If I understand your question, then you are being asked to identify all of the important things that need to occur to execute the project effectively.  That is, what things need to happen to complete the project and if they go wrong how will it impact the project.

This is similar to Failure Mode and Effects Analysis (FMEA).

But remember, there's nothing wrong with asking for clarity from your manager.

Ok, link is now fixed....I hope.  Thanks.
