I delivered very large (and lengthy) projects as well as short ones with quick turnaround time in the software services space. While specific projects have specific requirements, such as regulatory and compliance, in general and broadly, your PM should be tracking the following:-

1. Tasks, deliverables

2. Time

3. Cost

4. Issues/Risks
.
For small or micro projects, the above structure should be sufficient. The last one comes into play only if something goes wrong with small or micro projects. A great tool that I use is a requirements traceability matrix. This makes tracking of deliverables and completion status easy and data from this matrix can easily be extracted and plugged into the status report that needs to be sent out to the customer. Time and Cost need not be a part of the client status report; it is more for internal tracking.

Structuring small and micro projects typically to have small teams with each team member being responsible for the entire development life-cycle of a particular feature or requirement (unlike large projects where analysis and design and development and testing are each handled by separate teams) is ideal.

Please reach out for more insight on the above as well as how to manage remote teams etc. (if your team is so structured).
