What are the risks associated with introducing more resources and introducing overtime as a means of reducing a project's duration?

What are the risks that the project will be faced with if we introduce more resources and introduce overtime in order to reduce the project's duration? Is doing this really worth it considering the risks?

When you introduce more resources to the project you will have the following issues:

- Communication channels will increase exponentially, which will reduce your team's efficiency. For example, if you have 5 team members, then your communication channels are 10 (formula is N^2/2 - N/2 where N is the number of team members). If you add 5 more team members then you will have 35 additional channels (total will be 45). See how to calculate the number of communication channels in a project here: http://www.projectmanagementquestions.com/1693/how-calculate-the-number-communication-channels-in-project
- You will have to train new resources so that they can be able to work on the project. This will result in team members spending more time training new resources than actually working on the project.
- You will have more conflicts on your team. This will adversely affect productivity and motivation on your team.
- Your team will move down at least one or two levels in Tuckman's stages of team development (for example, if the team is performing it will move down to norming or storming). Again, this is not good for productivity.

When you force the team to work overtime then your team will be burned down and the productivity will be substantially lower even during regular hours (the team is not able to rest).
