View the essay(s) and the resume as distinct, yet mutually reinforcing documents since they excel at telling different aspects of one's employment "biography."
Keep the following generalizations in mind:
Resume- Summary Information: What, Where, When
Essay- Narrative Account : Why, How
The Resume is best used to convey factual information. If you find yourself talking extensively about how or why something occurred it is probably best left for the essay. Of course, you can provide brief statements of achievement on the resume (Developed new inventory management system that saved firm x dollars each year) that can act as lead-ins to the essay.
The Essay(s) is best at conveying a problem and resolution in vivid detail. Do not take up an inordinate amount of space setting the scene or cluttering the story with extra characters- give enough detail for the reader to understand the crux of the dilemma or achievement and focus on the protagonist (you and your team). If your essay is little more than a dry recitation of your resume in paragraph format, you are squandering this valuable opportunity to communicate with the admissions officers.
