Legacy Systems Should Not Be Your Biggest Outage Risk

Your Line Has Contingency Plans. Your Software Should Too.

Hi, I’m Aaron.

I work with Michigan manufacturers to stabilize and modernize the software behind the line without disrupting production. If your team is juggling spreadsheets, scripts, and older platforms that “mostly work,” we should talk.

What You Are Probably Seeing on the Floor

  • Workarounds that only one or two people understand
  • Behavior that drifts from cell to cell because environments do not match
  • Updates that feel risky, so they get delayed
  • Vendor changes, API breaks, or sunset notices that leave you waiting
  • No simple, tested rollback when something goes wrong

Who This Is For

  • You run operations or technology at a manufacturer in Michigan
  • You’ve had multiple plant systems, ERPs, or MES platforms stitched together over time
  • Your engineers are stuck maintaining old systems instead of shipping improvements
  • You’ve tried hiring or throwing tools at the problem, and it didn’t move the needle
  • You’ve been burned by “digital transformation” projects that never landed
  • You want better visibility, faster delivery, and less risk, without a total rebuild
  • You’re making rapid advancements in machine vision, robotics or AI and want your systems to keep up.

The First Move: A Full Systems Audit

You get a map of what you have today, where it is fragile, and a practical plan to fix it without pausing production.

What is included:

  • System landscape map across ERP, MES, SCADA, QMS, CMMS, PLM, HMIs, PLCs, robots, and custom tools
  • Handoff and integration audit across APIs, flat files, schedulers, and scripts
  • Observability review with gaps called out for logging, metrics, and alerts
  • Identity and access check for vendors and internal teams
  • Deployment flow and rollback assessment with a tested fallback path
  • Compliance posture review where relevant
  • Defined pilot with a short backlog your team can start on next change window

What Opreto Solves For The Manufacturing Industry

Problem Opreto's Fix
Staging looks great. But it falls apart in production. We lock down environments early, same configs, same test data, same pipelines across dev, QA, and the floor. If it works in staging, it works on the line. No surprises.
Changeovers feel like a gamble every time. You’re either holding your breath or staying late. We fix that with preflight checks, rollback plans that actually work, and test runs on a single cell before anything goes wide.
One PLC change throws off the rest of the stack. We don’t guess at integrations. Every I/O is versioned, adapters are mapped, and when one tool shifts, the rest keep humming. No more cascading failures.
New programs take weeks to get running. We speed that up. CAD-to-code templates, offline testing, and logic you can reuse. That means hours, not weeks, to make changes stick.
Faults don’t get caught until scrap builds up. We put eyes on the full system, OT metrics, throughput, latency, error rates, so problems show up in dashboards, not scrap bins.
There’s a rollback plan… somewhere. We don’t leave that to chance. Known-good fallbacks are baked in. One command, the system resets, and you’re back to stable without a meeting.
Every station is built from scratch. That’s why scaling is painful. We give you templates, shared logic, and configs you can tune, but still deploy fast and repeatable across every cell.
HMI freezes, interlocks misfire, networks drop. We don’t just “support” the last mile. We build for it. That means operator-first HMIs, solid network planning, and safety that doesn’t crack under load.
MES says one thing, ERP says another. QA can’t trace anything. We clean it up at the source. Clean contracts, structured events, and reliable syncs. You can finally trust what your systems are telling you.

Why Us Instead of Hiring Internally or Going With a Big Vendor?

  • Manufacturing first. Our background is on real shop floors, not just slide decks. We have stood next to cells, debugged during changeovers, and shipped fixes that survive a night shift.
  • Controls native, software fluent. PLCs, HMIs, SCADA, MES, ERP. Rockwell and Siemens, Ignition and Kepware, Fanuc and ABB. We use the stack your team already runs.
  • OT aware, IT compatible. We respect change windows, safety, and quality gates, and we pair that with version control, CI, audit logs, and sane security.
  • Built around manufacturing KPIs. Everything ties back to OEE, first pass yield, unplanned downtime, change failure rate, and MTTR.
  • No rip and replace by default. We stabilize what works, fix brittle handoffs, and reduce vendor lock in so you keep optionality.

Our 5-Step Plan for Modernizing Legacy Manufacturing Systems

We don’t pitch decks. We fix problems. Here's exactly how we start and deliver.

Step 1: Embed & Diagnose

We get boots on the ground. Our team maps your systems, interviews key operators, inspects integration points, and uncovers where things are brittle. You'll get a clear picture of what’s stable, what’s risky, and where you’re bleeding time and budget.

Step 2: Architect & Simplify

We propose architecture that fits your environment, not what’s trendy. Whether it’s augmenting a legacy ERP, stabilizing plant-floor handoffs, or making your MES observable, we design for your real constraints and future growth.

Step 3: Clean & Integrate

This is where most vendors stall, we don’t. We clean data contracts, stabilize brittle APIs, and rebuild handoffs between systems. Every fix is staged, tested, and validated in your environment before it goes live.

Step 4: Measure & Improve

We don’t guess. We measure startup times, failure rates, cycle times, and adoption. We cut form bloat, reduce manual entry, and surface issues before operators feel them. We prove progress in metrics that matter.

Step 5: Scale & Sustain

Once things are humming, we help your team scale cleanly. That means codified delivery pipelines, resilient infrastructure, and playbooks your team can own. You won’t need us forever, and that’s the point.

Let’s Retire Plant-Floor Workarounds, Detroit-Style

We are local on both sides of the river. We work shoulder to shoulder with teams across Metro Detroit from Warren to Livonia, Auburn Hills to Sterling Heights and Pontiac, and a quick hop across the river in Windsor, LaSalle, and Tecumseh.

We know these systems, and we know the pressure you’re under. Let’s make your tech stack boring again, predictable, safe, and fast.

Frequently Asked Questions

Ask Us How We Make Test Day Boring (In a Good Way)

1. Do we need to rip out or replace our ERP?

No. Most of our work is additive and supportive such as fixing handoffs, shoring up APIs, building bridges across tools. We often help you extend the life of legacy platforms without locking into a costly replacement.

2. What if our systems are undocumented or homegrown?

That’s our sweet spot. We reverse-engineer custom systems, build adapters or replacements, and document the logic so your team doesn’t rely on tribal knowledge anymore.

3. We already hired a vendor for digital transformation. Why add you?

We’re often the second call, when big vendors overpromise and underdeliver, or your internal team is spread too thin. We plug in to get traction, clarity, and fixes while they keep chasing the deck.

4. How do you reduce vendor lock-in for assessment platforms?

We’ll specify QTI 3 contracts, version adapters, and document runbooks so you can replace parts without replacing the platform.

5. Is this secure? We operate in regulated environments.

Yes. We build everything to meet manufacturing standards, including identity control, audit logs, encrypted data at rest and in transit, and full change management processes.

6. What’s the actual outcome of the first 2 weeks?

You get a full map of your systems, integration weak spots, and a clear prioritized plan for fixing them. That includes tech architecture, delivery plans, and a scoped pilot we can kick off immediately.

7. What does observability look like for test delivery?

End-to-end telemetry: item-level events, latency/throughput/error dashboards, health checks, and alerts. We run synthetic exams before test windows so issues surface early, so students never see them.

8. Do you actually work onsite in Detroit?

Yes. I’m based in Windsor and come across to work directly with providers in Detroit. Whether you’re in Warren to Romulus, Livonia to Auburn Hills or Sterling Heights to Pontiac, we’ll meet you on your turf.
