Junior developers have a hard time to answer the question whether something is done. They need DoD-y!
It contains two elements they have not a lot of experience with: estimating the remaining time to complete (ETC) and knowing when something is completed according to the company’s standards.
Both will come with time and often they are not experienced enough to understand all aspects of the work yet. Scrum solves this by requesting the team to create a Definition of Done (DoD).
Below an example of what this could look like;
A DoD focusses on task decomposition. “How to eat elephant” … “bit by bit”!
If you get an understanding on what to do, the estimation of the time needed will become easier as well.
