AbstractTo improve overall operational efficiency, a formal requirements management program has been initiated at the Pacific Northwest National Laboratory1. The goal of this program is to develop a robust, dynamic, integrated, informative decision base, for Laboratory‐wide use instead of the more typical assemblage and maintenance of many specific “product line” or “product” requirements.The external requirement documents that regulate the Laboratory's activities include U.S. Department of Energy (DOE) Orders, Code of Federal Regulations, State of Washington regulations, industry standards, Tribal and local government consent agreements, contracts, city and county ordinances, other Federal interagency agreements, and Battelle Memorial Institute policies. When these documents get updated or revised, these changes can affect the Laboratory's work.The current estimate is that hundreds of external requirements documents yield thousands of individual external requirements. These documents also have a high degree of variability in format and content, both in a particular document and between document types. Given the large number and scope of issues encompassed by these requirements, our review found that the “historical situation” (i.e., information distributed from personal computers, lists, manuals, procedures, correspondence, and personal memory) was no longer sufficient. No unified requirements analysis set identified all of the individual, applicable external requirements in readily retrievable form, nor were the external requirements linked to the systems to which they apply.Similar external requirement document integration efforts by other organizations have produced work that is obsolete by the time they publish it, because of the failure to address the dynamic nature of the external requirements documents. This report describes an automation tool (“System Level Automation Tool for Engineers” [SLATE]) that we use to support requirements analysis and the ongoing management of requirements. Experience with this tool as a key element of requirements analysis and management in a timely, cost‐effective, Laboratory‐wide manner is discussed.Pacific Northwest National Laboratory is operated by Battelle Memorial Institute for the U.S. Department of Energy under Contract DE‐AC06‐76RLO 1830.
