I think there is a world market for maybe five
computers.
Conventional Wisdom A Rogues Gallery
-- Thomas Watson, chairman of IBM, 1943
There is no reason anyone would want a computer
in their home.
Ken Olson, President, Chairman and Founder of
Digital Equipment Corp., 1977
640K ought to be enough for anybody.
Bill Gates, 1981
What do 13 people in Seattle know that we dont?
Ross Perot when presented with a proposal for
EDS to acquire Microsoft, 1980

Five Objectives of Every Project Gate Review
  • Explain the Benefits of the Technical Solution or
    Technology
  • Show the Technical Feasibility of approach and
    solution
  • Show the Balance of Performance to Business
    Imperatives
  • 4) Explain the Risks
  • a) Business.
  • b) Application Timing.
  • c) Technical.
  • 5) Explain the Expected Engineering Expenses
    Costs.

Risk
13
Risk
  • Types of Risk
  • (things gone wrong, or critical items not going
    right)
  • Business
  • Timing
  • Technical
  • Quantify Relative Risk
  • Risk f(L,M) (Likelihood) X (Magnitude)
  • Method
  • Brainstorm Potential Problems
  • Define Likelihood of Occurrence (1 -10 scale)
  • Define Magnitude should problem occur (1-10
    scale)
  • (Risk Priority Number) RPN (Likelihood) X
    (Magnitude)
  • Rank order into a bar chart (Pareto Diagram)
  • Define Countermeasures

  1. Problem Definition
  2. Containment, Immediate Corrective Action
  3. Root Cause
  4. Irreversible Corrective Action
  5. Verification

ExampleMultifunction Headlamp Switch
Functions
Headlamp On / Off
Headlamp High / Low
Electrical Control
Customer
Turn Signal
Component test plan was designed to test each
function as independent variables All part
passed the lab test without incident
Cruise Control Set, On, Off
25
ExampleMultifunction Headlamp Switch
Functions
Headlamp On / Off
Headlamp High / Low
Customer
Electrical Control
Turn Signal
However Mechanical Interaction Inside
the Multifunction Switch caused the headlamp
contact carrier to slightly rock when the Turn
Signal was used.
Cruise Control Set, On, Off
This caused a voltage spike and high resistance
path and heat in the switch.
26
ExampleMultifunction Headlamp Switch
DOE factors for test matrix 1) Type of Lubricant
in the switch 2) Contact Material 3) Contact
Plating 4) Spring Pressure
The optimal combination was found and the design
was quickly changed. No field issues were found

Define the Basic Functions
  • Brainstorm a list of Basic Functions the Product
    must provide. What does this thing need to do?
  • Use Verbs
  • React
  • Position
  • Isolate
  • Filter
  • Rotate
  • Limit
  • Amplify
  • etc

30
Consider Classis Failure Mechanism that Cause
Failure Modes
  • Creep
  • Fracture
  • Yield
  • Physio-Chemical Instability
  • Dimensional Incompatibility
  • Contamination
  • Vibration and Mechanical Shock
  • Environmental
  • Wear

31
Consider Classis Failure Mechanism that Cause
Failure Modes
  • Creep (relaxation and flow over time, plastic
    movement, often accelerated with heat or high
    loads)
  • Fracture (brittle failure due to sudden physical
    overload, cracking)
  • Yield (Tensile or bending failure, permanent
    deformation)
  • Physio-Chemical Instability (Chemical change in
    material properties, Corrosion, UV instability,
    chemical attack of solvent or lubricants, heat
    aging of rubber)
  • Dimensional Incompatibility (Stack up of
    tolerances, mis-positioning, flexing of base or
    bracket, too big, too small)
  • Contamination (dirt, grit, dust, mixed materials)
  • Vibration and Mechanical Shock (mechanical or
    electrical high frequency, surge, sudden
    overload)
  • Environmental (hot, cold, humid, submersion)
  • Wear (repeated cyclic load causing material
    removal)

36
The Forward Pass
Likelihood of compromise of a Primary
Function due to a Sensitivity to Failure
Mechanism. Strong Likelihood Neutral
0 Not Sensitive
37
The Reverse Pass learn for what has happened
before

desired Functions

In this case, Contamination, Yield, Wear, and
Dimensional Incompatibility are the high
Occurrence Failure Mechanism that are anticipated
as the dominate Noise factors.

  • DOE
  • Partial Factorial Matrix experiment
  • Expert Knowledge, seek help in creation
  • Garbage in Garbage out (usually due to bad
    assumptions)
  • Want a simple lab fixture(s) to run a fast DOE to
    understand design sensitivity to Noise factors.
  • Run carefully Created samples to test for
    interactions

42
Basic Principles Friction, transient loads,
moments, unforeseen interactions, manufacturing
processes capabilities, marginally stable
systems, static electricity, grounding Wrong
Assumptions (independence of functions in switch
example)Lack of parts available on
timeComponents cost more than estimatedStack
up of tolerances reality is not design
nominalMurphys Law, Chaos Theory, probability
and statistical theory at workFalse or
unachievable accuracy
Causes of Problems
43
Idea GenerationDo not jump to conclusions or
select your mainstream concept too quickly.
Brainstorm, talk to experts, consider viability
of alternatives, carefully select your mainstream
direction based on Tradeoffs.ExecutionSet up a
good project plan with Milestones and Gate
ReviewsClearly defined Deliverables Set up a
budget (with a 10 contingency) and obtain good
cost estimates and availability of materials,
manpower, and facilitiesFront Load your efforts
get off to a good startAssign tasks to team
members based on skill sets and personal
preferences. Monitor progress, keep things
visible.Design and Build Modules where
practical.Use Standard parts and commonly
available materialsAllow time for
experimentation and Slack time for things to go
wrong in build test.Do your homework
