Question 560

A product team says progress is fine but backlog effort is not trending down. Which principle MOST directly explains how the project should be managed?

Control charts distinguish expected process variation from special causes
Burndown charts show remaining scope against time
Velocity reflects historical completed work in a particular team context
Pareto charts rank categories to focus improvement on major contributors

Explanation

Correct Answer

Burndown charts show remaining scope against time. The situation involves a product team says progress is fine but backlog effort is not trending down, so this is the governing distinction.

Incorrect Answers

That principle concerns control chart rather than the problem of burndown chart. Control charts distinguish expected process variation from special causes.

That principle concerns velocity chart rather than the problem of burndown chart. Velocity reflects historical completed work in a particular team context.

That principle concerns pareto chart rather than the problem of burndown chart. Pareto charts rank categories to focus improvement on major contributors.

Question 561

A product team says progress is fine but backlog effort is not trending down. Which caution is MOST directly relevant to the project manager's decision?

An observed point above the mean is not automatically out of control
A rising burndown line does not necessarily mean more work was completed
A decision tree is not proof of outcome certainty when probabilities are estimates
A histogram is not best suited to showing named defect categories by rank

Explanation

Correct Answer

A rising burndown line does not necessarily mean more work was completed. The underlying reason is that burndown charts show remaining scope against time.

Incorrect Answers

This is a caution about control chart, not the immediate risk in burndown chart. Control charts distinguish expected process variation from special causes.

This is a caution about decision tree, not the immediate risk in burndown chart. Decision trees structure sequential choices under uncertainty.

This is a caution about histogram, not the immediate risk in burndown chart. Histograms display frequencies across ranges of numeric values.

Question 562

A sprint has scope additions and the PM needs to distinguish delivered work from scope growth. Which project-management action BEST addresses this situation?

Use a burnup chart showing completed work and total scope as separate lines
Plot paired quantitative observations on a scatter diagram
Model branches, probabilities and outcomes in a decision tree
Use a run chart to display ordered observations over time

Explanation

Correct Answer

Burnup charts make scope growth visible alongside cumulative completion. Here, a sprint has scope additions and the pm needs to distinguish delivered work from scope growth; the chosen action targets that failure. Verification: check the gap between completed effort and current total requirement.

Incorrect Answers

This response addresses scatter plot, but the stated decision concerns burnup chart. Scatter diagrams visualize relationships between two numeric variables.

This response addresses decision tree, but the stated decision concerns burnup chart. Decision trees structure sequential choices under uncertainty.

This response addresses run chart, but the stated decision concerns burnup chart. A run chart shows variation over time without requiring control limits.

Question 563

The team follows this response: Use a burnup chart showing completed work and total scope as separate lines. Context: a sprint has scope additions and the pm needs to distinguish delivered work from scope growth. Which evidence BEST verifies the intended outcome?

Inspect temporal trends and sustained shifts in the measure
Verify each suspected cause is tested with evidence before corrective action
Check whether the dominant categories account for most observed loss
Check the gap between completed effort and current total requirement

Explanation

Correct Answer

Check the gap between completed effort and current total requirement. That evidence tests the response to a sprint has scope additions and the pm needs to distinguish delivered work from scope growth instead of an unrelated project condition.

Incorrect Answers

This check would validate run chart, not the result required by the burnup chart case. A run chart shows variation over time without requiring control limits.

This check would validate fishbone diagram, not the result required by the burnup chart case. Fishbone diagrams organize potential contributors to a defined problem.

This check would validate pareto chart, not the result required by the burnup chart case. Pareto charts rank categories to focus improvement on major contributors.

Question 564

A product manager is confused because completion percentage falls after new work arrives. Which principle MOST directly explains how the project should be managed?

Burnup charts make scope growth visible alongside cumulative completion
Scatter diagrams visualize relationships between two numeric variables
Fishbone diagrams organize potential contributors to a defined problem
Control charts distinguish expected process variation from special causes

Explanation

Correct Answer

Burnup charts make scope growth visible alongside cumulative completion. The situation involves a product manager is confused because completion percentage falls after new work arrives, so this is the governing distinction.

Incorrect Answers

That principle concerns fishbone diagram rather than the problem of burnup chart. Fishbone diagrams organize potential contributors to a defined problem.

That principle concerns control chart rather than the problem of burnup chart. Control charts distinguish expected process variation from special causes.

Question 565

A product manager is confused because completion percentage falls after new work arrives. Which caution is MOST directly relevant to the project manager's decision?

A histogram is not best suited to showing named defect categories by rank
A single remaining-work line cannot distinguish delivery from scope additions as clearly
A decision tree is not proof of outcome certainty when probabilities are estimates
A cause written on the diagram is a hypothesis, not confirmed root cause

Explanation

Correct Answer

A single remaining-work line cannot distinguish delivery from scope additions as clearly. The underlying reason is that burnup charts make scope growth visible alongside cumulative completion.

Incorrect Answers

This is a caution about histogram, not the immediate risk in burnup chart. Histograms display frequencies across ranges of numeric values.

This is a caution about decision tree, not the immediate risk in burnup chart. Decision trees structure sequential choices under uncertainty.

This is a caution about fishbone diagram, not the immediate risk in burnup chart. Fishbone diagrams organize potential contributors to a defined problem.

Question 566

An agile team needs an empirical basis for future sprint capacity. Which project-management action BEST addresses this situation?

Build an Ishikawa cause-and-effect diagram grouping hypotheses
Plot paired quantitative observations on a scatter diagram
Use a burnup chart showing completed work and total scope as separate lines
Track accepted story points per sprint and use stable trend for planning

Explanation

Correct Answer

Velocity reflects historical completed work in a particular team context. Here, an agile team needs an empirical basis for future sprint capacity; the chosen action targets that failure. Verification: review rolling completed points rather than planned points alone.

Incorrect Answers

This response addresses fishbone diagram, but the stated decision concerns velocity chart. Fishbone diagrams organize potential contributors to a defined problem.

This response addresses scatter plot, but the stated decision concerns velocity chart. Scatter diagrams visualize relationships between two numeric variables.

This response addresses burnup chart, but the stated decision concerns velocity chart. Burnup charts make scope growth visible alongside cumulative completion.

Question 567

The team follows this response: Track accepted story points per sprint and use stable trend for planning. Context: an agile team needs an empirical basis for future sprint capacity. Which evidence BEST verifies the intended outcome?

Check the gap between completed effort and current total requirement
Review rolling completed points rather than planned points alone
Inspect values and patterns relative to established statistical control boundaries
Check direction, strength and outliers before inferring association

Explanation

Correct Answer

Review rolling completed points rather than planned points alone. That evidence tests the response to an agile team needs an empirical basis for future sprint capacity instead of an unrelated project condition.

Incorrect Answers

This check would validate burnup chart, not the result required by the velocity chart case. Burnup charts make scope growth visible alongside cumulative completion.

This check would validate control chart, not the result required by the velocity chart case. Control charts distinguish expected process variation from special causes.

This check would validate scatter plot, not the result required by the velocity chart case. Scatter diagrams visualize relationships between two numeric variables.

Question 569

Product owners assume the team can complete 80 points without historical evidence. Which caution is MOST directly relevant to the project manager's decision?

A rising burndown line does not necessarily mean more work was completed
A Pareto chart is not simply any chart showing defects over time
A cause written on the diagram is a hypothesis, not confirmed root cause
One team's velocity cannot be directly compared with another team's output

Explanation

Correct Answer

One team's velocity cannot be directly compared with another team's output. The underlying reason is that velocity reflects historical completed work in a particular team context.

Incorrect Answers

This is a caution about burndown chart, not the immediate risk in velocity chart. Burndown charts show remaining scope against time.

This is a caution about pareto chart, not the immediate risk in velocity chart. Pareto charts rank categories to focus improvement on major contributors.

This is a caution about fishbone diagram, not the immediate risk in velocity chart. Fishbone diagrams organize potential contributors to a defined problem.

Question 570
