Two years ago, I found an excellent free online 40-minute course about Earned Value Management. It was in the website of the UK Ministry of Defence (MOD) Acquisition Operating Framework (AOF).
Some days ago, I wanted to check it again and it was still available. If you are interested in the topic, check it.
I have never seen an EVM course as good as this one, no matter how beautiful the name the consultancy training company gives it.
Some time ago I also read a well-structured book on project management, “Guide to Project Management“, by Paul Roberts. I recommend this one too.
