Tickets should be stored at the location where these are used or matter. It should be easy to figure out which tickets apply to a certain portion of a project. If a person is working on a part of the project in question, relevant tickets should be available with little work.

Tickets can be stored as a comment at the relevant source code location. Every task should start withTODO, which is recognized by many tools. Additional tags can be used in order to signal, which tasks may be ignored under special conditions or may require special care:

1. ACTIVE: Someone is already working on the marked tag.
2. TOFIX: This task points to an error.
3. IDEA: This task may not be a good idea.
4. HACK: This task marks a code quality issue.
