# TOSCA

**What is it for?**

Stating a problem. This framework aims to help defining a set of assumptions when framing a problem and is a solid base for hypothesis testing.

**T is for Trouble:**What is the problem your idea attends to solve?**O for Owner:**Whose problem is this?**S is for Success:**What will success look like, and when?**C is for Constraints:**What are the limits on the solution space?**A is for Actors:**Who has a say in the way we solve this problem, and what do they want?

**How do I use it?**

- As a workshop probe in early stage entrepreneurship projects
- As an alignment tool in multi-stakeholders discussions
- As a consulting tool

**Where is it coming from?**

I’ve initially found it in the book: * Cracked it!: How to solve big problems and sell solutions like top strategy consultants *by Bernard Garrette, Corey Phelps, and Olivier Sibony. In the book, authors mention the TOSCA Puccini Opera masterpiece as a source inspiration. But I don’t know if they are the inventors of it.
