Zevo Chemical Company
Zevo is currently reaching the end of the requirements modeling phase of a new inventory control system for their global
company. As a systems analyst you are asked to support this ongoing project.
Tasks – How would you define total cost of ownership (TCO)? What costs should be included in a TCO estimate? Provide
examples.
A Question of Ethics:
Your supervisor manages the corporate office where you work as a systems analyst. Several weeks ago, after hearing
rumors of employee dissatisfaction, he asked you to create a survey for all IT employees. After the responses were
returned and tabulated, he was disappointed to learn that many employees assigned low ratings to morale and
management policies.
This morning he called you into his office and asked whether you could identify the departments that submitted the lowest
ratings. No names were used on the individual survey forms. However, with a little analysis, you probably could identify
the departments because several questions were department-related.
Now you are not sure how to respond. The expectation was that the survey would be anonymous. Even though no
individuals would be identified, would it be ethical to reveal which departments sent in the low ratings? Would your
supervisor’s motives for wanting this information matter?
