Riskquarry

Replace a single project date with deterministic Monte Carlo percentiles, task-level uncertainty, sensitivity, ownership, and planning evidence.

Focused field tools

Three-Point Estimates

Describe optimistic, most likely, and pessimistic duration from explicit conditions.

Simulation

Sample task distributions repeatedly instead of adding one fragile date.

Percentiles

Choose a confidence level that matches commitment and consequence.

Dependencies

Model sequence, parallel work, handoffs, and external waits honestly.

Correlation

Recognize tasks that move together under the same hidden driver.

Scope

Separate committed work, options, discovery, defects, and contingency.

Riskquarry simulates entered triangular task estimates and does not predict the future. Dependencies, correlation, scope changes, staffing, queues, interruptions, quality, and unknown work can dominate the result. Revisit assumptions with the people doing the work and communicate ranges, not guarantees.
