Multiple opinions
Shared workload
Ability to accomplish more
A chance for leadership and personal satisfaction

What are the six steps to the Design Process?
1) Define the Problem
2) Generate Concepts
3) Develop a Solution
4) Construct and test a prototype
5) Evaluate Solution

What should a design brief include?
Locker Organizer Design Brief Example
Client: John Q. Public
Designer: Jane P. Smith
Problem Statement: My school locker is a mess. I can never find a pen, pencil or calculator. My homework is always getting lost, and my lunch gets crushed under a sea of books and binders. Because of the clutter, it is hard to close my locker door completely.
Design Statement: Design, model and test a high school locker organization system that will neatly contain items commonly used and kept in school.
Constraints:
-2-week design/build time period
-$40 maximum cost
-8 in. x 8 in. x 48 in. inside locker space
-No flammable materials
-Easy to install
Deliverables:
Initial sketches
3D CAD models/assemblies
Technical drawings
Project design journal
Prototype
Summary presentation
Agriculture
The raising of crops and animals for food, fiber, fuel, or other useful products
Artifact
A human made object
Biotechnology
All of the technology connected with plant and animal life
Communication
The transmission of information through a common system of symbols, signs, behavior, speech, writing, or signals.
Construction
The act or process of building erecting, or constructing buildings, roads, or other structures.
Energy
The ability to do work. Energy is one of the basic resources used by a technological system.
Engineering
Using technological and scientific knowledge to solve practical problems.
Environment
The surroundings in which a person, animal, or plant lives.
Ergonomics
The study of workplace equipment design or how to arrange and design devices, machines, or workplace so that people and things interact safely and most efficiently.
Industrial
Of, relating to, or resulting from industry.
Innovation
An improvement of an existing technological product, system or method of doing something.
Invention
An new product, system, or process that has never existed before, created by study and experimentation.
Manufacturing
The process of making raw material into a finished product; especially in large quantities
Math
The science of patterns and order and the study of measurement, properties, and the relationships of quantities using numbers and symbols.
Nanotechnology
The science and technology of building devices, such as electronic circuits, from single atoms and molecules.
Process
Human activities used to create, invent, design, transform, produce, control, maintain, and use products or systems; a sequence of actions that combines resources to produces an output.
Science
The study of our natural world through observation, identification, and theoretical explanations.
System
A group of interacting interrelated, or independent elements of parts that function together as a whole to accomplish a goal.
Technology
The way people use resources to meet their wants and needs
Transportation
The process by which passengers or goods are moved or delivered from one place to another.
Aesthetics
Pleasing in appearance
Brainstorming
A method of shared problem solving in which all members of a group spontaneously, and in a n unrestrained discussion, generate ideas.
Constraints
A limit to the design process. Constraints may be things like appearance, funding, space, materials, and human capabilities.
Consumer
A person or household that purchases goods or services.
Criteria
Desired specifications (elements or features) of a product or system.
Decision Matrix
A tool for systematically ranking alternatives according to a set of criteria.
Design
An iterative decision-making process that produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems
Design Brief
A written plan that identifies a problem to be solved, its criteria, and its constraints. The design brief is used to encourage thinking of all aspects of a problem before attempting a solution.
Design Elements
The factors (e.g., line, color, light, shadow, space, texture) that define a product and take into account the aesthetics and function of the product.
Design Process
A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve a problem or satisfy human needs and wants and to winnow (narrow) down the possible solutions to one final choice.
Designer
A person who designs any of a variety of things.
Dimension
A measure in one direction.
Evaluate
To form an idea of the amount or value of; assess.
Experimentation
The act of trying out a new procedure, idea, or activity.
Exponentially
Extremely rapid increase.
Investigate
To observe or study by close examination and systematic inquiry.
Model
A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. A model is often used to test ideas, make changes to a design, and to lean more about what would happen to a similar, real object.
Modify
Change to assure accuracy
Optimize
An act, process, or methodology used to make a design or system as effective or functional as possible within the given criteria and constraints.
Problem Solving
The proves of understanding a problem, devising a plan, carrying out the plan, and evaluating the plan in order to solve a problem or meet a need or want.
Prototype
A full-scale working model used to test a design concept by making actual observations and necessary adjustments
Requirements
The parameters placed on the development of a product or system. The requirements include the safety needs, the physical laws that will limit the development of an idea, the available resources, the cultural norms, and the use of criteria and constraints.

Systematic, scientific, documented study.
Specification
A detailed description of the design and materials used to make something,

A method for collecting data.
Texture
The feel, appearance, or consistency of a surface, substance, or fabric
Trade-off
An exchange of one thing in return for another; especially relinquishment of one benefit or advantage for another regarded as more desirable
Visualization
Formation of mental images
How do engineers communicate between each other
By reading their engineering notebooks. Also things like design matrixes.
