Certain times projects do not have a clear requirement specifications, in such cases the time and material model can often provide the best solution for the client. After the project has been clearly specked on a T&M Model, the project can be converted to the fixed cost model if the client prefers.

This model provides clients the flexibility to have a team work on their premises, this helps where data security is a concern or if the client wants additional resources to work along with its own team. Highly qualified resources with domain expertise can be provided on-site and billed on a man-month basis.
