Who This Checklist Is For (And When to Use It)
If you're a procurement manager evaluating industrial cable and connector suppliers—like LAPP, or comparing them to alternatives like Cisco's industrial Ethernet offerings—this checklist is for you. It's for those moments when you have a shortlist of vendors, quotes in hand, and need to make a decision that won't come back to haunt your budget six months from now.
This isn't a theoretical framework. It's a 5-step checklist I've refined over 6 years of managing a $180,000+ annual procurement budget. I've used it for everything from cable assemblies to industrial enclosures. And yes, it's saved me from making some expensive mistakes.
Let's walk through it.
Step 1: Get the 'Sticker Price' Out of Your Head
This is the hardest step. The first number you see—the unit price on the quote—is a trap. It's designed to make you feel good or bad, but it doesn't tell you what you'll actually spend.
What I do: I take the quote and immediately add a 20% mental buffer for "stuff I know I'm not seeing." Then I start digging.
In 2023, I was comparing quotes for a high-flex control cable order—2,000 meters of something comparable to LAPP's ÖLFLEX line. Vendor A quoted $4.20/meter. Vendor B quoted $3.85/meter. I almost went with B until I asked about packaging.
Vendor B charged a $90 "bulk packaging fee" per reel. Vendor A included that. On 10 reels, that's $900. Suddenly Vendor A was cheaper. (Note to self: always ask about reel fees.)
Checkpoint: Have you identified every line item on the quote that isn't a unit price? Setup fees, packaging, minimum order charges, documentation fees. List them all.
Step 2: Map the Hidden Costs (The 'Iceberg' Exercise)
I learned this the hard way. After a $1,200 redo when a "cheaper" cable gland supplier's product didn't fit our enclosures (ugh), I started mapping hidden costs before signing anything.
Take a piece of paper. Draw two columns: "Upfront Costs" and "Lifetime Costs."
Upfront is easy: the quote total. Lifetime includes:
- Compatibility testing time. Does this connector from Vendor X work with our existing LAPP SKINTOP cable glands? If not, that's 3 hours of engineering time, minimum.
- Training labor. New termination process? Someone's learning it. Someone's teaching it. That's billable time.
- Inventory management overhead. New SKU means new bin location, new cycle count, new reorder point setup.
- Risk of single-source dependency. If that specialized cable from one vendor fails, what's the cost of downtime waiting for a rushed replacement?
After tracking 180+ orders over 6 years in our procurement system, I found that roughly 70% of our 'budget overruns' came from costs that weren't on the original quote. We implemented a policy requiring a written 'Total Cost Impact Assessment' for any new vendor order over $1,000. It cut overruns by about 40%.
Checkpoint: Have you listed at least three potential non-obvious costs specific to this product type? If not, keep thinking.
Step 3: Compare the 'What If' Scenarios
This is the step most people skip. They compare the happy path. They don't compare the failure paths.
What I do: I build three scenarios for any vendor I'm evaluating.
Scenario 1: Everything goes perfectly. (Rare.) What's the cost?
Scenario 2: One thing goes wrong. (Likely.) A delayed shipment, a wrong part, a spec error. How much does that cost in expedite fees, redo labor, and downtime?
Scenario 3: Multiple things go wrong. (Unlikely, but possible.) Three-month project turns into six. We need emergency parts. What's the total exposure?
In Q2 2024, I was comparing LAPP's industrial Ethernet offering (think their ETHERLINE line) against a Cisco alternative for a new plant floor network. The Cisco quote looked competitive for the switches. But when I ran Scenario 2—a single failed switch requiring a replacement—the costs shifted. LAPP's ecosystem used standard M12 connectors I could get from multiple suppliers. The Cisco system required a proprietary power injector. A rush replacement on the proprietary part? $400 markup. The standard connector? Maybe $50 markup.
I'm not saying one is always better. I'm saying the scenario analysis made the choice clearer for our specific risk tolerance. (At least, that's been my experience with deadline-critical projects.)
Checkpoint: For each vendor, do you know the cost of a single failure scenario? The cost of two? If not, you don't know your risk.
Step 4: Audit the Relationship, Not Just the Product
This sounds soft, but it's pure pragmatism. Products fail. Specs get misinterpreted. Orders get delayed. When that happens, you don't need a vendor who's right—you need a vendor who fixes it.
What I look for:
- Response time to a technical question. Send a question about a spec sheet discrepancy. See how long it takes to get an answer. 24 hours? 3 days? A week?
- Willingness to say 'I don't know.' Vendors who pretend to know everything scare me. Ones who say 'Let me check with engineering' are gold.
- Return process clarity. Ask about returns before you buy. If the process is a maze, you'll pay for it later.
I once audited our vendor spend after a $4,200 annual contract with a cable assembly supplier. The product was fine—nothing special, but fine. The problem was every single interaction required 3 follow-ups. That vendor's 'relationship cost' was at least 8 hours of my team's time per year, which, at our blended hourly rate, was about $560. That was 13% of the contract value, invisible on the invoice.
Checkpoint: Have you estimated the time cost of managing this vendor relationship over a year? Multiply by your hourly rate. That's a real cost.
Step 5: Write the Decision Memo (Even If It's Just for You)
This is my final step. Before I approve a purchase order over $2,500, I write a one-page decision memo. Not for my boss—for future-me.
It answers:
- Why did we choose this vendor?
- What trade-offs did we make? (Assume we made some—we always do.)
- What was our total cost estimate, broken down by the checklist steps above?
- What contingency plan do we have if the vendor fails?
Why? Because six months from now, when the project is over, someone will ask 'Why did we go with LAPP Classic 100 for this instead of the C210 alternative?' I'll have the answer written down. And more importantly, I'll have the data to audit my own decision: was our TCO estimate accurate? If not, what did we miss?
Over the past 6 years, I've built a small library of these memos. They're not fancy—mostly bullet points in a shared drive. But they've saved me from repeating mistakes. 'Oh right, we chose this vendor because Vendor A's warranty support was terrible, not because the cable was defective.'
Checkpoint: Before you approve, write down your decision rationale. Future-you will thank you.
Common Mistakes I Still See (And Sometimes Make)
Mistake 1: Treating all 'premium' products the same. A LAPP cable and a generically labeled one might look similar on a spec sheet. They're not. The flex life, the shielding quality, the jacket material—these are real differences that show up in installation labor and replacement frequency. (I learned this in 2020 when a "compatible" cable failed after 90,000 flex cycles. The original LAPP unit was rated for 1 million. Costly lesson.)
Mistake 2: Forgetting that compatibility has a price. If you're mixing vendors—say, LAPP cables with non-LAPP connectors—expect testing costs. Whether it's a $100 bench test or a $1,000 field trial, that's a cost that belongs in your TCO.
Mistake 3: Assuming 'industry standard' means the same thing to everyone. It doesn't. I made that mistake in my first year. Approved a quote that said 'meets industry standards.' The resulting parts didn't fit because the vendor interpreted 'standard' differently than our engineering team. Fix cost: $600.
One last thing: This checklist was accurate as of late 2024. Cable and connector pricing changes. LAPP might have new product lines. Usual disclaimers about verifying current costs.
But the process? The process doesn't go out of date. Use it. Adapt it. And if you find a missing step, add it—that's how good checklists get built.
