A process that leads from an original formulation of a computing problems to executable programs. it involves activities such as analysis, understanding and generically solving such problems resulting in an ALGORITHM, verification of requirements of the algorithm including its correctness and its resource consumption implementation of the algorithm in a target programming language, testing, debugging and maintaining the source code , implementation of the build systems and management derived artifacts such as machine code of a computer programs, the algorithm is often only represented in human parseable form and reasoned about using logic, source code is written in one or more languages (such as java, python, etc.).
