My only guess is a software factory is like a boilerplate starting point and I'm still not sure
For home stuff I've shifted to a software day spa
But for work, I've gone a step further and now run a software CPG distribution center combined with a software recycling plant.
The code flows out of the DC, gets consumed by the business and then tossed back to the recycling plant, fully green from a 1's and 0's perspective.
