Generally, for quality improvement of an organization management, TQM (Total Quality Management) is used worldwide and recognized. However, contents of activity are various, and it is difficult for organization to define the whole scope of TQM. It is very important that the activity theme about the TQM is based on the consideration of the needs and priority from the objective requirement, which should correspond to the basic consideration of quality management. If we have selected the wrong theme, and missed understanding about importance and priority of target for TQM, it may cause a significant risk in the organization management. For example, the company which got a high evaluation about the quality of management has poor management and disgraceful affair after several years, and it is a case reaching the bankruptcy. We worked on a study for improvement of technique for quality requirement and evaluation of system for many years, and have participated in the development of international standard for supporting the quality requirements and evaluation of system in ISO/IECJTC1/SC7. The organization having a specific purpose is a kind of system. It is thought that evaluation technique of the system quality is adaptive for a quality evaluation of the organization management. Therefore, this study suggests the new framework of TQM from the view point of the general framework of management defined in ISO/IEC25040 and TQM matrix. Furthermore, this paper presents the result of comparison between proposed action theme derived from a framework of new TQM and the example of existing TQM, and reports an inspection result of the effectiveness.

Software projects influenced by many human factors generate various risks. In order to develop highly quality software, it is important to respond to these risks reasonably and promptly. In addition, it is not easy for project managers to deal with these risks completely. Therefore, it is essential to manage the process quality by promoting activities of process monitoring and design quality assessment. In this paper, we discuss statistical data analysis for actual project management activities in process monitoring and design quality assessment, and analyze the effects for these software process improvement quantitatively by applying the methods of multivariate analysis. Then, we show how process factors affect the management measures of QCD (Quality, Cost, Delivery) by applying the multiple regression analyses to observed process monitoring data. Further, we quantitatively evaluate the effect by performing design quality assessment based on the principal component analysis and the factor analysis. As a result of analysis, we show that the design quality assessment activities are so effective for software process improvement. Further, based on the result of quantitative project assessment, we discuss the usefulness of process monitoring progress assessment by using a software reliability growth model. This result may enable us to give a useful quantitative measure of product release determination.

When introduce a distribution system, it is necessary performing an assessment of system quality generally to evaluate the characteristic of system from candidates targeted product for the purchase and evaluating the superiority and inferiority. The general quality assessment for the system is performed by the integration test based on the quality requirements of the customer till now. But, it is very difficult to perform the integration test completely, because the system testing may depend on the individual person's high skill and experiences. Recently, the method of the quantitative quality requirements and evaluation based on the ISO/IEC9126 quality model is widely recognized for the purpose of a quality evaluation and improvement of the system product. In the precedent study, I have performed the confirmation of the method of evaluation for the system quality from the viewpoint of six quality characteristics included in the quality model defined in ISO/IEC9126, and the effectiveness of whose quality model could have confirmed quantitatively and statistically. However, it is very difficult to assess superiority and inferiority of the system totally even if evaluating the quality of the distribution system from the viewpoint of six quality characteristics for a customer individually. Therefore, if we could display total quality of the target system visually, we could evaluate and compare the total quality of system objectively and intuitively. Based on these assumptions, in this paper, we propose the concept and effectiveness of the "Three Dimensional Integrated Value Model" based on the result of precedent study about six quality characteristics.

For a purpose of suitable system product development and acquisition successfully, it is extremely important to specify the quality requirement for target system during system design phase, and developing or selecting a most suitable product finally from among the alternative candidate products. However, the quality requirements analysis is a very difficult matter because it is non-formulaic and demands much of product customer's technical perceptiveness. Traditionally, analysis of quality requirements of a product has been conducted through questionnaires or interviews with customers based on survey investigator's personal experience. This kind of lack of structure and incompleteness in the traditional approach introduced missing requirements and errors in prioritizing requirements to implement in the requirement analysis of a product. On the other hand, we have been working on developing the techniques (SQuaRE) for quality requirements and evaluation for system and software product for a long time in ISO/IECJTC1/SC7WG 6. For the purpose of specify the quality requirement of system product, the method of quantitative quality requirement definitions based on ISO/IEC9126 [1] quality model that includes six characteristics is widely recognized. However, independency among each quality characteristic is not sure and the suitability of method by using these six quality characteristics for quality requirement is not certified statistically. In this paper, we propose the concept of quality requirements definition method based on the SQuaRE quality models define in ISO/IEC25030 [2,3]. Also, this paper proposes the result of verification about effectiveness of quantitative quality requirement definition approach from the view point of six quality characteristics described in ISO/IEC9126.

ISO/IEC 25030[1] was published in 2007 and ISO/IEC25040[2] was published in 2011. JTC1/SC7/WG6 is currently developing ISO/IEC 25041 based on ISO/IEC 25030[1], 25040[2] and previous ISO/IEC 14598-3, -4, and -5. ISO/IEC 250nn SQuaRE series set of standards can be used for quality requirement and evaluation project. This paper introduces the ISO/IEC 25030[1], 25040[2]and 25041 for specifying quality requirements and evaluation of systems and software products for development and acquisition of them.
