The Intertwining of Enterprise Strategy and Requirements.
No full textRequirements Engineering techniques need to focus not only on the target technical system, as has traditionally been the case, but also on the interplay between business and system functionality. Whether a business wishes to exploit advances in technology to achieve new strategic objectives or to organise work in innovative ways, the process of Requirements Engineering could and should present opportunities for modelling and evaluating the potential impact that technology can bring about to the enterprise. This chapter discusses a co-designing process that offers opportunities of change to both the business and its underlying technical systems, in a synergistic manner. In these design situations some of the most challenging projects involve multiple stakeholders from different participating organisations, subcontractors, divisions etc who may have a diversity of expertise, come from different organisational cultures and often have competing goals. Stakeholders are faced with many different alternative future ‘worlds’ each one demanding a possibly different development strategy. There are acute questions about the potential structure of the new business system and how key variables in this structure could impact on the dynamics of the system. This chapter presents a framework which enables the evaluation of requirements through (a) system dynamics modelling, (b) ontology modelling, (c) scenario modelling and (d) rationale modelling. System dynamics modelling is used to define the behaviour of an enterprise system in terms of four perspectives. Ontology modelling is used to formally define invariant components of the physical and social world within the enterprise domain. Scenario modelling is used to identify critical variables and by quantitatively analyzing the effects of these variables through simulation to better understand the dynamic behaviour of the possible future structures. Rationale modelling is used to assist collaborative discussions when considering either ontology models or scenarios for change, developing maps, which chart the assumptions and reasoning behind key decisions during the requirements process

From software engineering to business engineering: ESPRIT projects in information systems engineering (abstract)
No full textInformation systems and enterprise integration
No full textThe aims and objectives of Enterprise Integration is the development of computer-based systems that facilitate the co-ordination of tasks and infonnation ílow across organisational boundaries. Tbis is a key challenging area as increasingly organisations strive for improving thc co•ordioation between systems and ultimately individuals. Thc success of this undertaking depends to a Jarge extent on the ability of information systems to provide the necessary technological baseline for achieving the desired results.
Tbis paper discusses sorne imponant issues undcrpinning enterprise integ-ration which give rise to a set of requirements for improved design paradigms. In particular the different facets of requirements engi.neering and supporting environments for enterprise integration are examined in detail
Experiences with modelling early requirements
No full textA key challenge in the development of systems is the engagement of domain experts in their articulation, agreement, and validation of requirements. This challenge is particularly pronounced at the early requirements phase when multiple stakeholders from different divisions and often different organisations need to reach agreement about the intended systems. Decisions taken at this stage have a profound effect on the technical and economic feasibility of the project. The S3 approach advocates the use of a modelling process expressed in terms of strategy-service-support dimensions, augmented by appropriate simulation techniques that enable experimentation with different scenarios. The S3 approach has been presented elsewhere. The aim of this paper is to provide insights from a large project in which the author played an active and interventionist part, on the utility of the S3 approach in facilitating stakeholder engagement in early requirements specification. The action research for this project involved the design of venue operations for the Athens 2004 Olympic Games. Many tens of stakeholders from a wide spectrum of professional expertise participated in the definition of business support systems for 21 competition venues over a period of 3 years. An interesting feature of this project was the use of three different approaches, starting with traditional peer-to-peer knowledge transfer, followed by a typical business process modelling method and finally adopting the S3 approach and the way of working for the entire design of venue operations. The paper offers insights on all three approaches, insights that reflect on the problem of early requirements in general and on the validation of the effectiveness of the S3 approach in particular. © 2012, IGI Global
