Have you ever faced a problem that wouldn’t go away? You fix it once, only to see it pop up again in another form. Whether it’s a recurring defect in production, a service delay, or a customer complaint that keeps resurfacing, the real issue often lies beneath the surface . That’s where Root Cause Analysis (RCA)  comes in — a systematic approach to identifying the real  causes behind problems rather than treating symptoms. Before we explore tools like the 5 Whys , it’s essent

In Lean Six Sigma, solving problems effectively means going beyond the symptoms and uncovering the true source of variation or waste. This is where Root Cause Analysis (RCA)  plays a critical role. According to ASQ, a root cause  is “a factor that caused a nonconformance and should be permanently eliminated through process improvement” (ASQ, n.d.). RCA, therefore, is not just about fixing what is broken—it’s about preventing recurrence by addressing the core issue  that trigg

In Lean Six Sigma and continuous improvement work, understanding a process is the first step toward improving it. Processes often seem straightforward at a glance, but when mapped and analyzed, hidden inefficiencies, errors, and redundancies come to light. That’s where process analysis tools  come in. These simple yet powerful techniques help teams visualize how work gets done, uncover problem areas, and design better ways of working. Let’s look at four of the most widely use

In Lean Six Sigma and quality management, continuous improvement is not a one-time event—it’s a mindset and a repeatable process. One of the most enduring and effective tools to support this mindset is the PDCA cycle . Simple yet powerful, PDCA (Plan-Do-Check-Act) helps organizations test ideas, implement changes, and sustain improvements in a structured way. What Is PDCA? PDCA, also known as the Deming Cycle  or Shewhart Cycle , is a four-step iterative process designed to f
