The purpose of this study is to identify a typology of procurement contracts in the context of software development projects that allows firms to align design flexibility with design uncertainty at the project level. The theoretical lenses of contract theory and software engineering are used to explain why the five archetypes in the proposed typology provide gradually increasing levels of design flexibility and to develop hypotheses about the associations between design flexibility and a set of project cost dimensions.

The hypotheses are tested with objective contractual data from 270 software development contracts entered into by a leading international bank over a period of three years.

Data analysis confirms the existence of the proposed typology and shows that design flexibility is negatively associated with control and positively associated with coordination, trust, duration and price.

Although the findings are based on the contracting practices of a single, albeit sophisticated, organization, they shed light on the ability of firms to align flexibility with uncertainty at the onset of new projects by taking advantage of nuanced contractual mechanisms to produce a broader set of contractual archetypes.

This paper is the first in the outsourcing literature to analyze a nuanced contractual typology in software development projects through the perspectives of both contract theory and software engineering.

The COVID-19 pandemic resulted in the compulsory quarantine of many of the world's inhabitants, and by staying at home, several functional developments emerged in residential spaces in Jeddah that affected the role of the house as a contributor to individuals' quality of life under the pressures of quarantine. Given the necessity of the apartments to adapt to these emerging developments, this study explores the determinants associated with the flexibility of residential apartments by looking at the extent to which they meet the new psychological, social and cultural roles required by their users post-COVID-19.

The qualitative approach (1) extracted concepts related to the flexibility of housing from the available literature and (2) extrapolated the flexibility of the residential apartments from the participants' study (12 families) in different areas of Jeddah by analyzing the results of targeted interviews.

There is a gap in the participant's understanding of the quality of housing and the level of satisfaction with a housing design that differs before and after their quarantine experience. The participant's adaptation to self-quarantine was mainly through furniture distribution, and housing flexibility was less reliant on the physical transformation of the place than on the change in the inhabitants' perceptions. There was an indication that the deficiencies of flexibility in design relates to the functional, cultural and structural aspects of residential buildings.

This study generated suggestions to develop the foundations for flexible housing design and activate its role under the post-quarantine context according to social and cultural variables. Some proposals should become future requirements for residential apartments to benefit officials and stakeholders to develop housing flexibility.

The recent shift towards accommodating flexibility in manufacturing companies and the complexity resulting from product variety highlight the significance of flexible assembly systems and designing products for them. The purpose of this paper is to provide insight into the requirements of a flexible assembly system for product design from the assembly system’s standpoint.

To fulfil the purpose of the paper, a literature review and a case study were performed. The case study was conducted with an interactive research approach in a global market leader company within the heavy vehicle manufacturing industry.

The findings indicate that common assembly sequence, similar assembly interfaces, and common parts are the main requirements of a flexible assembly system for product design which reduce complexity and facilitate various flexibility dimensions. Accordingly, a model is proposed to broaden the understanding of these requirements from the assembly system’s standpoint.

This study contributes to the overlapping research area of flexible assembly systems and product design.

The proposed model is largely based on practical data and clarifies the role of product design in facilitating flexibility in an assembly system. It can be used by assembly managers, assembly engineers, and product designers.

The key originality of this paper compared to the previous studies lies in presenting a novel assembly-oriented design model. The model enhances understanding of a flexible assembly system’s requirements for product design with regard to reducing complexity and managing variation in a flexible assembly system. These requirements can be applied to product design across various product families within a company’s product portfolio.

The purpose of this paper is to explore the interplay between firm boundary decisions and the management of both efficiency and flexibility and the implications this has for modular design in the provision of advanced services.

A single case study in the defence industry employs semi-structured interviews supplemented by secondary data. Data are analysed using thematic analysis.

The findings provide a process model of boundary negotiations for the design of efficient and flexible modular systems consisting of three phases; boundary ambiguity, boundary defences and boundary alignment.

The study provides a process framework for boundary negotiations to help organisations navigate the management of both-and efficiency and flexibility in the provision of advanced services.

Drawing upon modularity, paradox and systems theory, this article provides novel theoretical insight into the relationship between firm boundary decisions and the management of both-and efficiency vs. flexibility in the provision of product upgrade services.

When competing in a turbulent environment, strategic flexibility can be a competitive advantage. One source of flexibility is the new product development (NPD) process, or more specifically product design. The purpose of this paper is to investigate platform-based product design and its relationship to environmental turbulence, strategic flexibility, and market performance.

A theoretical model is developed and relationships are empirically tested using structural equation modeling. Data were collected from engineering design managers in the US manufacturing industry.

The paper found that the higher the level of environmental turbulence the more firms turned to platform product design. Also, the higher the level of platform design the higher the level of market performance, both in the short term and the long term. Finally, the paper showed that strategic flexibility positively and partially mediates the positive relationship between platform design and performance.

Platform-based product design is a research area noticeably devoid of empirical work. Furthermore, research has called for a better understanding of the different contexts in which platforms are applied stating that platform planning is too often decoupled from NDP strategy resulting in unsatisfactory results.

The purpose of this paper is to provide an understanding of how the materials feeding design at a workstation impacts the assembly process performance, in terms of manufacturing flexibility, process support, materials planning and work task efficiency.

The empirical data are based on two embedded case studies performed in close corporation with two Swedish automotive companies; additional observations from more than 20 company visits in Japan, and small‐scale case studies performed in Japanese companies. To fully assess the work measurement figures, video recordings, work instructions and layout drawings were used to plot the operators' walking patterns, and it was then possible to map the whole work cycle for an operator. Industrial engineers, managers, group leaders, team leaders and operators were interviewed. Based on the literature review and personal experience from the small‐scale case studies carried out in Japan, the existing assembly systems' component racks were conceptually re‐designed. This led to two hypothetical assembly systems, which could be used for understanding the impact of materials feeding design on assembly process performance. The design of the new component racks and the choice of packaging types were made together with practitioners.

The paper shows that the design of component racks and choice of packaging types have a major impact on the assembly process performance. Component racks with a large depth and small width and tailored packages create important advantages over traditional Swedish component racks designed for EUR‐pallets. Line stocking is not always the best choice for materials feeding, but this paper shows that line stocking, especially in Swedish assembly systems, can be improved. Sequencing can thus be reduced, resulting in fewer problems when there are sequence breaks in the production flow. Component racks with small packages and large depth increase the work task efficiency, volume, mix, new products and modification flexibility. For example, free space is an important issue for these types of flexibilities. Component racks that are portable and easy to rearrange, together with free space, greatly facilitate handling of new product introductions or modifications of products. The new and old component can be displayed and fed to the same workstation, and if there is a larger change a whole segment of a component rack can easily be replaced by a new one between work shifts.

The scope of the study is limited to the conditions at workstations. Consequences for the materials flow upstream (i.e. internal materials handling, warehousing, transport, supplier processes, etc.) are not included, but must in further studies also be considered to avoid sub‐optimisation.

The paper highlights the fact that a shift in focus is necessary when designing workstations with component racks in Swedish companies, meaning that operators become the customers rather than the transport company or materials handler.

The purpose of this paper is to highlight the importance and significance of design strategies to enhance flexibility as an in-built design concept of residential building in developing countries. The study considers potential directions of building design in developing countries to ensure maximum benefits of resource utilization.

The study approaches using the qualitative data collection method, mostly based on interviews of local residents. Layouts of residential buildings that have been renovated for several reasons, such as the changes in family size over the last 30 years, have been studied. The concept of zone and margin, based on the theoretical framework developed by Dutch architect, John Habraken, is compared and tested in residential buildings in the city of Khulna.

This paper shows that people change floor layouts of their buildings over time for different reasons; for example, 29 percent of people change plans in order to accommodate more people, 19 percent in order to initiate new businesses, and 13 percent due to change in family structure. However, these facts impose an excessive monetary burden on the owners to re-adjust layouts even though the building does not have the provision to do so. The paper also reveals that people would welcome new plans for future readjustment during the design and construction phases instead of renovation phases.

This paper highlights flexibility and attempts to justify the possibilities to practice in developing countries. As an inherent design strategy of sustainable development, the concept would consider unknown future changes of building layouts and structures. It would consider the minimum reconstruction, or renovation, costs associated for future adaptation.

The purposes of this study are to prove that the content of floor flexibility can be designed objectively with the use of margins, which are an architectural vocabulary visualizing the possibility of formal change, and to conduct a case study on how the existing typical floor plans of South Korean apartments change with the extension of flexibility: the usability of margins and the results.

This study reviews two housing projects with different methods of flexible housing design: one is the flexibility to change the sizes of spaces and the other is the flexibility to change the topology of spaces. In this paper, the architectural term “area margin” is used for the former and “linear margin” for the latter. These were applied to the case of current apartments in South Korea to transform them into floor plans with the two types of flexibility and investigated whether the proposed floor plans satisfy the required efficacy structurally and functionally.

This case study shows that margins can be used as architectural vocabularies representing flexible sizes of rooms and flexible boundaries with neighbors. The final form of the structural framework became homogeneous, even though it conserved its indigenous spatial characteristics of abundant natural sunlight and airflow. In addition, the transformed structural framework has higher rigidity than the original one, even though the transversal wall was cut off with a margin, as shown by the schematic representations in this paper.

The alternative plan, designed as a modification process, is not representative as a flexible floor plan. Rather, it is thought more important to make a range of variations rather than prototyping a model. This study starts from the premise that it is desirable for apartment house plans to share and encourage variations rather than aiming at typical sizes and shapes. Furthermore, this study exemplified the process to modify the existing typical floor plan into a flexible one using margins. Through this modification, it is thought that the typology of the South Korean apartment, which has succeeded in gaining social consensus for half a century, can be preserved while accommodating social changes in the future.

The control of future variations of floor plans will extend the socioeconomic and physical life of a building, enabling a reasonable reinvestment of resources.

This paper deals with a design method applying distinct visual symbols to different contexts of flexibility and using those as architectural vocabularies.

This paper focuses on understanding the contribution of Industry 4.0 technologies to manufacturing flexibility.

A multiple-case study was conducted through interviews and complementary data from 12 adopters of Industry 4.0 technologies from the industrial sector. To enable a broad perspective, cases from 5 industry sectors with different technological intensity levels were studied.

The findings show that Industry 4.0 technologies are mostly used to improve machine flexibility since there is a major focus on technological approaches rather than on wider flexibility. The results also showed that cloud services, IoT, and data analytics provide the basis for flexible operation, and collaborative robots, ERP/MES/PLM, AGVs, and traceability devices are the most commonly implemented technologies for flexibility. However, inherent contingency factors such as production complexity and product life cycle need to be considered.

This article expands the research on manufacturing flexibility, considering new capabilities introduced by Industry 4.0.

The purpose of this paper is to investigate factors influencing manufacturing flexibility adoption and simultaneously explores some of the key issues prevailing in manufacturing flexibility adoption in Indian context. The study also stratifies critical factors for successful manufacturing flexibility adoption.

Using exploratory sequential design, a series of focus group interviews were conducted with Indian manufacturing professionals and these interviews were supplemented by 127 follow-up structured questionnaires.

Two major themes emerged from the first phase of the study – role played by some of the unexplored antecedents of manufacturing flexibility and key issues in manufacturing flexibility adoption. In the second phase, a list of factors was categorized based on their degree of importance in manufacturing flexibility adoption.

Being qualitative in nature, the study suffers from inherent risk of subjectivity associated with manufacturing practitioners. A large-scale survey and rigorous quantitative analysis would be helpful to further validate the list of factors and underlying relationships among proposed factors.

The identified list of factors and some of the key issues in manufacturing flexibility adoption can be of great help to practitioners. The stratified list of factors can be further used by academicians to develop an instrument for manufacturing flexibility adoption.

The paper identifies a set of factors that affects manufacturing flexibility adoption. It offers a basis for instrument development for manufacturing flexibility adoption and provides direction for future quantitative research in manufacturing flexibility area.
