Incentives in a Stage‐Gate Process

Many large organizations use a stage‐gate process to manage new product development projects. In a typical stage‐gate process project managers learn about potential ideas from research and exert effort in development while senior executives make intervening go/no‐go decisions. This decentralized decision making results in an agency problem because the idea quality in early stages is unknown to the executive and the project manager must exert unobservable development effort in later stages. In light of these challenges, how should the firm structure incentives to ensure that project managers reveal relevant information and invest the appropriate effort to create value? In this study, we develop a model of adverse selection in research and moral hazard in development with a go/no‐go decision at the intervening gate. Our results show that the principal's uncertainty regarding early‐stage idea quality—a term we refer to as idea risk—alters the effect of late‐stage development risk. The presence of idea risk can alter the incentives offered to the agent and may lead the principal to reject projects that otherwise seem favorable in terms of positive net present value. A simulation of early‐stage ideas, found through search on a complex landscape, shows that the firm can mitigate the negative effects of idea risk by encouraging breadth of search and high tolerance for failure.     

Citizens' Anti-highway Revolt in Post-Pinochet Chile: Catalyzing Innovation in Transport Planning

During the last third of the 20th century, citizens throughout North America and Europe organized protests against urban highway projects, influencing urban transport planning in ways that shape its evolution to this day. With the globalization of car-centred urban planning models, some similar movements have emerged in developing countries. What, if anything, can they tell us about citizens' role in innovation to achieve more socially just, good and livable cities? Using a multidisciplinary approach grounded in planning theory and a local adaptation of participatory action research methods, this study explores lessons from an anti-highway movement in Santiago, Chile (1997). This study contributes citizens' perspective on crucial issues within the philosophy and history of city planning, examining shifts in governance that can significantly influence the potential for change in planning and city systems, even under adverse conditions. Is improving participation just a matter of ‘getting the process right’? This experience indicates that it requires re-formulating frameworks to encompass democratization, fostering multi-scalar, self-generating civil society organizations, and focusing on the role of organized citizens, rather than individuals, as they act on policy ecologies. The evidence from this Santiago case supports Portugali's argument that planning is both a profession, exercised by especially trained ‘experts’, and a skill exercised by citizens working from their everyday expertise. This example explores the mechanisms through which, even in a relatively hostile environment, self-generated citizen organizations may play a significant role in contesting business-as-usual debates and achieving innovative policies favouring greater equality and sustainability.

组织冗余的利用对中国企业创新产出的影响

从冗余的控制权的角度将企业已吸收的冗余划分为分散冗余和组合冗余,分析了这两种冗余的利用对企业创新的影响,构建了一个包含冗余、吸收能力与创新之间关系的结构方程模型,并运用在607家企业进行的问卷调查所获取的数据实证检验了这个模型。结果显示,分散冗余和组合冗余分别与产品创新和过程创新存在显著的正相关关系,不同的冗余与不同的吸收能力之间存在一定的匹配关系,这种关系能够导致不同的创新产出。结果表明,中国企业的冗余与西方企业的冗余一样,都能够促进企业的创新产出,因此,广泛采用一刀切式的“减员”手段未必是中国企业“增效”的最有效率的策略。

Open innovation and quality management: the moderating role of interorganisational IT infrastructure and complementary learning styles

This study seeks to explain the influence of quality management on the relationship between open innovation and performance. We propose that, to contribute to open innovation performance, an organisation’s commitment to quality improvement must rely on the combination of its own resources and capabilities and its open innovation partners’ resources and capabilities. Specifically, we examine the moderating role of an interorganisational IT infrastructure and the complementarity of learning styles among an organisation committed to quality improvement and its supply network. Using data from 270 managers of European firms, our results show that the negative effects of quality management on open innovation performance can be overcome by complementing the organisation’s learning style with that of its open innovation partner, particularly, its supply network, and, most importantly, obtaining information technologies compatible with those of its supply network members.     

Effects of key enabling technologies for seru production on sustainable performance

Demand uncertainty, economic globalization, and environmental deterioration force factories to innovate their manufacturing systems for achieving sustainable performance. Seru production, which is the latest manufacturing mode developed in Japan, attracts broad attention from both academia and practitioners. The overwhelming majority of existing works on seru production focus on economic performance unilaterally, while neglecting the environmental and social performance. This paper investigates the effects of key enabling technologies for seru production on sustainable performance. Firstly, four key enabling technologies for seru production are identified through systematic review, and an evaluation indicator system of sustainable performance in the context of seru production is developed. Then, the hypotheses about the effects of the identified key enabling technologies for seru production on sustainable performance are proposed on the basis of previous research achievements, theoretical analysis, and practical observations. Finally, the hypotheses are tested through structural equation modeling. Except for two hypotheses which are not supported and one which is indirectly supported, all other hypotheses are verified. The research results show that the four key enabling technologies for seru production have different effects on the three dimensions of sustainable performance. The achievements of this work are of significance to improve the comprehensive understanding of seru production, as well as to develop practical methods to implement sustainable operations.
