Quality enhancement by implementation of depth of inspection metric and inspection performance metric in software industry

Engineering quality software depends much on the control of the defects which in turn involves inhibiting the natural injection of defects and preventing the propagation of defects from its origination. Inspection is an effective process to realise the aforementioned objectives. Hence, inspection has been a focal point of studies and several innovative approaches have been brought out to enhance the quality of software through better inspection. The introduction of two quality metrics namely depth of inspection (DI), which is a process metric, and inspection performance metric (IPM), which is a people metric, enable the quality professional to have quantitative estimation of inspection process and people process. This paper aims to present the modes of practical implementation of the two metrics in software houses to facilitate the production of quality software product. Implementation of the pair metrics reflects continual process improvement and endurance of the company in the competitive environment.
