The essence of task dependency

Many things in life depend on some other things getting ready or done. While planning it is useful to define the relationship between such things, so as not to be distracted by what you are not yet ready to put into motion. We suggest you find out how the dependency function in MLO helps to solve this.

What is dependency in MyLifeOrganized?

As you know, the MLO task planner solves the issue of what should be worked on further, showing only currently important tasks in the To-Do list. If a task depends on the completion of another, it cannot yet be completed, and therefore should not be shown in the To-Do list.
Dependency is a special option that allows you to block the appearance of a task in the To-Do list until certain other tasks are completed. When all the dependencies are satisfied, then the task appears in the To-Do list.
Suppose you plan to buy a new bike, but realize that it’s actually impossible until you complete a project and get your bonus. You’d like to add this task to the list so that it, on the one hand, would not clutter up your To-Do list, and on the other hand, would not be completely lost.

You can set a dependency for a task in Properties: Dependencies -> click to add dependencies -> Select the task (use Ctrl for multi select) -> Ok.


Tip. To quickly set a dependency drag a primary task into a secondary one with the right mouse button. Then select “Add to the dependency” in the menu that appears. This will make the secondary task dependent on the primary.

It’s like you freeze the dependent tasks for a while. It will become active and appear in To-Do only after certain other tasks are completed.

The dependent task is indicated by the corresponding icon:


Dependency can be used for multiple tasks from any branches

Basically the dependency feature can be viewed as a more sophisticated version of another MLO feature - complete subtasks in order. But if in the case of subtasks in order they are activated strictly one after another inside the selected branch, with dependencies the order and number of tasks do not matter. Completing several tasks can "activate" several other tasks from any branch, not affecting due dates (or start dates) of the dependent tasks.

Here is an example when the completion of one task activates not only the next task on its branch, but has an impact on other projects.

For instance the project “Make repairs” is familiar to many. It includes among other such subprojects as electrics and walls with their subtasks:



We will not be able to plaster, paint the walls and glue wallpaper until we have electrics. We set the dependency for these tasks:


And we can install the sockets only after all the work on the “Walls” project has been completed. Set the dependency as well:


And we get a concise to-do list that is easy to manage:













Tip. If you still need to see the dependent tasks in the view “Active Actions”, set “Available” in the Action Filter.

Dependency can be satisfied when performing all or at least one of the selected tasks

If you want to unblock task A when only one of the tasks B, C or D is completed click on ALL/ANY link to set the appropriate option.


Delayed dependency

MLO also provides for a concept of a task not becoming active until after a certain time period. We call it delayed dependency.

For example, you can see the task "Hang wallpaper" activated in 1 day after you complete the dependent task "Paint the door".


Keep in mind that the "Delay" option affects when the next task will become "Active" but does not act on the dates.

Note. If all tasks need to be completed to open the dependency (option ALL set) then the delay will count from the time of the last task completed. If ANY option is set for the dependency then the delay will count from the time of the first task completed in the dependency list.
