That's a very good point - and despite my earlier comment just knowing where and how much the pain points are matters.

For example in the (UK) building trade there is a booming trade in "builder remediation" - fixing the accidental below spec work they did not notice. It can wipe out much of the profit a builder makes having to go in and pull a wall down.

I keep calling the solution to this as "bringing the factory to the field". That is measurements and control processes we see in the factory applied in less controlled environments. With mobile tech for example one could slap QR stickers on timbers, fittings and hard boards and at each stage of the build require a photo of the materials in-situ before they get covered in plaster or the next layer up.

This would help track an enormous number of issues in the building trade.

I can see how just a little inside knowledge can help.
