Understanding fire fighting in new product development⋆
本文建立了一个多项目开发环境下的救火行为正式模型，发现救火会自我强化，且多项目系统比预想更容易陷入这种低效循环，对资源与产品组合规划方法提出了警示。
Despite documented benefits, the processes described in the new product development literature often prove difficult to follow in practice. A principal source of such difficulties is the phenomenon of fire fighting‐the unplanned allocation of resources to fix problems discovered late in a product's development cycle. While it has been widely criticized, fire fighting is a common occurrence in many product development organizations. To understand both its existence and persistence, in this article I develop a formal model of fire fighting in a multiproject development environment. The major contributions of this analysis are to suggest that: (1) fire fighting can be a self‐reinforeing phenomenon; and (2) multiproject development systems are far more susceptible to this dynamic than is currently appreciated. These insights suggest that many of the current methods for aggregate resource and product portfolio planning, while necessary, are not sufficient to prevent fire fighting and the consequent low performance.
