The management practices are applicable to all processes. They are
designed around the achievement of the principal management functions
of planning, organizing, resourcing, and controlling. Attribute indicator sets
are associated with each management practice and represent the types of
evidence that substantiate judgments of the extent to which the management
practice is performed [8]. The attribute indicator sets are listed here:
• Practice performance characteristics that provide guidance on the
implementation of the practice;
• Resource and infrastructure characteristics that provide mechanisms
for assisting in the management of the process;
• Associated processes from the process dimension that support the
management practice.
An example of management practices for capability level 2 is given in
Table 3.7.
The capability level achieved by a process is derived from the applicable
attribute ratings for that process. For example, level 2 is determined by these
rules:
Level 2
Process performance [the performed
process (CL 1) is now managed]
Process attribute 2.1, Performance
management
Process attribute 2.2, Work product
management
