Making plan and dividing huge system

Making plan is similar to designing software architecture in certain parts. Making plan is a usual task a project manager has to do. Certain thoughts and methods which are widely used for designing software architecture could be used for making plan.

For example, the abstract method is efficiently used by developers to divide huge system. The developers use different levels of abstract to divide entire system into different grading of pieces. As similar, we also use different grading to divide entire task into smaller tasks.

Specifically, if the entire task lasts one year. Firstly, we can use one month as the grading to divide the entire into twelve subtasks. Each subtask lasts one month. Secondly, we use one week as he grading to divide each one month lasted task into four subtasks which one lasts one week. If in demand, we can repeat the dividing by smaller grading like one day or one hour.

Management and computer science have more common point. Management is formulating rules and let humans to execute them. And computer science is formulating rules and let machines to execute them. Humans and machine both are natural, they have the same bases.
