The act of doing a Plan-Do-Study-Act cycle - is in someways turning tacit knowledge into explicit knowledge I believe, and it's an even more simple and useful way to do so.
The act of planning is already exercising your tacit knowledge, making your skills that you are good at such as your technical skills into use. Now i'm uncertain if this is just tacit-tacit or tacit-explicit, because the tacit knowledge that you have is turning into something tha'ts more physical form, with planning possibly being something you write or document to prepare yourself.
For 'Do' you have to make sure that the actions you take are based on what you plan, and this can come in many form, but essentially this can have 2 effects accroding to Nonaka's model:
1. Tacit - Tacit: because others observe what you do and learn from that
2. Explicit - this might depend on what you choose to do - if it's creating conceptual ideas and spreading it out to use with others - such as if what you planned was think of metaphors, do would be deploying it
'Study' - is where you can take the results and analyse it, which can be something like turnig explicit into explicit or explicit into tacit.
Lastly, 'act' can be when you decide to fully initiate the planned and tested solution, and ensure that this restarts again - to continuously improve - just like what the purpose of the sprial of knowlege is for - to continuously improve at a deeper level.
This is quite interesting and it just came to my head, but doing a comparative study on this might be something useful and very applicable.
