Dependency lag: what to know

Note: if you want to jump right into editing your BuildBook Schedule, head over to our articles about creating your first Phase and using the Gantt Chart View.

BuildBook’s Schedule feature allows you to view and manage your project’s schedule using both a traditional calendar view or a Gantt chart view. You can feel free to switch between views, depending on which you prefer.

What’s a Gantt Chart?

The default project view in BuildBook is the Gantt chart. If this is your first time using a Gantt chart, all you need to know is that it’s a great way to visualize when your project’s events (aka Phases, Tasks, Change Orders, Selections, and Payments) start and finish, if they overlap, and helps define when one task should begin related to another - all on a single horizontal timeline. It also allows you to easily drag and drop events to change their duration and due date.

The right side of the chart shows a bar for each item, with a start and end date. Single-day events are diamond-shaped.

What are dependencies?

Dependencies are created by linking items together aka the parent/child relationship. They allow you to order items in a sequence, where one item must be completed (the parent) before the next item can begin (the child). If the date of one item changes, the dates of all other dependent items - or children - shift automatically as well. Learn more about how dependencies work in BuildBook here!

Dependency lag: what to know

So what happens to the time between items when things are moved around? The space between dependent items is also known as the lag.

  • When an item has dependents - such as a parent Task that has a few other Tasks linked to it - and you move the dates of the parent Task forward or backward, all of the dependent Tasks shift the same amount and the lag (time) between them is maintained.

  • If you need to adjust the dates for a child, like one of the dependent Tasks, then it won’t have an effect on the parent Task. It simply adjusts the lag between that child and the parent.

  • Dependent items in the schedule can overlap, where the dates of a child can start before the parent - also known as negative lag.

Pro tip: You can link Phases together in BuildBook - which is useful if there are project delays or changes to the timeline and you want many items in the Schedule to also adjust accordingly.
