when other external parties are involved in contract execution, it does add complexity and additional risk. By performing tasks internally, there is additional control on the outcomes and results. That being said, depending on the project, this approach not be feasible and some would state that actually outsourcing some of the tasks would help with risk reduction as a means of risk transfer and also not employing additional staff/expertise in house.

Can you/class think of some criteria that an organization/PM need to consider that there is 'balance' between the two approaches?
