SAFe-Agilist Product Development Flow Practice Question
A SAFe Release Train Engineer (RTE) is examining the Cumulative Flow Diagram (CFD) for an Agile Release Train. The diagram shows a widening band for the 'In Progress' column over the past three Program Increments, while the 'Done' band remains relatively flat. What does this pattern most likely indicate about the ART's product development flow?
⚠ Common exam trap
The trap here is misreading the CFD as showing increased throughput when the flat 'Done' band contradicts that interpretation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The ART is experiencing a growing queue of work in progress, likely due to a bottleneck or excessive WIP.
A widening 'In Progress' band on a CFD indicates that work is entering the system faster than it is being completed, causing WIP to grow. This often points to a bottleneck or excessive WIP limits, which increases lead time and reduces flow. The ART should address the constraint and limit WIP to restore balance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The ART has too little work in progress and is underutilized.
Why it's wrong here
A widening 'In Progress' band actually indicates an excess of work in progress, not a lack. Underutilization would show a narrow 'In Progress' band and possibly idle capacity. The pattern described points to overloading the system, which increases lead time and reduces predictability. SAFe recommends limiting WIP to improve flow.
- ✗
The ART has achieved a steady state of flow with balanced arrival and departure rates.
Why it's wrong here
A steady state would show parallel bands with consistent width, indicating that arrival and departure rates are balanced. The described pattern of a widening 'In Progress' band and flat 'Done' band indicates an imbalance, with arrivals exceeding departures. This is not a steady state but a system accumulating work and likely increasing lead time.
- ✓
The ART is experiencing a growing queue of work in progress, likely due to a bottleneck or excessive WIP.
Why this is correct
The widening 'In Progress' band with a flat 'Done' band is a classic sign of accumulating WIP. This often results from starting more work than can be finished, leading to longer cycle times and reduced flow. The ART should identify the bottleneck, reduce WIP limits, and focus on completing work before starting new items to restore flow.
- ✗
The ART is increasing its throughput and delivering more value.
Why it's wrong here
A widening 'In Progress' band with a flat 'Done' band indicates that work is entering the system faster than it is being completed, not that throughput is increasing. If throughput were increasing, the 'Done' band would also widen. This pattern suggests accumulating work in progress and potential bottlenecks, which is detrimental to flow.
