Co-sourcing

Definition: Co-sourcing is a situation of partial outsourcing, in which a business function or process is performed by both internal staff and by an external party or external resources, such as consultants or outsourcing vendors, with specialized knowledge of the business function.
Compared to full outsourcing, for the traditional owner of the processes, cosourcing has advantages of staying in control, a non-transactional partnership and the ability to grow the own knowledge level of the co-sourced process.
