, typically established at the community level for the purposes of fostering meetings and leisure travel Masberg (1998), p. 67 Convention and visitors bureaux A CVB is a cooperative or umbrella organisation for tourism marketing, development and administration in cities and towns Swarbrooke and Horner (2001), p. 342

Their function is to provide information to conference organisers about facilities and services in this field available in their countries or areas, e.g. LCB, the London Convention Bureau. Sometimes called convention and visitors bureau, it means exactly the same Ha and Love (2005), p. 45

It is a type of organisation with a distinct structure and role, typically for urban destinations but also common for rural, coastal and mountain areas. A convention bureau is the entity responsible for promoting and organizing conferences, exhibitions, conventions, incentives and various events at the destination. It could be a non-profit private-public partnership, a company funded by the private sector, a department of public authority or even a private sector trading Maier and Johanson (2013), pp. 4-5

Convention bureaux
A convention bureau represents the city or local municipality in its desire to market the city and generate convention attendees based on promotional events and other associated activities. The convention bureau and tourism authority are usually an independent not-for-profit entity funded from several sources The variety of approaches presented in the definitions mentioned above indicates how many different roles CB can play in cities. According to the research conducted by Kova cevi c (2017), activities of this institution can be classified into three main categories:  (Gartrell, 1988;Getz et al., 1998;Morrison et al., 1998;Vallee 2008 after: Davidson andKeup, 2014) and propose their own lists of functions or operational areas. Wang (2008) summarises such lists and research and claims that CB can act in a city as a (Wang 2008, p. 194 Subject matter authors concentrate mostly on roles of CB in the local environment (except for Weber, 2001), whereas practitioners also stress their role for meetings organisers (DMAI's empowerMINT.com, 2016;Loomis, 2018). This is summarised by the President of Destinations International: "CVBs can show advantages to a destination that a planner may not have been aware of and wouldn't find anywhere else" (Loomis, 2018). All the issues mentioned previously show that convention bureau has a wide scope of activity and the differences among CB can be observed not only in the range of responsibilities but also organisational issues (Beaver, 2005;Palmer and Bejou, 1995;UNWTO, 2010).

History of convention bureaux
Differences in how the role of CB is understood may result from divergent genesis of this institution all over the world. Such organisations originated in the USA at the turn of 20th century ( Figure 1). Many factors (like urban development, transportation improvement, associations' foundation and growth) caused cities to attempt to attract association meetings because of the expected benefits from their organisation. Therefore, they started to employ full-time salespeople to travel around the country and encourage decision makers to organise their events in a particular city. For the first time this happened in Detroit in 1896, the year in which the first convention bureau is believed to have been founded. Soon the solution was applied in other cities. In the second half of the 20th century the institutions broadened the range of their activity and also focused on leisure travellers ( Figure 1). This transformation manifested itself in the change of the organisations' namefrom "convention bureaux" to "convention and visitors bureaux" (Ford and Peeper, 2008;Gartrell, 1988;Rogers, 2013;Spiller, 2002).
The meetings industry had similar growth potential in Europe. Even earlier the Congress of Vienna took place (1814-1815), which according to Rogers (2013) can be regarded as one of the first international congresses. However, further industry development was inhibited especially by the First and Second World Wars. This was also the case for the foundation of CB ( Figure 1). Although the first European convention bureau was established in 1905 in London (Marques and Santos, 2017), such organisations began to be established in the second half of the 20th century on the Old Continent and even later in Eastern Europeafter 1989 (Ogonowska, 2017;Rogers, 2013;Spiller, 2002).
Before the foundation of CB, DMOs were started in Europe. First entities were established at the same time as first CB in North America, because at the end of the 19th century DMOs started to operate in three Swiss citiesin Zurich, Basel and Bern (Seiser, 2008). As previously mentioned, the history of CB in Europe is shorter. Moreover, they were formed mostly as independent organisations specialised in the meetings industry. In consequence, two institutions existed in a number of cities: one responsible for leisure tourism (DMO) and

Differences between European and North American convention bureaux
The differences among CB are already indicated in their definitions and can stem from divergent genesis of such organisations all over the world. Distinctions may be seen mostly between institutions from Europe and North America. Ford and Peeper (2008, pp.12-22) emphasise that there are three key differences between these two groups of CB. These distinctions refer to: 1. size of institution and destination which it represents; 2. funding patterns; and 3. specific operational activities.
However, detailed analysis of authors' considerations shows that there are many more differences ( Table 2). They especially result from distinct operational areas, which is caused by two other ways of CB' foundation and evolution (both ways are described in the previous part of this paper). European CB' activities are focused mostly on business tourism or the so called meetings, incentives, conventions or conferences, exhibitions or events sector, whereas North American institutions also concentrate on the leisure tourism segment [3].
This means that entities in Europe operate in B2B relations (Leszczy nski et al., 2015) and US CB also capture the B2C market. However, research conducted by Destinations International on 521 institutions from all over the world shows that almost 75% of organisations capture both markets (Destinations International, 2019). According to Ford and Peeper (2008) European institutions are involved mostly at the stage of marketing and bidding for meetings, with a smaller contribution made to organising events. CB in the USA and Canada offer a wider set of services and need a higher annual budget and more employees than other CB (Ford and Peeper, 2008;Palmer and Bejou, 1995). According to Destinations International (2020), convention and visitors bureaux (CVBs) had a total budget of US$3.28m (it is the median destination organisation budget). Data on the budget of members of European Cities Marketing are not widely available.
Also, a funding pattern is different in Europe and North America. A common basis of American institutions' budgets is bed tax revenues (also called room or tourism  (2008), Getz (2003), Mutschlechner (2012) and Palmer and Bejou (1995) j INTERNATIONAL JOURNAL OF TOURISM CITIES j tax - Ford andPeeper, 2007, 2009). However, they can receive funding from other public or private sources (DMAI, 2015). The idea of bed tax was firstly reported in New York and established in Las Vegas (Wood 2002 after: Ford andPeeper, 2007) and the main concept refers to financing marketing efforts to attract new visitors from small amounts paid by tourists who had already come and spent a night in a particular city. This solution is becoming more common in Europe, but CB' budgets generally comprise fees from local members and grants received from governmental units (Ford and Peeper, 2008;Palmer and Bejou, 1995). The funding pattern is mostly related to the form in which a convention bureau was set up and its relationships with local governments and DMOs. Institutions in Europe and North America may have a wide range of organisational forms (DMAI, 2015;UNWTO, 2010) with most of them being non-profit (DMAI, 2015).
Geographical location also has other direct consequences for CB' operation. North American institutions focus more on national meetings because of the big domestic market ( Table 2; DMAI, 2015). Simultaneously, they differentiate the types of event to bid for. They are interested in associations meetings, corporate events and the Social, Military, Educational, Religious, Fraternal segment, but they are also open to sport, political and cultural events. For European CB international associations meetings are a priority [4]. This does not mean that they do not attract other events, but probably they must narrow their activities due to their limited financial and human resources. Moreover, US organisations generally represent bigger cities and have to manage bigger local networks of business and leisure tourism entrepreneurs and meet the needs of a higher number of stakeholders. The last difference is the fact that European CB are created at local, regional and national level (Beaver, 2005;Crouch and Weber, 2002), whereas there is no need to establish American Convention Bureaux.
Comparison was made based only on literature analysis and the author is aware that it is a big simplification, because on the one hand CB may strongly differ in one country, especially that there are approximately 1,450 organisations in the USA (DMAI's empowerMINT.com, 2016). On the other hand, distinctions between institutions all over the world may not be so sharp due to globalisation and international competition in which they are taking part. For example, European leaders on the meetings market like Paris or Vienna may share more similarities with big American cities than with a location on the same continent. Nevertheless, previous studies are a reliable source of information and the already mentioned differences refer to many European and North American CB (they show some general patterns), but obviously not to all of them.
The literature analysis confirms the need to conduct further research into convention bureau activity in various parts of the world. Moreover, there are several reasons why both scientists and practitioners may want to compare European and North American institutions empirically. Firstly, few studies focus on convention bureau outside the USA and Canada; therefore, organisations in other locations need further studies. Secondly, Palmer and Bejou (1995) prove that economical, political and social conditions in particular countries may affect convention bureau activity, for example, when it comes to meeting the needs of their stakeholders. Thirdly, Getz (2003, p. 9) claims that competitive advantage on the international meetings market can be achieved through one of the following main three strategies: 1. expand capacity; 2. improve quality; and 3. bid more effectively.
The first option is mainly beyond the scope of convention bureau. In the second case, they can only improve the quality of their own services or stimulate local industry through organising workshops and recommending standards. Thist means that they should concentrate mostly on bidding. Therefore, greater effort should be put into investigating the role of convention bureuax in this process. Moreover, international comparisons can be useful because they show differences between CB and thus potential source of advantage. It should help institutions to mark out cities they represent on the international meetings market. For new locations in this industry, this should provide some directions on how to enter international competition. It is important because, for example, according to Ogonowska (2017), Asian or African meetings industries show considerable growth potential.

Method
Because European and North American CB do not have the same origin and history and because there are differences between them as described in the subject literature, it is assumed that these institutions may play distinct roles in cities that they represent. However, this problem has not been researched yet. There are only few papers that refer to functions of CB and they focus on these organisations generally or on their regional characteristics. Therefore, the aim of the exploratory study presented in this paper was to investigate the differences between the roles of CB in North America and Europe.
The author narrowed the lists of CB' activities presented in literature to five main roles of such institutions: the agent, marketer, coordinator, representative of the meetings industry and leader. CB as agents represent their cities, especially when it comes to bidding for meetings. As was earlier presented in the definitions of this term, CB are also responsible for city promotion as meetings destination. Such actions need to be coordinated within the local meetings industry and lobbying for this sector in the city. CB may also play the role of a leader that guides the development of the industry. The roles mentioned previously were used in the survey to analyse the presumptive differences between European and North American CB.

Survey on convention bureaux' roles
A survey was part of a wider research project on the roles of convention bureau, coordinated by the author of this paper. The project was created to analyse the impact of CB on cities' competitiveness with special focus on Polish institutions. It included, inter alia, an international, online survey among representatives of CB from cities listed in an ICCA ranking. A questionnaire was sent to 290 managers in June and July 2016, with responses from 73 institutions. A total of 41 respondents represented Europe and 14 represented USA and Canada [5]. They were classified into further analysis in this paper. This group of respondents included presidents, vice presidents, directors and managers. Almost 42% of them held the highest position in CB. The rest of respondents managed sales department (16%), research department (9%), congress department (5%) or other departments (9%), for example, marketing, strategy and communication and fairs and exhibition departments) or provided no answer for this question. Further in this paper term "respondents" and "managers" will be used interchangeably Managers completed an emailed questionnaire that consisted of two parts. Firstly, respondents were asked about their opinion on the importance of CB' tasks and the way in which the institution that they represented fulfilled them. They used a list of twelve tasks, prepared on the basis of literature analysis and a five-point scale to assess the importance and performance of each activity. Every task was ascribed to one of the five roles of CB for further analysis (the list of tasks and roles is included in Table 3). In the next part of the questionnaire respondents provided general information about their organisations, for example, about the time of operation, organisational form, number of employees and annual budget.
The way in which the questionnaire was built enabled using the importance-performance analysis (IPA) in the further research steps. This method was originally designed for measuring consumer satisfaction with services, which was perceived as a combination of the importance of services' attributes and performance in providing them by a particular company or companies (Martilla and James, 1977). The IPA has already been used in a variety of research projects into, for example, tourism or business tourism area. The papers concerned, for example, the determination of a city's attractiveness in the meetings market (Go and Zhang, 1997) and the competitiveness studies or research into the attractiveness of tourist regions (Caber et al., 2012;Enright and Newton, 2004;Mihalic, 2013).
The biggest value of the IPA is that it is a transparent, graphical data presentation on IPA gird and researchers can offer practical recommendations. Each of the four squares on the grid is related to the proposed solution: 1. concentrate herea quarter with high scores of importance and lower performance; 2. keep up the good workhigh importance and high performance; 3. low priority (attributes)low importance and low performance; and 4. possible overkillhigh performance and lower importance.
In this project, the IPA was used to prioritise tasks of CB and to compare their roles in Europe and North America, which is an original attempt in case of this method. The quarters' boundaries in the IPA grid were calculated as mean values of the importance and performance for each group of CB (more information about the method can be found in Martilla and James, 1977). Moreover, the Mann-Whitney's U test was done to show the significance of differences between appraisals given by managers from Europe and North America. This test is suitable for comparing two small samples.

Sample characteristic
Data analysis started with characterising the sample. Further in the paper the following abbreviations will be used: European convention bureaux -CB; North American convention and visitors bureaux -CVB. Characteristics of both groups of institutions show the same differences as in literature analysis (Table 4). CBs are less experienced than CVBs because their average time of operation is almost three times shorter. When the research was conducted, CBs and CVBs had operated for 15 and 59 years, respectively. European entities also manage more limited resources. They employ nine people on average and European institutions are more diversified than North American entities when it comes to organisational forms (Table 4). CBs represent all forms listed in the UNWTO (2010) report, but both groups are dominated by non-profit public-private partnerships (more than half of all institutions taking part in the research). Respondents also frequently indicated the answer "others", which includes, for example, non-profit public or private entities, foundations and companies that are subordinate to tourist boards or other local governmental bodies. The last piece of information refers to the types of events that CB bid for. All institutions try to attract business events (meetings) and European entities are focused mostly on this type. CVBs diversify their actions and they also concentrate on sport, cultural and political events. In the category "others", respondents mentioned especially scientific-or university-related events and private events.

Results
Research primarily investigated on CB' tasks and roles in cities and local meetings industries. Its results are presented in Table 5, Figures 2 and 3 and they are fairly high, because all scores are above three-on a five-point scale. The most important task for CBs consists in answering the inquiries of events organisers (task no. 1). The same activity is characterised by the highest level of performance. High scores are also ascribed to city promotion (no. 12) and indicating the meaning of the meetings industry (no. 9). A similar situation occurs for CVBs, but the most important task is searching for request for proposals and making bids (no. 2). Promoting the destination (no. 12) is an activity performed to the highest extent. The lowest results of the importance and performance in both groups refer to mediating between entrepreneurs in the local meetings industry and related industries (no. 11).

Similarities
Boundaries on the IPA grid ( Figure 2) for both groups of CB are quite similar and the same recommendations are given to eight tasks. These suggestions refer mostly to continuation of previous activities. Efforts should still be focused on four tasks that are located in quarter B (keep up the good work). It includes tasks no. 1 (answering the inquiries of events   organisers/hosts), 2 (searching for request for proposals and making bids), 9 (indicating the importance of meeting industry in a city) and 12 (promoting the destination meetings industry product). Much lower priority (quarter C) is ascribed to three duties: cooperation with other CB (no. 4), mediating between meetings industry entrepreneurs and local government (no. 10) and mediating between entrepreneurs in the local meetings industry and related industries (no. 11). One task demands more concentration because of its location in quarter A (concentrate here). Institutions in both continents should pay closer attention to providing direction for local meetings industry's development (no. 5).

Differences
Different recommendations according to the IPAs interpretation should be provided for four tasks ( Figure 2). North American respondents claim that they need to focus more on conducting research on the local meetings industry (task no. 6 in quarter A), whereas for managers from Europe this duty has a lower priority (quarter C). On the contrary, CVBs pay less attention to tasks no. 3 and 8. Coordination of local meetings industry's activities and creation of local cooperation environment (no. 8) has no great meaning for CVB managers (quarter C), although European respondents see this activity as an important one and performed to the high extent (quarter B). They have the same opinion for task no. 3. For CVBs, mediating between event organisers and entrepreneurs from the local meetings industry (task no. 3 in quarter D) has a higher score for performance than importance; therefore, it may need special attention from managers, who maybe they should abandon this responsibility. A smaller difference in interpretation occurs for task no. 7, because creation of city meetings industry product is located in quarter C for CB and in quarter D for CVBs.
It was tested (using the Mann-Whitney's U test) whether differences between appraisals of tasks' importance and performance done by CB and CVB managers were significant (Table 5). Such results were achieved only for three cases: scores of importance for task no. 2 and 8 and performance for task. no. 9. This confirms that managers hold slightly different opinions as to the tasks performed by these institutions and does not change the way in which the IPA grid should be interpreted. However, the results underline the differences in the viewpoints on the meaning of coordination task of CB (no. 8). This also shows that CBs may slightly underestimate the role of active searching for requests for proposals and making bids (no. 2) and CVBs perform slightly better in indicating the importance of the meetings industry (no. 9), although both groups of institutions follow the same strategy for these two tasks.

Roles
Recommendations according to the roles of CB are quite similar for both groups of institutions ( Figure 3). The highest scores are ascribed to the function of marketer. The same quarter has results for the agent, but scores of this function are diminished by the scores for task no. 4 (cooperation with other CB). Respondents in both groups also hold the same opinion according to the role of representative, because this function has a low priority. CVBs should probably put less effort into acting as coordinators and focus more on being leaders in the local meetings industry. Recommendations for CBs for these roles are not so clear because the results for them are located near the boundary between quarters A and C.

Findings and discussion
It can be stated that the research results mostly confirm the current state of knowledge about the activity of CB. According to the majority of definitions of this term, the main operational area is city marketing (Ford and Peeper, 2008;Golden-Romero, 2007;Maier and Johanson, 2013;Marques and Santos, 2017;Palmer and Bejou, 1995;Rogers, 2013;Swarbrooke and Horner, 2001), together with attracting events (Gartrell, 1988;Getz et al., 1998;Lee and Lee, 2006;Maier and Johanson, 2013;Marques and Santos, 2017). Being an information broker (Park and Kim, 2017;Yuan et al., 2006) or a liaison (Ha and Love, 2005) between the local meetings industry and events hosts is more about answering the inquiries, making bids and searching for request for proposals than mediating in relationships between entrepreneurs and associations. Therefore, the role of CB should be more fundamental at the early stages of winning a meeting and less important during the negotiations and event organisation. Simultaneously, this does not mean that other functions of such institutions or their operational areas listed in literature (Getz et al., 1998;Kova cevi c, 2017;Wang, 2008) or used in the research are meaningless. The results show that they are also important but they play a supplementary role to the function of marketer and agent.
According to the distinction between European and North American CB, characteristics of both groups confirm many differences among them and the dissimilarities correspond to those resulting from literature analysis (Ford and Peeper, 2008;Getz, 2003;Mutschlechner, 2012;Palmer and Bejou, 1995). This can be caused by the divergent origin of institutions on both continents and the longer history of entities in the USA and Canada may contribute to higher employment and annual budget, as well as to the wider set of attracting events (political, sport, cultural besides the business ones). European CB are more diversified in their organisational forms. Such a situation probably refers to the different legal and political conditions in other countries and the existence of similar institutions at regional or national level. It should be noted that only a few differences were indicated in the survey and this topic needs further in-depth studies, including the reasons of divergence, too.
However, the organisational differences are not reflected in the operational area and the contrast in the case of tasks and roles is not as sharp and clear as can be supposed. The study in this area stands in contrast to research by Palmer and Bejou (1995), who claim that there is a difference between USA and UK institutions. Roles and tasks of European and North American CB are similar and differences probably lie in the range of activity and the way in which they fulfil their detailed responsibilities. It might be only assumed that activity of CB and visitors bureaux is more diffused because of the wider scope of operation (combining managing business and leisure tourism).
Nonetheless, two roles are clearly distinguished from others: the function of the agent and marketer and these two were characterised by the highest importance and performance, which is also the case for CB from Europe. North American institutions are a little bit more active in attracting meetings, because searching for request for proposals is more important than answering the inquiries. In both groups, less attention was paid to the role of representative, which mostly consists in indicating the meaning of the meetings industry in a city. Apparently, this results from the long history of CB in the USA and Canada, but the same situation occurs in European institutions. Therefore, a well-established position of convention bureau in a particular city may be behind such a state of affairs. Moreover, part of entities in Europe acts as a department of public authority and perhaps they are automatically involved in mediating in relationships between local government and entrepreneurs.
The priority roles of the agent and marketer assume that CB can achieve the greatest by concentrating on bidding following the three strategies listed by Getz (2003). Focus on these functions should result in attracting a higher number of more valuable meetings and lead to the development of a city (Gartrell, 1988;webinar). This is also a suggestion as to what kind of tasks new institutions or organisations should take on in the first place. It is necessary to participate in international competition. Other responsibilities may have a different meaning in cities with a differing level of development of the local meetings industry. Moreover, excellent performance in both bidding for meetings and other services can be a source of competitive advantage.

Conclusion
This paper contributes to the scientific literature on the roles of CB by identifying differences between organisations in North America and Europe. The research results show that both group of institutions play similar roles, but entities differ mostly in how they evaluate particular tasks. The dissimilarities are probably more a result of local conditions (e.g. structure of meetings industry) in a city that a convention bureau represents than common history of foundation on one or another continent. However, the operational differences are strongly apparent, especially when annual budget or number of full-time employees is compared.
When all the matters are taken into consideration, it can be stated that setting up a new convention bureau or functioning of an institution with very limited resources should be primarily focused on fulfilling tasks typical of the role of an agent and marketer. Also, the organisational form should be chosen wisely to enable playing these two roles. Nonetheless, at the beginning of operation, local entrepreneurs, government and other institutions may need to be integrated; therefore, CB may put more effort into communication, building relationships in the meetings industry, representing it in a city and coordinating joint activities. City promotion, answering the inquires, searching for request for proposals and making bids should be convention bureau's priority, and the meaning of other tasks probably depend on local circumstances.
Therefore, activity of CB needs further examination. Analysis of operational forms (public-private partnership and local government unit) rather than geographical location may show clearer and sharper differences. Managers should be asked about barriers, because they might want to undertake some activities, but for particular reasons they cannot do that. In this research, it was assumed that limited resources narrow operational scope, but this may require more attention. Support of local government, engagement of entrepreneurs and existence of tourism dedicated DMO, convention bureau at regional or national level and other similar institutions may have a strong impact on activities of a particular convention bureau and should be included in analysis of local circumstances. Another issue that needs investigation is a point of view of stakeholders concerning the function of CBhow they see the role of such an institution and which tasks are the most useful for them. A survey concentrated on this topic will probably be valuable for both: researchers and practitioners.
The survey presented in this paper was conducted on a relatively small sample and it included a limited list of potential differences. The IPA also has its limitations. Some issues like the definitions of importance, a correlation among attributes or interpretation of the results are debatable (Oh 2001). However, this research attempts at analysing differences between CB and it suggests which tasks and roles should be treated as priorities and which ones have supplementary or marginal meaning. The IPA may also suggest that concentration on some tasks (e.g. strong focus on conducting research) may create a chance to stand out and build competitive advantage. Therefore, despite its limitations, the author believes that the proposed examination provided insight into the importance of analysis on the convention bureau's roles and its comparison among different countries or continents.
