In general, our bug metric falls below 6 except for the two peaks that we saw in Iteration 3 and 6. According to our bug index, most of the time we will solve these bugs during our debugging session.
For iteration 3, we had a spike due to a critical error that prevented user from logging into the application. This is a critical issue that required immediate fixation, as the entire application was not accessible.
For iteration 6, the critical error that we faced was when the company tried to navigate to the Interview page, s/he got redirected to the Interview page that was designed for job seeker. This is a critical error as it disrupted the entire workflow of our application.
