I think if your aim is to communicate then indeed we have communicated by using any of the three forms. But for me, the three are slightly different. I think it depends on the context most of the time. For example, “decision-making”, for me, relates more to the cognitive process as it’s studied and its research and “decision making” to the act of making decisions.
If “Decisionmaking” isn’t taken, then I’m going to suggest that it mean “creating decisions”.
(This might be taken literally, particularly in contexts where ‘decisions being made’ is important, or refer to making new options, where “decision making” refers to choosing among options.)
I like “decision-making” the most.
