Traditionally, when a school district adopts proprietary software for its core infrastructure, it can easily become locked into one solution or vendor, which greatly reduces choice and flexibility. Since educational policies, goals, and strategies change from time to time, flexible open infrastructure can better enable you to offer effective solutions and maintain control of your ecosystem without getting locked in. Rather than being limited by the features offered in a proprietary solution, licensed from a traditional vendor, a true open source offering allows institutions to freely access and modify the source code to create the system they really need; a solution that works well with other EdTech solutions within the overall existing ecosystem.
