Team members apply knowledge to implement projects and deliver change. Many
studies report inherent challenges and complexities related to knowledge integration and
effective decision-making during project implementation. This paper conceptualises the
relationship between individual competence, team performance, knowledge integration and
decision-making while implementing projects that deliver change. Extant literature is reviewed
to analyse the role of knowledge integration capability in enhancing individual competence
and team performance, and improving decision-making. The paper provides novel insights that
have longer-term implications to support the mobilisation, integration, sharing, and application
of knowledge for effective decision-making to underpin the change process.
