What is Feedback?
What is Feedback?

The application lifecycle doesn’t finish with app deployment. Feedback is an important element of refining an application, whether that’s exception detection and diagnoses or improving the user experience. In this course, we will look at a suite of services that capture a vast array of feedback data, ranging from exceptions to client and server telemetry. This data can be turned into easily digestible information that can be used to trigger alerts and feedback into the development lifecycle as work items.

This course begins by describing what feedback is, and the types of feedback for improving application performance and usability. It then moves on to how we can integrate feedback into the software development lifecycle and what tools we can use to simplify that task. Finally, we will look at optimizing feedback mechanisms to get meaningful data from feedback noise.

What is feedback?

When people think of feedback generally one of two types come to mind, and which one of those will depend largely on how old you are. In the modern consumer marketing world, the younger audience might first think of customer feedback in the form of ratings or surveys. This has become pervasive in our social media-driven society where continuous improvement and customer satisfaction have become corporate clichés. We will look at this later. Older people might first think of audio feedback as first popularized by the likes of Jimi Hendrix. While both of these are examples of feedback, I want to start by looking at feedback loops.

At the elementary level, a feedback loop is where the output of a system is fed back as input into itself. Positive feedback loops tend to amplify a system’s output, as in audio feedback while negative feedback loops tend to make a system more stable, directing it towards an average output. Self-drive cars and machine learning systems are good examples of feedback loops. In the context of application software, we want feedback from the code that will allow us to improve reliability and performance. We take the output metrics from the code and feed it back as input into the development system. In theory, very simple. In practice not so much. I hear you ask “what are these output metrics, and where do they come from?”
