What's your thoughts on Evidence-Based Management ?

I'd say this should apply to everything we do - as much as possible, make decisions based on empiricism rather than emotions.

@Keith has stated the "master key" with his comment. Scrum framework like other agile based method are evolution of the same methods that were created for object orientation then the basement is software/system engineering. Today object orientation goes unnoticed but it was the "break" in software field that allows all we used today. I know that because I worked with today "cellebrities" in the OOSPLA each year. With that said, evidence-management is not new and it is not created by Scrum, it is taken from practices that are there in software from long time ago (you can go to Tom Gilb work for example). I am using it and I help lot of organizations (including my actual work place) to use and implement it from years. Trying to continue adding information organizational governance frameworks/metods like "stage gate" use it. Knowledge management systems (systems is not synonim of software systems) and today callend big data in convination with AI helps a lot to create and environment to leverage what somebody call "evidence management". The important thing when you implement it at organizational level is try to make people do not feel that you are acting as a "police woman/man" in the process to collect evidences then the evidences are created in a "natural" way.

Dear Kiron
To what extent is that knowledge management in projects and / or organizations can be done using the "Evidence-Based Management" approach?
Does the 7th Edition of the PMBOK Guide include this approach?

Evidence-based management is less about how we manage knowledge but more about what we do with the analyzed data from our projects. As the 7th edition will be more principles than practice-based, my assumption would be that this is not included in detail, but any coverage of adaptive lifecycles would need to reference the importance of an empirical approach.

Agree with Sergio that the idea of EBM is not new and seems to be yet another re-discovery of human ways of working. It is not bad if younger generations discover stuff and are proud of being revolutionary, but older guys smile.

German general von Moltke wrote about 1860 that ‚no plan survives the first contact with the enemy‘ and described ‚mission-based tactics‘ which were used successfully by the German armies in WWI and WWII, the US army deployed it in the 1960s. Mission based tactics basically describe what we call agile today, are based on evidence found as we go and create value.
Not saying that Moltke was the first, Alexander the Great seemed to have used similar ways of working.

We could learn a lot from military. Another example is that there is no merit in strategy planning and handing it over to operations (which leads to 80% of strategy ‚implementations‘ fail, according to PMI Pulse).
What is the strategic plan of a fire department? There is none, they develop and prepare a bunch of strategies and find out what works in every single case.

From frameworks to whatever works.
