Today's competition conditions are challenging companies. On the one hand, it is not easy to try to exist in the market and on the other hand to fight against foreign competitors created by the global environment. Companies have to be one step ahead of the competition. If they can't, it's hard to hold on to the market. That's why they have to produce high quality services and work with world-wide accepted standards.
Aware of these needs, the International Standards Organization (ISO) and the International Electrotechnical Commission (IEC) developed the ISO 1995 Software Process Assessment System standard in 15504. These standards are used especially by software developers and improve the software development processes. It also allows the evaluation of the effectiveness of the processes implemented by software development companies. ISO 15504 Software Process Evaluation System mainly deals with project planning and project management processes, software development process and organizational processes that are experienced in software development processes.
All stages of software development during both production and usage processes are named as software development life cycle. The basic steps in this cycle are: analysis, analysis, design, implementation, testing and maintenance. As the requirements are constantly changing and evolving, these stages are in a continuous cycle. There are different software development process models.
However, the firm, no matter which model it uses, needs to carry out process evaluation in accordance with internationally accepted opinion standards. ISO 15504 Software Process Evaluation System provides this opportunity. Companies that have established Software Process Evaluation System in their organization and operate accordingly, may also wish to obtain the certificate of this system. When applying to a certification body to be selected, it is sufficient for the company to fill in the application form to be obtained from this certification body only. In addition, the system documents for the audits to be made to the certification agency should open.
