Why people use Estimation Prover
Estimation Prover for Accurate Software Project Planning
Estimation Prover changes the starting point. Instead of a single date, it forces a conversation about the work itself. You get a decomposed list of tasks, a map of technical risks, and a buffer based on real historical data. You stop guessing and start planning with evidence.
What Vinkius changes
You get a defensible, data-driven project timeline instead of a guess.

Before you connect
Questions about Estimation Prover.
The practical details behind the request, access and result.
How does Estimation Prover help with project deadlines?
It forces a rigorous breakdown of your project into small tasks. By identifying risks and historical data early, it helps you set realistic dates that you can actually hit.
Can Estimation Prover help me stop overpromising to stakeholders?
Yes. It provides a data-backed reason for your timelines. Instead of a guess, you can show a breakdown of scope, risks, and buffers to justify your dates.
What is the Planning Fallacy and how does this Connector fix it?
The Planning Fallacy is the human tendency to underestimate project time. This Connector fixes it by requiring evidence, like historical precedents and risk mapping, before a date is set.
Does Estimation Prover work for non-software projects?
While it is optimized for software development, it can be used for any project with complex dependencies, risks, and a need for granular scope decomposition.
How does this capability handle hidden technical risks?
It prompts you to explicitly name and rank risks like API reliability or knowledge gaps. This ensures they are accounted for in your final buffer rather than being surprises later.
Can I use Estimation Prover to break down large milestones?
That is exactly what it is designed for. It forces you to decompose large, vague milestones into discrete units of work that are usually two days or less.
How does Estimation Prover validate an estimate?
It analyzes the inputs based on a 5-pivot validation. You provide the task decomposition, risk mapping, historical context, buffer metrics, and assumptions. It rejects single-line guesses or projects without buffers.
What is the recommended buffer size?
The capability enforces a minimum 20% buffer on projects with clear precedents, and increases to 40% or more for complex integrations, new frameworks, or systems with high architectural risk.
How does Reference Class Forecasting work here?
It forces you to compare the new project with similar work completed in the past. If your past authentication integration took 3 weeks instead of the planned 1 week, you must adjust the new estimate's baseline accordingly.
