The objectives of this research were: 1) to study the implementation of Performance Management (PM) and the problems arising during PM implementation in the Thai automotive companies, and 2) to test the PM model. The mixed methods design was employed. The population in quantitative research method were 433 people who take responsibility in Human Resource Management in the Thai automotive companies. Two hundred of them were selected using the stratified sampling method. A questionnaire was used as the research instrument. In the qualitative research method, 12 key informants were chosen to participate in the focus group discussion. After that, parallel mixed data analysis was employed. The findings revealed that most of the automotive companies in this study implemented the PM at quite a high level, especially regarding performance planning. However, most of the problems encountered during the PM implementation were found in the performance appraisal aspect. It is also proved that the PM model — performance planning, performance development, performance appraisal, and reward for performance—were at a good-fit.
