Executive Summary

Investing in quality is imperative. With more than half of all software projects considered failed or challenged and with support costs for defective software running as high as 50% of the total development cost, companies must invest in quality, even if they don't have the resources or the culture for a full quality assurance (QA) initiative. Although having formal QA may reduce ongoing support and maintenance costs for software projects by up to 50%, many companies shy away from it altogether because implementing QA requires more formality and maturity than they currently possess. For these companies, starting with quality control (QC) practices provides short-term value by inserting quality into the software development process. By focusing on high-value areas like creating standard test procedures and reporting, companies can improve their production quality and reduce customer-reported defects while building the foundations for a more formal QA practice later.
