## RIGOR Description
RIGOR is a Digital Checklist System that ensures verifiable compliance with standard procedures and produces reliable operations (i.e. predictable, safe, efficient operations based on best practices).  By applying RIGOR, procedures can be translated into aviation-quality checklists that can be executed with NASA precision.  The use of Notes, Cautions, and Warnings unites safety and operations at the time and place of task performance.  As checklists are executed, steps are time-stamped with who performed the action to provide accountability.   Additionally, user-entered performance data, captured images/videos, and time-to-complete are tracked and stored as part of every checklist record. This operational feedback is critical to reducing waste and variance and ensuring efficiency and quality goals are achieved and sustained. RIGOR provides all resources required to do the job right the first time – every time, making checklists the key to increased safety, efficiency, and reliability in your precision operations.
