From Gut Feel to Data-Driven Confidence: Introducing the Estimation, Measurement & Forecasting Series
Most teams treat estimation like a guessing game. They cycle through a round of “how long will it take?” that ends in shaky promises. High-performing teams know something different: estimation and forecasting aren’t the same thing, and they’re not mutually exclusive. They’re connected by something critical in between: measurement.
- Estimation is a sense-making exercise. It helps the team explore the work, surface uncertainty, clarify risk and make assumptions explicit.
- Measurement is the reality check. It captures how your system actually performs: how fast work moves, where the bottlenecks are, and how steady your rhythm is.
- Probabalistic forecasting is a decision-making tool. It uses real delivery data (throughput, cycle time, variability) to model likely outcomes and confidence ranges.
When you combine all three, you stop chasing precision and start building confidence. In our work at Ally, we help product and engineering teams create a rhythm where they learn through estimation, measure through data, and plan through probabilities.
This series will take you on a journey of Learn, Measure, and Plan.
