Estimation is a loaded and complicated topic. Whether talking about hours, playing planning poker, or aiming for one of many interpretations of #NoEstimates, you need to understand the role of estimation in your practice. Even if your organization is open to a different conversation about dates, regulatory constraints, markets, and events can impose unavoidable demands for forecasting.

Even if you're comfortable with your current estimation practices, do you know they're effective? Are they the right practice for your situation? Can you improve on them? Do you even know your alternatives?

This workshop will cover a variety of approaches to forecasting and reporting progress based on opinions and empirical data, from story points, t-shirt sizes, or hours, days, weeks, or months to cycle time and probability assessments. We will discuss various techniques for forecasting and for knowing which techniques to use under which circumstances.
