Development and Training Curriculum Effectiveness for Quality Inspection and Control in OEM Automotive Parts Production

Abstract

This research aims to (1) study the inspection and control of production quality of automotive parts in the Input, Production and Output (IPO) units, (2) assess the needs for training in inspection and control of production quality of automotive parts, (3) develop a training curriculum for inspection and control of production quality of automotive parts, (4) measure the efficiency of training and inspection curriculum for inspection and control of production quality of automotive parts, based on the E1/E2 criteria not less than 80/80, (5) calculate the learners’ effective index (E.I) for each training unit, all of which should be greater or equal to the percentage of 60, and (6) assessed after the training curriculum for inspection and control of production quality of automotive parts. Samples used to determine training needs included 486 employees of the contractor companies, 54 companies altogether. Research tools included a rating scale questionnaire with a reliability of 0.902, and the training curriculum developed comprising 3 training units:1) statistical methods for quality control, 2) the use of MIL-STD-105E standard tables, and 3) creating control charts. The training curriculum proposed was measured its congruency with the IOC technique, and their analyzed values ranged from 0.60-1.00. Each training unit was trial out with the KR-21 technique, resulted in the reliability of 0.85, 0.83and 0.71, respectively. The experiment was then conducted with 29 trainees to analyze their E1/E2, Epre-test - Epost-test, percentage, mean, standard deviation, and t-test. The research results revealed the following: 1. Inspection and control of production quality of automotive parts for purchasing department had a less overall average, whereas for the production and transport departments had a moderate overall average. 2. Training needs for inspection and control of production quality of automotive parts for purchasing and warehouse and transport departments were at a high level, whereas for production department was at a moderate level. 3. The training course consisted of 3 units: (1) statistical methods for quality control, (2) the use of MIL-SRD-105E standard tables, and (3) creating control charts. 4. Efficiency of training (E1/E2) was equal to 80.29/81.43, based on the criteria established at 80/80, meaning that the curriculum was efficient. 5. The effective indexes (E.I.) for the training units 1, 2, and 3 were at the percentage of 68.50, 72.76, and 63.55, respectively, all of which were greater than the threshold set at the percentage of 60. 6. Assessed after the training, quality Inspection and control in OEM automotive parts production found that purchasing department and production department with the highest level of satisfaction, and warehouse and transportation, satisfaction was high level.
