prolly

The relationship between a software supplier and its customer is usually an unhappy one founded on unrealistic expectations and characterised by blame and fear. Prolly's goal is to turn it into one characterised by transparency and objectivity.

A software project's design and timescales will always change during implementation. Business culture cannot accept this because it stops investors from calculating a ROI, so contracts will continue to be signed based on a fantasy. To prevent this from poisoning the relationship when reality knocks we need:
1) to remember the underlying motivation of the project and use it to steer change,
2) to predict the rate of progress using correct statistical techniques and issue continuous updates of those estimates.
The prolly tool is intended to be used by the customer as well as the supplier. This makes them feel empowered but makes them work within the same constraints that the supplier is facing.
