Usability issues regarding feedback systems
Automatic feedback system - Is the feedback of good
enough quality, is it clear enough, is there enough feedback and is it given
quickly enough.
Furthermore with online feedback system where people
provide feedback - Are the people providing feedback of the right skill level
and is their feedback valid?
The inputs to a payroll system are:
·
Employee code (used to lookup the
employee's other details, e.g. name, bank account, etc.)
·
Hours worked
·
Rate of pay (e.g. $25 per hour)
The outputs from a payroll system
are:
·
A printed payslip (given to the employee
to show how his/her pay was calculated)
·
A cheque, or an EFT payment directly into
the employee's bank account
Disadvantages
·
Internet Service Provider (ISP) downtime
·
Depending on the complexity of the system,
employees may have trouble learning how to work with it.
·
Employees might not have a bank in order
to be payed
·
This system might be complex to set up
Voice Recognition
Several problems may occur with a
voice recognition system, they include but are not limited to:
·
The dictionary of the voice recognition
software may be limited and doesn’t include certain words such as slang terms.
·
If the user has a speech impediment then
the software may have trouble recognizing what they are saying.
·
People from different regions of the world
and backgrounds will all different dialects as well as accents which the system
may not be able to deal with.
·
The system may not be able to recognize
different words if the user speaks very quickly or too slowly.
·
Users may not want to speak about
important and sensitive information in a public space. As well as people
speaking in a lower volume when in public, the system may not be able to ‘hear’
the user.
·
Depending on the security capabilities of
the voice recognition system.
·
If the user is in an area with a lot of
ambient noise then the system may not be able to cancel out this noise.
·
If the word database is not stored locally
and there are network errors then the system is not able to work.
