<p>Do you all add revision fixed to your custom fields?</p>

<p>And what is the point of have <code>Work Start</code>? I thought <code>resolve issue</code> is good enough?</p>

We use revision fixed. Makes producing change logs etc much easier.
Never used the work tracking at all. Always just seems like too much hassle, and the teams we've been on we haven't needed to track it that closely. It's different than resolving an issue - that just marks that something is complete. Work start tracks how much time was spent, and if someone is still looking at it.
