Please provide reference to the question below

To develop a schedule for a project, we will use the concept of a project network, which shows work activities taken from the work breakdown structure and is organized according to the logical flow in time and relationships governing when the work will be performed. By combining this network of work activities with estimates of the time duration for performing each of the activities, we can create a schedule for the project work. What types of information can we learn about the project by reviewing the project schedule and all the information used to generate it?
