However, project managers are not required to rely on software to build the schedule. The benefit of building the schedule model this way is that the software can largely automate the creation of the finalized schedule, allowing the project managers to focus on communicating responsibilities with their team and facilitating the completion of the project and its subsequent tasks.

Some project managers feel the most efficient way to create and use a schedule model is with software programs with built-in analysis capabilities, such as Microsoft Project, Primavera, or Jira.
