Dear Readers,
The project's success relies on various activities, with effective scheduling being crucial. A project schedule refers to a tool used to communicate the timeline of a project, including its tasks, dependencies, assigned resources, and milestones. It serves as a roadmap for the project.
Key components of a project schedule are Project Milestones, Timeline, Tasks, Dependencies, and resources. Schedules are typically developed from the top down, like a pyramid. Starts from Level-1 (L1), Level-2 (L2), and will go up to Level-5 (L5).
L-1 Schedule = (Level 1) Management/Milestone Level Schedule
L-2 Schedule = (Level 2) Master Schedule
L-3 Schedule = (Level 3) Project Level Schedule
L-4 Schedule = (Level 4) Control Level Schedule
L-5 Schedule = (Level 5) Detail Level Schedule or Look-ahead Schedule
L1 may be a short table of milestones corresponding to "Top Management Summary."
L2 is a Master Schedule. It provides an integral plan of the Project activities for Project management. It is a "Project Management Summary."
L3 is a Project Level Schedule. It is a summary of activities from the level 4 schedule
L4 is a Control Level Schedule. It covers the whole project and doesn't go into the task-level detail, but should provide enough of a breakdown for clients to see what is happening at every step.
L5 is a Detail Level Schedule. It shows the lowest level of detail necessary to complete the Task. These schedules are temporary documents based on the 'Look-ahead' schedule and used to coordinate work in an area.
The schedules above help communicate the project plan and timeline to all stakeholders. They guide the project team through the sequence of activities and deadlines during execution, while also serving as a baseline to track progress, spot delays, and make adjustments as needed.
Common formats used to prepare and monitor the project schedules are Gantt chart, WBS & CPM
Gantt chart: A popular visual representation that uses a horizontal bar chart to show the timeline of tasks and their dependencies.
Work Breakdown Structure (WBS): It is a hierarchical chart that breaks down a project into smaller, more manageable tasks, helping to map dependencies.
Critical Path Method (CPM): A technique to identify the longest sequence of tasks that determines the minimum project duration. Any delay to a task on the critical path delays the entire project.
