Why do bugs have different categories?
One bug is not like another. There are small bugs, there are big bugs.
Your task is to identify bugs, group them and assign them to three different categories: Low, High and Critical.
What is the difference between these categories?
The difference lies in the severity of the errors and the urgency to eliminate them.
Low: Our client should fix this bug but it is no problem if our client decides not to do so. This type of bug does not affect the functionality of a website or a program.
High: This bug should be fixed by our client but there is no hurry.
Critical: This type of bug has to be fixed by our client immediately.
Do I need to consider specific methods for categorizing bugs?
Generally, you have to take the perspective of our client. You have to ask yourself the following questions:
Is the bug so crucial that I could lose customers? e.g: Am I losing customers because they cannot complete their ordering procedure in my online store? Does a bug keep my customers from booking a flight on my website? With no doubt this is a Critical bug!
A graphical error located in the upper left of the web page has to be classified as “Low”, particularly if it is hardly visible.
But what about a graphical error in the logo of the company? Such a graphical bug can be classified as “High”, because this may reduce a company’s trustworthiness.
To sum up:
Bugs are too different to give general instructions to categorize a bug appropriately.
Finally a small hint with respect to the final categorization:
Our client decides about the category at the end. Downgrades and upgrades are possible!
