Process Maturity
Process reliability is defined as the
failure-free execution of an
operational process or activity and
is determined by measuring two
things: consistency and stability.
Process adaptability is a qualitative
multivariate attribute derived by
equating and comparing process
flexibility, re-usability and
standardisation. Process
adaptability is an early indicator of
how readily a process can be reused
to deliver other business
outputs (services).
Enough information needs to be
captured under this measurement
category to indicate how mature a
process is. Often, maturity is
inferred from a number of
measurement indicators that cross
multiple measurement categories.
For example, a mature enterprise
architecture practice is a
productive, efficient practice, which
has high degrees of
standardisation, resulting in low
task complexity.
A measurement indicator for
maturity will be specific to the
methodology being used to
benchmark and measure the
process. This information should be
recorded within any measurement
indicator.
A. Consistency
Qualitative measures that describe how successful
a process is in producing consistent outputs under
any execution load.
B. Stability
Quantitative measures of the rate of error and/or
the rate of failure of agencies’ processes. The
sources of error and failure for a business process
or activity will depend on the nature of the process,
whether it is automated or manual, whether it is
geographically dispersed or localised, whether it
supports a service or delivers a product, and so on.
A. Flexibility
Qualitative measures that describe how rigid an
operational process is; most commonly
represented as an index.
B. Re-usability
Qualitative measures of how readily a business
process can be re-used to deliver alternative
outputs.
C. Standardisation
Qualitative records of the standards supported and
implemented by a process.
A. Standard
Qualitative measures that describe the formalised
level of maturity the process being measured has,
based on recognised industry standards, such as
ITIL, P3M3 and so on. Not all business processes
and activities will have a maturity level indicator, as
there are many business processes and activities
present within an organisation where no formal,
recognised maturity scale exists. Agencies may
choose to use this indicator for internal
performance improvement purposes, provided a
method of measurement and a maturity scale are
defined within the measurement indicator(s).
