Maybe there’s one closer to the client. Detailed design docs might be useful if you’re outsourcing the programming to keep your costs down (though I doubt this practice would achieve the goal in the long run). Software Reference Architecture Project Instructions In this assignment you will create a Software Reference Architecture (SRA) document for a fictitious Information Technology department of a large government agency. OK, if it’s a simple thing and you use a reference architecture, skip the architecture document!

Architecture documentation (also known as software architecture description) is a special type of design document. In simple words, software architecture is the process of converting software characteristics such as flexibility, scalability, feasibility, reusability, and security into a structured solution that meets the technical and the business expectations. To my dismay, someone erased the sketch. We'll also talk about how the architecture touches on the process of software development.
