Scenario of entering
data for a new employee using the Banner System
Scenario:
John has just been hired by the College of Human
Resources and Education to fill a position as Associate
Professor in the Instructional Technology Department. He
has filled out his new employee form and turned it in to
the department secretary.
The secretary starts entering the new employee data
into the Banner system. The first page contains general
information on the employee and the secretary fills in
each box with data taken from the paper form. In some of
the boxes she must type in the data, in some she clicks
to see a menu of possible choices for that box. Once the
first screen is completed, she must exit the form, and
save it, then go into the next form to continue adding
data. To enter the data in the different boxes, the
secretary clicks on the appropriate box with the mouse
for some selections, and uses the arrow key to move to
others. After all of the data has been entered, the
secretary saves the form and exits the Banner system.
Claims Analysis
All of the data boxes look the same.
In some you type in data, in others you click and select
from a pull down menu.
- - Having similar material
in a selection box makes it less likely the user
will make an error entering the data.
- but, the boxes are
similar and it is hard to tell which ones require
typing and which have selection choices.
- but, the user may
not remember that some require a mouse selection
and some require typed entry.
- but, the user must
move their hand from the keyboard to the mouse
when entering data via a mouse selection, adding
to the time it takes to complete a form.
When you exit the form, it is not
automatically saved.
- - The form is stored in 'pending' until saved by
the user allowing modifications before the final
form is submitted.
- - If the user needs to leave the computer, the
form is held without loosing data already
entered.
- but, the user may forget to save the form,
holding up processing for the employee.
- but, the user may loose data due to a
system crash and have to re-enter all of the data
for employees.
To select the different data entry
boxes you click in the box with the mouse, or use the
arrow key to select a box.
- - The user can use the arrow key to jump to
different entry points on the form allowing for
quicker access.
- but, the user may arrow over a box that
uses a mouse entry and enter incorrect data in a
different box.
- but, the user must move their hand from
the keyboard to the mouse when entering data via
a mouse selection, adding to the time it takes to
complete a form.
- but, there is no indication to the user
which box uses text data and which uses mouse
selected data causing confusion to the user.
Design Alternatives
- The data entry boxes should all look the same and
work the same. If a box has pre-determined data,
it should be a different shape so the user can
see visually that this entry point is different.
- Saving of data should be automatic on every
change of field allowing for minimal loss of
data. This should be a built in feature, not
something the user must execute.
- Use of keyboard should be available for all data
entry points, and use of mouse should be
available for all entry points. This allows the
user to make the choice based on skill level.
