Problem
An entrepreneur has identified a market for a device that can locate cattle.
The device needs to located all the cattle in a 100 square mile area.
The device can assume good weather The device must be capable of working when the
cattle are in rough terrain
10. Applications 10
Requirements
The device shall find 95 percent of all the cattle within a 100 square mile area within a continuous eight hour period assuming
The visibility is greater than 10 miles The humidity is less than 30 percent The terrain is that of Brewster County, Texas
The device shall display the location of each cow to the operator
10. Applications 11
Contractor Requirements
The contractor would like to make this device into a product line and sell to other customers, so the contractor imposes additional requirements
The device shall weigh less than 50 pounds. The device shall cost less than $10,000 in
production

Suggestions
Determining when to start Stabilizing the architecture Developing the staff and organization Understanding the customer Designing the product Developing the design concepts Looking at the big picture
10. Applications 15
Determining When to Start
Starting a product development depends upon Need of other products Available people Available money Schedule
10. Applications 16
Stabilizing the Architecture
It’s important to stabilize the architecture because the architecture influences
WBS Teams Staffing
A late change in fundamental architecture can cause rework

Management
A suggested priority for management objects is People, staffing, budget, and schedule Legal Risk, TPPs, and life cycle plan Facilities, tools, and capital Communication and library Systems for configuration, changes, issues,
problems, and action items Reviews

3. Simple products
10. Applications 21
4. Classical Development
Three phases are used to visual some programs Phase 0 develops a concept Phase 1 confirms ready for development Phase 2 develops the system
Concept exploration(phase 0)
Program definition & risk
reduction(phase 1)
Engineering & manufacturing development
(phase 2)

Series of PBDs
Phase 0 Phase 1 Phase 2
Classical development is a series of PBDs Nature of products varies with program
4. Classical development

14. State of Mind
The application of the PBD approach is a state of mind. It’s the ability to reduce clutter by treating a product as
a set of products and then being able to apply the PBD activities to each product.
