8. Identifying the Problem or Opportunity
Define the problem or opportunity.
Include criteria and constraints regarding appearance, operations, manufacturing, marketing, and finances.
Criteria focus on purpose and environmental, political, ethical, and social problems that may arise.
Constraints deal with size and cost.

10. Isolating, Refining, and Detailing
Using the criteria and constraints, the various solutions are examined to choose the best.
The final product must be safe, efficient, and functional.
Specifications and general characteristics are then established.

12. Communicating the Final Solution
Designers develop:
Detailed drawings with size, shape, and component arrangement.
Material lists, or a bill of materials.
Written and oral reports to gain approval to move on to production.
A specified solution is then ready for production.

13. Production Processes
Production processes grow and harvest crops, construct structures, and generate communication messages.
Each of the technological systems has its own unique production processes.
These processes move the solutions described by the design process into tangible solutions.
