Project Information

Project Start Date – The project start date specifies the first day of the first task. Tasks are automatically scheduled from or after this date.

Current Date – This setting specifies the current date. It is used in place of the status date for the complete-through date in the Update Project dialog box if the current date is later than the status date, or the status date is set to NA.

From Start/From Finish – This option designates how a project is scheduled. When scheduled from start, the following is true:

n  The project’s finish date is calculated.

n  Delay values are positive and applied at the start of a task.

n  ALAP tasks ignore any Leveling Delay values as the task is already as late as possible.

n  Calculations are conducted as follows:

·  For MSO and SNLT tasks: [LF] = [LS] + Duration

·  For the predecessor task of an (SS) link: [LF] = [LS] + Duration

·  On the forward pass (done first because we are scheduled from start):

·  [EF] = [ES] + span of task + task leveling delay.

·  [SS] = [ES] + task leveling delay.

·  [SF] = [SS] + span of task.

·  On the backwards pass:

·  [LS] = [LF] – span of task

·  Predecessor [LF] = successor [LS] – successor task leveling delay (if finish is linked)

·  Predecessor [LS] = successor [LS] – successor task leveling delay  (if start is linked)

When a project is scheduled from finish, the following are true:

n  The project’s start date is calculated.

n  Delay values are negative and applied at the finish of a task.

n  ASAP tasks ignore any Leveling Delay values as the task is already as soon as possible.

n  Calculations are conducted as follows:

·  For MFO and FNET tasks: [ES] = [EF] – Duration

·  For a successor task of an (FF) link: [ES] = [EF] + Duration

·  On the backward pass (done first because we scheduled from finish):

·  [LS] = [LF] – span of task + task leveling delay

·  [SF] = [LF] + task leveling delay

·  [SS] = [SF] – span of task.

·  On the forward pass:

·  [EF] = [ES] + span of task

·  Successor [ES] = predecessor [EF] – predecessor task leveling delay (if start is linked)

·  Successor [EF] = predecessor [EF] – predecessor task leveling delay (if finish is linked)

Priority – Priority sets the leveling order of importance for the project as a whole. It is used when using a resource pool or leveling a project with inserted projects. Priority may be set from 0 to 1000 with 1000 being the higher priority.

Status Date - Microsoft Project uses the status date to identify the complete-through date in the Update Project dialog box unless it is earlier than the current date setting. If you set the status date to NA, Microsoft Project uses the current date as the status date.

Project Settings

Calculation Option – Setting this option to automatic specifies that you want your project automatically recalculated when information within your project changes. Setting this option to manual allows you to choose when to recalculate the information within your project.

Show Scheduling Messages – Enabling this option displays warnings regarding problems with your project’s schedule. If this option is disabled, you will not be alerted to potential problems with your schedule.

Auto Link inserted or moved Tasks – Select the Auto link inserted or moved tasks check box to automatically re-link tasks when you cut, move, or insert them. If you clear this check box, Microsoft Project does not create any task dependencies when you cut, move, or insert tasks. This option only works for FS relationships. This is a local setting saved with the active project.
