Answer:
A conflict is a situation in which two or more parties with opposing interests collide in their positions when trying to obtain a benefit or satisfy their needs. Thus, for example, if two people want to obtain the same thing, there will be a conflict of interest between those people, since only one of them will be able to satisfy their need.
Thus, two examples of conflict are, on the one hand, the clash of interests over a particular thing (two people want the same thing or position); and on the other, the conflict between two people with different and antagonistic personalities (an extroverted and noisy person against another introverted and reserved).
In all cases, a conflict between two people who are working on the same project could lead to a series of negativities that could affect its outcome.
