Unlike human cognition, machines can't use heuristics (normally) to guess what a poorly written instruction means, so it's better to know how to handle debugging.
Logical or semantic errors: Implementation errors : Typos and simple errors : Syntax errors : Incremental development Visualization : Use debuggers : Simplification of the problem : Grouping of bugs : Backtracking : It's quite simple: the developer starts with the error and goes back to the code to find out where the problem started.
This is just a small sampling of literally hundreds of methods and styles used to debug code. As you can see, many of these strategies (almost all of them, in fact) cause developers to review code over and over again, and that's where the debugging potential lies.
As the team of developers reviews the code and looks for the source of a bug, they will find themselves looking at their previous work in a new light, and like any change in perspective, this can lead to improvements in both the structure of the code and the software efficiency. It's like tuning an engine!
What is the role of the customer?
Believe it or not, the customer is as important as the developer in debugging, especially in incremental development or when working with agile teams, customers in every sense are testers, in fact, they are the best testers because they are the ones who know what that they really want.
So when a customer spots a bug firsthand, your contribution will help the development team find and eliminate it. Therefore, the customer must always report the bug with as much detail as possible, and if the team is using a data collection tool, the customer must accept and send the report. The more information that is shared with the team, the greater the chances that debugging will be faster and more efficient.
Software development is a system of relationships between the team, the customer and the technology itself. The success of a project is largely due to the way this system communicates. If we stop seeing debugging as a patchwork of poor work and start seeing it as another form of communication within the system, we will be building a network of improvements that will ultimately create the best product.
