Run a pilot project
Where entering a new arena for development, run a pilot project that will enable you to collect data on which to base your plans.
The forces are akin to those in BuildPrototypes and IterativeDevelopment; early feedback is needed. Here, the feedback is needed in aspects of development process, probably in addition to aspects of the requirements and the technology. Run a small project end-to-end, to gather some information on all aspects of the process. Where prepared to take the hit of re-organization based on the feedback (see StableRoles), and potential re-work of the product, an alternative approach could be EarlyAndRegularDelivery.
