When you use story point estimation, you need reference stories to compare one work to other. Why? Because, these story points estimates are unit less. You get story points for a work by comparing the size of those user stories with reference stories.

If you are using Fibonacci series as as scale to estimate, you need reference story for each Fibonacci number. We recommend not to use a single story as a reference for each size. It is like single Gold standard for each size. team needs more stories as reference for each size. It improves understanding the size of work. Using multiple user stories as reference for each size is known as triangulation

Thanks a lot Seema.

So is it like relative sizing. Pick a story that needs half day to code and half day to test and call it 1. All other stories can be estimated relative to this?

Not clear, why multiple stories required?

When you size, you dont think in a way like how much time it will take in coding and how much in testing. for more details, please refer following video:


Multiple stories helps the team to understand the size to compare well.
