Maintenance is an essential function in all activities that contribute to controlling costs and avoiding dangerous consequences that can be attributed to a technical system failure or human error. Various scientific departments in universities as well as research centers have begun to pay special attention to the basics of maintenance management, so we find that maintenance is one of the most important activities accompanying for the production process in any industrial establishment.

Hence, the research problem was extracted in the following question: What is the possibility of preparing a computer program for the maintenance of an overlock machine for students of ready-to-wear clothes in technical institutes? What is the effectiveness of teaching a computer program for overlock maintenance in developing the knowledge and skills of students of the ready-to-wear department at technical institutes? Therefore, the research aimed at preparing a computer program in the field of maintenance and also measuring the effectiveness of the program's teaching in terms of developing students 'knowledge and skills on overlocking machine maintenance and measuring the program's effectiveness in terms of knowledge and skill achievement, as well as raising the level of the graduate's competence in maintenance specialization within the industrial sector, where the proposed program was applied (Before, after) on the research sample,
The research problem:
1- What is the possibility of preparing a computer program (for overlock maintenance) for students of ready-made clothes at technical institutes?
2- What is the effectiveness of teaching a computer program (for overlock machine maintenance) in developing the knowledge and skills of students of the ready-to-wear department at technical institutes? Preparing a computer program in the field of (maintenance
Objectives:
Determining the effectiveness of teaching a computer program in developing the knowledge and skills of students of the ready-to-wear department, majoring in maintenance at technical institute  and Raising the level of efficiency of a graduate of the ready-made clothes department, specializing in maintenance, within the industrial sector.
Research Methodology:
The research follows: the descriptive method and the experimental method.
1- Descriptive Approach: To describe and analyze the content of the course "Maintenance of Overlock Machine" for the Second Division, Readymade Garments Department, specializing in maintenance to prepare the proposed program.
2- The experimental approach: to apply the program for "maintenance of the overlock machine" on the sample members to verify the effectiveness of the program.
Results: The results are summarized in the presence of statistically significant differences at a significant level (0.05) between the mean scores of the students in the pre and post applications to measure the effectiveness of the proposed program in the field of maintenance of industrial knitting machines (overlock machine) for the benefit of the post application and thus the first hypothesis was verified. There are statistically significant differences When the significance (0.05) between the average scores of the students in the pre and post application of the cognitive achievement test in favor of the post application and thus the third hypothesis has been verified, there are also statistically significant differences at the significant (0.05) between the mean scores of the students for the pre and post application of the skills for maintenance of a machine Overlocking skill levels in favor of the post application, and thus the program assumptions were verified.
