While preparing the project plan, the project manager and BuildyBrick’s planning specialist use the product...

The correct answer is B . PRINCE2 product-based planning determines the logical sequence of work by examining the products to be created and the dependencies between those products . Once those relationships are understood, activities or work packages that do not depend on one another can legitimately be scheduled in parallel.

In this scenario, the project manager and BuildyBrick’s planning specialist use the product flow together with historical information from previous projects. This is appropriate because the product flow provides the dependency logic, while previous project data can improve the realism of estimates and planning decisions. If the utilities and systems products are independent, separate work packages can therefore proceed concurrently.

Option A is incorrect because historical information should inform planning but cannot replace dependency analysis. A schedule should be derived from the logical relationships between products rather than copied mechanically from previous projects. Option C introduces a restriction that PRINCE2 does not impose: products delivered by the same supplier do not automatically need to be produced sequentially. Option D confuses tolerances , which establish delegated performance limits, with dependencies, which determine the logical production sequence.

The scenario is therefore a valid example of using product-based planning to identify opportunities for parallel delivery without compromising dependency logic.
