Deleting, or in Portfolio Manager terms ‘Retiring’, is an important action, which can have serious implications which need to be understood by other projects.
To start with you can branch from an ‘Implemented’ baseline element, but signal that you’re thinking about retiring it. Portfolio Manager gives such elements a ‘branchedToRetire’ status. Now, if other projects also branch from the original baseline element, they will be alerted to the idea that you are thinking about retiring this element.
You can also move a ‘branchedToRetire’ element into a ‘plannedToRetire’ state, which tells everyone that you have a firm plan to retire this element.
You will need to use the Impact Analysis tool each time you create a ‘branchToRetire’ or ‘plannedToRetire’ element.
