Why Teams are important
•
What is a Team
Introduction
•
Engineering schools requiring students work in teams• Collaborative study groups
• Laboratory groups
• Design groups
as part of individual classes
participating in extracurricular competitions
Corporations Use Teams
• Engineers asked to solve complex problems
• More factors in design and production than ever before
• Teams understand more through collaboration / varied expertise
• Many corporations are global, operations spread all around
• Concurrent engineering widely employed
due to time to market changes
Engineer Design Factors
•
Initial Price•
Life Cycle Costs•
Performance•
Aesthetics•
Overall Quality•
Ergonomics•
Reliability•
Maintainability•
Manufacturability•
Environmental Factors•
Safety•
Liability•
World MarketInternational Factor
•
Many corporations are international in scope•
Requires communication and sharing dataelectronically
•
Teams may never physically meet• At any point in a 24-hour
Speed…
•
Timely delivery of products to marketplace•
Critical for profits•
Do not compromise quality to meet demands•
“We have seen what wins in our marketplaces around the globe: speed, speed, and morespeed.”
Jack Welch - Former CEO of GE
•
“Reduce product development time to 1/3, and you will triple profits and growth.”Group vs Team
Group
•
Individuals with a
shared interest or
task
Team
•
Working together
to achieve a
common purpose
when this can not
be accomplished
by an individual
A Team IS NOT the same as a Group!!!
Teams
•
Purpose
• Its task at hand, reason it was formed
•
Collective style is how the members
worked together
• Each has own style, approach, dynamic, and ways of communication
To be Successful …
•
Common goal or purpose•
Leadership• Every member contributes
•
Each member makes unique contributions•
Effective team communication• Effective meetings, honest and open discussion
Attributes to be a Success
•
Attendance• Attends all meetings on time (Dependable)
•
Responsible• Accepts and completes tasks on time
•
Abilities• Meets team’s needs fully for the purpose
•
Creative and Energetic• Is excited and has a positive attitude
•
PersonalityGrowth Stages of a Team
•
Teams require nurturing
•
Must pass through several
development stages before becoming
successful
Stage 1: Forming
•
Team members become acquainted with• One another
• The Leader
Or they choose • Team’s Purpose
• Overall level of commitment (workload) required
Stage 2: Storming
•
Enormity and complexity of task sinks
in
• May discourage
•
One person doing ALL the work is
FAILURE
Stage 3: Norming
•
Members begin to accept one another
instead of complaining
•
Shared expectations or rules among
the team
•
Feelings of closeness,
Stage 4: Performing
•
Teams accomplish a great deal•
Responsibilities distributed and executed individuallyStage 5: Adjourning
•
Team disbands•
Accomplished goals•
Successful teamsmay feel euphoric

Engineering Design
•
Learning Objectives
• Know the elements of the engineering design process
• Understand that all designs involve
constraints, limitations, and trade-offs
What Is Engineering Design?
•
“Engineering Design is the process ofdesigning a system,
component, or process to meet a desired
Significant Factors
• Functionality
• Does it work, does it meet the need
• Quality
• How well ,for how long
• Safety
• End user and in production
• Ergonomics
• Ease of use
• Appearance
• Appealing to the user
• Environmental Considerations
• Production, end of life
• Economics
Design Process
Need / opportunity
Problem Definition / Specifications
Data & Info collection
Development of alternatives
Evaluation /
Need / Opportunity
•
Establish the Need (opportunity)•
Identify information sources to understand problem’s scope and nature•
Investigate issues and background• Who are the customers
• Are there existing solutions
• Are there constraints
Problem Definition / Specifications
•
Develop apreliminary, formal problem statement
•
Establishpreliminary goals
•
Determine workingcriteria
•
Example Working Criteria Questions• Costs?
• Production Difficulty?
• Size, Weight, Strength?
• Appearance?
• Ease of Use?
• Safe to Use?
• Legality Concerns?
Data & Information Collection
•
For each of the criteria established, collect sufficient data to address•
More detailed investigation of impact of the solution (is there a market? at what price?)•
Identify other resources (people, equipment,knowledge) needed
•
Organization is key Problem Definition / SpecificationsDevelopment of Alternatives
•
Always more than one solution - develop as many creative solutions to the problemaddressed as possible. Brainstorm
•
Consider all ideas• “Dumb” ideas may lead to the final solution!
•
Generated ideas narrowed to few ideas•
Clarify ideas – always keep in mind “whatEvaluation of Alternatives
•
Remaining ideasanalyzed thoroughly and accurately
•
3 to 5 optionsshould remain after analysis
•
May have to start process over•
Analyzing Possibilities• Common Sense
• Economic Analysis
• Estimation
• Computer Analysis Techniques
• Modeling / prototype
• Conservative Assumptions Development of
alternatives
Select Design
•
Formal presentation of design
information
• Detailed written reports
• Design specifications
• Final drawings
Implement
•
Design Team may hand-off project to manufacturing / production team•
Product built•
Delivered to customer / put in useOne of the joys of engineering is seeing
Your Turn
•
The objective of this activity is to design
a free-standing prototype structure to
capture and contain a golf ball sized
object from a 6 foot free fall. The
Your Turn
Your Turn
•
Consider the design process
• Write (in your own words) the problem statement
• Try to think of existing solutions
• Try and come up with 2 – 3 alternative
Your Turn
•
Constraints
• The materials you have to make the
structure are 2 pieces of paper, 6 inches of tape and 1 rubber band
• Teams (so you have to be willing to
share ideas !!)
• You have 25 minutes to design and
Your Turn (You’ll Need a Team)
Requirements
•
In your own words a description of the problem you are solving•
List generated during brainstorming•
“Detailed” sketch and description of final design•
Written description of why you chose that designYour Turn
•
We will test the prototypes
Good luck
