The Spallation Neutron Source Project relies heavily on many different applications that require and depend on the SNS integrated relational database. Although many of the projects undertaken have been successful, the majority of time and energy spent on producing products has resulted in opportunities lost. The percentage of time lost or wasted has been very similar to that of software development projects everywhere. At the SNS the variety of factors that have influenced these projects can be traced to some specific areas: management support, project deadlines, user expectations, graphical user interfaces, and the database itself. This paper presents a look at the factors that have helped make different projects a success and factors that have led to less favorable results.

The Electrical Power Project consists of recording data on all power-distribution devices necessary to SNS operations and how they are connected, assigning a valid name to each device and describing it, along with loading this information and the relationships into the SNS Oracle database. Interactive web-based applications allow users to display and easily update power-related data. In the case of planned electrical outages, a complete list of affected devices (including beam-line devices) will be available to controls, diagnostics, and other groups in advance. The power-tree information can be used to help diagnose electrical problems of any specific device. Fast access to device characteristics and relations from any web browser will help technical personnel quickly identify hazards and prevent electrical accidents, thereby ensuring SNS electrical safety. The project was completed by a special task team containing individuals from different groups. The paper covers the project history, QA issues, technology used, and current status.
