Task dependencies and constraints
There are two major aspects that affect sequencing decisions in a schedule. These are as follows:
- The inherent relationship of dependencies between the project tasks
- The inherited set of constraints on the project
We will now investigate how these dependencies and constraints can be realistically reflected in our schedule using Project features.
Task relationships
As the famous saying goes, no man is an island, and similarly, within a schedule, no task should exist in isolation. Consider the following diagram, which denotes a relationship between two tasks:

Tasks in a project derive their meaning only in relation to other tasks. For example, if you are building a house, it is mandatory to build the foundation before your build the walls, and only after you build the walls can the roof be constructed. The universal law of gravity mandates these particular...
