“…The evaluation decisions using these methods tend to be driven by ways that are not connected to, and usually not optimal for value creation. Factors such as flexibility, time to market, cost and risk reduction often have higher impacts on value creation [Boehm and Sullivan, 2000]. Hence, flexibility is in the essence.…”

Using real options to select stable middleware-induced software architectures

The requirements that force decisions towards building distributed system architectures are usually of non-functional nature. Scalability, openness, heterogeneity, and fault-tolerance are examples of such non-functional requirements. The current trend is to build distributed systems with middleware, which provide the application developer with primitives for managing the complexity of distribution, system resources, and for realizing many of the non-functional requirements. As non-functional requirements evolve, the "coupling" between middleware and architecture becomes the focal point for understanding the stability of the distributed software system architecture in the face of change. We hypothesise that the choice of a stable distributed software architecture depends on the choice of the underlying middleware and its flexibility in responding to future changes in non-functional requirements. We devise an option-based model to value such flexibility and guide the selection. We empirically evaluate the model using a case study that adequately represents a medium-size component-based distributed architecture. We report on how a likely future change in scalability could impact the architectural structure of two versions, each induced with a distinct middleware: one with CORBA and the other with J2EE. Our hypothesis is verified to be true for the given change. We conclude with some observations that could stimulate future research in the area of relating requirements to software architectures.

Abstract:The selection, procurement, and deployment of an Enterprise Resource Planning (ERP) system is fraught with risk in exchange for significant business and financial rewards [26]. In many cases the packaged ERP product does not provide the entire solution for the business process. These gaps can be closed with third party products or by customizing existing products. Management of this customization, as well as the selection of the core ERP system has traditionally been addressed through high-ceremony, science-based, project management methods [13]. Well-publicized failures using this approach creates the need for new methods for managing ERP projects [11]. This compendium paper describes an alternative to the traditional high-ceremony IT projects management methods. Although many of the methods described are not new assembling them into a single location and focusing on a single issue provides the tools to make decisions in the presence of uncertainty, focus on the critical success factors, and address the managerial and human side of project management Agility allows the project management methods as well as the system to be adaptively tailored to the business needs.

A theory of software reuse strategies in ideal type stable and turbulent market environments

Increasingly, IS (information systems) need to better support objectives on the overall business strategy level. Software reuse is one promising concept discussed in development organizations in this context, since it is one key issue in designing and delivering IS and software applications. Reuse is a higher-level strategy with its scope reaching from beyond project boundaries to global markets. Consequently, market conditions have to be considered in software reuse management strategies. With the emergence of modern, turbulent market environments that co-exist with traditional, more stable business conditions, this paper investigates these two different, ideal type market environments, their business strategies, and related software reuse options. It investigates supporting experience from three large projects, builds theory, and concludes with two hypotheses on strategic management preferences for software reuse.
