Root Cause Analysis is a useful process for understanding and solving a problem. As an analytical tool, RCA is an essential way to perform a comprehensive, system-wide review of significant problems as well as the events and factors leading to them. During the situation analysis, the project team set the vision, identified the problem and collected data needed to better understand the current situation.

Step 2: Identify the Root Cause. Step 3: Identify Communication Challenges. Step 4: Prioritize Communication Challenges. Five whys or 5 whys is an iterative interrogative technique used to explore the cause -and-effect relationships underlying a particular problem.

The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "Why? Each answer forms the basis of the next question. Problem management prevents incidents from occurring and ultimately aims for no incidents. A root cause is an initiating cause of either a condition or a causal chain that leads to an outcome or effect of interest. A " root cause " is a " cause " harmful factor that is " root " deep, basic, fundamental, underlying, initial or the like.

The 5 Whys strategy is a simple, effective tool for uncovering the root of a problem. You can use it in troubleshooting, problem - solving , and quality-improvement initiatives. Start with a problem and ask why it is occurring. Make sure that your answer is grounded in fact, and then ask the question again. RCA takes time and requires resources to be done well.

Events that are chronic, recurring, involving communication breakdown, and are systemic in nature are best for this type of in depth problem solving. RCA is a different process than managing an incident and implementing immediate action to correct the situation. A root cause is defined as a factor that caused a nonconformance and should be permanently eliminated through process improvement.

Root cause analysis RCA is defined as a collective term that describes a wide range of approaches, tools, and techniques used to uncover causes of problems.

Root cause analysis RCA is a tool to help health care organizations retrospectively study events where patient harm or undesired outcomes occurred in order to identify and address the root causes. How to conduct Root Cause Analysis? Define the problem. An error happened when the specifications were being communicated or written down.

Why does the sales person call the head of manufacturing directly to start work instead of following the procedure established in the company? Why does the form contain an approval for the sales director? Once the problem and its causes have been identified, the "Corrective Action" phase begins to determine the measures to take to amend the processes, and thus avoid further occurrences of the problem.

Since these tasks are traceable all the way to testing and release, complete traceability is ensured. Combining RCA with retrospective meetings is a great way for Agile teams to make a long-term positive impact through process improvement. Documenting solutions in an RCA report helps make sure the corrective actions are implemented completely, and it also helps monitor their efficiency.

If your team sees that the corrective measures really help improve their processes, and as a consequence make their jobs easier, they will be more likely to "buy in" and participate fully in an RCA.

Root Cause Analysis and Corrective Action is an effective method for any team, whatever industry they work in, to deductively identify the sources of problems, and take corrective measures to improve their processes. It is particularly useful in the development of safety-critical software. Whether your team is using the Agile framework, a more traditional Waterfall method, or any combination of the two in a hybrid approach, RCCA is an efficient way to prevent problems and improve processes, thus increasing the quality, reliability and safety of products.

By addressing the issue at root, you can drastically improve the final software and save money at the same time. You can also fix fundamental problems with your processes that will benefit not only the current project, but all future projects as well.

According to an IBM white paper [1], the cost of fixing a defect in the testing phase is up to 10 times more than if you catch it in the design stage right at the start.

The cost to fix that same defect in a post-release product is up to 30 times more. The earlier you catch the defect, the more time and money you can save. Customer satisfaction is impaired and a bad experience can do irreparable harm to your reputation.

As the champions of quality assurance, the QA department is best placed to drive forward the use of RCA. It is typically employed to investigate major defects and one-off disasters, but if you carry the methodology through to all defects then you can strengthen its accuracy and realize much greater benefits. A little extra effort in the short term will pay large dividends in the long term. Effective statistical analysis requires as great a data pool as possible and provides your best chance of identifying the patterns that betray a real problem.

Find those problems, dig up the roots, and address the causes, and you can drastically improve your processes. The ultimate aim is closely aligned with the remit of QA — to stop defects reaching the customer, but the side-effects of that include improvements in your processes throughout the software development chain.
