Additional Items to include:
What makes a good project charter is very much a subjective question and the answer will be defined by your organizations culture, specifically “The way we do things around here”.
Tasks, Task Groups, Work Breakdown Structure
If you can summarize the tasks that need to be accomplished you can include a summary of it on your project charter. In some cases, a few notes about Project Scope may be enough to get the project started.
If you are running a project designed to generate Cost Savings, or New Revenue, identifying that in the project charter can be useful.
You’ll discover more of these as you flesh out your project plan, but this is a good place to acknowledge any top-level risks that you already know about from the outset.
What is it that you actually need to deliver as part of this project?
High-level overview of resources, budget, and people power.
If there are already any pre-approved resources allocated to this project, make a note of them in your project charter so you know what you’re working with.
A top-level summary schedule.
You can delve into the nitty-gritty later, but it’s useful to outline a basic time frame for your project, as well as plot out any key milestones along the way.
Your charter isn’t to go deep on any of the above; you can do that in the project plan. Instead, your aim is to cover enough ground to align all key stakeholders and get everyone onto the same page about the purpose, scope, and breadth of the project, so they can embark on the project with confidence.
