Maintenance of a computer-based system accounts for a large proportion of the total system cost. However, no well-established techniques exist for assessing the maintainability of such a system. This paper presents a case study in assessing the maintainability of a large, software intensive system. The techniques we used are described, and their strengths and weaknesses discussed.

We introduce general methodologies for benchmarking the availability and maintainability of computer systems. Our methodologies are based on fault injection, used to purposefully compromise availability and to bring systems to a state where maintenance is required. Our availability benchmarks leverage existing performance benchmarks for workload generation and data collection, measure availabil...

Abstract The post-construction phase represents a critical milestone in the project lifecycle. This is because design errors and omissions as well construction defects are examined during this phase. traditional procurement approaches that commonly adopted projects separate from construction, which inhibits contractors, suppliers other parties providing team with constructive comments feedback ...
