    Re: Interview

    I would like for you to come to my office next week sometime to discuss the very serious problems that you have in your department. It seems that many of the other managers are upset that their reports are late and never up to date.

    I will be discussing the following topics:

    1. How many people work for you? What are their salaries?

    2. What are the exact duties of each of your employees?

    3. Why do they make so many errors?

    4. What procedures are followed by the data processing department to keep your files up to date?

    5. What kind of reports do other managers need?

    6. How will your staff feel if we automate the entire accounting function and have to lay off the unproductive workers?

    I will use this information in coming up with some better ways of doing the work in your area. I already have some idea of the changes I would like to see and hope you will agree with them. If I am not in my office when you come by, please wait, as I will probably return soon.

  3. Construct questionnaire items to solicit the following information items. The gathered information should be easy to tabulate.

    1. The amount of time an office worker spends:
      • answering the phone
      • filing
      • typing correspondence
      • typing reports
      • writing memos
      • performing other duties


    2. The degree of importance each of the following job dimensions plays in the job satisfaction of an average worker: salary, fringe benefits, co-workers, work environment, amount of supervision, amount of work and other factors.

    3. The salaries of workers paid between $25,000 and $40,000.

    4. The relative importance of each of the following reasons for customer complaints:
      • late deliveries of orders
      • stock run outs
      • damaged goods
      • inaccurate billing
      • poor service
      • high prices
