How do I determine the “key assumptions” of a startup

[arunnanda]

I understand the meaning and significance of testing the key assumptions,

In order for the idea to be viable, the key assumptions must hold true. These key assumptions need to be validated in initial user research (in my own words).

But I am somewhat at a loss in listing out what the key assumptions actually are. For me it is just the solution to a problem that annoys me.

Any tips or links to useful resources will be much appreciated.

Even at the level of "make a startup to solve a problem", there are assumptions:

* other people have the problem

* the problem is worth paying money to fix

* the problem is actually solved by the offered solution

* the solution can be operated at a profit

Yes and in a 3 sided platform these assumptions are multiplied more than 3x. But thanks, this is a very helpful starting point.
