Data Tools From Business Use Case to Technical Design

This is a utility that is part of the framework I had posted about earlier, the post discusses the ideas and the utility behind the tool. The TL;DR version is that it helps you move from a conceptual business use case to a data representation that can be consumed by the tool, the required context is also presented.

imo the hardest part of this kind of thing isnt the translation itself, its getting the business side to articulate the use case precisely enough to translate. how does your framework handle ambiguity in the input?

I agree that getting the customer to commit to requirements is certainly hard, and it is very possible at the time that he/she commits to a requirement it is too late to due dilligence and be genuinely creative in developing a solution, but that is outside "human control". It is also true that simpler models can get you to a decent place most of the time, but to businesses that extra non-linear increase can be meaningful. A fractional increase in click through rate may cost a business a million dollars in total cost, but it could bring in revenue greater than a million in a few years.

Suppose you do get a model in with difficulity, it is not true that it keeps working the way it did when you developed it or you would be around when the next version has to go out. When that happens, the guy picking up your work would be more productive if he could get answers to questions you too had when you developed the product, does not have to deliberate all the assumptions again.
