Not having a positive numeric value entered in the price field would trigger this error message.
The user would close the error message out, correct the error and save their entry. The field that is
missing information would be highlighted red so the user is able to easily determine what entry field
needs to be addressed.
2. Error Message: Stock Field
Not having a positive numeric value entered in the stock field would trigger this error message.
Same as the price error, the user would close the error message out, correct the error and save their

entry. The field needing attention would be highlighted red so the user is able to easily determine what
entry field needs to be addressed.
3. Error Message: “Selection required in Category field”
Not making a selection in the category field would trigger this error message. Same as the price
and stock errors, the user would close the error message out, select one of the two options in the
Page 3 of 5
category field and save their entry. The field that is missing information would be highlighted red so the
user is able to easily determine what entry field needs to be addressed.
Description of Help Feature
For this inventory management system, I think a basic top-level help menu would work well.
Because the system is relatively simple and the entries that the user is making are not too involved,
having a menu section where the user can look through an index of all the different help-tools available
in the system would be helpful. A keyword search function would be available for the index so the user
could search for help on specific issues. Having this help index, paired with the system pop-up windows
for invalid or required fields when entering information into the system, the user should be set for
success.
GUI Violations
There was no error-check put on the data entry fields when the user goes to submit data. This
makes for an awful user experience later down the road when they find that their inventory

management system was doing the opposite of its intended task, due to typos or missed entries that
could have easily been avoided if some simple requirements were placed on those data field boxes.
Using focus and emphasis, the system could highlight a data field red, with text underneath stating the
input error if the user enters a negative number in the stock section or forgets to add information in one
of the data fields.
Another guideline this system didn’t follow well was dividing the information in a meaningful or
sensible manner. Every time the user wants to do anything they have to go up to the menu dropdowns
and sift through their options. It isn’t a very user-friendly design.
