to resolve / a resolution
When you resolve a problem, it means that you find the answer and is commonly used when we’re talking about problems between people. It’s often used with the words ‘dispute’, ‘crisis’ and ‘differences’ and is quite common in personnel management, since one of the roles of human resources is to help people work positively in teams. The word ‘resolve’ is also used when the situation is made more clear – in other words, ‘the ambiguity has been resolved’. The noun is ‘resolution’. So ‘the resolution of a conflict’ is an agreement which ends the disagreement or fighting. The word ‘resolution’ is also used for decisions made by organisations such as the United Nations that some actions need to be taken to resolve some problem.
The partners need to resolve their differences and get on with running the business.
