Quantitative management
Quantitative management defines specific KPIs — quality metrics — which are measured to ensure that QA procedures and quality-related processes flow as planned. Quantitative management is used as a base for operational management and strategic decisions regarding the quality of a software project.
Quality metrics are collected for a certain time frame to define the baseline for each indicator. The most important cases to look at are those, which significantly differ from the expected or planned level. Impulsive changes (whether up or down) of some indicators may signal something going wrong. After the analysis phase, we develop a plan to influence some or all indicators, improving the process and resources involved. When the plan is ready, it is implemented and tracked again to confirm that the measures are effective and sufficient.
