Are some designs so good that they do not need to be changed?

3. Understanding Design Principles
An understanding of fundamental design principles, related to the decision-making process, provides the context for good design.
These principles may be well known to experienced designers, but may not be familiar to the general population.

4. Understanding Design Principles
They are not scientific principles, such as the laws of motion or thermodynamics, but are derived from practice or pragmatism.
They are the substance of professional engineering judgment.

5. Three Important Principles
All design begins with a clearly defined need. (Need)
All design arises from a creative response to a need. (Vision)
All designs result in a system, product or project that meets the need. (Delivery)

6. Need, Vision, and Delivery
New technologies create new processes.
The stability of a technological system is influenced by all of the components in the system, especially those in the feedback loop.
Research and development is a specific problem-solving approach that is used intensively in business and industry to prepare devices and systems for the marketplace.

7. The Design Process
The design process includes defining a problem, brainstorming, researching and generating ideas, identifying criteria and specifying constraints, exploring possibilities, selecting an approach, developing a design proposal, making a model or prototype, testing and evaluating the design using specifications, refining the design, creating or making it, and communicating processes and results.

8. The Design Process
Management is the process of planning, organizing, and controlling work.
Mathematics, creativity, logic, and originality are all needed to improve technology.
Technology usually affects society more directly than science because it solves practical problems and serves humans needs.
