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

Context switching | Glossary

Definition:

Context switch in computing language is a process of storing the state of a process or of a thread, so that it can be restored and execution of the process is resumed from the same point later.

Multi-tasking requires context switching which does not give productivity gains. There is an increase in the level of frustration for people involved in working on these tasks developers and delivery manager waiting for the tasks to be completed. The greater the level of context switching, the greater the loss in productivity.

Cost of switching context is a form of waste, this waste can be minimised by minimising the number of times a developer switches context.
