My taskstream needs a revsion on section C2 on the presteps I need help writing this on this paper.

My taskstream needs revision I did this section twice already on C2 comments were this near complete essay presents a thoughtful overview of RCA and FMEA concepts that apply to the case study. An Appropriate process improvement plan is developed and Lewin's Change theory is clearly applied. A logical discussion of the published FMEA pre steps could not be located. Can you please help me in this section. The rest of my paper I got a 4 highly competent except for section C2. on the Presteps please help me they gave me a zero.
