Hi Mila, 

As a graduate from a PhD program and current KM leader, i may recommend the following: 

- Focus on industrial/ engineering research question. 
- Open up the research scope to management sciences.
- Complement your proposal with a human-centric approach. 
- Discuss how KM has helped to better adopt your solution. 

Any KM topic can be revitalised with new perspectives, at the end this is what the scientific community expects from a researcher.

Hope that has helped.

Thank you
Rachad
