Terms
Aesthetics
the use of form, dimensions, colors and materials to make a product visually attractive.
uses anthropometric data to design and arrange products and services so that people will interact with them in a healthy, comfortable. and efficient manner.
Ergonomics (human Factors)
Ing
any task required to create, deign, manufacture, servie or dispose of a product. A PRODUCT IS NOT THE SUM OF ITS PARTS ALONE BUT OF THE WHOLE PROCESS
prototype
early sample, model, or release of a product built to test a concept or process
Trade off Deciscions
The ranked list of illities allows us to make good tradeoff decisions
Anthropometrics
The study of the human body and its movement and collecting statistics or measurements relevant to the human body.
The cost of changes escalates as you leave the concept phase, add details, and lose flexibility
Escalator Effect
Marketing Brief
a document created for the salespeople with a description of the product and its purpose and use.
Scope Creep
Changes to features or functions that expand the original goals of a project while it is in progress.
1.the discovery of an important requirement, opportunity that had been missed
2. changes in response to an external event, such as in the competition, regulations or environment.
Visual prototype
Mile 2. an accurate representation of the appearance pr aesthetic concept.
Boundary
A constraint on the design due to various factors including time, special customer requirements, regulations, or competition.
Failure mode and effects analysis. Take actions to eliminate or reduce failures starting with the highest - priority ones.
FMEA
Pareto Principle
specifies an unequal relationship between inputs and outputs. aka. the 80/20 rule
Seven Evil Families of Ing
1. Variation
2. prescion
3. complex architecture
4. Sensitivity
5. Immaturity
6. Environmental Requirements
7. Skill Intensity
Biggest drivers of hidden cost and poor quality.
Concept phase
Try to stay in this stage as long as possible, because it is the cheapest and most flexible time to make design decisions before they get fixed in prototypes
No new features and/or functions - the product will be taken to market as is. This is mile 3.
Feature Freeze (functional prototype)
Pilot Priniciple
Mile 5. The first run coming of the assembly line; basically, a test of the production system.
Specification
A written statement of the required characteristics of a product or process, to define its procurement or production and acceptance
Design quadrant (global view)
The four areas - customers, suppliers, shop, design - that are affected by design choices. Design Erosion occurs when one quadrant is overemphasized.
1. are the positive attributes of a design
2. the causes for illities
3. the bridge from strategy to design, and suggest actual materials and processes
1. Illities
2. Drivers
3. Tactics
Project Definition
Mile 1. The written specifications/descriptions of the design project.
Standard
document that provides guidelines for a product or process to establish acceptable levels of quality and safety
