This is the last part of a 4 part assignment. I need the following assignment completed as an addition/continuation of the attached document titled “Jackie Hynes – Unit 3 – System Development”. I have attached the instructions for each part of the 4 unit assignment – but this question applies only to Unit 4. I have also attached the feedback from Unit 1, 2, and 3 assignments. Please review the feedback for each of the previous assignments and be sure to incorporate the feedback / make the noted changes. The assignment needs to flow as one document /project. Please review the document and apply Unit 4 as a continuation of the work already done. You will need to support your writing with at least 3 sources written/published in the united states of America within the past 5 years (you may use current/already used sources – if the application to your writing) APA format is to be used with proper punctuation, capitalization, and grammar.
