The improvement of software prosess with CMMI and evaluation of software companies according to CMMI 3

With globalizing world and developing technology the level of expectation from the products that consumed by people like everything else has reached to maximum. As in many other sectors increasing customer expectations in software industry has led to development of larger and voluminous software. This growth in software projects has created a quality problem, as it reached the software crisis, in the last quarter of the 20th century. Many factors such as increased technology, changing trade restriction; rising costs, increased customer demand etc. have necessitated various measures in the software sector. To gain resistance and acquire advantage in adverse conditions, the concept of quality has begun to get importance all of sectors also in the software sector. Starting from the middle of 1980s to the end of the nowadays, high quality software products was produced via proses of quality maturity certification and quality management. In this thesis the factors that affect the software development are examined and the quality and process issues are detailed. In this thesis regard, CMMI capability model has been dealt with in detail by demonstrating the important methods and models that have been implemented in order to ensure the quality and quality of process management without developing quality oriented products. In this context an inventory that will measure competence at the level of CMMI 3 maturity was presented and then its validity was tested by applying to companies operating in the sector. In addition we interviewed one of the firms where the inventory was applied by way of face to face interviews with the in depth interview technique. The experience they had during the certifications acquisition process and the benefits they provided afterwards were examined in order to be an example of the firms that wanted to prepare similar quality management process.
