Project Time Estimation Calculator
Generate realistic software project timelines by factoring in Brooks's law, team velocity, and dynamic uncertainty buffers.
Frequently Asked Questions
Why does adding more developers decrease efficiency?
According to Brooks's law, 'adding human resources to a late software project makes it later.' Our algorithm mathematically discounts the efficiency of each additional team member due to unavoidable communication overhead and integration complexity.
Why should the buffer increase with complexity?
Complexity does not scale linearly. A complexity 8 task is not twice as hard as an 4 task; it likely contains exponential edge cases. The uncertainty buffer protects you against 'unknown unknowns' during system integration.
Why Your Software Estimates are Always Wrong
Engineers estimate based on 'happy path' thinking. They imagine typing the code perfectly on a Tuesday morning without interruptions. They forget code reviews, CI/CD pipeline failures, and changing client requirements.
The Contingency Architecture
Professional project management requires explicitly buffering for the unknown. When you provide a delivery date, you must provide a mathematical confidence rating attached to that date (e.g., 'We are 85% confident in an 8-week delivery').
