  1. Product Design and Development Chapter 1 & 2 Development Process and Organization

  2. Product PRODUCT- any device or system that is designed and produced for use by a customer Customer-Person who ultimately buys the product • Another person in your company who may use the device you design • Think broadly about who the customer is (who does the product affect) • Chief objective of product design - Satisfying the customer(s)

  3. Why Study the Design Process? • Continuous need for new, cost effective, high quality products • Today’s products are complex and require a team of people with different backgrounds to take an idea from concept to market • ~85% of problems with new products not working as intended, taking too long to bring to market, or costing too much are the result of a poor design process

  4. Measurement of the design process • Product Quality – How good is the product • Product Cost – What is the manufacturing cost • Development Time – How quickly was the product developed • Development Cost – How much was spent to develop the product • Development Capability – can the team be better able to develop future products

  5. 3 measures of design Cost Time Quality Duration may vary from 1 yr to 10yrs or greater (Exhibit 1-3, pg 5)

  6. Design and Development Team • Marketing • Design • Mechanical • Electrical • Software • Industrial • Manufacturing • Operations • Warehouse • Supply Chain

  7. Development and Design Process • Phase 0: Planning – Begins with the strategy and assessment of technology developments and market objectives • Phase 1: Concept Development – Identify target market, alternative product concepts generated and evaluated • Phase 2: System-level Design – Definition of the product and break-down into subsystems and components

  8. Development and Design Process • Phase 3: Detail Design – Complete specification of the geometry, material, tolerances and manufacturing details • Phase 4: Testing and refinement – Prototype evaluation and assembly testing. Utilizes prototype tooling • Phase 5: Production Ramp-up – Completion of production tools and process to implement manufacturing process as well as train workforce (work out the kinks) Exhibit 2-2 pg 14

  9. Development Steps • Step #1: Identify Need • Two sources: the market (market-pull), or the development of a new technology (technology push) •  Step#2: Plan for the Design Process • Planning involves simply deciding on how to allocate the company’s resources of people, money, time, and equipment to complete the design tasks. • Step #3: Develop Engineering Specification • Goal is to completely understand the problem • Three steps: • 1)identify customers • 2) generate customer requirements • 3)develop engineering specifications • Step #4: Develop Concepts • Based on customer requirements and engineering specs. • Multiple concepts may be evaluated by comparing the concepts generated to the specifications developed. Goal is to select the best concepts for refinement into products. • Step #5: Develop Product • Starting a project with a single conceptual design in mind, without concern for the earlier phases, is poor design practice and leads to poor-quality products. • As products are developed, the are evaluated for manufacture, assembly, behavior, and cost.

  10. Development Steps (cont) •  During each stage of the design process, we must be able to communicate the information to others (recall concurrent design). • Design Notebook • Communication with management/customers (possibly during design reviews) • Make it understandable to the recipient. • Carefully consider the order of presentation: • Present the whole concept or assembly and explain its function • Describe the major parts and how they relate to the whole and its function • Tie the parts together into the whole • Be prepared with quality material: • Have good visual aids and written documentation • Follow an agenda • Be ready for questions beyond the material presented • Documents communicating the final design • Drawings (or computer data) of assemblies and details. • Written documentation to guide manufacture, assembly, inspection, installation, maintenance, retirement, and quality control.

  11. Product Development Organizations • Exhibit 2-8 pg 29
