Organizing for Product Organizing for Product DevelopmentDevelopment
Historically – distinct departments Duties and responsibilities are
defined Difficult to foster forward thinking
A Champion Product manager drives the product
through the product development system and related organizations

Organizing for Product Organizing for Product DevelopmentDevelopment
Team approach Cross functional – representatives
from all disciplines or functions Product development teams, design
for manufacturability teams, value engineering teams
Japanese “whole organization” approach No organizational divisions

Three common approaches to managing transition Project managers Product development teams Integrate product development and
manufacturing organizations
