Today many firms rely on information systems planning (ISP) to remain competitive by transforming their business model and redesigning their IT architecture. In spite of some great success stories, many firms are having a lot of difficulty with ISP. Previous research has found a number of critical factors for ISP. However, these studies have focused mainly on organizational characteristics. In contrast, our study has taken into consideration organizational work and planning process as main critical factors for ISP performance. Empirical results indicate that the ISP performance has a stronger relationship with ISP planning process rather than organizational work characteristics.
