In the context of knowledge-based economy, an organisation’s ability to create knowledge is the most important factor in maintaining its competitiveness. Collective intelligence is posited as a paramount methodology not only for the generation of knowledge pertaining to multifaceted issues but also as a fundamental pillar within the framework of organizational knowledge management. The use of emerging technologies is an important strategy for improving the organisation’s ability to create knowledge through collective intelligence by adding depth and breadth of knowledge. However, excessive use of technology often has a negative impact on organisational knowledge management. Therefore, this study aims to identify the two-sided effect of using emerging technologies (big data analytics (BDA) and online platforms) on organisational knowledge creation according to the complexity of the task. The results of our study suggest that the use of BDA technology for organisational knowledge creation should be maintained at an appropriate level in general, but it is recommended to increase the use of BDA technology for low-complexity tasks. In addition, using online platform technology is difficult to consider as a strategic way to solve high-complexity tasks, but increasing the use of BDA technology can contribute to improving the organisation’s ability to create knowledge.
