I think we all agree there are different evaluations of the numbers and they all come in handy when determining the future of the company and product. As we know, Metrics are needed in order to show variances and thus help us compare to where we need to be. I agree with what ak977 said and what the professor, every metric that we utilised must be measurable, actionable, and visually understandable. I think its a great way to track progress.
One point I found interesting however is psm34’s comment. I had not really considered what and how upper management deems quality or not. I don’t work in the business world, yet, but i had assumed everyone would be on the same page. If the upper management thinks were off track, or could be doing better, when really its just reaching for that “A+” instead of the “A” then that could become a bit aggravating and unnecessary. But if they were to feel that way to better combat our competitors, then maybe its needed to have someone on top with stricter quality demands.
