CMM IS A STD FOR COMPANY PROCESS.FULL FORM capability 
maturity model.5 cmm levels.ISO iS ALSO THE SAME THING.I 
ndian standard organization.

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.
