List of KPAs for each level
CMMi - Introduction
• CMMi – Capability Maturity Model Integrated
• A set of best practices, organized under different
key process areas
• Software Engineering Institute (SEI) of Carnegie
Mellon University (CMU) and US Department of
Defense (DoD) did an elaborate study in many
top software and hardware companies
• They compiled the best processes that yielded
good results in all these companies
• That has become a rule book for others to follow
• This can be used as a scale to measure the
process capabilities of a company
CMMi - Introduction
• CMM was initially introduced
• CMM had gaps in areas of electronic/hardware
processes, systems engineering, supplier
processes, team processes with respect to
software processes
• Hence CMM was improved to bridge these gaps
and the new process was called CMMi
• CMMi has got 2 variations – staged and
continuous
Basic Terms
•
KPA – key process area
– A set of related activities, events and deliverables. A group or department may
take the main responsibility
•
CG – common goal
– A generic aim to be achieved
•
GP – generic practice
– A generic set of activities to be followed
•
SG – specific goal
– A specific aim to be achieved within the KPA
•
SP – specific practice
– A specific set of activities within the KPA to be followed
•
AB – ability
– What enables to carry out the activity
•
VE – verification
– How to ensure the KPA is followed well
•
DI – directing implementation
– Reviewing status with management, maintaining documents
•
CO – commitment
– What are the commitments the management need to provide to implement the
KPA

Levels
• L1 – Initial level. Totally adhoc processes. Success
depends on individual capabilities of people
• L2 – Managed. Project level processes are established.
Requirements are managed. Successful process in a
project can be a role model to others. Each project level
process may be different
• L3 – Defined. Organizational level processes are
established. These are tailored to projects. Consistency
is established across the board. All engineering activities
are covered.
• L4 – Quantitatively Managed. Every aspect is measured
and statistically compared. Predictability of success is
high.
• L5 – Optimizing. Continuously measure and improve all
processes and variations. Optimize at organization level.
Common Features
•
Establishing an organizational policy
– At the apex level we need to define a policy to implement the KPA
– This is a commitment
•
Institutionalize the process
– The process must be consistently implemented across the organization
– This will increase predictability
•
Plan the process
– Every process implementation must be planned and tracked
•
Provide Resources
– Provide human resources, hardware and software resources, necessary tools
•
Assign Responsibility
– Different stakeholders in the KPA must take specific work areas
•
Train People
– Educate people on the respective KPAs
•
Manage Configurations
– All documents and work products must be tracked for versions and approval
levels
Common Features
• Monitor and control process
– Ensure the tracking is done at all levels
• Objectively evaluate adherence
– Measure adherence and associate numbers
with it across the organization
• Review status with management
– Status must be communicated and reviewed
periodically
Stakeholders

Senior management
Project Management
Project members (engineering teams)
Support groups
Quality group
Supplier Management group
Customer interaction group
Assessment Process
• A team of appraisers will be formed along with authorized lead
appraiser (ALA)
• The team will undergo training conducted by ALA
• A sample set of projects will be taken with all related work products
• All documents will be reviewed – every compliant area will be
marked and sticky notes will be attached to the documents
• A wall chart is prepared with KPA compliance areas with respect to
quality management documents and project documents
• A team of members will be randomly selected from all groups of the
organization
• The appraising team will interview all selected members with a lot of
relevant questions to ensure the process knowledge and adherence
• Every checklist item will be ensured for adherence
• Depending upon the KPAs satisfied by all team members, the
assessment level will be awarded
