BAT is a Web-based application used for the assembly and inspection of critical flight and associated ground support hardware for JPL missions that are developed in-house. It is used to capture and communicate data that is unique to a part or assembly that cannot be captured in an engineering drawing or a test procedure. It includes a list of parts and tools, along with specific steps required for building and assembling a piece of hardware.

In order to leverage expertise and technology development from previous missions, it is necessary to find and reuse complete build instructions. In the effort to create a fully electronic and searchable build book, the data needed to be captured electronically. The BAT application was designed to improve efficiency, reliability, and quality of the end-to-end process and reduce communications overhead.

The BAT application has a workflow that supports and enforces the assembly and inspection processes. The application helps users collaborate on creating and editing records. BAT validates part information and links to multiple systems for better data integration and easy access to relevant material. The application captures electronic signatures of the Engineering and Quality Assurance team and keeps a change log. It has a customized user inbox for easy access to records. BAT captures fabrication, assembly, and test steps electronically. Users are able to create, edit, or bring over existing rich text, images, and tables into the Web application. Users are able to duplicate, move, or delete one or more steps, and the system will re-number the steps based on business processes and the step type of inspection.

The BAT system is built on an extensible, integrated, and flexible infrastructure that makes the data in the system more reliable and valuable. The state of hardware is more visible to all users. Audits of the build-assemble-test process are significantly less resource-intensive.

BAT is fast, easy to use, robust, and flexible. Other software applications typically require download of software and significant training vs. BAT, which provides a Web-based application.
