Some problems have many possible resolutions. In these cases, there is often no “right answer”. A plethora of options exist and each will provide the desired outcome.
The multitude of options often leads to fervent discussion, even argument. I am often amused when listening as an independent observer, how, ultimately all parties are basically arguing semantics with the conclusion consistently the same.
Who Cares
Human nature, that is the natural instinctual behaviour for most people, dictates that we want to be accepted. This causes us to care when our solution is not recognized as the best.
Since it is often the case that no solution is necessarily the best this can (and does) lead to non-productive behaviour (usually by all parties to a discussion).
Caring, that is having strong feelings or concerns associated with something translates to being accountable for your own thoughts and actions and is generally a good thing.
In the case where collaboration is the best course of action, ownership can get in the way of achievement. The best course of action can be side-tracked by emotions.
In these situations, it is most helpful if the focus is on the outcomes (what we are trying to achieve) as opposed to an individuals self-worth.
A workable solution
In situations with a number of good options all being elegantly proposed by passionate individuals, I suggest we focus on anything that works and resolves the issue.
Our own personal feelings should be set aside so we may concentrate on achieving a result that benefits everyone.
