Characteristics of Great Products!
Great Products include not only consumer products, but industrial equipment, test fixtures, etc.—real hardware, and processes, like you as a Capstone Team are preparing to create ….
• Great products are well designed • Work properly, reliably, consistently• Provide good performance and value• Are efficient
• Great products “look the part”• Great products make business sense• Great products provide pride of ownership• Great products most often come from great teams• Great products meet and/or exceed customer needs and expectations,
they delight their customers• …..

Uncovering Customer Needs…
• Define project Scope• Project Objective
Statement• Gather Raw Data
• Input from sponsor• Interviews• Focus Groups• Observation• …
• Interpret Raw Data• Need Statements
• Organize Needs• Hierarchy
• Establish Importance• Ranking
• Reflect on the Process• Have we done a
good job? What could we do to make what we have done even better? Integrated Product and Process

• 2: Interpret Raw Data• Need Statements
• 3: Organize Needs• Hierarchy
• 4: Establish Importance• Ranking
• 5: Reflect on the Process• Have we done a

18
Gather Raw Data From Customers• Methods: Interviews, Focus Groups…• Observe the product (or alternate
products), being used in a natural setting • Using a screwdriver to open a paint can• Ask what the user likes/dislikes about the
product• Choose a variety of customers (users)
• Lead users, Users, Service centers• Novice, Skilled, Expert users
• Record the customer’s interactions with the product and the observer• Audiotape, videotape, photos• Survey forms• Capstone Record book

19
The Art of Learning Customer Needs• “Go with the flow”—let the
user express themselves—ask questions…be receptive
• Use props, pictures, etc…• “Suppress” customer’s
preconceived ideas about product…
• Have customer demonstrate the product…
• Be alert for latent needs…• Watch for nonverbal
information• See page 59-61 of U & E…..
20
Tips: Learning From “Customers”
• No substitute for being with customers and users. See them in action…
• Be respectful and genuinely interested in them as people…
• Be eager to be taught, watch & listen carefully…
• Listen and look for impressions and ideas…
• Carefully document what you see, hear and feel…

Customer Needs Statements: Cordless Screwdrivers…

Interpreted Needs: Practice
Customer Statement Interpreted Need
I need to drive screws fast—faster
than by hand. The SD drives screws faster than by hand.
I sometimes do duct work and use
sheet metal screws
I like the pistol grip; it feels the best.
The SD prevents stripping of screw
heads.
I would like an attachment to allow me to reach down skinny holes.
The SD drives sheet metal screws into
metal duct work.
The SD is comfortable to grip.
Sometimes I strip tough screws.
The SD can access screws at the end of deep, narrow holes.
It would be nice if I could punch a pilot
hole. The SD can be used to create a pilot hole.

Tips for Interpreting Needs
• Noun-verb, combination• The device is, does, or can be
used,… to get some desired outcome (whats vs. hows)
• Try and convert the experience you sense the customer expresses they want into a positive attribute or capability of the device….
• Remember What, not How…• …

Guidelines for Writing Interpreted Needs Statements…
Guideline Customer Statement Need Statement-Wrong Need Statement-Right
What, Not How
Specific as User
Positive Not
Negative
Attribute of the
Product
Avoid “Must”
and “Should”
“Why don’t you put protective shields around the battery contacts?”
“I drop my screwdriver all the time.”
“It doesn’t matter if it’s raining, I still need to work outside on Saturdays.”
“I’d like to charge my battery from my cigarette lighter.”
“I hate it when I don’t know how much juice is left in the batteries of my cordless tools.”
The screwdriver battery contacts are covered by a plastic sliding door.
The screwdriver battery is protected from accidental shorting.
The screwdriver is rugged. The screwdriver operates normally after repeated dropping.
The screwdriver is not disabled by the rain.
The screwdriver operates normally in the rain.
An automobile cigarette lighter adapter can charge the screwdriver battery.
The screwdriver battery can be charged from an automobile cigarette lighter.
The screwdriver should provide an indication of the energy level of the battery.
The screwdriver provides an indication of the energy level of the battery.

Customer Needs Process
0: Define the Scope• Mission
Statement1: Gather Raw Data
• Interviews• Focus Groups• Observation• …
2: Interpret Raw Data• Need Statements
3: Organize Needs into Hierarchy (p. 63-66)• Primary (most general)• Secondary…Tertiary
(detailed)4: Establish Importance
• Ranking5: Reflect on the Process
• Have we done a good job?

Hierarchy of Needs
• Use “post-it’s” (or other) method to note needs statements
• Stack/staple redundant needs (be careful here!)
• Group related needs• Make label for each group• If necessary, make groups of
groups• Primary needs are top level of
group headings, secondary next , etc.

IDEO
“Seeing and hearing things with your own eyes and ears is a critical first step in improving, or creating, a breakthrough product.”
“If you’re not in the jungle, you’re not going to know the tiger.”
The Art of Innovation, Tom Kelly

IDEO: Latent Needs“Maybe the meat loaf needs more salt or less onion. The problem is that your guests may like to eat, but they’re probably not food critics. In business, too, your customers may lack the vocabulary or the palate to explain what’s wrong, and especially what’s missing.”
The Art of Innovation, Tom Kelly
34
What Are Latent Needs?
“Important dimensions of customers’ needs that are neither fulfilled nor commonly articulated and understood”
35
Latent Needs
Finding Ways to Meet Latent Needs are The Engineer’s Delight
36
What latent needs does this product meet?
What vs. How
37
The best design engineers thoroughly learn the What…, and then, go after the How…
38
Reflect on the Results and The Process• Have we interacted with all types of users?• Are we able to see beyond obvious needs?• Are there areas we should pursue w/ follow-up
interviews, etc?• Of those we spoke with, who might
be able to help us further?• What did we learn? Any surprises?• Does everyone in our organization deeply
understand what we have learned?• How might we improve the process in the future?• Did we learn of any latent or unspoken needs? • …

Identifying Customer Needs
NEEDS APPROACH• Uncovers latent needs• Focuses on individuals• Happens in natural
contexts• Promotes dynamic
conversations• Generates interpretations
TRADITIONAL APPROACH• Improves existing things• Focuses on explicit needs• Uses market segmentation• Takes place in controlled
settings• Structures interviews• Analyzes objective data
What happens when customer needs are not carefully considered?

Past Capstone Project
Project Objective Statement• Develop a working prototype of an automated machine that
removes nozzle tape from HP inkjet cartridges by April 15, 2003, for less than $10,000
Key Customer Needs• Capable of de-taping 100 cartridges/minute• Does not damage cartridge• Reduce Mfg costs by 60%
Primary Users• Ink jet cartridge manufacturing personnel
Stakeholders• Hewlett-Packard• Plant workers• Ink jet cartridge consumers• BYU Capstone Team
Key Constraints• Must run on 110 volt power

Summary
• Five steps in establishing customer needs…• Gather raw data…• Interpret data…• Organize needs…• Establish importance and prioritize! • Reflect on the process…
• Customer needs should guide the entire development process …
• Process establishes important communication links and relationships for future development needs…
48
Summary (Cont’d)
• Lead users are an important source for learning needs
• Latent needs may be more important than explicit needs
• Customer needs should be expressed in terms of what the product will do, not how it will do it…
• Key benefits of using this process is to help insure that the design you create will meet customer needs…

Ok, So What is Engineering Design?
Design in a major sense, is the essence of engineering; it begins with the identification of a need and ends with a product or system in the hands of a user. It is primarily concerned with synthesis rather than analysis (which is central to engineering science). Design, above all else, distinguishes engineering from science.
(Hancock, 1986)
