A '''process-data diagram (PDD)''', also known as '''process-deliverable diagram''' is a [[diagram]] that describes [[process (computing)|process]]es and [[data]] that act as output of these processes. On the left side the [[meta-process model]] can be viewed and on the right side the [[metadata modeling|meta-data model]] can be viewed.<ref name="WSVB">I. Van de Weerd, J. Souer, J. Versendaal and [[Sjaak Brinkkemper]] (2005). ''Situational Requirements Engineering of Web Content Management Implementations''. SREP2005.</ref>

A process-data diagram can be seen as combination of a [[business process model]] and [[data model]]. It is not important any more but it is useful right simeplfuly.

The process-data diagram that is depicted at the right, gives an overview of all of these activities/processes and deliverables. The four gray boxes depict the four main [[implementation]] phases, which each contain several processes that are in this case all sequential. The boxes at the right show all the deliverables/[[concept]]s that result from the processes. Boxes without a shadow have no further sub-concepts. Boxes with a black shadow depict complex closed concepts, so concepts that have sub-concepts, which however will not be described in any more detail. Boxes with a white shadow (a box behind it) depict open closed concepts, where the sub-concepts are expanded in greater detail. The lines with diamonds show a has-a relationship between concepts.

The [[SAP Implementation]] process is made up out of four main phases, i.e. the project preparation where a vision of the future-state of the SAP solution is being created, a sizing and blueprinting phase where a [[solution stack|software stack]] is acquired and [[training]] is being performuuedperformed, a functional development phase and finally a final preparation phase, when the last [[Software testing|tests]] are being performed before the actual go live. For each phase, the vital activities are addressed and the [[deliverable]]s/[[Product (business)|product]]s are explained.
