The TCO breakdowns below compare the in-house development costs with outsourcing costs.
(Table inserted here)
This cost breakdown clearly shows that in monetary terms, outsourcing is the cheaper option with a 23% saving over in-house (proprietary/worst case) development. However, this comparison ignores a number of non-monetary factors. For instance, outsourcing costs while cheaper do present a number of risks including loss of power and control over the development. This means that the project would not be able to adapt well to change. There would also be a risk of revealing business information when outsourcing. In-house development also has certain intangible benefits such as issue/progress tracking, dynamic ability to adapt and respond to change and this allows for the building/expansion of components based on demand and supply. These factors would clearly drive the decision towards in-house development.
