![]() Software development is complicated and difficult to plan anyway, but clients/managers/salespeople usually make it harder by changing goals and requirements mid-stream.There are often more iterations where the whole process happens over and over. Design (architecture to a lesser extent) takes place throughout the SDLC on purpose. Newer ways of thinking about the SDLC (see Agile methodologies) somewhat rearrange this traditional approach.(There are already existing databases, conventions, standards, protocols, frameworks, reusable code, etc.) A project might be a part of a larger project, and hence parts of both stages are already decided.Smaller projects often don't have enough scope to separate out planning into these to stages.These two stages will seem to blend together for different reasons. Specification are written during this stage. Design is the smaller picture: the plan for how code will be organized how the contracts between different parts of the system will look the ongoing implementation of the project's methodologies and goals. ![]() Architecture is the bigger picture: the choice of frameworks, languages, scope, goals, and high-level methodologies ( Rational, waterfall, agile, etc.).They are at the same time: different (1) stages, (2) areas of responsibility, and (3) levels of decision-making. In some descriptions of the SDLC (Software Development Life Cycle) they are interchangeable, but the consesus is that they are distinct.
