Innovators at NASA's Johnson Space Center have developed a comprehensive change request management tool with built-in workflow processes to track the thousands of activities, tasks, and condition-related information for the International Space Station (ISS) mission plan. The Planning Products Change Request (PPCR) application is the primary tool used by all ISS control centers globally to track and approve all changes to the ISS mission plan. The tool takes each PPCR submitted, which can include multiple changes, and makes the appropriate assignments to the mission day and time to which the change applies. This allows planners to view a summary of all the changes for any one mission day, even though changes were received via multiple PPCRs and from various other flight controllers and disciplines. Plan changes in each PPCR are implemented into the Onboard Short Term Plan View and/or the Consolidated Planning System applications that contain the formal mission schedules.


  • Efficient: Performs detailed management of highly configuration-controlled mission plans
  • Streamlined: Provides constant workflow and approval process feedback to all users
  • Web-based: Permits easy access from all control centers
  • Comprehensive: Keeps global flight control teams and planners in synch with schedule changes


  • Complex space operations with environments similar to the ISS
  • Hospitals with multiple surgical/operating rooms to staff and maintain
  • Manufacturing facilities processing multiple products on the same manufacturing line
  • Chemical plants manufacturing several different or specialized products
  • Airlines that manage a large number of resources and schedules including schedules for flight crews, flight hardware, catering supplies, fuel, luggage, and maintenance equipment and personnel
