How to Build a Winning OEE Business Case: A 5-Step Guide

Mike, a Plant Manager, has a mountain of data showing that his plant's OEE is low and downtime is high. He knows it's a huge problem.

But his COO, Paula, needs more than just operational data to approve a new software investment; she needs a financial plan.

This guide is the translator. It will turn Mike's operational problem into a compelling financial opportunity that Paula and the CFO can't afford to pass up.

This is not just a blog post; it's a project plan. Follow these five professional steps to build an undeniable case.

Step 1: Define the Problem (The Cost of the Status Quo)

The first rule of a business case is to make the pain of not acting crystal clear. Your single biggest, most quantifiable pain is the cost of unplanned downtime.

Use this simple table to put a dollar value on that pain.

This single, powerful number—the multi-million dollar cost of doing nothing—is the foundation of your entire business case.

Step 2: Propose the Solution (The Integrated Platform)

Do not just propose an "OEE tool." This is a common mistake that weakens a business case.

A tool that only diagnoses a problem is an incomplete solution. You must propose a complete, Integrated OEE + CMMS Platform.

Explain that this is the only way to solve both halves of the problem: seeing the problem in real-time (the OEE diagnosis) and systematizing the response to fix it (the CMMS cure).

Step 3: Calculate the Financial Gains (The ROI)

This is the heart of your business case. The most compelling way to do this is to calculate the ROI of the diagnosis and the cure separately.

Gain #1: The ROI of the Diagnosis (Finding Hidden Losses)
This gain comes from uncovering your "hidden factory" with accurate data. For example, your new OEE system might reveal a 10% Performance loss due to slow cycles that was previously invisible.

• Calculation: Value = (Lost Production Capacity in Units x Profit per Unit)

Gain #2: The ROI of the Cure (Taking Faster Action)
This is the powerful, often-missed gain from the integrated CMMS. For example, by slashing your Mean Time to Repair (MTTR) by 50% through automated work orders, you can quantify the savings.

• Calculation: Value = (Downtime Hours Saved x Cost of Downtime/Hour)

When you add the two gains together, you can show the massive, combined ROI of a truly integrated platform.

Step 4: Estimate the Investment

Be transparent and realistic about the costs. A modern, cloud-based system makes this simple.

• One-Time Costs: Include any fees for implementation and training. (Note that for a user-friendly system like Fabrico, these are often minimal or zero).

• Recurring Costs: State the total annual software subscription fee for your team.

Step 5: Present the Recommendation & Payback Period

Bring it all together in a final, executive-ready summary that speaks directly to the bottom line.

• The ROI Formula: [(Total Annual Gain - Annual Cost) / Annual Cost] x 100 = ROI %

• The Payback Period Formula: Total Investment / (Total Annual Gain / 12) = Payback in Months

This allows you to present a killer summary sentence. "With a projected annual gain of $350,000 and a total investment of $30,000, the payback period for this project is less than one month, with a first-year ROI of over 1000%."

What are the implementation risks and how will you mitigate them?

The biggest risk is a lack of user adoption. We have mitigated this by choosing a user-friendly, mobile-first platform that is designed for technicians and operators, not just managers. We will also use a pilot-based approach to prove value on a small scale before a full rollout.

Why can't we just build this ourselves or use our ERP?

Building a real-time system is a massive, costly engineering project that distracts from our core business. Our ERP is a financial "System of Record," not a real-time "System of Action" for the factory floor; it's the wrong tool for the job.

What is the ongoing resource requirement to manage this system?

A modern, cloud-based system is managed by the vendor. Internally, the primary requirement is a project champion (like the Plant Manager) to lead the continuous improvement culture that the system enables.

This business case is more than a request for a budget. It is a clear, data-driven roadmap to higher profitability, lower costs, and a more controlled, proactive operation.

It reframes the conversation from "can we afford to do this?" to "can we afford not to do this?".
