[Grammar] "desicion making" and "making decision"

[georgelee12071981]

When taking some MBA classes or some training programs, I very often encounter terms like "decision making", "problem solving", "schedule controlling"...etc.
I am wondering their grammatical explanations.
If I say "decision making process", "making" should be present participle and "decision making" should be considered as adjective for "process".
But if I say "guidelines for problem solving and decision making", "solving" & "making" should be gerunds and "problem solving and decision making" should be considered as noun.
Am I right?
Thank you

Also,
Why shouldn't we use "guidelines for solving problems and making decisions"?
Thank you

I would consider them all compound nouns. There is no need to parse the words individually. A "decision making process" is a thing. So are "problem solving" and "decision making".

We could use "guidelines for solving problems and making decisions".
