Chapter 6, Problem 6DQ

Explanation of Solution

Gantt Charts:

A Gantt chart also known as bar chart. It is used for displaying the schedule information by specifying the activities of the project and the dates like when they start and finish in a specific calendar format.

• Gantt chart for the software projects usually contains milestones, tasks, task durations and arrows showing task dependencies.
• In software project Gantt chart, we generally have a black diamond symbol, thick black bars, grey horizontal bars, arrows and white diamond symbols.
• The black diamond symbol generally represents a milestone.
• The thick black bars with arrows represent the summary tasks.
• The grey horizontal bars represent the duration of each task.
• Arrows show the relationship between the tasks.
• The white diamond represents a missed milestone.

Critical Path Method:

Critical Path Method is a network diagramming technique. It is used for predicting the duration of the total project.

• This tool helps in combating the schedule overruns.
• It is also known as critical path analysis.
• Critical path is nothing but a series of activities, which determines the earliest time that a project needs to be completed.
• It has a less amount of slack and float.
• Slack and float is the time in which an activity can be delayed without actually delaying the project finish project.
• In order to develop a critical path for a project, we need to develop a network diagram first.
• Once the network diagram is created we can determine the critical path by estimating the duration of each activity.
• We use critical path to make schedule Trade-offs and to shorten a project schedule...
