Are you looking to estimate a task quickly, for example when estimating your product backlog or during a Planning Poker session, without overthinking it or using complex calculations?
There’s a very simple solution for that, it’s called T-shirt sizing estimation.
Instead of using the Fibonacci sequence, hours, or days, you can broadly estimate a task using T-shirt sizes: S, M, L, XL.
No need to overcomplicate things, just pick a value that everyone already understands.
A simple task, like an S, could be adding a button to a page.
A more complex task, like an XL or XXL, could be integrating an API or building an entirely new feature from scratch.
In short, T-shirt sizing estimation is fast, visual, and collaborative, and helps teams estimate work more quickly and more easily.
And you—have you ever tried this method during a Sprint Planning, for example?
