Some people, generally do some things faster than others and vice-versa.
You can estimate all you want and task it out all you want, but at the end of the day, that’s what it comes down.
Velocity, when defined, is the speed of something moving in a given direction.
The faster someone goes is the easiest (and generally most obvious) way to measure velocity.
But it’s not the only way…
- accuracy
- redundancy
- readability
- transition
- understanding
- reduced bug count
These are all factors that can shape your velocity and show that what you are shipping is more than simply code before X date.
The problem is we can’t define it for you, and we can’t sell it for you – that’s up to you.
