Chapter
Full-text available
This chapter shows the particularities of the Product Development System, with special emphasis to the Product Development Process (PDP). PDP itself is people-based, complex, and non-linear, with high ambiguity and uncertainty. Consequently, a wide spectrum of variables can affect its success, and, not surprisingly, over time, over budget and low q...
Chapter
A product development project normally has its genesis after a PD project is included in the company’s development portfolio, and the product vision is given to the chief engineer. This pulled vision puts the PD wheel in motion, triggering the identification activities (Fig. 10.1), which aim to deliver a comprehensive description of the development...
Chapter
This chapter describes the product development phases and activities, which are detailed in Chapters 10 to 13. We consider four phases in the PDP: (1) the portfolio phase, which produces a general vision of the product, both aligned to the value pulled by the market/customers and consistent with the company’s strategy and capacity; (2) the study ph...
Chapter

Chapter
This chapter discusses the evolution of product development approaches through time. It reviews the serial or sequential approach that was adopted by the companies under the influence of Industrial Revolution and Fordism. Then the Integrated Product Development (IPD) approach is presented and discussed. It’s worth mentioning that IPD was influenced...
Chapter
The opposite from value is waste. Waste absorbs resources, increase cost and create no value. Therefore the result from a wasteful activity is something that no one wants to pay for. Even though there is no Toyota definition of waste outside of the production process, the notion of waste helps to understand their development system. In fact, there...
Chapter
Planning (also called forethought) is the process of thinking about and organizing the activities required to achieve a desired goal. The planning activities define the value proposition delivery strategy, which aims to develop the scoped product in the most efficient way, with no/minimum waste, unevenness, or over burden. This chapter uses the sta...
Chapter
This chapter presents the main aspects related to organizational cultures which support the lean philosophy. Organizational culture is unique for every organization; it is not easily defined and even harder to change. It is essentially the cause and effect of the sum of all the written and unwritten rules, attitudes, behaviors, beliefs, and traditi...
Chapter
While the value identification activities were concerned about understanding and structuring all the value pulled by the stakeholders, the next step in the PDP aims to develop a possible functional architecture that can deliver this value, which is the chief engineer’s vision of the upcoming product/service. The value proposition documents in this...
Chapter
This chapter discusses how the continuous improvement acts like the motor that keeps the lean wheel running. As we stated in the previous chapters, while lean product development wheel goes toward its goal (the value to be delivered) all types of issues come on the way and might cause waste . Continuous improvement prevents a process from getting s...
Chapter
The term value is rather ambiguous, even in the product development field.

Chapter
Applying lean to the PDP takes IPD a step further to create Lean Product Design and Development (LDP). While LPD keeps the integrative aspect of IPD, the LPD is rooted in the lean philosophy, which advocates full commitment to delivering the pulled value (do the right), and yet continuously works on eliminating the waste from the PD process (do rig...
Chapter
Following the understanding of all the Lean Wheel System’s elements comes the moment to assemble your own wheel and start the lean journey by yourself.
