Advantages of PSOP

• Better schedules: This is the big one! PSOP produces shorter schedules with less overload. Example and details
• Leveling by role: While P3e allows you to assign resources or roles to activities, it will only consider resources when leveling. PSOP allows you to level using resources, roles, or a combination of both. PSOP can even substitute primary roles for resources that have already been assigned. Example and details
• Splitting in-progress tasks: If a task is partially complete, the P3e leveler might separate the remaining work from the completed work. In many cases, this does not makes sense - once a task has started, you do not want it interrupted. The is no way to prevent P3e from doing this, short of adding constraints or mandatory dates to the in-progress activities. PSOP does not split in-progress tasks unless requested to do so. Example and details
• Honoring constraints: Primavera P3e ignores finish on or before and start on or before constraints when not leveling within total float. PSOP will honor these constraints unless instructed to ignore them. Example and details
• Handling unavoidable overload: If a task cannot be placed in a position that eliminates all of its overload, the P3e leveler will place the task at its early start. PSOP will instead place the task at the position that minimizes its overload. Example and details
• Correct handling of resource calendars: The P3e leveler does not correctly handle resource calendars and may schedule activities to work when the resources needed are not available. PSOP handles resource calendars correctly. Example and details
