Hi guys, can any one of you explain Supply Chain Fitness and Procurement Processes in a simple manner for me?

This is so I can understand them and write about them in a supporting statement. The dumb thing is the person I’m applying for know I don’t have in depth knowledge of this and would be learning on the job but needs me to lie about it on an application so they can shortlist me. (I am also currently the only applicant).

Edit: I attached my new supporting statement. I don’t think it’s great but it’s improved. I did so because a colleague gave me her sign in to the HR system and I am the only applicant still. It closes at midnight.
