Activity Calendars, Start and Finish Dates
Activity type, duration type, and percent complete type.
WBS element and Activity codes
Constraints
Expenses
Predecessor and successor relationships
Work Products and deliverables

Steps

•To Add Activities, Click on Activities in the Home page or Project>Activities 

•Organize Layout based on WBS & SORT by Activity ID 

•Add Activities to respective WBS Level by clicking on ADD on command Bar button 

There are 6 types of Activity Types

 1.Task Dependent –> In a fixed duration

 This is the default activity type in P6.

 2.Resource Dependent

 3.Level of Effort

 4.Start Milestone

 5.Finish Milestone

 6.WBS summary

Activity Steps 

Steps allow you to break activities into smaller units and track the completion of those units.

Activity % Complete type 

The way in which the percent complete for the selected activity is determined 

There are 3 types in this 

Duration Type 

Physical Type 

Units Type

Relationships 

A Relationship defines how a Activity relates to the start or finish of another activity. These Relationships form a logic to your project and are used together for determining Schedule dates.

 Relationship Types

Finish to Start (Default)

Finish to Finish

Start to Start

Start to Finish

How to Assign Relationships?

•Select an Activity and select its successor from “successor” tab in the activity detail form

•Activity details can be enabled from the list of tool bars shown on the top of the layout.

Assigning Calendars and Activity codes

• To Assign Calendars/activity code select the activity and enable activity details 
• In Activity details click  on General/Codes Tab 
• Click on Assign and select the respective calendar/codes.

Scheduling 

Scheduling can be done in two ways 

When you choose the schedule command or each time you make a change that affect schedule dates.

The Critical Path Method (CPM) scheduling technique is used to calculate project schedules. CPM uses activity durations and relationships between activities to calculate the project schedule

How to Schedule? 

•To Schedule the project press F9 key.

•Select the data date and click on schedule command
•P6 Schedules the project on CPM and Critical path activities will be displaced in red color
•P6 Calculates early dates during Forward pass and Late Dates during Backward pass Calculation.
•Difference between Late Finish and Early Finish is termed as
 Total Float 
•Activities with Zero total Float are called as Critical Activities
