Several studies have shown that 50–70% of the total lifecycle cost for a software system is
spent on evolving the system. Organizations aim to reduce the cost of these adaptations, by …

Since the architecture of a software system constrains the quality attributes, the decisions
taken during architectural design have a large impact on the resulting system. An …

Several authors have identified that the only feasible way to increase productivity in software
construction is to reuse existing software. To achieve this, component-based software …

Background: Action research is a well-established research methodology. It is following a
post-positivist research philosophy grounded in critical thinking. The methodology is driven …

We have recently seen a renewal of interest in the field of software architectures. This has
happened within the object-oriented community-with the emergenceofframe works and …

Object‐oriented frameworks provide software developers with the means to build an
infrastructure for their applications. Unfortunately, frameworks do not always deliver on their …

In general, professionals still ignore scientific evidence in place of expert opinions in most of
their decision making. For this reason, it is still common to see the adoption of new software …

In the previous chapter, a first version of some software architectures, based on the
functional requirements, was designed. In order to decide whether these architecture fulfil …

Over the last decade, several authors have studied the maintainability of software
architectures. In particular, the assessment of maintainability has received attention …

Several studies have shown that 50% to 70% of the total lifecycle cost for a software system
is spent on evolving the system. Since incorporating anticipated changes generally requires …
