Seminar paper from the year 2017 in the subject Computer Science - Applied, grade: 3.2, Virtual University of Pakistan, language: English, abstract: This paper is a basic work for introducing the CMMI for in-house software development department. The purpose of this paper is to develop a ground and a clear understanding for the organizations who are willing to adapt the best practices in general for increasing the functional and technical efficiency at their in-house software development department. Normally the CMMI is implemented at organization level in the software development, software engineering, system engineering or system security organizations. The main theme of this paper is to attain CMMI level-2 in software development department. Once the best practices become common in an organization at departmental level, that opens new horizons to build high level understanding of more mature and simplified set of processes that leads toward the organizational maturity which covers the set of overall process areas across the organization. There are various factors involve that limits an organization to adopt a process improvement model. Usually the new emerging organizations having the staff who have previous experience in highly functioning organizations plan to adapt the process improvement models. It is also a dilemma that small and medium size organizations could not establish successful implementation of Software improvement process models because such organizations work in limited resources and restrict time frame 1]. It is more hard to adapt the CMMI at departmental level because main focus of such an organization is towards the productivity or the main stream of the business. Specifically, this paper will provide the structural process and case study of software development department of an organization having very diversified functional and financial dimensions to improve functional efficiency from poorly controlled activities to a managed environ
