Troubleshooting methodologies are structured processes whereby identification, diagnosis, and resolution of problems are effected. Each methodology provides a different framework for troubleshooting a problem efficiently. Some of the most commonly used methodologies in troubleshooting include the following:
The Five Whys
The Five Whys methodology consists of repeated asking of “why” for drilling down to the root cause of the issue. Each answer is the reason for the next question “why”, allowing to go deeper and deeper with each layer being uncovered in the problem (Serrat, 2017). It gives good scaffolding when it comes to simple problems where there is an apparent straight track leading to the solution.
Fault Isolation
It is fault isolation wherein the user systematically eliminates what can be possible causes in order to narrow down the root cause of the problem. This could be done by breaking down the problem into its components and then testing each component separately until the source of the problem is found. This approach is normally used in systems with much interconnectedness.
PDCA Cycle
The PDCA-the Deming Cycle-involves planning of a solution, implementation of the solution, checking of the results, and acting upon the findings. The PDCA is helpful in troubleshooting in environments which demand continuous improvement because it focuses on iterative adjustment towards obtaining better outcomes. Kelley & McGinnis, 2016
Kepner-Tregoe Problem Solving
Kepner-Tregoe Problem Solving is a methodology that emphasizes the use of structured steps to define problems, identify root causes, and select solutions. KT is used for making decisions to select solutions out of many alternatives in usually very complex problems. It relies on data-driven decisions based on structured analyses.
Fishbone Diagram Ishikawa
The Fishbone Diagram, or Ishikawa method, is used to outline visually the causes into categories-material, method, machine, and people-that could be contributing to creating the problem. It is a diagramming method used to identify many causes for a problem in short order. It is primarily used in manufacturing and quality control environments.
Each methodology has its special advantages and is hence applicable only in certain contexts and problem types. The choice of method would depend upon the intricacy of the issue at hand or the precision required in its resolution process.
