Heidi has just started a new job as a manager of a local gym and is concerned that revenues at the gym are declining. She doesn't know why this is and has come to your research company for advice. Heidi believes a survey of her current members is the best approach to find out why revenues are falling.

Outline a research design for this problem and comment on the manager's suggested approach. In your answer provide a definition of the problem, a statement of the information needed, and an outline of the design of the phases of the research (e.g., an explicit plan for the exploratory, descriptive and/or causal research that you propose should be undertaken).
