This study aims to understand the main factors that contribute to the failure of implementing New Public Management (NPM) plans, as well as to investigate the potential link between informal networks, namely wasta, and this failure in organizations across the Middle East and North Africa (MENA region), with Jordanian public organizations taken as an illustrative case. A qualitative approach was applied, and a total of 24 semi‐structured interviews were conducted with HR officials in Jordanian public organizations, different state‐owned enterprises (SOEs), ministries, and government agencies (GAs). The results show that wasta contributes to the failure of NPM implementation in Jordanian public organizations, indicating that public employees contribute directly to the failure of NPM strategies in Jordanian public organizations for many reasons on top of which their resistance to these reform plans. Our findings also suggest that the implementation of NPM strategies failed to diminish the use of wasta in HRM practices even though wasta was an important reason to implement NPM. This study adds knowledge to the limited informal networks literature, by exploring the interplay between informal networks on one side, and the NPM literature on the other side.
