Cumulative Flow Diagram

5 minutes 5 Questions

A cumulative flow diagram (CFD) is a visual representation of the flow of work within a project over time. It is used in Agile project management to track the progress and status of tasks throughout the various stages of the development process. The diagram is composed of colored bands that represe…

Question 1

You are a project manager working on an Agile project and you notice that the Cumulative Flow Diagram (CFD) has become bottlenecked in the 'Development' phase. What should you do to resolve this issue?

Add more tasks to the backlog without addressing the bottleneck. Ignore the bottleneck and continue working on other tasks. Blame the development team for the bottleneck and demand an immediate solution. Increase the workload for the development team without investigating the bottleneck. Extend the project timeline and keep the bottleneck as is. Identify the cause of the bottleneck and implement measures to alleviate it.

Correct Answer: Identify the cause of the bottleneck and implement measures to alleviate it.

Identifying the cause of the bottleneck, and implementing measures to alleviate the bottleneck helps improve the efficiency of the project workflow and prevents the bottleneck from becoming a major issue in the long-term.

Question 2

In an Agile project, you notice a steady decrease in the width of the 'In Progress' section of the Cumulative Flow Diagram. What can be inferred from this observation?

The throughput of the 'In Progress' section is decreasing. The throughput of the 'In Progress' section is increasing. The project team is not following Agile principles. The project will be delayed. The project is facing a severe bottleneck. The project is running out of resources.

Correct Answer: The throughput of the 'In Progress' section is increasing.

A decrease in the width of the 'In Progress' section of the CFD indicates that the throughput (number of tasks completed per unit of time) is increasing, which is a positive sign for the project.

Question 3

You are analysing a Cumulative Flow Diagram (CFD) on your Agile project, the 'In Progress' section has been steady from the start and not moving upwards. What should you infer from this?

No new items are currently in process. The team is facing a performance issue. The project backlog items are high in number. The team is over-performing.

Correct Answer: No new items are currently in process.

The Cumulative Flow Diagram (CFD) in an Agile project tracks and visualizes the amount of work in different states. The 'In Progress' section showing no upward movement suggests that no new items are currently being processed. If the team was facing a performance issue or over-performing, you would expect to see fluctuations in the 'In Progress' area. A high number of project backlog items would only affect the 'In Progress' area if they were being actively worked on, which does not seem to be the case in this situation. Therefore, the most accurate answer is 'No new items are currently in process.'
