Need for Achievement Theory has been adapted in many studies because it is proven to improve performance. However, the results of exploratory studies show that this theory still leaves many weaknesses, such as being selfish, ignoring coworkers' resources, and only focusing on short-term achievements. Therefore, this study tries to reconstruct the critical concept of NforAch by internalizing Islamic values. Through the spirit of achieving high achievement based on worship, individuals with an Islamic excellence achievement spirit can empower themselves to the fullest and continuously carry out a long-life learning spirit, as well as empower their colleagues through asking and helping activities to achieve the best performance. This concept is believed to be more powerful in improving team performance.
