Purpose of Prototyping
Four use of Prototype
Learning
Answering questions about the design
Focus on certain areas
New idea can be ventured during prototyping stage to enhance product performance
Communication
Demonstration of product for feedback
Ensure customer's needs are understood correctly
Test market demand
Plan production methods and costs
Integration
Combination of sub-systems into system model
Assemble electronic devices to the parts
Almost a complete version
Milestone
Goal for development team's schedule
Made quick to make decisions quickly
Reduce designs error before planning for production
Four types of Prototypes
Physical
Best used for market survey
Can use for function test
Analytical
A mathematical model of a product
To explore possibility as changes can be made very fast to see the result
Focus
Implemting one or a few attribute of product
Answers specific questions about the product design
Comprehensive
Often best for integration
Offer opportunities for rigorous testing
Difference of Prototype and Actual Product
It is not made from actual material
May not have all the features in the product
Shaped close to actual product but not economical use for mass production
Planning for a Prototype
Step 1: Define the Purpose
Step 2: Establish the level of approximation of the Prototype
How close should the prototype be to the final product?
Physical or analytical?
Step 3: Outline an Experiment Plan
Prototyping is experimenting
Ensure good & enough data are collected
Plan the experiment e.g define test protocol, measurement techniques, result analysis
Step 4: Create a schedule
Treat prototyping as a sub-project
apply project management skill, especially note the 'bucket pf parts' date, 'smoke test' date, final result date.
