Context. Situational Method Engineering (SME) is the discipline that aims at the systematic definition of methods adapted to specific contexts of use (situations). The use of goal-oriented methods for supporting SME is an active research line where the iStar 2.0 language is applied. Objective. We plan to conduct an experiment to investigate some de...

Il s'agit ici d'un résumé étendu de notre article (Ralyté, Léonard, 2019). Pour réussir, la transformation numérique ne peut pas être considérée comme relevant d'un seul département ou d'une seule organisation. Sa mission consiste à fournir de nouveaux services d'information interdisciplinaires voire transdisciplinaires. L'intelligence collective e...

To be successful, Digital Transformation cannot be considered as a matter of a single department or a single organization, regardless of whether the organization is private or public. Its mission consists in providing new inter-disciplinary or even trans-disciplinary information services. Therefore, collective intelligence is a key for its success....

The progress of Society depends largely on the success of its digital transformation, i.e. on the development of digital infrastructure taking form of information services. Moreover, the challenge consists in building interdisciplinary or even transdisciplinary information services and service systems. Given the variability of activities to conside...

Situation and intention are two fundamental notions in situational method engineering (SME). They are used to assess the context of an ISD project and to specify method requirements in this context. They also allow defining the goals of the method chunks and the conditions under which they can be applied. In this way, the selection and assembly of...

Enterprise Modeling (EM) addresses business-IT alignment in a holistic manner by providing the techniques, languages, tools and best practices for using models to represent organizational knowledge and information systems from different perspectives. Complex business and technology conditions means that EM plays an important role in reaching such...

Sustainability of enterprise Information Systems (ISs) largely depends on the quality of their evolution process and the ability of the IS evolution steering officers to deal with complex IS evolution situations. Inspired by Olivé [1] who promotes conceptual schema-centric IS development, we argue that conceptual models should also be the centre of...

Management of Quality Requirements (QRs) is determinant for the success of software projects. However, this management is currently under-considered in software projects and in particular, in agile methods. Although agile processes are focused on the functional aspects of the software, some agile practices can be beneficial for the management of QR...

Evolution is characteristic to all enterprise information systems (IS) because of continuing changes in its environment. It is also a necessary condition for guaranteeing IS fitness to the organizational needs and requirements. Nonetheless, each IS evolution presents several risks towards their sustainability and requires an accountable steering. I...

Information System (IS) evolution is today a continuous preoccupation of every modern organization that aims to have a perfect support for its constantly changing business ecosystem. However, the task of IS evolution is not anodyne, it presents several risks towards IS sustainability as well as towards enterprise activity. Taking a decision related...

Organizations are increasingly becoming Open Source Software (OSS) adopters, either as a result of a strategic decision or just as a consequence of technological choices. The strategy followed to adopt OSS shapes organizations’ businesses; therefore methods to assess such impact are needed. In this paper, we propose OSSAP, a method for defining OSS...

Service-oriented paradigm is emerging as a promising solution to handle enterprise information systems (IS) complexity, interoperability, and evolution issues. However, the shift from a conventional IS architecture to a service-oriented one is not an easy task. Various approaches have been proposed in the literature and most of them deal with eithe...

Evolution is characteristic to every Information System (IS) because of continuing changes in its environment. It is also a necessary condition for guaranteeing IS fitness to the organizational needs and requirements. Nonetheless, each IS evolution presents several risks towards its sustainability and further changes, and steering IS evolution is i...

Formalised systems development methods are used in systems development as a means to express and communicate knowledge about the systems/software development process (Ågerfalk and Fitzgerald 2006). Since methods are social constructs, they embed various assumptions about people and systems development as a social practice (Introna and Whitley 1997;...

So far, we have discovered how to create method parts and what sort of underpinning formalisms are available; now we address the construction aspects, i.e. how to create a full, industry-strength methodology for software development from these method parts. This may be accomplished in a bottom-up fashion, starting with the identification of method...

In this chapter, we present four different examples of the application of the ideas of SME presented in the first eight chapters. Situational method construction often begins with team members identifying ‘on paper’ method fragments from a repository. In our first example (Sect. 9.1), we do just that by constructing a medium-sized methodology using...

In Chap. 1, we used the name ‘method part’ to refer generically to some piece of a methodology smaller than the whole methodology. In the research literature, many names have been used, sometimes with the same semantics, sometimes the same name with different semantics. However, the bulk of the literature talks of (1) method fragments, (2) method c...

One of the least understood aspects of situational method engineering is quality assessment. Here, we are concerned firstly about the quality of individual method parts (fragments, chunks, components) as they are stored in the method base, the overall quality of the method base itself in terms primarily of cohesion and the quality of the method tha...

In the earlier chapters of this book, we have introduced a comprehensive review of the state-of-the-art in situational method engineering. However, over the last few years, there have been published a number of new ideas that are highly relevant to SME. In particular, we highlight in this chapter just three of these: how SME support service-oriente...

In this chapter, we look at formal ways of addressing situational method engineering, method parts (fragments, chunks, components, etc.) and method construction. In Sect. 4.1 we discuss various metamodelling approaches at a variety of scales, from full method to single fragment descriptions. Section 4.2 is a brief discussion on ontologies and the u...

The growing popularity of new mobile information technology products influences enterprises to buy them without an appropriate evaluation of their usability. This situation is relatively new and conventional usage driven requirements engineering approaches are not well suitable. The objective of our work is to propose a technology-driven requiremen...

Les difficultés d’utilisation de l’ingénierie des méthodes situationnelles (IMS) dans l’industrie sont dues essentiellement à la complexité des solutions proposées et l’IMS cherche de nouvelles voies pour faciliter la construction des méthodes spécifiques au contexte. Une piste possible vient de l’ingénierie des lignes de produits logiciel (LdP) qu...

While previously available methodologies for software – like those published in the early days of object technology – claimed to be appropriate for every conceivable project, situational method engineering (SME) acknowledges that most projects typically have individual characteristics and situations. Thus, finding the most effective methodology for...

In the first few chapters, we have set the scene by defining, both informally and formally, the ideas behind situational method engineering in terms of method fragments, method chunks, method components and method rationale. We have also briefly discussed issues of granularities and interfaces. However, we have to date neglected to answer the vital...

The history of situational method engineering as a subdiscipline of software engineering is around 20 years old. Increasing recognition that a one-size-fits-all methodology has led to increased interest in other options—specifically, the construction of a methodology from smaller method parts, those parts being chosen with the specific context or s...

Having constructed a method using an SME approach, the first enactment should follow smoothly, since all situational constraints have been accommodated during its construction. However, on later endeavours, minor ‘tweaking’ may become necessary. Sometimes, management may decide to ‘freeze’ a base method upon which such modifications are to be made....

Service-orientation is currently considered as a promising paradigm to deal with the complexity, interoperability and evolution of enterprise Information Systems (IS), which are the foremost preoccupation in today’s enterprises. However, the shift from a conventional IS architecture to a service-oriented one is not an easy task despite of the vario...

The competitiveness and efficiency of an enterprise is dependent on its ability to interact with other enterprises and organisations. In this context in- teroperability is defined as the ability of business processes as well as enterprise software and applications to interact. Interoperability remains a problem and there are numerous issues to be r...

Increasing popularity of the notion of service in the enterprise business and information systems development facilitates the creation of new types of inter-organizational and multidisciplinary collaboration and value co-creation. Simple exchange of services between organizations evolves into the co-creation of transdisciplinary services shared by...

In this paper we report on our experience in the application of the assembly-based situational method engineering approach in prac-tice. In particular, we demonstrate the construction of a situation-specific method for a small size company operating in the domain of e-commerce. The aim of this work was to help the company to specify its business mo...

Situational Method Engineering (SME) is constantly looking for new ways to facilitate situation-specific method construction in practice. We have developed the notion of method family to attain this goal. Our inspiration comes from Software Product Line Engineering (SPLE), which is developing solutions that can be easily adapted to a specific conte...

This chapter is an overview of the development of the information sys-tems domain since its infancy. This domain is recognized as very important for the development of private companies and public organisations and therefore it more and more needs solid concepts and sharp ways of thinking. This chapter relates some breakthroughs and tries to place...

While service-oriented paradigm plays a more and more extensive role in software and information systems development and service-driven architectures are increasingly adopted by public and private organizations, the Requirements Engineering (RE) discipline still fails to provide approaches and techniques dedicated for this type of development. In t...

Increasing popularity of the notion of service in the enterprise applications development leads to the new types of inter-organizational collaborations. We can observe a shift in this collaboration from simple exchange of services to the co-creation of transdisciplinary services offering a new and unique value to the involved partners.

Continuous changes and extensions of enterprise information systems (IS) are the main causes of their fragmentation and redundancy. The notion of service and service-oriented engineering emerges as a prospective approach to deal with IS evolution. The shift form IS to information services systems (ISS) requires to re-think the fundamentals of IS de...

The situational method engineering (SME) literature is surveyed and a synoptic evaluation presented in the context of formalizing and regularizing the conceptual framework and underpinning theory. Metamodels proposed for use in SME are evaluated as well as highlevel process models for method construction. Method fragments and method chunks are then...

Requirements engineering has long acknowledged the importance of the notion that system requirements are stakeholder goals - rather than system functions - and ought to be elicited, modeled and analyzed accordingly. In this book, Nurcan and her coeditors have collected 20 contributions from leading researchers in information systems engineering, pr...

Integration of different components that compose enterprise Information System (IS) represents a big challenge in the IS development. However, it is indispensable in order to avoid fragmentation of the IS and redundancy between different IS applications. In this work we consider service-driven IS engineering as a prospective approach to deal with I...

Changes and extensions of enterprise information systems (IS) often engender their fragmentation and redundancy. In order to overcome these problems, service-driven IS development is considered as a potential solution to support IS evolution when guaranteeing its integrity and consistency.

In this work we apply service-oriented development principles to information systems. W...

Interoperability is a key property of enterprise applications, which is hard to achieve due to the large number of interoperating components and semantic heterogeneity. The inherent complexity of interoperability problems implies that there exists no silver bullet to solve them. Rather, the knowledge about how to solve wicked interoperability probl...

Increasing tendency towards globalisation and outsourcing of software and information systems (IS) development poses a number of challenges and difficulties that companies have to deal with. Quite a few studies have been conducted which have identified a set of problems as well as potential benefits of distributed systems development. In this paper...

In this work we propose a Metamodel of Information System Service (MISS) and introduce a situation-driven approach for ISS integration. This approach is based on situational method engineering principals and is defined as a collection of inter-related method chunks.

Two main candidates for the atomic element to be used in situational method engineering (SME) have been proposed: the "method fragment" and the "method chunk". These are examined here in terms of their conceptual integrity and in terms of how they may be used in method construction. Also, parallels are drawn between the two approaches. Secondly, th...

Several approaches have been proposed to support situational method engineering (SME), each of them providing different techniques and using different basic concepts. In this work, we propose a framework for comparing SME approaches based on a generic SME process model. Three approaches are presented and compared by using this framework.

This paper proposes the structure of a so-called method chunk repository that contains instructions on how to solve interoperability problems between organizations and their information systems. We detail how interoperability problems and their solutions should be tagged in order to match them. The combination of such tagged interoperability proble...

Although the Method Engineering (ME) research community has reached considerable maturity, it has not yet been able to agree on the granularity and definition of the configurable parts of methods. This state of affairs is causing unnecessary confusion, especially with an ever increasing number of people contributing to ME research. There are severa...
