“5W2H”原则可以使工作和任务设计更加完善，防止遗漏，使设计的结果更有效。具体如下：
WHAT---什么事？要做什么？（明确工作/任务的内容） WHO---由谁来执行、谁来负责？（明确工作/任务的对象） WHEN---什么时候开始？什么时候结束？什么时候检查？（明确工作/任务的时间表）
WHERE---在哪里做，哪里开始？哪里结束？（明确工作/任务的空间位置和变化）
WHY---这样做的必要性是什么？有没有更好的办法？告诉下级
事情的重要性可以使其更负责任！或受到激励。（明确任务的目的）
HOW---如何做？应该用什么方法做？（工作/任务完成的程序/方法设计）
HOW MUCH---做多少？做到什么程度为好？（明确工作/任务的问题与解决）
5W2H is the principle that can help you complete your job and task design,
avoid omission and make your plan more efficient. The details are as follows: What—What’s the job? And what to do? (to make clear the content of job/assignment )
Who---Who will do it? And who will be responsible for it? （to make clear the object of job/assignment ）
When---When to begin? When will be finished? When to check it? (to make clear the schedule of job/assignment)
Where---Where to do? Where to begin? Where will be finished? (to make clear the location and variation of job/assignment)
Why---Why it is a must to do so? Which method is better? Tell your team the necessity to ensure their responsibility! Or inspire them! (to make clear the target of job/assignment)
How---How to do it? Which measure should be taken? (to make clear the procedure/plan of job/assignment)
How much---How large the job is? To which extent is suitable? (to make clear the problem and solution of job/assignment)
