✅ Correct answer: A plan-driven approach with baselines
📌 Explanation: Regulated, validated scope, fixed-price procurement and a matrix of functional staff all point to a predictive, plan-driven approach, where scope, schedule and cost are baselined up front and changes pass through formal change control.
❌ Why the other options are wrong: Scrum suits evolving requirements and frequent customer feedback, which a validated line does not need; Kanban suits a continuous flow of service work rather than a one-off installation; XP is a software engineering method and its practices do not fit equipment installation.
📋 Objective: 2.1 (Explain when it is appropriate to use a predictive, plan-based approach)
