CHAPTER 6: CMMI REPRESENTATION
CMMI representation
staged representation
organizations follows proven sequence of improvement path in maturity level
each level serves as foundation for next level
continuous representation
organizations may select order of improvement that best meet organization's business activity
comparison across maturity level
comparison between maturity level & capability level
capability level
known as CONTINUOUS representation
enable organizations to incrementally improved process corresponding to individual process area selected by organization
achievement (current status, determined by appraisal)
target profile ( organization goals for improvement, used for action planning)
a process is performed or incomplete is important
name "incomplete" given to continuous representation starting point
numbered 0 through 3
maturity level
known as STAGED representation
enables organization to improve a set of related process by incrementally addressing successive set of process area
inherent in maturity level
move from current maturity level to next
individual processes are performed or incomplete is not primary focus
name "initial " given to staged representation starting point
numbered 1 through 5
capability / maturity
0 - incomplete / -
1 - performed / initial
2- managed / managed
3 - defined / defined
4 - - / quantitatively managed
5 - - / optimizing
SIMILARITY
: name of level 2 (
managed
) and level 3 (
defined
) are the
same
in both
DIFFERENCES
: continuous - no capability level 4 and 5 (name used for capability level 1 is
performed
)
staged - no maturity level 0 (name used for capability level 1
initial
)
continuous representation
categories of process area
process management
defining
planning
resourcing
deploying
implementing
monitoring
controlling
appraising
measuring
improving
project management
planning
monitoring
controlling project
engineering
cover development and maintenance activities that shared across engineering discipline
support
cover activities that support product development and maintenance
staged continuous
provides proven sequence improvement
provides a single rating summarize appraisal results and permits
provides easy migration from SW-CMM to CMMI
MATURITY LEVEL
(evolutionary plateau of process improvement)
5(focus on continuous process improvement) / optimizing
4(process measured and controlled) / quantitatively managed
3(process characterized for organization and is proactive) / defined
2(process characterized for project and often reactive) / managed
1(process unpredictable, poorly controlled and reactive) / initial
CMMI provides 2 ways to view improvement level
CAPABILITY
achievement of process improvement within an individual process area
described by specific practices goals for process area
MATURITY
degree of process performances across a predefined set of process area
goals are attained for each process area
comparing representations
continuous / staged
maximum flexibility for order process improvement / predefined and proven with case study and ROI data
focus on improvement within process area / focus on organizational improvement
improvement of process area can occur at different rates / overall results summarized in maturity level
source selection investigation can target risky at any area / maturity level are common discriminators
ADVANTAGES between continuous and staged
continuous / staged
easy migration from SECM to CMMI / easy migration from CMM to CMMI
allows improvement of different process to performed at different rates / summarize process improvement result in a simple form a single maturity level
enables increased visibility of capability achieved in each individual process area / focused on a set process provide an organization with a specific capability that characterized by each maturity level
