The PDCA Cycle (Deming Cycle): A Complete Guide With Examples

KEY TAKEAWAYS The PDCA Cycle (Plan-Do-Check-Act) applies the scientific method to problem-solving: form a hypothesis, test it, measure results, standardize or adjust PDCA and the Deming Cycle are used interchangeably, though Deming himself preferred PDSA (Plan-Do-Study-Act) and called it the “Shewhart Cycle” Example: A 31-person development team at a bank reduced defects from 93 to 8 (-91%) using better unit-testing, visual management, daily flash meetings, and a developer checklist Example: A QA team reduced false bug reports from 24% to 4% (-83%) using an Andon help signal system and targeted Dojo training Put PDCA into practice → The A3 report is PDCA on a single page.

A3 Problem Solving: A Complete Guide (With Template & Examples)

KEY TAKEAWAYS A3 Problem Solving is a structured one-page method that forces clarity: define the problem, find root causes, implement countermeasures, and confirm results. Successful A3 implementation requires pilot projects, leadership buy-in, and integration into existing team rituals — not a top-down rollout. A tech support team used A3 to eliminate a 145-ticket backlog in 2 months, boosting productivity 72% and customer satisfaction 35%. A tech support team cleared a 145-ticket backlog in 2 months. Here’s the one-page method that made it happen. ...

The 5 Whys: A Root Cause Analysis Guide (With Examples)

KEY TAKEAWAYS Root Cause Analysis goes beyond symptoms to identify core issues – essential for preventing recurring problems and developing sustainable solutions. The RCA process requires methodical validation through observation and data, not assumptions or quick conclusions. A true root cause must meet specific criteria: prevent recurrence, drive systemic change, show clear evidence, and have broader organizational impact. Every morning, from 8 a.m. until noon, a Tech Leader and his team gather around the main accounting screen only to find that the transaction data was outdated. Although the system was designed to refresh the transaction list every hours, it only does so once every morning. This situation is causing a critical delay in decision-making and costing the company valuable time. ...

Why 88% of AI Pilots Fail to Reach Production

KEY TAKEAWAYS 88% of AI pilots fail to reach production. The problem is that teams lack the capability to see problems clearly and solve them systematically. Consultants deliver solutions, not capability. When they leave, the improvements fade. Teams need to own the method, not just the fix. Capability transfers through structured fade. Coaches must progressively withdraw from heavy guidance to not in the room, so teams build independence.

The ‘Top Priority’ Problem: Why Engineering Teams Struggle With Delivery

KEY TAKEAWAYS When everything is marked urgent, delivery stalls. Without real prioritization based on capacity, teams drown in work and nothing flows. Good tools and talent can’t fix broken systems. AI and fast coding mean little if reviews, testing, and handoffs stay overloaded or unmanaged. Leaders must design for flow, not push for speed. The real shift comes from limiting WIP, creating pull, and making the delivery system visible and stable. Does Your Team Have the Same Problem? Take the 3-minute Delivery Flow Scorecard to find out: Your team’s flow score (0-100) Whether you’re pushing or pulling work Your #1 hidden bottleneck Find Your Team’s #1 Bottleneck (Free) → ...

Why Your Dev Team Still Struggles With Delivery – Even With AI, Better Tools, and Great Engineers

KEY TAKEAWAYS Better tools and smarter engineers won’t fix delivery if the system around them is broken. Most bottlenecks come from invisible delays, unclear ownership, and overloaded workflows—not from poor coding. AI accelerates output, but it also amplifies dysfunction. Without flow visibility, fast code creation leads to more rework, review delays, and misaligned priorities. Improving delivery doesn’t require a massive transformation. Start small: make work visible, limit WIP, and fix the handoffs. These simple changes create real, lasting impact. The Pain That Won’t Go Away You’ve hired competent developers. You’ve added AI tools to speed things up. You’ve upgraded your stack, improved your CI/CD, and given teams more autonomy. ...

The Hidden Cost of Vibe Coding: Why AI-Generated Code Creates Technical Debt

KEY TAKEAWAYS AI-assisted “vibe coding” has increased code duplication 8x while decreasing refactoring by 40% in 2024, significantly accelerating technical debt (GitClear’s analysis of 211M code lines). Four technical debt accelerators: “Good Enough” solutions lacking architectural fit, AI’s limited context window creating architectural blindness, duplicated similar solutions, and code growing beyond developer comprehension. Lean Tech implementation strategies: Early validation against real use cases, shortened feedback loops, continuous improvement of AI tools/prompts, and active waste reduction through code simplification. “Vibe coding” burst onto the tech scene when Andrej Karpathy, former Tesla AI director and OpenAI co-founder, coined the term in February 2025. He described it as “fully giving in to the vibes, embracing exponentials, and forgetting that the code even exists.” This new coding approach leverages advanced AI assistants like Cursor Composer to generate code with minimal human oversight. Developers speak commands, accept AI suggestions without review, and troubleshoot by returning error messages to the AI. The code grows beyond the programmer’s comprehension yet somehow functions—at least for weekend projects. ...
