QDD Redux: Prioritizing Customer Satisfaction in Product Design (the Kano Model)

How do you balance customer wants with project constraints? If your customer-facing teammates are saying our customers want this, that and the other thing, which ones do we prioritize over others?

Not all features are equal in the eyes of our customers. And not all features are value-added, either.

In this episode, we delve into how to prioritize customer wants using the powerful Kano Model, a tool that maps customer satisfaction against the implementation of product features.

You’ll learn how to differentiate between essential and non-essential features, ensuring that your design truly resonates with your customers. This episode walks through the intricacies of the Kano Model’s two-by-two matrix and the different satisfaction levels represented by various lines and curves.

Too complex? We break it down. Prioritize your features based on their impact to the customer using their voice. Then, consider how well you want to implement that in your design using the Kano Model.

Get ready for practical tips and proven strategies to enhance your product’s value while managing cost, time, and design trade-offs. This episode is an introduction to the Kano Model for design.

Map the User Journey: Design for Seamless Experiences

It’s important to evaluate the customer’s use process during concept development.

Rather than focusing solely on what your product does, understanding how users will interact with it creates opportunities to design more intuitive, enjoyable experiences. By mapping out the steps users take from beginning to end using process flowcharts, development teams gain clarity on inputs, outputs, and the journey between them.

Whether you need to simplify complex steps, compare competitor approaches, or identify critical-to-quality elements, these analytical methods help prioritize design decisions based on what truly matters to users.

The goal is creating products that feel intuitive and natural, preventing those awkward validation testing moments when engineers want to shout, “You’re doing it wrong!” When we evaluate the use process early, we develop products others love while minimizing costly redesigns and user frustration.

Design to Avoid Problems: Focusing on Symptoms Early On

The art of product development is fraught with challenges, but perhaps none is more heartbreaking than hearing negative customer feedback when you thought you were at the finish line.

Picture this all-too-common scenario: after months of development and seemingly thorough customer engagement throughout the process, you finally present your polished product to users only to hear crushing feedback like “I don’t like that” or “That doesn’t work for me.” These late-stage revelations often necessitate extensive redesigns, creating costly delays and team frustration.

This painful experience begs the question: how could we have missed these issues despite our efforts to involve customers along the way?

Slow Down to Speed Up: Jake McKee’s Guide to AIX (A Chat with Cross-Functional Experts)

Dianna Deeney interviews Jake McKee to explore AI Experience Design (AIX), the practice of designing relationships between humans and intelligent AI systems, and how it’s reshaping product development in today’s rapidly advancing technological landscape.

In this eye-opening conversation, Jake draws a powerful parallel between today’s AI transformation and the digital transformation of the early 2000s. The key difference? Scale and speed. While the early web had natural boundaries, AI presents an almost limitless frontier advancing at breathtaking pace. This creates unique challenges for product teams caught between executive demands for AI innovation and the practical realities of implementation. Jake explains how this pressure often leads to a predictable cycle of over-reliance followed by algorithm aversion before teams eventually find balance.

Rather than viewing AI as a replacement for human capabilities, Jake advocates for seeing it as a “creative and critical partner” that enhances our thinking and processes. He shares practical examples of how product teams can thoughtfully integrate AI – from using it to test early concepts against customer data to employing it as a collaborative ideation tool. Throughout our discussion, Jake emphasizes that successful AI integration depends on maintaining human relationships at the center of product development, not pushing customers further away behind technological barriers.

This interview is part of our series, “A Chat with Cross Functional Experts”. Our focus is speaking with people that are typically part of a cross-functional team within engineering projects. We discuss their viewpoints and perspectives regarding new products, the values they bring to new product development, and how they’re involved and work with product design engineering teammates.

Uncovering Customer Desires: Understanding Benefits in Concept Development

In product development, we often get caught up in the technical specifications and features we’re creating, forgetting the fundamental reason we’re building products in the first place: to provide benefits that improve users’ lives. This foundational concept of benefits versus features deserves revisiting regularly, especially when we’re deep in the weeds of development work.

Blank Flipcharts Don’t Make Magic, But Templates Do

In product development, the “fuzzy front end” of concept development often represents both tremendous opportunity and significant challenge. During this critical phase, teams are tasked with defining problems, understanding customers, and generating solutions—all before any engineering begins.

How we navigate this phase dramatically impacts bottom-line results, market share, customer satisfaction, and whether projects even launch at all.

What makes concept development particularly difficult is that teams typically lack something concrete to discuss. Without prototypes or developed products, conversations can become abstract and unfocused. This challenge is compounded when cross-functional team members approach problems from vastly different perspectives, sometimes unknowingly working to solve entirely different issues altogether.

The traditional approach of gathering everyone in a room for open brainstorming sessions has proven remarkably ineffective. Research confirms what many of us have experienced: teams engaged in unstructured brainstorming typically generate fewer ideas, and those ideas are often of lower quality compared to more structured approaches.

The solution lies in using visual models and templates—structured frameworks that guide the creative process and facilitate meaningful team collaboration.

Brighten Your Creative Spark

Ever hit that wall where your creative tank feels bone dry? That moment when you’ve been grinding away at your projects, head down for so long that when someone asks for innovation, you come up empty? You’re not alone.

Creative slumps happen when we get too immersed in our specialized domains. As engineers and designers, we develop expertise through consistent application of familiar tools and techniques. But that same specialization creates mental echo chambers where we recycle the same ideas and follow habitual thought patterns. The result? When innovation is needed most, we feel frustratingly blocked.

The solution lies in cross-pollination – deliberately exposing ourselves to diverse inputs that spark unexpected connections.

AI in Design: Coming Full Circle

As a Generation X engineer, I’ve witnessed remarkable shifts in how we approach design engineering.

Recently, I saw an article suggesting Gen X is frustrated because the skills we learned early in our careers no longer apply in today’s technological landscape. This characterization made me pause and reflect. While our tools have certainly evolved dramatically, I believe we’re experiencing something more nuanced than obsolescence.

With AI in design, we’re coming full circle, with artificial intelligence and machine learning enhancing rather than replacing the fundamental skills we developed.
