Aiming at no less than a paradigm shift, Lean Architecture uses a modern approach to software design, while embracing refreshing new insights of Lean and Agile. is to the programmer as the classic MVC architecture is to the end user: a software approach that puts people first. Last, but certainly not least, architecture should inspire a human sense of delight (venustas). May 10-28, 2021 Architecture is not without an engineering component that encompasses materials and techniques of construction, as good construction must be durable (firmitas) and architecture, arguably, is timeless.

The principles were adapted from lean manufacturing by Mary and Tom Poppendieck. Second principle of lean software development is – amplifing learning. Good Software Architecture embodies several Lean and Agile principles, always with the same goal of long-term productivity and lightweight feature development. Software architecture refers to the fundamental structures of a software system and the discipline of creating such structures and systems.
