Abstract

The revolution in the field of Fawa shows the necessity of continuous development and evaluation of information and communication systems. The purpose of this research is to provide evaluation models in information systems development methods. The sample of this research was 40 specialists in the development and implementation of information systems, who were selected by the purposeful sampling method. The research tool was made by the researcher’s questionnaire for which Cronbach’s alpha test showed acceptable validity and reliability. The collected data were analyzed along with statistical tests during experiments. The findings have shown that the necessary operations in the traditional method are: needs assessment, feasibility study, conceptual and logical design, deployment and implementation, maintenance, reporting and documentation, setting goals, determining performance indicators, cost-benefit analysis and detailed design. is the system. Prototyping methods include: system improvement and development, needs assessment, conceptual and logical design, programming, testing and evaluation, implementation and physical design. In the life cycle method, they are: design, requirements assessment, feasibility study, feasibility report, identification of user information requirements, conceptual and logical design, programming, evaluation and testing, deployment and implementation, delivery, maintenance and development of the system, report and It is documentation. In the organization-oriented method, they are: determining systems and subsystems, information requirements, managing resources and formulating an information strategy. In the object-oriented method, they are: examining the system’s information interaction, system modeling, identifying important events, change diagrams, modeling processes, and drawing data flow diagrams. As a result: different organizations, situations and information systems require the use of different implementation methods, and designers and implementers must act towards the realization of the standard operational measures of each method
