synergy

Explanation:

Jack is given a project to handle by his team leader, Darren and he is been asked to report about the progress of the project to Darren on a regular basis.

Jack updates Darren about the progress f the on going project that is assigned to him but Darren later finds that Jack will not be able to complete the project at schedule time. That means Jack working alone on the project will not be able to meet the deadline of the project.

Thus Darren assigns two other member to team up with Jack and work on the same project. This will help in completing the project in time. Thus people of similar knowledge and expertise are team up to complete a given project. These people have the same interest and same zeal to work on the project.
