How do I set a cross-project dependency

Birdview supports cross-project dependencies. It means you can set a dependency between activities not only within the same project, but between different projects as well.

Two activities are called ‘dependent’ if one’s timing is dependent on that of the other, such as when one finishes the other one starts, or when one is to start exactly in a week after the other is complete.

In activity dependency, the following definitions are used:

• Master activity - the one whose start or end date is used as a reference for another activity.
• Dependent activity - the activity that starts/ends according to a rule, called dependency, linking it with a master activity's start or end date.

To set a dependency between two activities belonging to two different projects, follow this procedure:

1. Log in as user with ‘Add new activities’ permission (e.g. Project Manager). If you are already logged in, skip this step.
2. Open Activity center.
3. Locate the activity whose dependency you want to change.
4. Click the dependency attribute button ().
5. Select the project the master activity belongs to. The project names are given in bold font. As you click the project name, a list of activities under will open.
6. Select the master activity from the list.
7. Select among three types of dependency available: Start to finish, Finish to start, and Start to start. Selecting any of the three options other than No dependency opens additional fields.

8. Use the slider, or type in the required lag in days. This will set the dependent activity to start/finish # days after/before the first one finishes, depending on whether the delay is a positive or negative integer (e.g. -3).
9. Click Save.

Use cases

Below are examples of how each type of dependency would be used, in a real world example. We've chosen making and selling home-made jam from freshly picked berries to illustrate each type:

1. Finish to Start (F-to-S): You need to "Finish the task of picking the berries" before you can "Start the task of crushing and mixing the berry mixture" for cooking.
2. Start to Start (S-to-S): You need to cook the berries, and then put them into sterilized jam jars. You can "Start the task of cooking the berries" and "Start the task of sterilizing the jars" at the same time.
3. Start to Finish (S-to-F):Your Jam is very popular and you have many orders from interested shop owners. This kind of dependency is best used when you know when your customers need to have the jam delivered and in their stores (for Christmas or Thanksgiving, for example).  So, you know the end date of the last task, and your predecessor tasks will have their start dates created by working backwards from there. Further, durations become more important than actual start dates or end dates for preceding tasks, in this type of dependency.

Multiple dependencies

You can have two or more cross-project dependencies (up to 10) created for an activity. Only activities that can be linked with it by dependency will appear on the Depends on drop down list. Birdview will analyze which type of dependency can be set with a particular activity of another project.

1. To create another cross-project dependency for the activity, click 'Add more dependencies'. A new tab will appear.
2. Follow steps 3 to 5 above to create new cross-project dependency.
3. If more dependencies are needed, use the green '+' button.

Deleting dependencies

To delete a dependency:

1. Enter the dependency editor as described above for the activity you want to edit.
2. For multiple dependencies: Select the dependency you want to delete by clicking the respective tab.
3. Click Remove dependency.
