Given the following statements concerning a test process-improvement activity:
The Deming (PDCA) cycle is a generic, domain-independent improvement model made up of four phases, whereas the IDEAL model is a process-improvement model developed specifically for software and test process improvement and comprises five phases (Initiating, Diagnosing, Establishing, Acting, Learning); this distinction of genericity/phase-count is what the ISTQB Expert Level Improving the Testing Process syllabus uses to differentiate the two models.
