The purpose of this paper is to propose an integrated model for allocation and leveling of human resources in IT projects.

A single case study was conducted in a large company of IT outsourcing services, which were assessed the management of 14 projects. The survey was conducted through interviews with project managers, and digital files and internal documents of the organization related to these projects.

In the analysis, it was identified that the critical path is not identified in all projects, and even when this happens, resources are not allocated in the first tasks in that path. A committee controls the allocation of resources with the assessment of skills, but there is no control of all resource constraints.

The main limiting factors for this study are: use of data of one company in the IT industry, making it difficult to generalize the model for other sectors companies; it was noted during interviews that the project managers interviewed do not always know in detail all the company’s processes for allocation and resource leveling, due to the large number of processes and different management activities of these professionals.

A model and actions for this implementation was proposed, such as training for the use of the technique of critical path; allocation and leveling done simultaneously; decisions of the management committee based on information of availability, key skills, holidays, days off of human resources; development of a software tool that integrates this information, generating graphical interfaces that are not provided by project management software with the use of an allocation factor.

The characteristics of the proposed model, as well as the use of the allocation factor, can help managers to validate their allocation models and leveling of human resources in an integrated manner.

The study explains that the granularity of analysis of resource allocation increases by decomposition of the duration of each activity in fixed time segments. It is suggested to use the mathematical concept of the allocation factor (F_a).

The technique of Critical Path Analysis (CPA) and its applications are described. A simple example is used to illustrate the method. The use of CPA in the implementation of an automated lending system at Teesside Polytechnic Library is described.

Suggests that, although the potential value of network analysis to aid marketing decisions has been recognised, there is a need for a reappraisal of the procedure in a marketing environment, in particular the distinction between the planning and control possibilities of networks. Includes an examination of the reasons why some disenchantment exists with the technique and presents the fundamentals of the approach. Weighs up that the marketing function is an area into which inflexible techniques of management do not fit easily, but has attempted to demonstrate network analysis may be used in a way making it relevant to the marketing decision – particularly at the planning stage.

Introduction Operations research, i.e. the application of scientific methodology to operational problems in the search for improved understanding and control, can be said to have started with the application of mathematical tools to military problems of supply bombing and strategy, during the Second World War. Post‐war these tools were applied to business problems, particularly production scheduling, inventory control and physical distribution because of the acute shortages of goods and the numerical aspects of these problems.

Construction projects commonly encounter complicated delay problems. Over the past few decades, numerous delay analysis methods (DAMs) have been developed. There is no consensus on whether existing DAMs effectively resolve delays, particularly in the case of complex concurrent delays. Thus, the primary objective of this study is to undertake a comprehensive and systematic literature review on concurrent delays, aiming to answer the following research question: Do existing delay analysis techniques deal with concurrent delays well?

This study conducts a comprehensive review of concurrent delays by both bibliometric and systematic analysis of research publications published between 1982 and 2022 in the Web of Science (WoS) and Scopus databases. For quantitative analysis, a bibliometric mapping tool, the VOSviewer, was employed to analyze 68 selected publications to explore the co-occurrence of keywords, co-authorship and direct citation. Additionally, we conducted a qualitative analysis to answer the targeted research question, identify academic knowledge gaps and explore potential research directions for solving the theoretical and practical problems of concurrent delays.

Concurrent delays are a critical aspect of delay claims. Despite DAMs developed by a limited number of research teams to tackle issues like concurrence, float consumption and the critical path in concurrent delay resolution, practitioners continue to face significant challenges. This study has successfully identified knowledge gaps in defining, identifying, analyzing and allocating liability for concurrent delays while offering promising directions for further research. These findings reveal the incompleteness of available DAMs for solving concurrent delays.

The outcomes of this study are highly beneficial for practitioners and researchers. For practitioners, the discussions on the resolution process of concurrent delays in terms of identification, analysis and apportionment enable them to proactively address concurrent delays and lay the groundwork for preventing and resolving such issues in their construction projects. For researchers, five research directions, including advanced DAMs capable of solving concurrent delays, are proposed for reference.

Existing research on DAMs lacks comprehensive coverage of concurrent delays. Through a scientometric review, it is evident that current DAMs do not deal with concurrent delays well. This review identifies critical knowledge gaps and offers insights into potential directions for future research.

The merchandising process of a large buying office in Hong Kong was studied using a network analyses tool, programme evaluation and review technique (PERT). Quantitative and qualitative data were both obtained by in‐depth interviews with key people in the company. The delivery lead time, which was the cycle time from the receipt of an order by the buying office to the point where the garment lot was ready for shipment at the manufacturer’s factory, was determined quantitatively, and probabilities of late shipments analysed. For bulk orders of woven garments, the activity time of fabric manufacture and garment manufacture was found to account for about half and one‐third, respectively, of the total delivery lead time (about 69 days). Also the PERT was shown to help identify critical activities which were redundant and thereafter, through process re‐engineering, could shorten the delivery lead time and reduce the work load of the merchandiser.

The purpose of this paper is to disentangle and elaborate on the constitutive elements of the concept of path dependence (initial conditions and lock‐in) for a concerted and in‐depth application to the study of organizational change.

The approach takes the form of a combination of a longitudinal and a comparative case‐study, based on secondary literature.

External initial conditions acted less as “imprinting” forces than is suggested in the literature on the genesis of the Toyota production system (TPS); a firm‐specific philosophy in combination with a critical sequence of events mainly shaped and locked‐in TPS.

The empirical sources are limited to publications in English, so relevant factors explaining the path taken may not all have been included. The importance of a salient meta‐routine might be firm‐specific.

The study contributes to understanding the factors underlying corporate performance by a critical re‐examination of a much heralded production system (TPS).

The paper highlights the use of the concept of meta‐routines to connect the core elements of path dependence, that is, sensitivity to initial conditions and lock‐in mechanisms.

The purpose of this paper is to analyse the concepts of sustainability, responsibility and ethics focussing on their links and differences, also to understand how companies move respectively in these field; to understand how companies sometimes move away from the basic and deep meaning of these concepts, landing in a merely utilitarian sphere of personal advantage where ethics, instead of being an irreplaceable and essential stronghold, is found to be a fiction or just an instrument.

The methodology used assumes a theoretical critical approach and, based on the vast literature on the items, is based on a conceptual analysis of the themes of sustainability, corporate social responsibility (CSR) and ethics and of the behaviour that companies can adopt in the three contexts. A critical approach to these issues and concepts can effectively help us to understand how companies are responding to external demands and to the challenges of responsibility and sustainability, which are becoming increasingly pressing.

Ethics, sustainability, CSR and social and environmental reporting are distinct constructs with different meanings but linked by important conceptual and operational relationships.

The results of the research are the consequence of the application of a critical approach based on a theoretical analysis of the concepts under study. It would be interesting to support the results achieved with empirical research studies.

This conceptual path helps scholars and companies themselves to understand the difference between the three key concepts analysed. Only by understanding the basic meaning will it be possible to really make one’s own and pursue it in the correct way.

Nowadays, the authors are overwhelmed by these three concepts which are used as synonyms and incorrectly. This leads to confusion and misunderstandings. Knowledge of the characteristics and differences between these concepts and their concrete applications is of great importance.

This study tries to provide a critical discussion of how the three concepts intersect and differentiate, leading to concrete results or results that have nothing to do with their meaning. There are no conceptual papers in the literature that deal with the three concepts and also analyse the implications on the real world.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

The paper describes four methods of dealing with delay claims that effectively sum up the main approaches to this problem that have been offered in the literature. This is then followed by a description and discussion of results from a new survey aimed at finding out exactly how professionals in the UK construction industry approach these difficult issues. It appears that those who deal with delay claims in the UK are likely to use a critical path method network to do this and generally approve of a methodology that attempts to understand how well the contractor would have fared ‘but for’ the existence of employer‐responsible delays. There is less agreement about who should be said to own the float, but as is explained in the paper, it is possible for this matter to be dealt with by the insertion of a clause in the contract documents.
