-We have mentioned //issue driven development// a few times.  This is the idea of using an issue management system as a 'to do list' to drive your development.  Issues help you to give your commits more context and make it easier for yourself and other developers to find the code for a particular feature or bug.  Issues also help to form part of the documentation for the system, particularly since developers can add comments to issues to elaborate on decisions or provide clarification for problems and bugs.

Issues also help to form part of the documentation for the system, particularly since developers can add comments to issues to elaborate on decisions or provide clarification for problems and bugs.
 
 Using issues is also a good way of ensuring that your commits make sense --- work on a single issue and then commit before starting on the next issue.  If you do this then your commit history will be focused around your issues, and assuming your issues are based on features, bugs, and other logical work units (which they should be), then your commit history will make sense.
