The conventional wisdom that product lifetimes are shrinking has important implications for technology management and product planning. However, very limited empirical information on this topic is available. In this paper, product lifetimes are directly measured as the time between product introduction and withdrawal. Statistical analyses of desktop personal computer models introduced between 1...

Many recent books and articles stress that one key to long-term organizational health is a systematic process of new product design, development, and introduction. Innovation is accompanied by costs and risks, both of which can be controlled through a well-conceived program of new product development. A key ingredient in such a program should be the use of sound, explicit models for planning an...

In order to explore how Web search volume dynamically influences product sales during the whole product life cycle, this paper collects Web search volume and sales data of movies and does an empirical analysis using econometric models. The empirical results show that Web search volume before the launch of a new product has a positive impact on the product sales in the initial period of introduc...

Non-technological innovation is an important element of firms’ innovation activities that both supplement and complement technological innovation, i.e. the introduction of new products and new processes. We analyse the spread of nontechnological innovation in firms, their relation to technological innovation, and their effects to firm performance and success with product and process innovation,...

INTRODUCTION The COP820CJJCOP840CJ family of devices offer a broad range of features to meet the requirements of household appliances such as coffee machiness ironss shaverss and cleaners in addition to washing machiness dryerss and air conditioningg where the introduction of electronics helps to provide product differentiationn

BACKGROUND Recent declines in US cigarette smoking prevalence have coincided with increases in use of other tobacco products. Multiple product tobacco models can help assess the population health impacts associated with use of a wide range of tobacco products. METHODS AND FINDINGS We present a multi-state, dynamical systems population structure model that can be used to assess the effects of ...

This paper introduces a new method for the representation of knowledge that improves communication between engineer and object generation processes in the definition of product objects in modeling systems. New knowledge representations are introduced to improve knowledge representation capabilities of current product modeling systems to allow better understanding of product model, coordination ...

We introduce two new binary operations with combinatorial species; the arithmetic product and the modified arithmetic product. The arithmetic product gives combinatorial meaning to the product of Dirichlet series and to the Lambert series in the context of species. It allows us to introduce the notion of multiplicative species, a lifting to the combinatorial level of the classical notion of mul...

This paper examines the adoption of software product line engineering to implement digital differentiation of physical products. The introduction of such software-based variety can typically be challenging for firms innovating within the realm of a manufacturing paradigm. In particular, the mutual dependency between the organization design and product design of new product developing firms may ...

We study the strategic benefits of M&A when competing IT vendors sell different generations of the same product with different quality. We assume the new product arrives unexpectedly when an installed base of old product exists. We show that the combination of consumers’ purchase history and heterogeneity leads to new demand complexity that gives rise to innovative product strategies. We find t...
