7. Consider the situation where you have the following four requirements for an employee information system: Response time for short queries must be less than 1 second In defining an employee record, the user must be able to enter the employee name and be prompted for all the remaining employee attributes that are needed for the employee record. - Employee information may be searched using either the employee number or the employee's last name - Only an authorized search (by the employee, managers in his or her chain of command, or human resource department personnel) will show employee salary, benefits, and family information Perform an analytical hierarchy process and rank these based on your choices.

Explanation / Answer

Answer:

To get the rank with the help of Analytical hierarchy process. Firslty we need to define what is the objective. So for the above case:

Objective - Employee information system.

After that, we need to set our criteria or preferences according to our needs and requirement. One thing to note in this case is that it is subjective and it will change with the different user. so for the above, my priority is to get a secured system rather than the faster speed or details.

So now we will compare the above 4 choices and get the result according to it.

So according to the above comparison, we can rank the above requirement as follows:

Rank 1: Only an authorized search(by the employee, managers in his or her chain of command or human resources department personnel) will show employee salary, benefits, and family information

Rank 2: Response time for short queries must be less than 1 second.

Rank 3: Employee information may be searched using either the employee number or the employee's last number.

Rank 4: In defining an employee record, the user must be able to enter the employee name and be prompted for all the remaining employee attributes that are needed for the employee record.

Hope this helps...If you need any help just comment on it.

Good Luck....!!
