Chapter 10. Prototype Test Cycles

Question 1

Why prototyping is a Managerial Tool?

Answer 1

Feedback and learning
Communication and Information Sharing
Outside Evaluation
Establishing, Pacing and Monitoring the Development Schedule

Question 2

What kind of prototyping models Wheelrigth and Clark Present.

Answer 2

Standard Traditional
Revised Traditional
Periodic

Question 3

What kind of prototyping fits with the type of development project

Answer 3

Rapid response to Engineering—-Breakthrough
Integrated System Solutions or Periodic Prototyping—— Platform New Architecture
Replicate Manufacturing Early—-Incremental Projects

Question 4

Cost and Representativenessf Each Porotyping

Answer 4

CAD
Clay Model
Engineering Prototype
Pilot Production

Question 5

Issues and choices in prototyping: improving the traditional Model Through “Best Practice”

Answer 5

Evidence from a variety of industries suggest four “Best Practices” that apply to any firm and any prototyping cycle.
Low-Cost Prototypes: Simple industrial design models (form and shape), computer aided Engineering and simulation are less expensive It is necessary to make a better use of these classes of models and squeeze all its potential. Sometimes it is nesary to outsource some prototypes.
Prototyping Process Quality: Improve reliability and learning that occur in each prototype cycle. Avoid mistakes, (misreading a drawing, reversing and overlay, or failing to check a material before using it)
Timing and Sequence: When prototype cycles are overlapping people lost track of the progress of the project.
Building Knowledge. Continually improving the quality, speed and efficiency of the prototyping process, and strengthening prototyping’s repetitiveness and its ability to capture critical problem at each stage of the development.
Dimensions of Choice in Prototyping
Who build the prototype is a major issue during the life of the developing project, Everything is Synthetized in the Exhibit 10-6

Question 6

Types of Prototyping

Answer 6

Standard Traditional
Revised Traditional
Periodic

Driving Force: System Performance Cross Functional Integration

Responsibility for Building:

Early : Enginnering Model Shop
Middel: Manufacturing Production Line
Late :Commercial Production Line

Role of The uctomer
Early: Customer Test iof Prototypes
Late: Extensive Customer Field Test

Test Criteria

Product : Systeme Fucntionality
Process: System Functionality
