Your team is working overtime to meet a critical project deadline.
Everything looks great until, hours before the release to your customer, a key component starts to fail. You get your best folks on it, but nobody can figure out what’s going on.
With every passing minute, the situation turns heated, your heart starts racing, and you start mentally preparing your “explanation” for the failed release to your boss.
Just as you are about to declare defeat, out of nowhere, Sam - one of your team members - comes up to you and claims to have ‘the fix’. You promptly ask him to apply the fix (and make a mental note to get Sam queued up for a promotion - he deserves it.)
The fix is applied, the problem is solved, and the release goes out on time. Hurrah!
⏳
Three days after the release, a key customer reports an issue with your product.
It turns out it was related to the fix that was applied. And guess what - the impact is worse and your company’s reputation takes a dip for shipping “buggy products”.
Sound familiar?
If you’ve ever patched up a recurring issue only to see it come back, you’re not alone. Managers everywhere struggle with addressing the root cause of problems, not just their symptoms.
In today’s issue, I will discuss the 5 Whys Framework—a simple but powerful problem-solving tool you can use to move away from band-aid fixes into robust solutions.
What is the 5 Whys Framework?
The 5 Whys is a problem-solving technique that helps you identify the root cause of an issue by repeatedly asking “Why?” until you reach the fundamental source.
Originally developed by Toyota as part of its production system, this approach has helped countless teams save time, reduce costs, and prevent future problems.
The magic number five isn’t set in stone—it’s a guideline. Sometimes you’ll find the root cause after three whys; other times, you may need seven.
Why the 5 Whys Works (and Why Most Fixes Don’t)
Most solutions are band-aids. They address surface-level symptoms but fail to resolve deeper issues. The 5 Whys Framework works because:
It avoids assumptions. Asking “Why?” forces you to move past knee-jerk reactions and superficial fixes.
It simplifies complexity. Breaking a problem into smaller, answerable questions makes it easier to understand and address.
It empowers teams. When used collaboratively, it encourages open discussions and insights from different perspectives.
💡 A study by McKinsey found that teams using root cause analysis techniques like the 5 Whys resolved 85% of recurring operational problems compared to just 50% without it.
Real-life Scenarios
Now, let’s look at a few examples to understand this framework better and its power in the real world.
Scenario 1: Machine Stops Working During Assembly
Let’s say you are the manager at a large manufacturing company, and a floor worker informs you that a machine has stopped working during assembly.
What would you do? Your instinct may tell you to replace the fuse, restart the machine, and move on. It should “just work”.
But the problem could be much deeper. Let’s see what the 5 Whys Analysis unfolds for this scenario:
Why did the machine stop? → A fuse blew due to an overload.
Why was there an overload? → The bearing wasn’t lubricated.
Why wasn’t it lubricated? → The lubrication pump wasn’t working.
Why wasn’t the pump working? → The pump shaft was worn out.
Why was the shaft worn out? → No maintenance schedule was in place.
Root Cause: Lack of maintenance schedule for machines on the assembly line.
Solution: Implement a regular maintenance schedule to prevent similar failures. Did you notice how the 5 Whys analysis helped you to dig into the root cause so that you can solve the systemic issue, not just the symptom? That is the power of the framework!
Scenario 2: E-commerce Platform Slowdown
Let’s imagine you are a software manager responsible for an e-commerce platform that is used by millions of users worldwide. One day, you get paged about an issue with the platform: During the flash sale, your customers were facing a slowdown in the performance of your website, which resulted in a poor experience and lost sales.
What would you do? You may be tempted to conclude that you just need to increase the capacity of your servers by scaling them up, which should take care of the increased load during the flash sale.
That might address the immediate problem, but is that really the right solution? Let’s find out what the 5 Whys Analysis reveals in this scenario:
Why did the platform slow down? → The servers couldn’t handle the traffic spike.
Why couldn’t the servers handle the traffic? → The load balancer wasn’t properly configured.
Why wasn’t the load balancer configured? → The configuration was missed during the last system upgrade.
Why was it missed during the upgrade? → There was no checklist for verifying critical system configurations post-upgrade.
Why wasn’t there a checklist? → There’s no standard operating procedure (SOP) for system upgrades.
Root Cause: Lack of a standardized SOP for system upgrades.
Solution: Develop a detailed SOP for upgrades, including configuration checks, and train the operations team on its implementation. Did you notice how the framework helped you to identify the real issue and potentially saved you thousands of dollars of unnecessary cloud computing costs? Once again - that’s the power of the framework!
Scenario 3: Employee Turnover in a Team
Now, let’s imagine that you are noticing a sudden increase in employee resignations in your organization within a three-month period. This is not good as you need your workforce for some time-sensitive projects, and you cannot afford to lose them.
What would you do? You may be tempted to just throw in some arbitrary incentives (one-time bonuses, additional perks, etc.) as a ‘fix’ to this problem.
But that may not necessarily address the problem. Let’s see what the 5 Whys Analysis reveals:
Why did employees resign? → They were dissatisfied with their work environment.
Why were they dissatisfied? → They felt their contributions weren’t recognized.
Why weren’t their contributions recognized? → The manager didn’t conduct regular performance reviews or give feedback.
Why didn’t the manager conduct reviews? → The manager was overwhelmed with other administrative tasks.
Why was the manager overwhelmed? → The department lacked sufficient staffing to balance workload distribution.
Root Cause: Understaffing, leading to overburdened managers and lack of employee engagement.
Solution: Hire additional staff to reduce workload, implement automated performance review systems, and establish a culture of regular recognition and feedback. Once again, the 5 Whys framework helped you to get deeper and identify the systemic issues rather than just applying band-aid solutions.
