According to the Agile Practice Guide (Section 4.3.2) and the PMBOK® Guide, adaptive (Agile) environments emphasize focus and the reduction of " work in progress " (WIP) to increase throughput and efficiency.
Why Choice D is correct: Full allocation (or dedicated team members) is the practice of assigning staff to a single project at 100% of their capacity. In an adaptive context, having a dedicated team is a core success factor. It eliminates the " hidden costs " of productivity loss associated with moving between different contexts. Since this is the " company ' s top-ranked project " and the goal is to " increase throughput and provide consistent delivery, " full allocation is the only strategy that ensures the team can achieve a stable Velocity and deliver increments without the delays caused by competing priorities.
Analysis of other options:
A (Task switching): This is the act of shifting focus from one task to another. Research cited in PMI documentation suggests that task switching can cost a person 20% to 40% of their productive time due to the " rebooting " of their mental context. It decreases throughput rather than increasing it.
B (Multitasking): Similar to task switching, multitasking is generally viewed as a " waste " (Muda) in Lean and Agile methodologies. It creates bottlenecks and extends the lead time of all projects involved.
C (Prediction): Prediction refers to the ability to estimate future outcomes based on data. While useful for planning, it is not a method for assigning team members to increase throughput.
By implementing Full Allocation, the Project Manager follows the principle of " Stop Starting, Start Finishing, " allowing the team to focus entirely on the website migration and maximize the value delivered to the organization.
