The sum of activity durations of the longest path in a network indicates expected project completion time, and the activities on it are called the critical activities. True False<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

Correct Answer: True<\/strong><\/h3>\n\n\n\n

The sum of activity durations of the longest path in a network represents the expected project completion time, and the activities on this path are called critical activities. This is based on the concept of the Critical Path Method (CPM)<\/strong>, which is widely used in project management to schedule project tasks efficiently.<\/p>\n\n\n\n

Explanation:<\/strong><\/h3>\n\n\n\n

In a Project Network Diagram<\/strong>, different paths connect the project\u2019s start and finish. Each path consists of multiple activities, each with its own duration. The longest<\/strong> of these paths, in terms of total duration, is known as the critical path<\/strong>. The activities on this path are referred to as critical activities<\/strong> because any delay in these activities will directly extend the project’s completion time.<\/p>\n\n\n\n

Why is the Critical Path Important?<\/strong><\/h4>\n\n\n\n
    \n
  1. Determines Project Duration<\/strong> \u2013 The total duration of the critical path gives the minimum<\/strong> time required to complete the project.<\/li>\n\n\n\n
  2. Identifies Critical Activities<\/strong> \u2013 Activities on the critical path must be monitored carefully since they have zero slack<\/strong> (float), meaning any delay in these activities will cause a delay in the overall project.<\/li>\n\n\n\n
  3. Resource Allocation<\/strong> \u2013 Helps project managers allocate resources effectively, ensuring that critical tasks are prioritized.<\/li>\n\n\n\n
  4. Risk Management<\/strong> \u2013 By identifying critical activities, project managers can take preventive actions to reduce the risk of delays.<\/li>\n<\/ol>\n\n\n\n

    Example<\/strong><\/h3>\n\n\n\n

    Suppose a project has the following tasks:<\/p>\n\n\n\n

      \n
    • Task A (3 days), Task B (4 days), Task C (5 days), Task D (2 days)<\/li>\n\n\n\n
    • If the longest path is A \u2192 B \u2192 C<\/strong>, totaling 12 days<\/strong>, this will be the project’s expected completion time.<\/li>\n\n\n\n
    • Tasks A, B, and C are critical activities<\/strong> because delaying any of them will extend the project duration.<\/li>\n<\/ul>\n\n\n\n

      Thus, the statement is True<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
