Solutions focus means

What does the client want?
How is he going to get it?
What are his strengths and resources?
How has he solved similar problems in the past?

Useful answers to these questions are achieved following some simple practical rules like:

Do more of what works!
If it doesn’t work, don’t do it!
Don’t fix anything unbroken!
Change is not only always possible, it is inevitable.
Small steps lead to big changes.
