Plot twist: they glued some libraries together in an afternoon and successfully replaced a system with several person-years of work in it. Actually 100x more effective dev. Double plot twist: after the 100x dev had left for greener pastures, nobody understands the system anymore and of course the initial afternoon of coding had no time for documentation or design reviews. The system has to be re-built and this time it will be built in-house with due attention to knowledge sharing and design documentation. Triple plot twist: Several years later someone realizes that the in-house system is overly complex and maintenance heavy, then replaces it with some glued-together open source libraries on a Friday afternoon. The cycle continues.
