Implementation of such innovation projects must also deliver results in a timely manner, causing firms to make use of agile development methodologies. This study examines several such innovation projects of a telecommunications firm conducted in collaboration with different partner firms. We focus on the conditions that enable or hinder certain formal contracting and informal governance methods under time pressure and high uncertainty. Through interviews with both sides of the collaboration we aim to understand why and which agile coordination practices and contractual arrangements match each other and the varying demands triggered by competitive pressures. Our results indicate that (i) ?compatibility of practices’ impacts how collaboration works, as separate from complementarity of assets and capabilities that motivates collaboration at the first place, and (ii) suitability of contractual forms is contingent on both time pressure and agile practices employed. Our findings also highlight that there is room for innovation in contractual forms in order to match the contemporary contexts of innovation, in addition to innovation in the products themselves.
