External calls consist of the URL to an external application, combined with a set of optional parameters defined by the site administrator. External Calls can serve multiple purposes. One use case might integrate SLIM-Collaborate with an existing enterprise workflow. For example, when the current solution for an estimation project is officially approved, a user can launch an external call to automatically push detailed cost, effort, or staffing estimates by role to an external PPM tool. External calls could also be used to augment existing SLIM-Collaborate features. One example might be used once an estimation solution has been reviewed by the project owner. A user can edit the project and call the QSM Agile Adjuster to align phase durations and overlaps with the project’s sprint count and cadence. Once these adjustments have been made, the solution workflow status could be changed from ‘Reviewed’ to ‘Approved’.
