Understanding the "Voice of the Customer" Work on Mini Design Project Assignment: Mini Project single page memo Handout Safety Info and Quiz IED What makes a design attractive?
You need it You think you need it Others have one It's cool IED Why did you buy an iPod ?
You like to listen to music Others have one It's cool The latest technology You didn't, it was a gift IED What makes one design better than another ? Better Quality
1. 2. 3. Improved Performance Special Features Basic Needs
Safety Reliability Maintenance IED Customer Satisfaction
Meets or exceeds customer wants/needs
Delighted Customer Satisfaction e im T E t en em cit x Performance Absent
s Ba ic Fully Implemented Unhappy IED Product Function The Kano diagram for customer satisfaction Class Exercise Make a list of customer requirements for you mini project Use the "voice of the customer" Organize your list into the 3 main areas of customer satisfaction presented by the Kano Model Evaluate whether your list describes "form" or "function" Assign a numerical importance to each customer requirement on a scale of 1 to 5 (5 being most important) IED IED IED Customer Requirements Functional Requirements Things the product must do Performance, capacity, and size related Examples: Thrust, Power, Frequency, Thru put, Memory Capacity Aesthetic requirements Look and feel Smell and taste Sound quality All of these requirements can be measured and quantified IED Technical Requirements Quantification of the customer requirements Ideally each customer requirement is translated into a technical requirement with an associated technical specification Technical specifications consist of A target specification the "optimal" solution Tolerance limits (or constraints) in recognition that variation is always present IED Technical Specifications
Must be unambiguous and verifiable (testable) Low Specification Limit (LSL) Target Specification High Specification Limit (HSL) IED Examples: Light weight Less than 16 oz. High Fuel Efficiency Average to exceed 30 MPG In general ... Requirements should not specify a solution. Why do you think this is true? Possible exceptions:
Company policy Codes and standards Government regulations Which is better? The product shall use an LCD display for presenting information to the user. Or The product shall (visually) communicate information to the user IED Options: LED, plasma, voice synthesis, vibration, etc. Organize Requirements Group related requirements
Example: Automobile R1. Move forward R1.1 Max speed of 150 miles/hour R1.2 0-60 in 5 seconds IED Quality Function Deployment A methodology for translating customer requirements in to technical specifications Work on Mini Project
Do you have a project identified? What are the customer requirements ? What is the critical design parameter? How can it be measured? IED Mini Project Ideas Memo
Hand in written problem statement next class What are your requirements ? Sketch possible solutions What can be measured ? IED Mini Project Ideas - Memo Name / Instructor Project Description / Requirements Make a sketch This can be a hand sketch, system schematic, or flowchart What is the measurable specification?
