It's a way of keeping track of open issues that, depending on their nature, must be resolved within the next task, before the next milestone, or before the change effort can be finished successfully. While issue tracking originated to track software bugs, the principles can be applied to physical products, customer service maps, and any other aspect of a company that customers engage with. The most challenging part of issue tracking is bringing issues to light. It's vital to have a straightforward and fast manner of reporting and addressing issues, whether internal staff or customers identify them.
