Here’s a complete, easy‑to‑follow guide on how to set predecessors in Microsoft Project:
- Let's begin by opening your project in Microsoft Project and making sure you're in Gantt Chart View.
- In the task table on the left side of your screen, right-click on any column header to open the context menu.
- From the context menu that appears, select 'Insert Column' to add a new column to your task table.
- In the field that appears, start typing 'Predecessors' to filter the available columns.
- When you see 'Predecessors' in the dropdown list, click on it or highlight it and press ENTER to add it to your table.
- The 'Predecessors' column now appears in your task table, ready for you to establish task dependencies.
- Click in a cell within the 'Predecessors' column next to the task you want to set a dependency for.
- Type the ID number of the predecessor task, or click the dropdown arrow to select from a list of available tasks in your project.
- That's it! setting predecessors creates task dependencies so Microsoft Project can automatically schedule dates.
