Effectiveness Of Defect Prevention In I.T. For Product Development

TL;DR

This paper emphasizes the importance of defect prevention through inspections at all software development phases, demonstrating that early detection significantly reduces post-deployment defects and overall costs.

Contribution

It provides an analysis showing that 55-65% of defects occur during the design phase and highlights the effectiveness of inspections throughout the development cycle.

Findings

55-65% of defects occur at the design phase

Inspections at all phases reduce post-deployment defects

Early defect detection saves time and resources

Abstract

Defect Prevention is the most critical but most neglected component of the software quality assurance in any project. If applied at all stages of software development, it can reduce the time, cost and resources required to engineer a high quality product. Software inspection has proved to be the most effective and efficient technique enabling defect detection and prevention. Inspections carried at all phases of software life cycle have proved to be most beneficial and value added to the attributes of the software. Work is an analysis based on the data collected for three different projects from a leading product based company. The purpose of the paper is to show that 55% to 65% of total number of defects occurs at design phase. Position of this paper also emphasizes the importance of inspections at all phases of the product development life cycle in order to achieve the minimal post deployment defects.
