One of the major causes of failure of information system design is the failure of developers to take into account the organizational environment, thereby leading to an unusable system. The first step in designing an effective system is to describe the user's view of the system, a view that incorporates how the system will help users to manage information in their particular organizational environment. For nurses involved in designing a nursing information system, a useful way of considering the organizational environment is provided by Perrow. The organizational technologies described by Perrow can be viewed as different models of nursing practice, each with particular requirements for a knowledge base and a data base. Nurses can identify the model that most closely corresponds to actual or desired nursing practice in their agencies and use the model's associated knowledge base and data base requirements as a guide to specifying the information system to be developed.
信息系统设计失败的主要原因之一是开发者未能考虑组织环境，从而导致系统无法使用。设计有效系统的第一步是描述用户对系统的看法，这种看法包含了系统将如何帮助用户在其特定的组织环境中管理信息。对于参与设计护理信息系统的护士来说，佩罗提供了一种考虑组织环境的有用方法。佩罗所描述的组织技术可以被视为不同的护理实践模式，每种模式对知识库和数据库都有特定要求。护士可以识别出与他们所在机构实际的或期望的护理实践最相符的模式，并将该模式相关的知识库和数据库要求用作指定要开发的信息系统的指南。
