You may know us as Warner Opex. "Opex" is short for operational excellence. It's the same company: Warner Consulting Group, LLC, at warneropex.ai.
What operational excellence actually means
Operational excellence means running the work so problems show up early, get fixed at the root, and stay fixed. It isn't a program with a logo or a binder on a shelf. It's a way of working where the people closest to the work can see the problem, fix the cause, and hold the gain.
In practice, it comes down to three things:
- Clear problems. Everyone agrees on what's actually wrong, and the problem is stated in numbers rather than opinions.
- Real causes. Fixes go after a cause that has been checked against facts, not the loudest theory in the room.
- Plans that run. Every action has an owner and a date, and someone checks whether it worked.
That's the bar we coach to, whether your work runs on a production line, a service desk, a hospital unit or a sprint board.
Consulting or coaching? Why we coach.
A lot of operational excellence consulting works the same way: outside experts study your operation, diagnose the problem and hand you a report. That can help, until they leave and the thinking leaves with them.
We work differently. You bring a real problem you own. We coach the thinking. You keep ownership of the work. You end up with a better plan for this problem and a sharper way of attacking the next one.
AI-powered operational excellence
AI is now part of how a lot of teams run and improve their work. Used well, it makes good problem solving faster and harder to fake. Used badly, it produces confident answers that nobody checked. Our approach to AI-driven operational excellence is simple: AI handles structure and questions, and people handle the facts, the judgment and the decisions.
Where AI helps
- Faster structure. AI can lay out the steps of a problem, ask for the right information at each one and keep the page organized as it fills in. You spend your time on the problem, not on the template.
- Coaching questions on demand. A good coach keeps asking "How do you know?" and "Where does it first show up?" An AI coach can ask those questions whenever you're working the problem, not only during a scheduled session.
- Keeping the A3 honest. AI can flag the usual gaps: a cause hiding in the problem statement, a root cause nobody checked against facts, a countermeasure that doesn't connect to any cause, an action with no owner or date.
Where people stay in charge
AI can't go and see the work. It doesn't know your process, your customers or your team the way you do, and it can sound sure and still be wrong. So the person who owns the problem gathers the facts, decides which causes are confirmed, chooses the countermeasures and checks the results. That's the same line we hold in coaching: We coach the thinking. You keep ownership of the work.
See it working: the A3 Coach app
The A3 Coach is our AI coach for A3 problem solving, and the clearest example of how we use AI. It walks you through an 8-step A3, with a coaching chat on the left and your A3 taking shape on the right. It won't let you skip ahead: each step has to be built from facts before the next one opens. Use it on your own, or to practice between coaching sessions.
- Free demo: a3-coach-phase0.vercel.app. No payment needed to try it.
- Full app: $79/month. Your first month is $39 with code FIRST39.

The tools we bring to the work
Today, our coaching runs through the A3: one page that tells the whole problem-solving story. We bring in other proven operational excellence methods when the problem calls for them, and we skip them when it doesn't.
A3 problem solving
An A3 is a structured, one-page problem-solving story: background, current condition, goal, root cause, countermeasures and follow-up. It keeps a team honest about the problem and focused on what to do next. New to A3s? Start with our A3 problem-solving guide.
Root cause analysis
Fishbone (Ishikawa) diagrams, 5 Whys and, most important, checking each suspected cause against facts before anyone spends money on a fix. Most "solutions" that don't stick were aimed at a symptom.
Lean: waste and flow
Seeing where work waits, loops back or gets redone, and taking those steps out. The same thinking works in a plant, an office, a clinic or a software team.
Six Sigma thinking: variation and data
Using data to tell a real signal from everyday noise, without turning every problem into a statistics project.
FMEA: deal with risk before it hits
Failure Mode and Effects Analysis helps you list what could go wrong in a process or a launch, rank those risks, and act on the biggest ones first.
How coaching works
- Pick a problem worth solving. It should be specific, it should matter, and it should be yours to own.
- Build or sharpen your A3 with guided questions. We ask questions; we don't hand out answers.
- Pressure-test root cause and countermeasures. Does the evidence support the cause? Does each fix point at a cause?
- Leave with a shared plan your team can actually run. Owners, dates and a way to check results.
Coaching today is one-to-one with leaders and managers. The A3 you build is meant to be shared with your team.
Who it's for
Managers and leaders who own outcomes, in manufacturing, services, healthcare, tech or anywhere else work has to get done. It's a good fit if:
- Your team is busy but stuck.
- The same problems keep coming back.
- "Solutions" keep missing the real cause.
- Meetings produce slide decks, not decisions.
- You want to use AI for problem solving without handing your judgment over to it.
Why Warner Opex
- Practical. It's built on thousands of reps in real operating environments, where the work is messy and the stakes are real.
- Plain language. Proven methods without the jargon theater, so your team will actually use them.
- Any industry. The method travels. The coaching meets you where you are.
- AI where it helps. We use AI for structure and coaching questions, not to make your decisions.
- You own it. The goal is a better problem-solver, not a dependency on a consultant.
Frequently asked questions
What is operational excellence?
Operational excellence means running work so problems show up early, get solved at the root cause, and stay solved. In plain terms: clear problems stated in numbers, causes checked against facts, and plans with owners and dates that someone follows up on. It's a way of working, not a one-time project.
What is AI-powered operational excellence?
AI-powered operational excellence means using AI to help people run and improve the work, without handing over the thinking. In practice, AI lays out problem-solving steps faster, asks coaching questions on demand and flags gaps, such as a root cause nobody checked against facts. People still go and see the work, make the decisions and check the results. At Warner Opex, that means one-to-one A3 coaching plus the A3 Coach app, an AI coach for A3 problem solving.
What does an operational excellence consultant do?
An operational excellence consultant helps an organization improve how work gets done. That usually means finding where work breaks down, getting to root causes, and putting better processes in place with methods like Lean, Six Sigma, A3 and FMEA. Some consultants do the analysis for you. We coach your leaders through it, so the capability stays after we're gone.
What is an operational excellence coach?
An operational excellence coach works alongside a leader or manager on real problems and builds their problem-solving skill instead of handing them answers. At Warner Consulting Group that coaching is one-to-one and built around the A3: one page that captures the problem, the root cause, the countermeasures and the follow-up.
Can AI replace an operational excellence coach?
No, and that isn't the goal. AI is good at structure, questions and consistency, and it's there whenever you're working a problem. It can't see your operation, weigh your trade-offs or own the result. We use AI to make the thinking faster and more honest, and the leader keeps ownership of the problem and the plan. The free A3 Coach demo shows the approach.
What's the difference between operational excellence, Lean and continuous improvement?
Lean is a set of methods for removing waste and improving flow. Continuous improvement is the habit of improving the work again and again. Operational excellence is the bigger goal: an organization that runs reliably and keeps getting better. Lean, Six Sigma and A3 problem solving are tools you use to get there.
Is operational excellence only for manufacturing?
No. The methods started on factory floors, but the thinking works anywhere work flows: services, healthcare, tech, offices and support teams. We coach leaders in any industry. The A3 works the same way for a production line, a service queue or a sprint board.

Do you offer root cause analysis coaching?
Yes, as part of A3 coaching. Root cause analysis is the heart of a good A3. We coach you through fishbone (Ishikawa) diagrams and 5 Whys and, most important, through checking each suspected cause against facts before you commit to a fix.
Can you help with Lean Six Sigma or FMEA?
Our background includes A3, Lean, Six Sigma and FMEA, and we use them when the problem calls for them. Lean helps with waste and flow, Six Sigma thinking helps you read variation in your data, and FMEA helps you rank risks before they hit. Our coaching today runs through A3 problem solving. We don't run classroom certification courses.
