Value flow oriented software research and development efficiency measurement method and visualization system thereof

The invention relates to a value flow-oriented software research and development efficiency measurement method and a visualization system thereof, research and development process data required by index calculation are collected, and the research and development process data comprise data in demand, design, development, test, release and operation and maintenance stages; after the research and development process data is subjected to efficiency calculation based on an index system to obtain a target attribute metric value, a research and development efficiency comprehensive metric value M is finally obtained through calculation according to the following formula: M = (P + Q + E + C + V + I)/6, and a visualization technology is used for visually displaying the whole process efficiency dynamic change of the multiple target attributes. Therefore, problems in the research and development process can be found based on the value flow to improve the research and development efficiency. Wherein the target attribute m
