I was given a task of presenting management with a dashboard for multiple projects. Please suggest to me a suitable template. What are the main parameters that should be showcased on this dashboard?
There's no possible way for us, strangers on the internet, to be able to know with certainty what information your management needs.
So, ask them. I suggest compiling a list of all possible types of information you could provide them (just the types (e.g. estimated time, actual time, team members, process, etc.), not the data themselves (5 weeks, 3 weeks, 4 members, 7 members, etc.)). Then ask them which information they're interested in seeing on the dashboard.
Although I agree with Sarov, I think that the process should be as follows: you shoud first understand what they want and then create a scope based on your experience and what you think it's valuable.
It's similar to what Henry Ford said: “If I had asked people what they wanted, they would have said faster horses.”
In my experience, having a big overview is always helpful. With Ontime it's possible to create custom views and show: average number of tasks per sprint, milestones to be completed, tasks in the backlog, along with other metrics and plots. This allowed the board to do informed decisions about priorities.
Usually top management want to see such main project parameters like being on time and on budget, and some evidence around that. Especially for Fixed Price projects or similar.
To represent the params you can have a couple of charts similar to Fever Portfolio Chart
but representing both remaining schedule and budget buffer. This is extremely visual.
You dont need to implement Theory Of Constraints for that fully. Just have some estimates and actual spent time for your tickets. Then cut the estimates, say, on 30% and call them "project buffer".
For T&M projects top management is usually interested in following: do we spend all dedicated budget or not? And you can provide some info on how much you have already spent, how much you should have spent on the moment, and forecasting of the things for the end of the contract.
