Take the Guesswork out of Agile Estimation

 

Accurately estimating tasks and projects in an agile workflow is crucial if your team is going to stay productive and your stakeholders are going to stay happy.

Coming up with clear estimates using established methods helps prevent nasty surprises and a lot of wild guessing.

Here at Parabol, we've built our agile estimation templates around some of the most popular estimation methods and the most common sizing scales. But you can also BYOM (bring your own methods) and make your own template to suit your workflow. 

These approaches to estimation help teams build a common language, and in time can reduce the cognitive clutter and missed expectations of improperly sized projects. 

But before you start sizing things up, you’ll need to pick a method…
