SDEM90: a framework for system development activities and responsibilities

The author presents a system development framework which is derived from a 'space' concept denoting the responsibility for system development activities and 'V-curve' denoting a fundamental principle of manufacturing. This approach is in contrast with conventional process models or standards in which necessary activities are organized in the sense of a preceding/succeeding context. The author's framework is more logical, exhaustive, and understandable to all the parties of people.<
