Thanks for the comments & feedback so far!
I would say in the end it should be up to every team what tools and processes they end up using. They are responsible for making the relevant data available, operating transparently, and being able to report accordingly.
The DAO Operations Team can suggest best practices and offer guidance but should not have a mandate to intervene in working systems.
I personally believe Notion and Dework are both great tools that help us achieve this but I wouldn’t manifest it in the process.
This is why we should apply using Objectives & Key Results (or similar frameworks) and find ways to better oversee our expenses. Just because things cost a certain price it doesn’t mean we should always pay it.
I agree there can be situations of surprising opportunities or unexpected costs. We could add a paragraph with an option of covering shortcomings with grants and disclosing it in the next Season proposal.
Great points made by both of you so far - very important to cover those aspects. 
Let’s hear some more!
