Assignment: Case Study Mary is the associate director of a nonprofit agency that provides assistance to children and families. She is the head of a department that focuses on evaluating the skill-building programs the agency provides to families. She reports directly to the agency leadership. As a whole, the agency has been cautious in hiring this year because of increased competition for federal grant funding. However, they have also suffered high staff turnover. Two directors, three key research staff, and one staff person from the finance department have left. Mary has a demanding schedule that requires frequent travel; however, she supervises two managers who in turn are responsible for five staff members each. Both managers have been appointed within the last six months. Manager 1: Kelly has a specific background in research. She manages staff who provide research support to another department that delivers behavioral health services to youth. Kelly supports her staff and is…

. Assume that a project has an expected total duration of 25 days, but several optimistic employees feel that it can be completed in as little as 18 days, while others expect it to take nearly 40 days. Using program evaluation and review technique calculations, what is the project duration to be used in project Gantt charts and other tracking tools?2. If a critical path method calculation of project duration was 25 days, how does the program evaluation and review technique calculation in Question 1 compare?
Please enter the "Early Start", "Early Finish", "Late Start" and Late Finish" for each activity, IN THAT ORDER. So for example, the time estimates for Activity A would be 0, 2, 0, 2 respectively, so I would simply enter 0, 2, 0, 2 in the 4 boxes for activity A.
