Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Project Management
Project Duration Estimator (PERT)
Estimate realistic task or project durations using the PERT three-point technique, which blends optimistic, most-likely, and pessimistic scenarios into a single weighted average. Use it whenever a single-point estimate feels too uncertain.

Project Management
Project Quality Score Calculator
Compute a composite quality score for a project by combining test pass rate with a penalty for critical defects found. Use this at the end of a testing cycle or release gate to decide whether the build is fit for deployment.
