Reader’s question: Should decision making be hyphenated, i.e. decision-making?
Answer: You can use either decision making or decision-making.
Just be consistent.
Everyone in the team had a role in the decision making.
Everyone in the team had a role in the decision-making.
Hyphenate decision-making when the two words act as a unit and have an adjectival meaning, e.g. decision-making paper.
The decision-making process lasted for weeks.
If in doubt about whether to use a hyphen, consult your favourite dictionary.
PS Since writing this post, I think that decision-making is gaining in prominence. The Chicago Manual of Style now recommends a hyphen and the online Macquarie Dictionary says decision-making.
