Abstract
From so much number of the result of researches and being paying attention for the quality of solution in market, the target scope of quality engineering researches are getting stable. But, most of the researches seldom to set the target onto the Validation and Verification (V&V) about quality engineering. This kind of problems stem from the difficulty of quantitative measurement such as the cost factors or time factors of project management. This article represents the best practice about validation and verification for the quality management through the author's experiences as the Independent Test Group (ITG) for project upper phase documents. Especially, focusing onto the technical aspects and human resource management aspects through the five core V factors, author shows the recent research area.
