Task Relationships available in MSP

Task Relationship in Microsoft Project 2010 is of 4 types

1. Finish-to-Start: - The successor task cannot be started until its predecessor task completed. For example if you have two tasks “requirement captured” and “Designing” then “Designing task” cannot be started until “requirement captured” task is completed.

2. Start-to-Start: - Two tasks, let say A and B has start-to-start relationship and task B is Dependent on Task A, then the task B cannot start until task A starts. It means that dependent task start only when or after the task on which it is dependent is started. For example if you have two tasks in Microsoft project 2010 “Pour concrete” and “Level concrete” then "Level concrete" cannot be begin until "Pour concrete” task begins.

3. Finish-to-Finish: - In this type of relationship, let say A and B has Finish-to-Finish relationship and task B is Dependent on Task A, then the task B cannot completed until task A completed. It means that dependent task completed only when or after the task on which it is dependent is completed. For example if you have two tasks in MSP “Coding” and “Testing” then “Testing” task cannot be completed until “Coding” task is completed.

4. Start-to-Finish: - - In this type of relationship, let say A and B has Start-to-Finish relationship and task B is Dependent on Task A, then the task B cannot be completed until task A starts. It means that dependent task completed only after the beginning of the task on which it is dependent is started. For example if you have two tasks "Truss delivery" and "Assemble roof". The "Assemble roof" cannot be finished until the "Truss delivery" task started.
