PLAYGROUND / LAB

I have no problem with problems. They usually have solutions.

No roadmap. No business case. Just things I wanted to build, break, test and make work. And I still haven't found much use for the word "NO".

LET'S BE CLEARProblemshave a problem with me.I usually solve them.

Plan A usually works. When it doesn't, there are 25 more letters in the alphabet. And SQL.

THE YES LAB

There is always another way.

Four tiny experiments about problems, solutions, enterprise complexity and one suspiciously unavailable word.

NO-FREE ZONE
01CAN RADOVAN FIX IT?

Give me a problem.

It can be technical. It can be weird. The route may change. The answer usually doesn't.

02THE NO BUTTON

Can it be done?

There are technically two options. One of them is considerably more cooperative.

Choose wisely.
03PROBLEM → SOLUTION

Turn a problem into a solution.

The path is rarely elegant. That's fine. Working beats elegant.

How complicated should this be?

Move carefully. A five-minute task is only a few approvals away from becoming a programme.
