Quality management comprises:
Acceptance coordination
Operational readiness check
Trial operation.
Normally the functional segments depicted sequentially in Fig.
2.1
are carried
out overlapping or phase shifted. The sequence in the diagram only underlines their
logical interdependence. Different tasks are naturally taken care of in different
approaches corresponding to the acceptance object. A single change request to be
implemented will require less attention than a complete release from the planning
phase to operational readiness.
2.3 Sub-project Structures
Depending on the importance of the tasks outlined above responsibilities in an
implementation project are distributed in such a way that they form a sub-project
structure (Fig.
2.2
).
In this figure the tasks
Request management
Change management
Error management
are grouped together with overall release planning. This need not always be the
case. Error management could for example be a sub-project in its own right.
Quality management comprises the responsibilities outlined in Fig.
2.1
.A
separation of one of them into a different sub-project would not make sense.
Some problem areas related to data management or data quality etc. are grouped
together under a single sub-project responsibility.
Operations, service centre and documentation have not been separated as indi-
vidual sub-projects. They can be assigned to one of the three fields of competence—
for example documentation as part of quality management—or temporarily inte-
grated from line functions into a project (service centre and operations). Interface
operations are mentioned explicitly here. The reason for this is that there is quite
often the requirement to run certain interfaces independently from end user inter-
vention via separate job control scripts by a service centre.
The processes and responsibilities depicted in Figs.
2.1
and
2.2
present only an
extract from the overall process world. Development, project planning and control-
ling and other functions have been left out on purpose, since only functions in
