2. Six Steps of Problem Solving And Engineering Design Process SVES Colleges of Engineering UML – ATP Lecture 2

3. Research the Problem Step One Research the Problem Gather all the information needed to consider this project Define the Problem Completion is realized with a project proposal

4. Define the Problem Step Two Define the Problem Study the problem and list as many facts as possible to fully define the problem Completing the design specifications Set Objectives Outcome is a set of specifications

5. Step Two Develop Design Specifications Define the Problem Specifications are a formal document listing the requirements of a project Define details that must be met Can be used as a guide in future projects Market Specifications

6. Develop Design Specifications & Specification Format General description Performance Power requirements Packaging Environmental Operation Project and production cost Agency approvals Special requirements

7. Develop Design Specifications Packaging Mechanical size limits Environmental rating Shape Material Human engineering aspects

8. Develop Design Specifications Environmental Ambient temperature Humidity Vibration Shock Electromagnetic interference (EMI) –Immunity –emissions

9. Develop Design Specifications Manufacturing Cost Goal Total cost of purchased parts Labor cost to manufacture Manufacturing overhead The projected costs should be stated at the volume of manufacture for the costs

10. Develop Design Specifications Software Outline of the planned method of software operation All operations that involve the end user All operations that involve the hardware Flow charts ( top level ) Flow charts ( sublevel operations )

11. Plan the Solution Step Three Plan the Solution Develop a Plan Outline Strategy List steps intended to solve the problem Outcome is a Project Schedule

12. Execute the Plan Step Four Execute the Plan Preliminary design Component selection Breadboarding Prototype development Outcome working Prototype

13. Verify the Results Step Five Verify the Results Test design to set design specifications Review measured results to specifications Does it meet the specifications ? Outcome is a reasonable solution to the problem

14. Develop a set of conclusions Step Six Develop a set of conclusions Results of the project are summarized Design improvements and performance monitoring Design documentation Outcome is a Final Report
