How do you sell an agile project? Most customers expect to buy software by time-and-material or by fixed-price-fixed-scope contracts based on detailed requirements. These models can not create a fertile environment for collaboration between customer and supplier. In this presentation, we will report on our experiments with commercial contracts that supports an agile development process, based on concrete examples of win-win contract types. We will outline the different aspects of these contracts, as well as experiences creating and delivering software solutions under these contracts.
