With the motto of “doing it right first time”, this study focuses on spearheading integration designers, constructors, and facility mangers, at outset planning/design stage, by providing easy-to-read tables summarising (1) knowledge learnt from past mistakes (2) maintainability benchmarks, to ensure high for Basements Wet Areas. The commonly occurring problems in Areas a total 110 buildings com...

With the arrival of large real-time, time-shared systems, the requirement of system reliability has become even more demanding. The result of even a momentary system misbehavior could be catastrophic, since any disruption of service is experienced by all the users on-line at that time. Thus for real-time systems such as telephone switching systems, airline reservation systems, on-line teaching ...

We have examined 365 versions of Linux. For every version, we counted the number of instances of common (global) coupling between each of the 17 kernel modules and all the other modules in that version of Linux. We found that the number of instances of common coupling grows exponentially with version number. This result is significant at the 99.99% level, and no additional variables are needed ...

The recording and management of design rationales and design decisions are important issues in achieving better support for software maintenance. In the c ontext of existing work on design rationale models, this paper intr oduc es an appr oach to the integration of system design, design decisions and design rationales and the formalisation of design decisions in terms of software artifacts and ...

The paper introduces a new object-oriented metric to evaluate maintainability of the software system at the design stage. Unlike well known object-oriented metrics applicable only to one class or to a category of several interconnected classes the proposed one evaluates the degree of extensibility for the whole static design. The metric is based on the main principles of objectoriented design a...
