A blueprint is a design document that explains in detail how to build an application. Blueprints are used in software development for both internal and external use. An internal blueprint may be used by a team of engineers or designers to create an application, while an external blueprint might be given to a partner organization that will assist in developing the app.
These articles include steps for getting started with an app, technical strategies, and competitor analysis. Additional topics related to blueprints include checklists, walkthroughs, and market research.
