The 1997 Bank reforms that introduced the matrix management concept aimed to adapt the organization to changing circumstances and address concerns among external stakeholders about the role of aid in development. The reforms were motivated largely by widespread recognition that the Bank s development programs were excessively driven by a culture of lending with insufficient attention to client needs and the quality of results which are crucial to development effectiveness. A previous round of reforms in 1987 had strengthened the country focus but quality remained a concern.
