Very often it becomes necessary to undertake a major portion of a project on a Fixed Price basis and at the same time deploy resources on a Time and Materials Pricing basis. We call this the hybrid model.
This model is used when client wishes to work on fixed price model and when the project scope is not detailed enough to enable us to estimate the effort with accuracy. Based on the initial concept note we define a short initial.
The effort estimation for all the elements for all stages at the beginning of the project is partly complex. A part of the project is documented and other is defined and executed with both party co-operation.
Client get the advantages of both - Fixed Price & Time & Material
Model.
