Problem management follows a lifecycle consisting of four main phases: problem identification, problem analysis, problem resolution, and problem closure. Each phase requires its own tools and techniques to help you perform the tasks effectively. In the problem identification phase, you can detect and record problems that cause or might cause incidents using various sources of information such as incident reports, monitoring tools, alerts, audits, feedback, or root cause analysis. Additionally, problem categorization and prioritization techniques can be used to classify and rank problems based on their impact and urgency. During the problem analysis phase, you can investigate and diagnose the root causes of problems using methods such as the 5 Whys, fishbone diagrams, fault tree analysis, or Kepner-Tregoe analysis. Problem documentation and communication techniques are also helpful for recording and sharing your findings and recommendations. The problem resolution phase is where you implement and test solutions to problems using techniques such as change management, risk management, testing, or verification. Problem evaluation and review techniques can be used to measure the effectiveness and efficiency of your solutions. Finally, during the problem closure phase you can formally close problems and update the problem records using various techniques such as a problem closure checklist, problem database, or lessons learned.
