Conflict Equals Creativity and Representation
Conflict is often seen as a detrimental thing when applied to projects, because it can sometimes hold up the project until the conflict is resolved. However, in the context of a collaborative effort, it allows for people to share their view points, compare each others ideas, and work towards building something that both parties can agree on, or at least until they decide on the better solution. Conflict can also spawn new ideas that neither of the parties had even considered, which allows for an even better result to be applied to the project.
To be honest, my experience with working alongside different cultures of people is limited to brief one-on-one collaborations, but I have managed a team who had different goals, backgrounds, and opinions which ended up breeding a lot of conflict. Despite these conflicts we used them to fuel a lot of really great discussions, which helped us accomplish a lot and ensure that all aspects of the project were being run as equally as we could feasibly could.
The more diverse your collaborative team is, the more conflict is created. This can be invaluable to projects that involve a large group of people that would otherwise have no say in the matter. For example, an agricultural research company can prioritize their research and funding based on the needs of the farmers that grow the food, the sellers of the product, and the people who consume the product by bringing someone from each of these backgrounds to voice their individual concerns. This can also help educate either of the parties in the needs of another party, and help them empathize and come up with a solution that helps them all.
