Organizational innovation involves reconciling many contradictions or paradoxes. Dividing the process of innovation into phases ranging from Activation to Validation and examining each phase in terms of the six Ps of creativity offers a framework for making sense of these contradictions. The Innovation Phase Assessment Instrument (IPAI) was designed to assess organizations according to such an approach. The scale was administered to 454 student volunteers and an analysis of their responses indicated that the IPAI is highly reliable and has substantial construct validity. At a practical level, it can be used for assessing the strengths/weaknesses of organizations in a differentiated way and for making recommendations for improving their capacity for innovation. It is also a source of research questions for examining creativity and innovation in an organizational context.
