Worth noting that in each well defined domain area, this can be replied recursively.

I.e. within the domain are the (O) basic structures, relations and operations.

Then (T) practical supporting algorithms, tuned for performance in specific cases, serialize, visualize, or whatever.

Then (A) the code that uses O & A to implement the details of specific solutions or manage specific processes.

Wherever there is a well defined broad class of problems with shared structure, this approach has merit.

• Minimize AT -> A, T, O or X.

• Minimize A -> T, O or X.

• Minimize T -> O or X.

• Minimize O -> X.

Where Blood Type X is... Well its just code that doesn't need to exist. Now all possible code has a blood type. And highest productivity is to increase code in X.

As they say, less (OTA), is more! (X)
