Guiding Principles

A seco Dd piece of the architectural guide is, appropriately enough, a set of guiding principles (GPs) to assist development teams in "molding" the product to meet customer preferences. Just as agile values and principles guide people in their efforts, guiding "product" principles assist in steering the product's evolution in the desired direction.!3! GPs are usually not measurable requirements or constraints but conceptual guides. For example, defining the ubiquitous phrase "user friendly" in measurable terms may be difficult. However, a GP stating that "The target user for this medical device, an entry-level medical technician, should be able to use the basic features of the product with minimal training" would help steer a development team in its user interface design. A guiding principle for this book was to focus on delivery "at-ier than comf 1 iance practices.

An early GP may evolve into a specific —-quirem-nt later.
