What is the role of Quantitative Project Management (QPM) in Level 3?

• A. QPM uses statistical methods to understand and control the project performance and to predict outcomes.
• B. QPM manages requirements and change control.
• C. QPM handles quality audits only.
• D. QPM defines the software architecture.

Answer: (A)

Quantitative Project Management is about applying statistical and quantitative techniques to understand, control, and predict a project’s performance. In Level 3, where processes are defined and used across projects, QPM provides objective, data-driven insight into how the project is progressing and where it may end up. By collecting performance data on cost, schedule, scope, and quality, and applying statistical methods, the team can understand variability, forecast outcomes, and set realistic thresholds and baselines. This enables proactive decisions to keep the project on track, such as adjusting resources or scope when forecasts indicate risk of overruns. It differs from activities focused on requirements and change control, quality audits, or architectural design, which address other aspects of the project lifecycle.
