The document discusses how the incident resolution process has changed since the 1980s. It notes that in the past, the process involved manually validating, isolating, repairing, and documenting issues. However, now the process incorporates more automation, guided processes, audit trails, and reporting/analytics to improve efficiency. Specifically, event management systems, ticketing systems, and network devices now integrate to automate parts of validation, isolation, and repair, allowing issues to be resolved faster with better insight into resolutions over time.
