PERT Calculator: Three-Point Estimation for Jira by Aneto

When a single guess or story points feel too thin, PERT calculator lets you set optimistic, most-likely, and pessimistic hours on a Jira issue and turns them into a weighted expected value.

Use the deviation signal to flag stories and sub-tasks with more schedule risk, then keep planning from the issue view you already use.

Who it is for: project managers, tech leads, and estimators who want three-point estimates in Jira instead of a separate spreadsheet.

What it is not: not a timesheet, not planning poker scoring, and not a full resource planner. Use it when you want PERT-style estimates on work items.
