Just-in-Time (JIT) processing is used in some manufacturing in order to optimize the overall system and maintain efficiency in supply and materials. While schools are not production facilities, there may be elements of these systems that can be incorporated into technology for dynamic school day scheduling. The software and processes involved take into account a huge variety of factors and help predict the most appropriate and efficient pathways. JIT systems may also incorporate Advanced Planning and Scheduling software, which may also have relevant programming technologies for school day scheduling.
