Writing perfect software

Optimizing software development processes.

... is not a question of choosing the correct management model, e.g. "top - down hierarchy" vs. "circle of equals".

The problem is a different one and pretty simple to formulate:

Imagine a car assembly line with 200 workers and everybody only doing his work at 98% correct. The final product then is just (0.98)^200 = 0.01758795 correct. Means - 98% pure waste!

Luckily that process can be reversed. Imagine an assembly line, where the next following worker has order to control the work of his direct predecessor before continuing, then 2% (very natural) rate in each production step falls to just 2%*2%=0.0004. So, each (corrected) process step then has just a 0.9996 fail rate, finally resulting in a (0.9996)^200 = 0.92310157 (allover) rate.

Means: Just by switching a small logic in the production process, we no longer have 98% waste but only 8% waste. Controlling last 2 workers finally leads to a 0.99840127 rate, means - just 2 of thousand are defect. Pretty remarkable, isn't it?

That was the core logic, the "miracle", how Porsche became highly profitable again:

What does that mean for software companies? Offering a commonly accessible project wiki and a github definitly is not sufficient!!!!

Have fun!
