| Abstract: | Based on multi‐respondent data of 130 innovation projects in hospitals, our study analyses the role of planning intensity for project success. Besides showing that also in complex service systems innovation projects are supported through planning, we contribute to innovation management research, first, by clearly differentiating between the effects of business and project planning; second, by integrating intra‐team co‐ordination as a possible mediator of the planning success relationship; and, third, by taking into account the degree of innovativeness as a relevant contingency. We apply a multi‐level regression analysis, include several control variables, and limit common source biases by a multi‐respondent empirical design. The results demonstrate that both planning types show complementary effects. Project planning increases intra‐team co‐ordination, which mediates the planning effect on project success. Business planning has a direct effect on project success. However, the moderating effects of project innovativeness are oppositional. While business planning becomes more important for higher degrees of innovativeness, the efficacy of project planning is limited to incremental innovations. We conclude with a discussion of implications for hospital and innovation management as well as future research. |
