As a PM who was new to our organization, I started out using Asana for me only, and working out project plan/task structures that matched up with our team’s project plan/spreadsheet/email timelines and activities. I just assigned every task to myself, although I created and named tasks as if they were for other people.
I shadowed our team’s work this way for a few weeks – it really helped me maintain my sanity because there was no real method in use for tracking what people were doing. (Other than of course the dreaded “status” spreadsheet that needed to be updated every day in order to be of any use.)
Once I felt comfortable that I understood the projects, the team members, the workflow, and what level of granularity was appropriate for tasks, I was able to just shift my team into Asana by actually assigning them the tasks I had been creating for them all along.
It took some hand-holding after the switch, but I felt that by having test-driven Asana this way, it gave the team more confidence that I wasn’t imposing something on them that I didn’t know would work.
