INTRODUCTION
A workshop k h in i a software ft intensive i t i to t adopt d t
CMMI-DEV
Workshop Objectives
understand the organization business goals,
analyze the current state of the processes,
produce an estimation about the degree of
satisfaction of the current process regards the CMMI-
DEV V maturity a y level eve 3, aand
produce a general plan for a process improvement
cycle to achieve the defined business goals using the
CMMI-DEV maturity level 33.
Additional representation of the estimation in
terms of the recent ISO/IEC 15504-7
Organizational maturity levels

ASSESSMENT PLANNING
AAssessment t target: t t typical t i l successful f l l low maturity t it
organization – needs improvements
PRO2PI (“Process ( Capability p y Profile to Process
Improvement”)
a methodology for process improvement driven by a Process
Capability Profile model
defines exploratory assessment as an assessment with
the objective to explore options to support process
improvement in a small, low maturity enterprise
PRO2PI-WORK is a method for a workshop to
establish a PRO2PI
S CMMI DEV M i L l &
Scope: CMMI-DEV Maturity Levels 2&3
The assessment follows
ARC C requirements
ARC C requirements
ISO/IEC 15504-7 Class 3 requirements

ASSESSMENT RESULTS
The result of the preliminary assessment,
represented as CMMI-DEV Maturity Levels
Th The estimation ti ti is i that th t th the organizational i ti l unit it
will satisfy about 30% of ML 2 and about 35% of
ML 3

ASSESSMENT RESULTS
RResults lt may b be misleading i l di
CMMI-DEV maturity levels consider the engineering
process areas, even with low capabilities, only from
maturity i level l l 3. 3
This organization, however, has low capability good
development engineering practices.
An adjustment in the planning
to include a representation of these results using an
application pp of the ISO/IEC 15504-7 Organizational
g
maturity levels 1, 2 and 3 on the continuous representation
of CMMI-DEV model
The objective j of this decision was to produce p a better
result.
Process improvement point-of-view

ASSESSMENT RESULTS

Organizational Maturity Levels
Th The estimation ti ti is i that th t th the organizational i ti l unit it
will satisfy about 80% of OML 1, about 50% of
OML 2 and about 35% of OML 3

CONCLUSION
Based on this experience
Exploratory assessment results using the ISO/IEC
15504 15504-7 7 Organizational maturity levels 1, 1 2 and 3
was better than the same results using the original
CMMI-DEV maturity levels 2 and 3, in terms of the
communication i i about b the h current situation i i and d of f the h
orientation for a improvement cycle.
The evolution of the capability of engineering process
areas, from level 1 to level 2 and then to level 3, is
more explicitly in the ISO/IEC 15504-7
OOrganizational i ti l maturity t it levels. l l
This explicitly will help low maturity organizations to
understand better the path p to maturity y
level 3.
