Answer to Question 1

It is only on the complex schedules that this issue is a particular concern.
For example, if a schedule consists of 100 activities, it may be difficult to add an
activity to a bar chart and still accurately anticipate the impact of the change on the
entire schedule. With the use of a precedence diagram, the insertion of an activity is a
relatively simple matter. Each activity must generally have at least one predecessor
and at least one successor. With the precedence diagram, the logic is more readily
apparent and incorporating a new activity is a simple matter.

Answer to Question 2

One serious resource constraint (labor constraint) that is hampering many
construction projects today is the shortage of skilled workers. Various types of
material constraints might also exist. For example, the total amount of ready-mix
concrete that might be available for a project on a given day might be seriously
impacted by the capacity of the ready-mix supplier. An equipment constraint may
also exist, e.g., the firm might want to complete the project with the use of a single
crane. A safety constraint might consist of unseasonably hot or cold weather.
