Best way to plan an ERP (fields, buttons, relations) before development?

Hi everyone,
I’m planning to build multiple ERPs (Hospital ERP, Tailor Shop ERP, etc.) and want to know the easiest and most effective way to plan everything BEFORE developing.

I want to plan:

  • All fields & field types

  • Buttons & actions

  • Workflows

  • Relations between modules

  • Permissions

  • UI layout ideas

  • Complete data model

Basically I want to prepare a full blueprint so actual development in Frappe becomes easy, consistent, and reusable for future SaaS products.

Questions:

  1. What tools do you use to plan an ERP before creating DocTypes?

  2. Is there a recommended workflow for planning fields + connections?

  3. Any templates or examples for planning a full ERP?

My goal is to clearly define everything (Patient fields, Consultation fields, Measurement fields for tailor shops, etc.) before creating the DocTypes.

Thanks!

Are you serious?

Anyways, to answer your question, the best way to plan a Frappe app is to think about
