Plan Visualizer Tool: Agile Forecasting for Accurate Plans

The Plan Visualizer tool in the Agile Mentors Community aids in forecasting agile plans' likelihood of completion within target iterations.
By inputting velocity estimates, such as a range of 26–34 for 240 story points in 8 iterations, teams can assess feasibility.
Using the tool, stakeholders can understand work feasibility based on velocity estimates falling within achievable ranges.
If forecasts indicate work may not be completed, options include extending sprints, reducing scope, or a combination of both.
Collaboration with stakeholders to set realistic expectations is facilitated through the Plan Visualizer tool.
Forecasting velocity accurately involves considering historical data, mean velocity, and using a range for future predictions.
Prediction intervals in the tool calculate future velocity ranges using statistical methods for increased planning accuracy.
The Plan Visualizer supports scenario testing by adjusting sprint counts and scope to find viable solutions.
Accessing the Agile Mentors Community provides tools, resources, and a network of agile professionals for enhanced planning capabilities.
Joining the community offers collaborative opportunities, access to tools like Planning Poker®, and a library of agile resources.
