Furthermore, the objective of this study is to emphasise the importance of applying information systems strategies (ISS) such as knowledge capture and utilisation to make better firm processes to boost firm performance in knowledge management process-intensive organisations. The study surveyed 261 Brazilian companies and used partial least squares path modelling to test the hypotheses proposed herein. The research findings showed that KG and KC influence ITI. Additionally, it also showed that ITI has full mediation in its relationship with KG and SDSS and partial mediation in its relationship with KC on the SDSS. Finally, BPP demonstrated full mediation in its relationship with SDSS and FP. The research findings contribute to firms understand how BPP and FP are affected through ISS embedded into knowledge and utilisation coupled with knowledge generation and sharing. 收起
