sentences: Soflware Quality Assurance (SQA) organizations are responsible for assuring that defined processes are followed by project teams. The multitude of tasks that are needed to execute a software lifecycle can overwhelm SQA resources making selection of tasks to audit similar to shooting at a moving target, blindfolded. The Mission Operations Directorate In foramtion System (MODI$) Group, an organization within NASA's Johnson Space Center, has developed a statistical method to determine a representative sample size for the number of process tasks to be audited by SQA. This method combines standard statistical sampling techniques with risk analysis to determine and appropriate sampling size. The result is a sample of process tasks which is truly representative ofthe work performed.
