Question

A bar (gantt) chart A) represents project work items or activities as a time scaled bar B) is the same as network schedule C) is not effective as a graphic representation of a schedule D) effectively illustrates the logic of activity sequences

Answer 1

A bar (Gantt) chart represents project activities as time-scaled bars, distinct from a network schedule and is effective in illustrating project schedules.

Step-by-step explanation:

A bar (Gantt) chart is widely used in project management and represents project work items or activities as a time-scaled bar. Each bar on the chart indicates the start and end dates of each activity, making it easy to see the schedule at a glance. This type of chart is indeed effective in illustrating project schedules and is different from a network schedule, which shows interdependencies between tasks. Unlike Gantt charts, network schedules (or PERT/CPM diagrams) highlight task sequences and their logical relationships more explicitly.

To compare, a line graph is effective for showing trends over time, such as the unemployment rate, and a bar graph uses the height of bars to show relationships and can represent entities or subgroups with its segments. These visual representations of data aid in understanding trends, patterns, and comparisons, simplifying complex data into interpretable visuals.
