PERT effort estimation calculates expected time and standard deviation from Optimistic, Most Likely, and Pessimistic values. You provide O/M/P inputs for each work package to generate the expected effort, sigma, and confidence intervals for project planning.

Calculating confidence intervals for sprint estimation requires deriving the expected value and standard deviation from your work packages. This Skill computes E and sigma from your structured inputs to provide reliable risk assessment ranges for sprint planning.

T-shirt sizing can be used for project cost forecasting by mapping sizes to structured work packages. This Skill processes T-shirt sizing inputs alongside PERT and Function Point Analysis to output total effort estimates and risk assessments for internal planning and external quoting.

Preparing structured input data for Function Point Analysis involves listing your requirements as work packages in a JSON format. The command-line calculator accepts JSON inputs specifying the fpa method to compute reliable software effort estimates and confidence intervals.

This effort estimation method works directly with Work Breakdown Structure items by calculating O/M/P values for each WBS task. It aggregates these structured inputs to provide total project effort, standard deviation, and confidence intervals for accurate project planning.
