Walk into any mid-size electronics manufacturing business, and you’ll find a familiar rhythm: PCB lines buzzing, operators in ESD jackets soldering components, managers juggling delivery dates, and somewhere in a corner, someone’s pulling their hair out because another unit failed functional test. Now toss Lean into that mix. Suddenly there’s talk of value streams, muda, and gemba walks. Everyone’s excited until, inevitably, the executive team starts asking the dreaded question: “When do we see the ROI?”
If you’re in a business that builds complex instruments—say, laser diffraction particle size analyzers or X-ray diffraction systems—you’ll know this tug-of-war intimately. Lean wants to fix processes systemically. Executives want results fast. The challenge isn’t whether Lean works (it does); it’s whether the business can survive the tension between long-term improvement and short-term pressure.
In this blog post, we explore the complexity of deploying Lean in mid-size electronics manufacturing—especially those producing high-precision instruments—while facing the often contradictory demands of executive leadership. We’ll break down why this conflict exists, what makes your industry unique, and how to keep your Lean efforts alive when the pressure is on.
What Lean Looks Like in Electronic Assembly Businesses
Lean deployment in electronic assembly starts with mapping value streams, understanding flow, and identifying waste. That sounds simple until you realize your products involve hundreds of components, intricate calibration, compliance constraints, and small-volume, high-complexity builds.
In scientific instrument manufacturing, your production process might include:
- Surface mount technology (SMT) lines
- Manual through-hole soldering
- Optical alignment
- Firmware flashing and testing
- Multiple in-process and final quality inspections
Applying Lean here means looking at everything from setup times to Kanban for SMT reels, to 5S in your lab environments. Your takt time might be measured in days, not minutes, and yet Lean still demands a relentless focus on flow.
The early days of deployment usually involve value stream mapping of the end-to-end process—from order entry to final test and shipment. Quick wins might come from reducing batch sizes in SMT, implementing electronic work instructions, or improving first-time pass rates on final system test.
But here’s where things start to go sideways: Lean takes time. You might spend months training people, running pilot kaizens, and fixing systemic issues like poor material presentation or fragmented build documentation. Meanwhile, your CFO is wondering why costs haven’t dropped and your COO is asking why delivery performance hasn’t improved overnight.
Welcome to the Lean vs. Exec dichotomy.
Why Executives and Lean Practitioners Clash
1. Speed vs. Sustainability
Executives are under pressure. Customers want product. Investors want margin. The board wants to see improvement in KPIs now. Lean, meanwhile, says slow down to go faster. Stabilize processes. Invest in people. Build capability.
It’s no wonder conflict arises. Executives push for cost reductions. Lean suggests you first fix problems, then let savings follow. The business wants short-term wins. Lean is a marathon, not a sprint.
2. Cost-Cutting vs. Continuous Improvement
Lean isn’t about cutting heads; it’s about cutting waste. But in many electronics assembly businesses, leadership still equates Lean with fewer people. It’s common to hear, “How many roles will this Kaizen event eliminate?”
Instead, Lean practitioners argue: “If we can improve first-pass yield on our diffraction system build, we won’t need to rework five units a week—think of the labor and reputational cost saved.” But these savings are soft at first. They don’t always show up cleanly in the P&L.
3. Shiny Object Syndrome
Scientific electronics businesses love innovation. But this love can be dangerous. Instead of improving test station reliability, someone buys a new high-speed machine or launches an AI analytics project. Never mind that the old pick-and-place runs at 60% OEE or the test process fails 20% of units due to software instability.
Lean says: fix what you have. Executives say: buy something new. The result? Misalignment.
4. Language Barrier
Executives talk EBITDA, gross margin, revenue per head. Lean coaches talk takt time, standard work, and 8 wastes. It’s like Lean is speaking Japanese and the board is speaking Wall Street. Unless someone is fluent in both, miscommunication is inevitable.
Lean’s job is to make improvement visible in the language of business. Show how reducing changeover time leads to higher line availability, which enables more on-time shipments, which boosts revenue. It’s not just about process—it’s about profit.
Unique Challenges in Your Manufacturing
Your industry is different. Maybe you don’t make to stock; you build to order. Your BOMs are complex, your tolerances tight, and your customer expectations sky-high. Here’s how Lean has to adapt:
– Low Volume, High Mix
Standard Lean approaches designed for automotive lines don’t always apply. You might make 100 units per year of one model, and 15 of another. Takt time is unpredictable. That doesn’t mean Lean doesn’t work—it means you have to tailor it. Focus on reducing setup time, modularizing builds, and creating flexible cells.
– Highly Skilled Labour
You can’t just rotate people across workstations. Your optical alignment technician might need weeks (or even months) of training. So how do you apply standard work? Carefully. Document everything. Train to standard. Eliminate variation where it makes sense and automate where human skill adds little value.
– Regulatory and Compliance Demands
If you’re ISO 17025-accredited or producing for pharma or aerospace customers, you have layers of documentation and traceability. Lean must work with these constraints, not against them. That means building in quality—not inspecting it in—and using tools like poka-yoke and error-proofing to eliminate the need for expensive rework.
Stories from the Trenches: When Lean Hits a Wall
The Kanban That Got Cancelled
One company implemented a Kanban system for their laser diode modules. It cut lead time from 12 weeks to 4. Fantastic! Until a new VP of Operations arrived and, seeing “all this inventory,” promptly canceled the system. Stockouts returned. Shipments missed. Customer complaints spiked. Lean got blamed, and the CI manager quietly updated their LinkedIn profile.
The CEO’s Flash of Genius
During a town-hall meeting, the CEO proudly announced a $1M investment in new test equipment to “solve our yield problem.” Meanwhile, the Lean team had data showing 60% of failures were due to incorrect firmware loads—something that could be fixed with $2,000 of training and a checklist. But the budget was spent. Yield didn’t improve. Lean was told to “try harder.”
How to Reconcile Lean with Executive Demands
1. Translate Lean Wins into Business Language
Don’t say “We reduced changeover time.” Say “We added 12 hours of available line time per week, enabling 8 more systems to ship monthly—worth £600K in revenue.” Make Lean payoffs real. Make them commercial.
2. Show Results Early—Even If They’re Small
Start with visible problems: recurring rework, tool calibration delays, SMT material shortages. Fix them. Measure the impact. Publish the wins. Build credibility. Executive trust follows results, not intentions.
3. Create an Executive Gemba
Get your leadership team on the floor. Not in suits. Not for five minutes. Real walk-the-line, ask-the-team, see-the-problem gemba. Help them see what “normal” looks like so they understand what abnormal costs.
4. Balance ROI Horizons
Split your Lean roadmap. 30% of projects should deliver value this quarter. 70% should build capability and process maturity over 12–24 months. Keep the scoreboard balanced. Feed the execs today while building for tomorrow.
5. Don’t Fight the Business Cycle—Work With It
Budget freeze? Focus on low-cost, high-impact improvements. Team exhausted? Shift to visual management or standard work. Use downturns to train. Use upswings to accelerate. Make Lean your constant, even when the business isn’t.
Common Mistakes in Lean Deployment
- Thinking Lean is Just for Operators – If engineering, quality, and supply chain aren’t engaged, you’re not doing Lean—you’re playing 5S in the corner.
- Starting with Training Instead of Strategy – Lean isn’t a workshop; it’s a business system. Begin with a clear purpose and executive alignment.
- Cutting CI Roles During Cost Crunches – The minute you lay off your improvement people, you’re admitting Lean was just a hobby. Protect the team that helps everyone else improve.
- Ignoring Data – If you’re not measuring first-pass yield, downtime, and takt time, you’re driving blind. Lean starts with facts, not feelings.
- Trying to Copy Toyota – You’re not Toyota. You’re a mid-sized company building complex, low-volume instruments. Take inspiration, but design your own system.
Final Thoughts: Lean is Not an Expense—It’s Insurance
In electronics assembly, complexity is your enemy. Precision, traceability, and speed are your weapons. Lean helps you wield them.
But Lean is not a quick fix. It’s a way to think, behave, and improve—over months and years. Executives want results, and rightly so. But the smartest leaders realise that cutting corners now leads to more fires later.
The trick is to align Lean efforts with business goals. Speak the same language. Focus on value. Share the wins. And never forget: the businesses that master Lean don’t just survive—they dominate. They ship faster, build better, and retain their talent.
So next time your CEO asks, “What’s Lean done for me lately?”—don’t show them a spaghetti chart. Show them a customer shipment that went out on time, under cost, without rework. Then smile and say, “That’s Lean.”
