Now without looking at the syllabus or any notes. If i'm wrong...well thats just unlucky aye.
"use of appropriate industrial process and equipment" is a production area right? It's just basically the processes and equipment or the way you do things are appropriate to the task and that's seen through your photo diary (if you have one) and the process plan. eg in my project it was appropriate i cut the mortises using a jig on the drill press, it was appropriate cause i had to cut 8 of them and that way itd be faster and more consistent.
"appropriateness of design and/or design modification" again isnt it part of production? is the design itself or any modifications you've made to the design during building it appropriate? for instance is it appropriate to design a desk with a giant hole in the top? no. have a section in your folio where you list the changes you've made to the original design and justify it. You may have decided to use a different type of joints, so tell me that and explain why.
"justification of design" fits into your selection & justification, i believe. justify why you chose a particular joint over another. list the advantages/disadvantages and explain why.
