Fundamentals of Forecasting
Predicting accurate completion dates using NoEstimates
NoEstimates is a lightweight approach to planning and delivering work that applies Agile thinking to help teams improve deadline performance, focus on value, and reduce budget risk. It helps you answer questions about when products will be finished or how to forecast completion dates with less effort and more accuracy.
If you’re keen to know how to spend less time estimating and more time delivering working software—while providing your customers with some understanding of predictability—expert Matthew Philip helps you understand what factors influence delivery time and by how much. Join in to learn how to move from upfront, intuition-based estimates to a data-based probabilistic forecast that provides a more reliable way to talk about when you’ll be done—and expend less effort to do so. You’ll learn to predict when things will be done with less effort and more accuracy.
What you'll learn-and how you can apply it
By the end of this live, hands-on, online course, you’ll understand:
- The basics of NoEstimates and how it helps improve delivery
- How to reduce variation that affects and creates risk in delivery
- The difference between deterministic and probabilistic forecasts
And you’ll be able to:
- Create a probabilistic forecast that provides a less risky way to plan
- Experiment to determine what factors influence delivery time
- Start simply by collecting data
This training course is for you because...
- You’re a software developer who wants to better estimate when projects will be done and spend more of your time developing.
- You’re a software team manager or leader who needs to inform stakeholders when projects will be completed with accuracy and predictability.
- A working knowledge of traditional estimating approaches
- Familiarity with spreadsheets such as Excel and Google Sheets
