第二系统失败陷阱

Our experience with building a new LMS to replace an existing system provides at least one point of evidence that it is possible to avoid the SSE trap. The three principles that guided our design and planning for the new system (treat it like an MVP, look for abstractions that encompass both old and new features, and be sparing in how fully those abstractions are implemented) definitely contributed to the success of the project and are potentially ideas that could be applied in many situations where a system needs to be replaced.
