This document provides an overview of the Capability Maturity Model Integration (CMMI). It discusses that CMMI is a process improvement model that provides best practices for planning, executing, and monitoring projects. It aims to improve an organization's performance and ensure delivery of high-quality products and services. The document outlines the five maturity levels in CMMI and lists the process areas it addresses. It also discusses the history and development of CMMI and compares it to agile methods. The document notes that while CMMI and agile may have some differences, organizations can take a hybrid approach and introduce agility into CMMI processes.

1. CMMI
Arnon Rotem-Gal-Oz

2. The king’s Ship Wasa - 1628
 No Specification
 No Architecture description
 Changes done on the fly,
often under
market/customer pressure
 Testing ignored
 Didn’t know how to tell the
clients No
 The system last longer than
was ever imagined
 Maintenance costs far
exceed ordinary
development

3. PEOPLE
PROCESS
TECHNOLOGY

4. Underlying Premise of Process
Improvement
“The quality of a product is
largely determined by the
quality of the process that is
used to develop and
maintain it.”
Based on TQM principles as taught by
Shewhart, Juran, Deming and Humphrey.

5. The Software Development
Paradox
High-Quality but Slow to Market
Not a Leader
Speed
Quality
Fast to Market but Low Quality
Low Customer
Satisfaction

8. Model
 Say what you do
 Do what you say
 Prove It

ones that will move you DOWN one full
level on your process scale”
(Peopleware) [3]

14. CMMI vs. Agile
PEOPLE
TECHNOLOGY
Process

15. The Agile Software Manifesto
•Individuals and interactions
over processes and tools
•Working software
over comprehensive documentation
•Customer collaboration
over contract negotiation
•Responding to change
over following a plan
[7]Agile

16. CMMI Practices vis-à-vis Agility
 “LEVEL 1”
 Identify scope of work
 Perform the work
 “LEVEL 2”
 Organizational policy for plan, perform
 Requirements, objectives and plans
 Adequate resources
 Train the people
 Assign responsibility and authority
 CM for designated work products
 Identify and involve stakeholders
 Monitor and control to plan and take action if needed
 Objectively monitor adherence to process and QA products/services
 Review with upper management and resolve issues
KEY {GREEN : Supportive, White: Neutral, RED: Rough Edges}
[5]Jain

17. CMMI Practices vis-à-vis Agility
 “LEVEL 3”
 Maintain as a defined process
 Measure the process performance to support environment
 “LEVEL 4”
 Establish and maintain quantitative objectives for the process
 Stabilize the performance of one or more sub-processes to determine its
ability to achieve
 “LEVEL 5”
 Ensure continuous improvement to support business goals
 Identify and correct root causes of defects
KEY {GREEN : Supportive, White: Neutral, RED: Rough Edges}

18. Agile vs. Plan Driven
[2]Bohem, Turner

19. Why Bother with both?
 Introduce Agility to a
CMMI organization
 “Best of Breed”
