Which statement correctly describes the intent of Maturity Level 4 with respect to predefined PAs?

• A. The intent of all predefined PAs up to and including Level 3 practices is achieved at Practice Group 3
• B. The intent of all predefined PAs up to and including Level 4 practices is achieved at Practice Group 4
• C. The intent of all predefined PAs up to and including Level 5 practices is achieved at Practice Group 5
• D. The intent of all predefined PAs up to and including Level 2 practices is achieved at Practice Group 2

Answer: (B)

At Maturity Level 4 the focus is on managing processes quantitatively across the predefined Process Areas up to that level. This means you collect and analyze quantitative performance data, use statistical methods to understand and control process variation, and ensure predictable performance across those PAs. Level 4 builds on the foundations of Level 2 (managed) and Level 3 (defined), so the set of PAs involved includes those from Levels 2 through 4. The grouping used to assess this is Practice Group 4, which targets the achievement of all predefined PAs up to Level 4. Therefore, the intent is that all predefined PAs up to and including Level 4 practices are in place and under quantitative management. The other options would refer to different levels or scope that don’t align with Level 4’s focus.
