1.We look here at a broad generalized hypothetical case of a systems integration in your role as a Systems Engineer at an Engineering Manager level serving any product . In this case we are alerted to a functional problem with our system at an interconnection between mechanical and electric subsystems. The Mechanical Engineer responsible for a mechanical subsystem tells us that a problem with main system functionality is not mechanical and the Electrical Engineer responsible for the electrical subsystem of the same system tells you that the problem is not electrical. You will need to first find out which life cycle stage this system currently is in (design, manufacturing quality, etc.). For each life cycle stage, describe how you will investigate, the related questions you will ask, and approach you would take.
