# The problem solution context

You want to use design thinking, innovative ways of doing business? You want to use Six Sigma. Which consultants to bring in? How will you answer the question?

It depends on what the situation is. You can have three kinds of contexts depending on your knowledge of the problem and solution.

- Problem: Known / Solution: Known (Known Knowns)
- Problem: Known / Solution: Unknown (Known Unknowns)
- Problem: Unknown / Solution: Unknown (Unknowns Unknowns)

When something is known, you need a linear process and when it is unknown you need a adaptive or dynamic process.

Understanding the situation is key to the kind of process you would use to solve it.
