The Product Delivery Triangle

1. Agility

The teams’ ability to react to changes in requirements, development time issues and organizational pivots. You can also consider this as reactiveness to change.

2. Predictability

This accounts for commitments made v/s what is actually delivered at a fixed point in time. If the team commits to delivery N number of items in the to-do list in X days, predictability is how close to N the team reaches on an average.

It is of course impossible in real world scenarios to delivery N items as was committed since engineering complexities, process dependancies and people factors come into play. There is also the matter of our inability to estimate the size of the work to be done.

3. Efficiency

Efficiency looks at how many work packets or items were delivered by the team v/s how much they could have delivered. It is obviously hard to say how much they could have delivered, but you can look at it as a relative (across methods) area.

A perfectly efficient team utilizes all their time in delivering items. This is of course impossible as the same factors that plague predictability plague this area too.
