When you're working out your planning project, it's very reasonable to get a bit nervous. After all, this thing is costing a fair amount of money, and your neck might feel on the line: I get it.
However, more than once I have seen a customer's response be: "Well, then it better be perfect when I show anybody." And I will tell you that is 100% the wrong answer, for multiple reasons.
First, nothing is ever perfect. You're actually setting yourself up to be disappointed if you are looking for perfection. Things will be much better, but even when you feel "finished", there'll probably be one or two things that you still want to improve. So don't set yourself and your team up for disappointment by expecting and/or promising the ultimate everything.
We're demanding creatures - those few bits that you want to improve, you will improve, but then the organisation will change, or something else will change, and you'll realise there's another thing you need. That's life, so best to start by thinking of this project as a continually evolving and improving beast.
Second, and perhaps more important, looking for perfection will get in the way of the best tool for project success: getting wins as quickly as possible. What you need to be doing is prioritising getting live project phases that will quickly show results. Very often, that's reporting, typically a massive timesink before a planning project and a few clicks afterwards.
Why? Well, showing success takes the edge off for everyone; everyone releases the breath they didn't realise they'd been holding since they signed the contract, and can focus better on next steps. And those next steps become easier because you've freed up time by going live with something that gives time back to you.
And finally, you can't read everyone's mind. The sooner you get something in front of the organisation, the sooner they can tell you what you got wrong about it - so you can course correct early and waste less time building the wrong things.
Get things out there sooner rather than later - you can always improve them.
