PERT Calculator: Three-Point Estimation for Jira by Aneto

Three-point (PERT) estimation inside Jira, so estimates stop living in a side spreadsheet.

• On the work item: a PERT Estimation panel on the issue view opens the calculator in one click.
• Three estimates: enter optimistic, most likely, and pessimistic time in Jira format, such as 4h or 2d.
• PERT estimate and deviation: get a weighted estimate plus its deviation, so risky stories and sub-tasks stand out before the team commits.
• Original estimate: the PERT result is written to the work item's Original estimate field.
• Context: add a comment to justify the numbers and see who entered the estimate.

For project managers, tech leads, and estimators. Not a timesheet, planning poker, or resource planner.
