Hi CMM -Capability Marturity Model this the old version now
all the IT industries are following CMMI-Capability
Marturity Model and Intergration. actuly this is also for
other industries other than IT industries. but every one
assumes CMMI is only for IT companies.
CMMI is Process but not a Model. It only tells us this is a
better way to get good result. but this CMMI does not
Implies any hard rule tht all the companies should follow
its methods/standards.
In CMMI there are 5 levels
CMMI Level 1 Initial : In this company would not have any
specific plan or procedure to carry out the
project/development of software.
CMMI Level 2 Managed : In this stage the company is
depended on one particular person eg: lets think u r
organisation has TL/Manager under his guidence the company
is running well in profits all rules, all plans are under
his control. if the person leaves the organisation with any
reason then wht is the state of company ? thtsy it is
called as Managed level CMMI does not want it organisations
under 1control.
CMMI Level 3 Defined : in this level all the set of rules
are mentioned . in detail, all plans are disussed among the
teams formations of various teams, etc when ther is aset of
aplan it should be discussed among all the teams then only
it is finilised and gets it into implemented. in level 2 we
dnt find any Individuality but in this Level 3 all should
accept it or else it cannot be implemented. thts wht CMMI
states all team members should accept proposal.
CMMI level 4 Quantatitive Managed : At maturity level 4,
the organization and projects establish quantitative
objectives for quality and process performance and use them
as criteria in managing processes. Quantitative objectives
are based on the needs of the customer, end users,
organization, and process implementers. Quality and process
performance is understood in statistical terms and is
managed throughout the life of the processes.
CMMI level 5 Optimising :focuses on continually improving
process performance through incremental and innovative
process and technological improvements. Quantitative
process improvement objectives for the organization are
established, continually revised to reflect changing
business objectives, and used as criteria in managing
process improvement. The effects of deployed process
improvements are measured and evaluated against the
quantitative process improvement objectives. Both the
defined processes and the organization’s set of standard
processes are targets of measurable improvement activities.
Generaly there is alot of work in level 3 only than other
levels.level2 and level1 no one counts . company can
directly go for level 3 assesment. without following 2 and
1 levels. but cnt go for 4 and 5 directly.
ISO : International Standards for Organisation
Generally ISO does not have any rules to be followed but it
only checks are you following as u have mentioned in
company.
In todays IT companies want sell there products/Projects in
the market or clients they look wether the company is havg
the CMMI standards or not it has became a neccessity for IT
companies.
Thank you Guys.
