Time and materials is a payment that is more suitable for long-term projects with dynamically changing requirements, an uncertain workload, and different workloads for the development team. It can be useful if the project is still in its infancy and it still lacks data to properly estimate the final cost. There’s also another problem that can occur with fixed-time models.
