Section 1
The Clothing Maker's Dilemma
A maker of high-end clothing had a reputation for quality and style, but faced growing competition from cheaper, fast fashion brands. Struggling to keep up, the company considered cutting corners and sacrificing quality to stay competitive, knowing full well that this would ultimately harm the brand they had spent years building.
This is the customer Value trap: without a clear understanding of what customers actually Value, every competitive response is a guess, and the guesses tend to destroy the very thing customers were paying for.
In the Lean approach, customer Value is the measure of how well a product or service meets the needs and expectations of the customer. To succeed, understand what customers Value, then focus on delivering that Value as efficiently as possible. This module gives you the tools to do both.
Section 2
Determining Customer Value
How do you find out what customers Value? Four techniques:
Customer surveys: ask customers directly what they Value and how well your product or service meets their needs.
Customer interviews: one-on-one conversations that reach deeper needs and preferences than any survey can.
Observation: watch customers actually using your product or service. What they do reveals what they Value, sometimes more honestly than what they say.
Market research: study trends and insights about your customer base as a whole.
Notice the pattern: every technique starts with the customer, not with the process. Value is discovered, not assumed.
Section 3
The Kano Model
Developed by Japanese researcher Noriaki Kano, the Kano Model is a framework for understanding customer needs and preferences. It identifies three types of attributes:
Minimum Requirements: basic attributes customers expect to be present, such as quality or durability. Meeting them earns you nothing extra; missing them costs you everything.
Satisfiers: performance attributes customers expect at a certain level, such as price or speed. More is better, and customers consciously compare you on them.
Delighters: excitement attributes customers do not expect, but that greatly enhance satisfaction: new technology, unique design, a surprising kindness.
To use the model, first identify and meet the Minimum Requirements and Satisfiers; those keep you competitive. Then look for Delighters, because those are what set an organization apart and create the opportunity to innovate new Value.

Minimum Requirements never rise above neutral no matter how well you do them. Delighters climb fast even when only partially delivered.
Section 4
Kano at the Hotel
The book's example is a hotel stay:
Minimum Requirements: a clean room, comfortable bed, and relative quiet. Guests who receive only these basics will likely be less than satisfied and will look for problems to complain about.
Satisfiers: a choice of pillows, pleasing complimentary toiletries, updated amenities like a big-screen TV, and a convenient location or lobby dining. Guests whose Satisfiers are met feel good about paying a bit more.
Delighters: a delicious free breakfast, personal greetings and check-ins during the stay, designer bathrooms, interesting views.
Here is the punchline worth memorizing: guests who receive Delighters start leaving positive reviews. Guests who receive only Minimum Requirements often write negative reviews. Guests who experience only Satisfiers usually leave no review at all, and a forgettable stay means they may forget to come back.
Understanding where customers find Value on the Kano Model tells you exactly where to focus improvements and direct resources.
Section 5
Value-Added vs. Non-Value-Added
Every activity in a process falls into one of three buckets:
Value-Added: activities that directly contribute to creating Value for the customer.
Non-Value-Added: activities that do not contribute Value. Eliminating them frees resources for the work that matters.
Non-Value-Added but necessary: activities required by laws, regulations, standards, or policies. The customer gets no Value from them, but the process cannot legally or practically exist without them. Unless the governing policy can be changed, treat them as part of the process: improve and realign them as much as possible, but recognize they stay.
This three-way split becomes a hands-on exercise in Phase 1 of 3-Phase Lean (Module 7), where every step of a Current State Map gets a Green, Yellow, or Red dot. For now, practice the mental habit: for each step, ask which bucket it belongs in, and who says so. The customer's answer is the one that counts.
Section 6
Strategies for Delivering Value
Once you understand what customers Value, deliver it as efficiently as possible:
Focus on the most valuable features: do not try to be everything to everyone. Deliver the features that matter most to your customers exceptionally well.
Eliminate Waste: use the Lean tools from Modules 2 and 5 to streamline processes, so Value moves faster and costs less.
Collaborate with customers: involve them in design and development to ensure you are meeting real needs and expectations, not imagined ones.
Continuously improve: use customer feedback and data to keep improving, because customer needs change over time and yesterday's Delighter becomes tomorrow's Minimum Requirement.
That last point deserves emphasis. Free hotel Wi-Fi was once a Delighter; today its absence is a broken Minimum Requirement. The Kano Model is a snapshot, not a monument. Keep measuring.
Practice
Try It Yourself
Reflect
Think about a product or service you use regularly. What do you Value most about it? How could the company deliver that Value more efficiently?
Activity
For that same product or service, sort its features into the three Kano categories: Minimum Requirements, Satisfiers, and Delighters. Then answer two questions: which Delighter first won you over, and which Minimum Requirement would make you leave if it ever failed? If you work with a team, compare answers; the disagreements are where the insight lives.
Recap
Key Takeaways
Customer Value measures how well a product or service meets the customer's needs and expectations. It is discovered through surveys, interviews, observation, and market research.
The Kano Model sorts attributes into Minimum Requirements (expected), Satisfiers (compared), and Delighters (unexpected joy).
Activities are Value-Added, Non-Value-Added, or Non-Value-Added but necessary (compliance). Eliminate the second, minimize and improve the third.
Deliver Value by focusing on what matters most, eliminating Waste, collaborating with customers, and continuously improving.
Value shifts over time: yesterday's Delighter becomes today's Minimum Requirement, so keep measuring.

Knowledge Check
6 questions. Answer at your own pace, then check the explanation for each.
Question 1 of 6
In the Kano Model, attributes that customers do not expect but that greatly enhance satisfaction are called:
Correct answer: C. Delighters are excitement attributes: unexpected features or experiences that set an organization apart from its competitors.
Question 2 of 6
At a hotel, a clean room and a comfortable bed are examples of which Kano category?
Correct answer: A. Guests simply expect these. Meeting them earns no praise, but missing them produces complaints and negative reviews.
Question 3 of 6
According to the module, hotel guests who experience only Satisfiers (and no Delighters) most often:
Correct answer: C. Satisfiers alone make a stay forgettable. Delighters drive positive reviews; missing Minimum Requirements drives negative ones.
Question 4 of 6
A regulatory compliance check adds no Value for the customer, but the law requires it. In Lean terms, this activity is:
Correct answer: B. Compliance activities are Non-Value-Added but necessary. Improve and realign them where possible, but they remain part of the process unless the governing policy changes.
Question 5 of 6
Which of the following is NOT one of the module's techniques for determining what customers Value?
Correct answer: D. Value is determined by the receiver, not the process owner. Every valid technique starts with the customer: surveys, interviews, observation, and market research.
Question 6 of 6
True or False: A feature that delights customers today will always remain a Delighter.
Correct answer: False. Customer needs change over time. Yesterday's Delighter (like free hotel Wi-Fi) becomes today's Minimum Requirement, which is why continuous measurement and improvement never stop.
