Question
While developing a schedule of portfolio components for proposal to the governance board, a portfolio manager has identified the following priorities of four components:
The following component dependencies exist:
Component A is dependent on the output of Component B Component B is dependent on the output of Component C Assuming that resource constraints do not allow work to be done on two components in parallel, in which order should the components be listed on the portfolio roadmap?
Options
- AA, D, B, C
- BB, C, D, A
- CD, A, B, C
- DD, C, B, A

Explanation
The dependency chain requires: C must finish before B can start, and B must finish before A can start. This means the mandatory execution sequence for the dependent components is C → B → A. Component D has no stated dependencies, making it eligible to be placed first on the roadmap (and given its stated highest priority ranking among the four components, it should lead). The resulting order is D, C, B, A. Option A (A, D, B, C) violates the dependency chain. Option B (B, C, D, A) would require B before C, which is impossible given the dependency. Option C (D, A, B, C) places A before B and C, again violating dependencies. Only option D (D, C, B, A) satisfies both the priority ranking and all dependency constraints.
