The embedded sofrware has been developed since the latter half of 1970's. The quality technology of the embedded software that we applied are TQC in 1980's, ISO 9001 in 1990's, and capability maturity mode from 2000. However, the quality problem occurs still. Those Quality technologies are not effective to achieve high Quality. They have only established the procedure of the quality system. It is necessary to improve the quality of process. Products services which fulfills customer's needs and expectation can be offered by applying the process network technology. The process network include not only product realization process but also support process and management process. The process network technology consists of the process network analysis (PNA) technology, the process network design technology (PND), and the process network management technology (PNM). A chronic symptom was analyzed using PNA. The next generation quality technological theme obtained from the analysis is corresponding to the quality technology for sustainable prosperity. An important process is a process where technological succession process and CEO are reeducated. CQO educates engineer, manager, and CEO in the quality. The most important process is an assign process of CQO.
