Using Precedence Tables to Plan Tasks

Introduction to Precedence Tables

Understand that a precedence table is a visual representation that aids in scheduling and sequencing tasks.
Know that precedence tables show the order in which tasks must be performed, the duration of each task and their dependencies on other tasks.

Recognise that precedence tables are frequently used in project management to help plan and coordinate tasks effectively.
Understand that by using a precedence table, project planners can ensure that activities are scheduled to be completed in the most efficient order, taking into account dependencies between tasks.

Gain knowledge that to construct a precedence table, one needs to list all the tasks required to complete the project, the estimated completion time for each task and which tasks depend on others.
Notice that tasks are usually represented as rows in the table, while the dependencies between tasks are represented in a separate column.

Appreciate that a precedence table can be used to identify the critical path in a project, which is the sequence of tasks that takes the longest time to complete and thus determines the minimum duration of the project.
Comprehend that identifying the critical path can help project managers allocate resources more effectively and possibly cut down project time by overlapping non-dependent tasks.

Understand that precedence tables may need adjustment as circumstances change, such as tasks taking longer, relationships between tasks changing or new tasks being added.
Realise that it’s important to keep the table up-to-date in order for it to be a helpful tool in managing the project.
Be aware that any changes to tasks or dependencies may have knock-on effects on other tasks, highlighting the importance of careful planning and regular reassessment.

Realise that precedence tables can greatly aid in the efficient planning and progression of a project, as well as helping to visualise the process and dependencies.
Understand that while they are a useful planning tool, precedence tables do not guarantee a project will finish on time or without issues. unknown or unpredictable factors can still influence a project’s progress.
Recognise that they are a tool, and their effectiveness is dependent on accurate information, thorough analysis and diligent management.
