Software Development Methodology Revolution Based on Complexity Science - An Introduction to NSE Software Development Method

摘要

This article introduces NSE (Nonlinear Software Engineering) methodology based on complexity science. Complying with the essential principles of complexity science, especially the Nonlinearity and the Generative Holism principles results that the whole of a complicated system may exist before building up its components. The characteristics and behaviors of the whole system emerge from the interactions of its components, so that NSE software development methodology suggests almost all software development tasks and activities are performed holistically and globally Complying with W. Edwards Deming's product quality principle that "Cease dependence on inspection to achieve quality. Eliminate the need for inspection on a mass basis by building quality into the product in the first place.", NSE software development methodology is driven by defect prevention and traceability from the first to the final step in order to ensure the quality of a software product. NSE software development methodology supports top-down plus bottom-up software engineering, makes software design become pre-coding, and coding become further design.
