Answer to Question 1
Traditional bar charts do not show the interrelationships between activities,
as they show only the timescale of when each activity is to occur. This makes it
difficult to add activities that were left out in the original schedule. As a result,
complex projects do not lend themselves to scheduling. Even if a project is scheduled
successfully with a bar chart, updating the schedule can be very cumbersome. The
impact of changes is difficult to show with bar charts.
Note: The above answer is given purely as a response to the traditional use of bar
charts. With the use of computers, a project can be scheduled as a precedence
network and with a keystroke the bar chart of the project is displayed. In addition, the
bar chart can generally be displayed with the dependencies between activities also
shown. Thus, the disadvantages noted above do not apply to most conventional
computer scheduling software packages.
