Design for Six Sigma for Service summary

The first step in designing a superior service? Forget about features for a moment. You need to understand what your customer truly values. While it’s tempting to start brainstorming new functions or cutting costs, these actions are directionless without a clear grasp of the customer’s perspective.

The entire design process should be grounded in a simple but powerful equation: value equals the sum of all perceived benefits minus the sum of all perceived liabilities. Your goal is to engineer a service experience that maximizes this formula, creating a large surplus of value in the customer’s mind. But to do this, you need to deconstruct what “benefits” and “liabilities” actually mean. They’re much more than just performance and price.

Having established what your customers value, you’re now at a critical juncture in the design process. You know, based on your Customer Value Map, which attributes you need to excel at to win in the marketplace. But this strategic knowledge is still abstract, right? Your challenge now is translating a customer desire like “a feeling of security” or “a convenient experience” into concrete engineering specifications, process steps, and staff training protocols.

So this is where you shift gears from strategic analysis to tactical design. The first tool in your arsenal is Quality Function Deployment, or QFD. Think of it as a systematic planning framework that keeps customer needs front and center throughout the design process.

Even a brilliantly designed service product’s value can be destroyed by a poorly designed delivery process. A system that’s slow, inefficient, and full of waste will frustrate both your customers and your employees, regardless of how great the final output is. So once you’ve engineered what your service is, your focus should shift to architecting how it’s delivered.

This brings us to Process Management: the systematic approach to designing and improving the workflows that bring your service to life. The reality is that many service processes, especially those in office environments, evolve organically over time. They accumulate redundant steps, unnecessary approvals, and hidden inefficiencies that no one ever questions. The first step toward excellence? Making these invisible processes visible.

Now that you have the tools to design a valuable service product and an efficient process to deliver it, you can achieve operational excellence. But here’s the thing – in a competitive marketplace, excellence alone won’t guarantee long-term leadership. The final stage of mastery involves moving beyond optimization and learning how to innovate systematically while building a memorable and resilient identity. This is where you create a service that competitors can’t easily copy and customers will never want to leave.

The first step? Adopt a structured approach to creativity, moving beyond conventional brainstorming to a proven methodology for inventive problem-solving. This framework is called TRIZ, a Russian acronym for the Theory of Inventive Problem Solving. Drawn from an analysis of thousands of patents, TRIZ is built on a core insight: nearly every significant invention succeeds by resolving a fundamental technical contradiction.
