You can refine large or complex initiatives by creating lower-level, contributing child initiatives. This enables you to break down complex initiatives into a series of steps. Sub initiatives share the characteristics of the parent initiative, but their status does not roll up to the parent initiative.
To add sub initiatives to initiatives:
From the Browser View or any report, select the object to which the parent initiative is attached.
Right-click the initiative and select Add.
The Initiative Setup page is displayed.
The high-level parent initiative is identified as a dependency.
Define the subinitiative. See .Creating Initiatives
