Combination involves the conversion of explicit knowledge into more complex sets of explicit knowledge. In this stage, the key issues are communication and diffusion processes and the systemization of knowledge. Here, new knowledge generate in the externalization stage transcends the ground in analogues or digital signals.
In practice, the combination phase relies on three processes.
The knowledge conversion involves the process of social processes to combine different bodies of explicit knowledge held by individuals. The reconfiguring of existing information through the sorting, adding, recategorizing and recontextualizing of explicit knowledge can lead to new knowledge. This process of creating explicit knowledge from explicit knowledge is referred to as combination.
