Project time management is concerned with planning, managing, monitoring and evaluating the time needed and spent on project activities, in close relation to the progress planned and actually achieved.
Project time management develops from the WBS. Indeed, the work packages of the WBS are decomposed into activities, which are required to carry out the project.

The above process highlights the skills needed for Project Time Management: planning, setting goals and prioritising for better performance. Keeping track of the time schedule through reminders and alerts is required. A useful tool to schedule activities and track performance was developed by Henry Gantt (1910-1915) and is still used in various versions today.
The Gantt chart is a tool to help keep the project on track. It serves for scheduling the start and end dates (=the duration) of activities and tasks. Moreover, grouping together similar activities, offers a visualization of the activities’ sequencing over time. It is a common misconception that a Gannt chart is just a time-management tool, but it was developed to track production progress. As such, a Gantt chart helps follow the activity schedule but also the timely completion of the project’s sub-deliverables. In some chart versions, the name(s) of the team member(s) responsible for each activity is also stated on the chart.
Accordingly, the Gantt chart allows to:
Observe the following example of a Gantt Chart: activities, their duration and start date are listed on the vertical axis (e.g. Task A, Task B, etc.), while the calendar dates on the horizontal axis (weekdays). The duration of activities is visualised as red horizontal bars beginning at the start date and ending on the finish date scheduled for each activity. Note the sequencing of activities in the way the horizontal bars follow each other leaving no time-gaps. The allotment of time across the horizontal bar can follow the requirements of each project: it can follow a day-to-day categorisation (like the example here), a weekly, bi-weekly or even monthly time-allotment.
