Capability Maturity Model (CMM)

READ.ME   Instructions on downloading CMM material

The CMM notebook consists of two technical reports:

  SEI-93-TR-24  M.C. Paulk, B. Curtis, M.B. Chrissis, and C.V. Weber,
  "Capability Maturity Model for Software, Version 1.1" Software 
  Engineering Institute, CMU/SEI-93-TR-24, February 1993.

  SEI-93-TR-25  M.C. Paulk, C.V. Weber, S. Garcia, M.B. Chrissis,
  and M. Bush, "Key Practices of the Capability Maturity Model, 
  Version 1.1" Software Engineering Institute, CMU/SEI-93-TR-25, 
  February 1993.

The various ways of obtaining these technical reports are described in
the file 
This file, READ.ME, provides instructions for downloading ASCII,
Postscript, RTF, or MacWord versions of the technical reports, as well
as various other items that may be of interest.

The files are contained in various subdirectories:  

In the initial net version some files had an index specifically for that
section (e.g., had a Level 2 index at its end), which were used
in  building the master index in the TR-25 Appendices.  They were
originally left in for the use of people who might only want, for
example, the Level 2 key practices.  They were not, however, actually a
part of TR-25 as  distributed in hardcopy.  These led to so much
confusion for some people that the files were updated with those indices
removed, so there have been two versions of CMM v1.1 available by
Internet.  The current version corresponds to the hardcopy as
distributed by the SEI.

= = = ASCII versions contained in subdirectory "ASCII"

The ASCII text of "Capability Maturity Model for Software,"
SEI-93-TR-24,  consists of one file:

The ASCII text of "Key Practices for the Capability Maturity Model  for
Software," SEI-93-TR-25, consists of the following files and should be
printed in this order:
  tr25-overview.ascii   overview of key practices and how to read them
  tr25-ml2.ascii        KP's for ml2
  tr25-ml3.ascii        KP's for ml3
  tr25-ml4.ascii        KP's for ml4
  tr25-ml5.ascii        KP's for ml5
  tr25-appendices.ascii the appendices to TR-25 (references, glossary,
                        abridged practices, change history, index, 
                        change request form)

You are warned that the ASCII text version of the report is very
difficult to read because of the loss of formatting in going from Mac
Word 5.0a to ASCII. These files were updated on 12 March 1993 due to the
update to the RTF files giving us a version without embedded index
entries, which may make them easier to use.

= = = Mac Word 5.0a versions contained in the subdirectory "MacWord"

The primary electronic version is a set of Mac Word 5.0a files, which 
have been compressed and formatted for net distribution using StuffIt 
and BinHex.  The archives are:

Since the last shareware version of StuffIt was 1.5.1, for wider
compatibility the StuffIt archives are in that version.

The Mac Word files use Palatino and NewCenturySchoolbook font, and you
should use Word 5.0a to get the right spacing.

= = = Postscript versions contained in the subdirectory "Postscript"

The Postscript versions are in files        title page for TR-24

and      title page for TR-25 contains the copyright page and release letter for the reports.

WARNING:  The first line in the Postscript file may have to be edited to
(Adobe version number removed) to work correctly when moving from Mac to
Unix systems.  If you have problems printing any .ps files, check this. 
Please don't contact me with Postscript problems; I'm not a Postscript
expert. Also the Postscript files tend to be very large because of the
fonts that are downloaded with them.  There is a file called
that has some of the e-mail I have received that may be of some use to
the Postscript users.  I have updated the Postscript files as of 7 May
1993 to correct (I hope) some of the problems, including the very large
size of the files (by not including the font definitions).  They should
work better now...

>> Binary versions of MS-Word files contained in the subdirectory "Binary"

For those who can't handle StuffIt and Binhex, there is a binary version
of the files in this subdirectory.  Remember to set binary mode when

= = = RTF versions contained in the subdirectory "RTF"

For the PC users in the world, there is an RTF version of the files (as
created from Word 5.0a) in subdirectory RTF.


These files were updated on 12 March 1993.  The RTF version lost all
index entries, which meant that the "important terms" were missing from
that version of the TRs.  When this was reported, we removed the index
entries and generated a version of CMM v1.1 that has no hidden text. 
This may have implications for table of contents, pagination, and the
index, but should make the RTF version usable.  We updated the ASCII
version, which included the hidden text, as another effect of this

= = = Letters to the Correspondence Group in subdirectory "CG_letters"

These are in ASCII and named by date.

= = = Working material for ISO JTC1/SC7/WG10 will be stored in "wg10"

This is for working group use only, please.

= = = Miscellaneous items contained in subdirectory "Misc"

We will update this to v1.1 later, and there will be a new map when the
new  questionnaire comes out.

There is a Postscript version of a paper entitled "Software Process 
Assessments:  Issues and Lessons Learned" presented at ISQE92 in

There is a Postscript version of a paper entitled "U.S. Quality Advances:
The SEI's Capability Maturity Model" to be presented at the Third European
Conference on Software Quality in

  The Software Engineering Institute has developed a five-level 
  Capability Maturity Model for Software that describes how software 
  organizations mature as they improve their software process.  This 
  model has evolved since its initial publication in 1987 to a 
  reasonably detailed description of software engineering and management
  processes.  This paper describes the evolution of the model in terms 
  of its focuses at each maturity level and discusses some of the issues
  that may influence its future evolution.
