Happiness Metric | Glossary

Definition:

The Retrospective meeting is the “Check” part of Plan-Do-Check-Act cycle where key is getting to that “Act” step, that kaizen which will actually change the process and make it things better the next time. It’s not good enough to share how you feel, you need to be able to act. The best way is to capture all this with what is called “Happiness Matric” which is a very effective way of getting at what the kaizen should be, and also which kaizen will make the people the happiest.

Each person on the team answers few questions on a scale of 1 to 5, about how they feel about their role in the company, how they feel about the company as a whole, why do they feel that way, what one thing will make them happy in upcoming sprint? With these questions in a few minutes every person on the team sparks an insightful conversations. This method exposes what is most important for each team member and what they think is most important for the company.

Happiness Metric is a leading indicator which helps in visualizing the aspects that matters most to the team

Cone of Uncertainty | Glossary

Definition: 

The Cone of Uncertainty is a graphic representation of the increasing accuracy for estimates as the details of the project are known over time. Managers or any stakeholders us this to guide estimates and manage expectations. It describes the evolution of the amount of uncertainty during a project which not only decreases over time, but diminishes its impact by risk management and helps in decision making.

At the beginning of the project little is know about the product so estimates are subjected to large uncertainty somewhere around 4 times the actual time taken. As more research and development begins more information is learnt about the product, development team get more clarity, impediments surfaces which helps in knowing the unknowns where estimates fall more into line with reality.
