Time
The work content identified by WBS is used as the basis for estimating the
approximate number of days required. The estimated number of days is
used to divide the schedule for each piece of work according to the
planned delivery dates in order to manage progress.
The schedule plan is determined based on the calculated number of operating days, clarifying the confirmation of progress, completion date, and
handover of each individual piece of work.
“Arrow diagrams” and “PERT ( Program Evaluation and Review
Technique ) ” charts are used to prepare the schedule plan. A “Gantt
chart” is used to illustrate the planned schedule.
Since there is a variety of work for each project, it is necessary to estimate
the number of days required for each piece of work.

Once the WBS is prepared, it becomes the foundation for all work areas
under PMBOK.
In addition, if any excesses or deficiencies are found in the WBS or while
the project is in progress, the scope is reviewed to ensure that it is always
up-to-date, and it is updated as any changes arise.
