Question 11

Operation managers are concerned about the increasing attrition rates in the call center. A series of interviews is being conducted with call center agents to collect information to better understand the problem. Interviewees will ask open and closed ended questions that are both quantitative and qualitative. Which of the following is considered a qualitative open-ended question?

Question 12

The results of the data analytics work led to some clear and strongly supported outcomes and the analytics team is very confident in their recommendations; particularly given that the payback on the required changes are a short 3 months. However, there is concern because the organization operates in a highly regulated environment and some new regulatory changes are being considered with announcements and implementation in the next 6 months. Under these conditions the team decides to:

  1. Postpone recommendations for 6 months until the announcements are made
  2. Recommend no action be taken at this time and revisit in 6 months
  3. Identify and carefully document assumptions for their recommendation
  4. Reassess their results to ensure their validity and then decide what to do
