The correct selection is D. A burndown chart that repeatedly finishes with incomplete sprint work is direct evidence that the team is forecasting more than it can deliver. It provides an empirical record of missed commitments rather than relying on subjective management impressions. From a planning perspective, the architect must reduce uncertainty before execution by defining ownership, governance, environment purpose, prioritization, and measurable acceptance criteria. Decisions should be repeatable and visible across teams so delivery capacity, risk, and stakeholder expectations remain aligned throughout the lifecycle. The rejected options do not resolve the planning problem at its source; they either add process overhead or make assumptions that leave ownership and delivery risk unclear. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (D. A burndown chart showing the team misses their forecast sprint after sprint). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.
