Testing Expectations

System Model:

• Deterministic Model
  • Expected Pattern: Align tiles on floor, furniture only using the SmartScrew and minimize use of other tools
  • Expected Answer: Have the installer's installation process be quicker
• Stochastic Model:
  • Give SmartScrew prototype to 20 random construction crews
  • Give baseline tools to 20 other construction crews
  • Have the 40 random construction crews fix the floor using their respective tools
  • Find whether or not the construction crews that used the SmartScrew fixed their floors in less time than the households that used other tools to fix their floors
  • Also find out whether the crews that used the SmartScrew reduced their expenses to fix their floors over the households that did not use the SmartScrew to fix their floors

Process Model:

• Descriptive Model:
  • Actual Procedure:
    • Buy SmartScrew, or SmartScrew enabled deviced
    • Remove SmartScrew/Device from packaging
    • Use to align and level tiles during installation
    • Buyer's expense and installation time greatly reduced
• Prescriptive Model:
  • How process should be performed:
    • Use the SmartScrew to align, place, and level tiles and furniture
    • Minimize use of the other tools, such as drill, hammer, screwdriver etc.
    • Desired Outcome: Buyer's installation time and expense reduced
