Four boxes, one decision each
Complex and frequent tasks justify automation or a dedicated system. Simple and frequent tasks are the best candidates for templates or delegation. Simple and rare tasks should simply be done. Complex and rare tasks should be outsourced to a specialist.
Placing every recurring task in a box removes the vague guilt of 'I should systemise more' and replaces it with a short, ordered list.
Frequency beats complexity
A mildly complex task done daily costs more over a year than a very complex task done twice. If you only rank by difficulty, you will automate the wrong things.
The matrix weights both dimensions for this reason. Review it quarterly — a task's frequency changes as your business changes.
四个象限，各自一个决定
复杂且高频的任务值得自动化或建立专门系统。简单且高频的任务最适合模板化或交出去。简单且低频的直接做掉。复杂且低频的应当外包给专才。
把每件重复任务放进象限，能消除“我应该更系统化”这种模糊的负罪感，换成一份简短、有顺序的清单。
频率比复杂度更重要
一件中等复杂度、每天都做的事，一年下来的总成本高于一件极复杂、只做两次的事。如果只按难度排序，你会自动化错的东西。
矩阵因此对两个维度都加权考虑。每季度重看一次——随着业务变化，任务的频率也会变。
