The 8D problem-solving method is a structured approach to identify, correct, and prevent the recurrence of quality issues in products or processes. It consists of eight steps or disciplines, each with a specific purpose and outcome. In this article, you will learn how to use the 8D method to solve problems effectively and prevent them from happening again.
The first step is to define the problem clearly and accurately, using data and facts, not opinions or assumptions. You should describe the problem in terms of what, where, when, how, and how many, and quantify the gap between the current and the desired situation. You should also form a cross-functional team with the relevant skills and knowledge to work on the problem.
As an internal auditor, I once came across a sophisticated fraud case involving collusion between a vendor and an employee to embezzle funds. Through the use of data analytics, I was able to pinpoint irregularities in payment records, ultimately uncovering the fraudulent scheme. This experience underscored the significance of meticulous analysis and highlighted the role of technology in early fraud detection.
The second step is to contain the problem by implementing temporary actions that prevent the defect from reaching the customer or affecting other processes. You should verify the effectiveness of the containment actions and communicate them to the stakeholders. You should also identify the potential causes and effects of the problem and document them in a fishbone diagram or a cause-and-effect matrix.
Once while working as an internal auditor, I came across a finance record that was not reconciling and shown huge, vitiated differences. My biggest worry then was the possibility of history financial statements and the company running on thin ice regarding the regulator. Thankfully, I was able to put the fire off by reviewing the accounting processes performance elements and taking immediate measures to remedy the situation. First, I put temporary control functions that would stop the financial bleeding and enhance correct reporting moving forward. After implementing the act, I searched for the cause of the problem, using a fishbone diagram, hand in hand with the finance team.
The third step is to perform a root cause analysis to find out the underlying cause or causes of the problem. You should use tools such as the 5 whys, Pareto analysis, or fault tree analysis to drill down to the root cause and validate it with evidence. You should avoid jumping to conclusions or blaming people, and focus on the process and system factors that contributed to the problem.
In a recent audit, we discovered a recurring issue with late payment of invoices. Instead of just addressing the symptom, we conducted a root cause analysis using the 5 Whys technique. We found that the delays were due to a lack of clarity in the approval process. By improving communication and streamlining the approval workflow, we were able to significantly reduce late payments. This experience taught me the importance of digging deep to find the real causes of problems.
The fourth step is to develop and implement corrective actions that address the root cause and eliminate the problem permanently. You should use tools such as brainstorming, decision matrix, or FMEA to generate and evaluate possible solutions and select the best one. You should also plan and execute the implementation of the solution, including the resources, timeline, and responsibilities.
The fifth step is to validate the solution by measuring its impact and effectiveness. You should use tools such as control charts, histograms, or scatter plots to analyze the data and compare it with the baseline. You should also verify that the problem is solved and that no new problems are created by the solution. You should document the results and celebrate the success.
As an internal auditor, I identified a recurring issue in our expense reporting process that was causing delays and inaccuracies. I proposed a solution to automate the process, which was implemented after thorough testing. The automation reduced processing time by 50% and significantly decreased errors. This experience taught me the importance of continuous improvement and the value of validating solutions before full implementation.
The sixth step is to prevent recurrence by standardizing the solution and updating the processes, policies, and procedures accordingly. You should also train and educate the staff on the changes and ensure that they are followed consistently. You should also review and update the documentation, such as work instructions, checklists, or manuals, to reflect the new situation.
The seventh step is to learn from the problem and the solution by capturing and sharing the knowledge and experience gained. You should also identify and communicate the best practices, improvements, and opportunities for further innovation. You should also recognize and reward the team members for their contribution and effort.
The eighth and final step is to close the problem by formally completing and archiving the 8D report and other relevant documents. You should also thank and disband the team and provide feedback and support. You should also monitor and review the situation periodically to ensure that the problem does not reoccur and that the solution is sustained.
El método de las 8D, también conocido como las Ocho Disciplinas para la Resolución de Problemas, es una metodología estructurada utilizada en la gestión de calidad y resolución de problemas para evitar su recurrencia. Al seguir los pasos estructurados del método de las 8D, se puede abordar eficazmente un problema, identificar sus causas raíces, implementar soluciones efectivas y prevenir su recurrencia, lo que contribuye a una gestión más eficiente y a la mejora continua en cualquier organización.
