  1. Agenda for example 1. Customer requirements 2. Create concept 3. Define additional needs 4. Complete design 5. Define lower specs and I/Fs 6. Document design

  2. 1. Customer requirements • Problem statement • Customer requirements 1. Customer requirements

  3. Problem statement • Build a place to live for a family of four with an income of $80,000 per year • Build on speculation without specific customer in mind Applying the design process to a define a place to live is a good test for the design process because construction illustrates many aspects of design 1. Customer requirements

  4. Customer requirements • A place to live for a family of four • Costs less then $225,000 Customer requirements are the result of translating the customer problem into an agreement about the final product 1. Customer requirements

  5. 2. Create concept • Objective • Technique • Developing concept • Outputs of developing concept 2. Create concept

  6. Objective • Define the design sufficiently that we can estimate cost and manage project 2. Create concept

  7. Technique • Answers three questions • What are we going to build? • Can we build it? • Roughly how much will it cost to develop? • Zig-zag back and forth between asking what and then asking how 2. Create concept

  8. Developing concept (1 of 9) • Questions to determine what to build • Why are we building a place to live? • Profit of 20 percent • What general characteristics must the structure have? • Attractive to customers as determined by comparison to similar homes • Who is the customer? • A man, a wife, and two children Ask and answer high-level question to determine what to build 2. Create concept

  9. Developing concept (2 of 9) • Who is the user? • The family • What type of structure? • House • Apartment • Hotel • Recreational vehicle 2. Create concept

  10. Developing concept (3 of 9) house apartment rv hotel There are many possible solutions 2. Create concept

  11. Developing concept (4 of 9) house Using the process for creating a solution, choose a single solution 2. Create concept

  12. Developing concept (5 of 9) • Questions to determine if we can build the house and roughly what it will cost • How many square feet are in the house? • 2500 • How many stories? • Two • How many bedrooms? • 4 Ask and answer lower-level question to determine if we can build the house and roughly how much it will cost 2. Create concept

  13. Developing concept (6 of 9) • How many bathrooms? • 3 • Size of garage? • 2 cars • Bedroom locations? • Downstairs -- master plus one • Upstairs -- two 2. Create concept

  14. Developing concept (7 of 9) • Master bathroom? • Closet 1 -- 100 square feet • Closet 2 -- 30 square feet • Bathtub • Shower • Enclosed toilet • Garage-entry? • Rear entry • Utility room? • Yes 2. Create concept

  15. Developing concept (8 of 9) • Living areas? • Living room • Family room • Game room • Lot? • Dimensions • Orientations • Utility • Ally location • Existing landscape • Drainage 2. Create concept

  16. Developing concept (9 of 9) • Sink in utility room? • Yes • Storage under stairs? • Yes • Storage in attic? • 200 square feet, un-air-conditioned • Trim? • Crown-molding in formal areas • Appliances? • Middle-of-line, garage door opener 2. Create concept

  17. Outputs of concept (1 of 13) Generate design spec to capture answers to questions 2. Create concept

  18. Outputs of concept (2 of 13) 2. Create concept

  19. Outputs of concept (3 of 13) • Blueprint • Elevations • Lot plan • Plumbing drawing • Electrical drawing • HVAC drawing Create drawings to capture design 2. Create concept

  20. Outputs of concept (4 of 13) house lot lot prep found framing roofing plumbing HVAC electrical mason siding insul drywall trim painting cabinet flooring appl land fence clean up materials Identify lower products 2. Create concept

  21. Outputs of concept (5 of 13) • 1. Lot • 2. Lot preparation • 3. Foundation and concrete • 4. Framing • 5. Roofing and gutters • 6. Plumbing • 7. Heating, ventilation, and air conditioning (HVAC) 2. Create concept

  22. Outputs of concept (6 of 13) • 8. Electrical • 9. Masonry • 10. Siding • 11. Insulation and sound proofing • 12. Drywall • 13. Trim • 14. Painting and wall covering 2. Create concept

  23. Outputs of concept (7 of 13) • 15. Cabinetry and counter tops • 16. Flooring, tile, and glazing • 17. Appliances • 18. Landscape and sprinkling • 19. Fence • 20. Clean up • 21. Materials 2. Create concept

  24. Outputs of concept (8 of 13) Define dependencies 2. Create concept

  25. Outputs of concept (9 of N) • Plumbing • Below-foundation plumbing • Foundation • Above-foundation plumbing • Electrical • Below-foundation electrical • Foundation • Above-foundation electrical • Errors in dependencies can be worked around 2. Create concept

  26. Outputs of concept (10 of 13) • Schedule • Built up on basis of dependencies Define schedule 2. Create concept

  27. Outputs of concept (11 of 13) Define internal interfaces 2. Create concept

  28. Outputs of concept (12 of 13) • External interfaces • Sewage • Water • Gas • Electrical • Phone • Cable tv Define external interfaces 2. Create concept

  29. Outputs of concept (13 of 13) customer requirements STUDY high-level questions and solutions low-level questions and solutions drawings Capture studies and trace leading to design 2. Create concept

  30. 3. Define additional needs • Objective • Technique • Make product work • Meet requirements • Make usable and meet needs • Provide quality and affordability 3. Define additional needs

  31. Objective • Fill out all the details of the design such that the product can be built 3. Define additional needs
