CMMI vs ITIL


CMMI and ITIL are two distinctly different maturity models. The fundamental difference between CMMI vs ITIL is that while CMMI focuses on software process maturity, ITIL is broader in scope and focus on all areas of infrastructure, including software and hardware.

Origins

Carnegie Mellon University (CMU)’s Software Engineering Institute developed the first Capability Maturity Model (CMM) in 1990, and followed it up with the Capability Maturity Model Integration (CMMI) that integrated multiple CMMs.

The United Kingdom’s Office of Government Commerce (OGC) developed the IT Infrastructure Library (ITIL) in 1986 to provide guidance for service management. These set of guidelines has since then emerged as the international de facto standard framework of best practices for IT service management and infrastructure. ITIL originated as a collection of books, each covering a specific practice within the IT service management.

Scope

CMMI is a proprietary maturity model that consists of the best practices applied in the development of software, derived from the industry. CMMI segregates the best practice knowledge into five levels: initial, managed, defined, predictable, and optimizing, based on the expertise of the organization in applying such best practices. Each level progresses to higher standards and addresses the development and maintenance of products and services through the product life cycle from conception through delivery and maintenance.

ITIL is a set of comprehensive and coherent codes of best practices, and ITIL scope extend to controlling and managing all aspects of IT related operations.

Comparing CMMI vs ITIL, ITIL does not rank or grade the organization based on the extent or level of its compliance. ITIL instead offers three popular certification levels for practitioners: foundation, practitioner and service manager, based on the extent of competency of the individual in ITIL. ITIL is a non-proprietary tool that encourages the private sector to develop services and products such as training, consultancy, and tools to support ITIL.

Application

The basic difference between CMMI vs ITIL lies in application. While CMMI is focused toward software development, maintenance, and product integration, ITIL is broader in scope and provides a framework for IT service management and operations including a hardware life cycle.

CMMI is geared specifically to software development organizations and focuses on continuous improvement, whereas ITIL addresses IT operations issues such as security, change and configuration management, capacity planning, troubleshooting, and service desk functions.

While the application of CMMI helps the organization gain competency and expertise in software or product development, ITIL applications help align the entire IT process and resources of the organization to business processes.

Structure

CMMI is a prescriptive approach that orders process areas along a maturity model with maturity levels. A CMMI model is not a process but a description of effective process characteristics.

Unlike CMMI, ITIL is not prescriptive and orders the processes in sets. CMMI for instance, recommends requirement analysis but does not specify how to do a requirement analysis. ITIL on the other hand, provides solutions on how to undertake the requirement analysis.

Similarities

Both CMMI and ITIL are process maturity frameworks that follow a similar and structured approach. Both emphasize development of processes to improve product development and customer satisfaction and support the coordination of multi-disciplinary activities related to a project.

Although both CMMI and ITIL are similar in structure, the amount of duplication is, however, small and there is no contradiction between the two models, making it possible to apply both CMMI / ITIL models simultaneously in an organization. CMMI is the de facto quality standard for software development, integration, deployment, and maintenance processes in organizations and ITIL is the first choice of organizations for standards related to operations and the infrastructure side of IT.

Implementation of CMMI / ITIL also aids organizations in reducing the cost of quality, improve turnaround times, and arrive at a precise estimate of efforts required that helps in costing products.

Resolution 2009

Entry for January 07, 2009 - Resolution 2009 magnify

From young, I have been setting targets and goals and it has been a few fruitful years. Though some of the years, the target was over-set, which causes me to few a bit down for not achieving it. There were also times, that it was fruitful and able to push me forward very well. I remember there were time that I didn't even know where I kept my resolution. Whatever it is, resolution is a tradition to me and I would go around asking people what their resolution is. Funny but interestingly, most people do not have one or a very vague one.

Here is how you can do it most effectively as far as I am concern. I am no expert but I must say that I have enough experience of it over the past 10 years to know what to do to setup your yearly resolution

1. FOLLOW what your heart tells you. Take time to meditate, think, think and think. Talk to yourself on what really makes you happy and what really propels you forward and make you feel good. Your heart must buy what your head says. Think with the very end in mind. I know this is tough, but when you set this year resolution, think as far as possible what would the end result be from your goals and actions this year. Begin with the end in mind, says Covey

2. THINK big, start small, walk persistently...

3. WRITE it down... anything you do, the one thing you MUST do is write it down. Somehow it helps your brain to stick the info in better.

4. Get an accountability partner to help ensure you follow up

5. Work on it, don't drift. Stick to the wall and look at it everyday. Ensure you move inch by inch towards it. At least millimeters.

There is a lot of good expert out there that have written great books about it, but if you are really serious about it, get excited and go for your goals that you have set out to do :)

The Last Lecture by Randy Pausch



I got a book, a small book for a run-down price during the MPH sales near my house. I think I have got more than what I have bargained for. For a few reasons, reason no. 1 is that it is small enough for me to finish reading within the appropriate time frame. I found that this days, I do not have the endurance to finish a book. It happened when I try to read the last thick book, that is, one of the Lord of the Ring book. Even when I tried to read the Harry Porter book, I couldn't finish one. So having bought and completed Randy's book is one of my personal achievement, that yes, I am still able to find the concentration to finish a book.

OK, moving forward, like to share with you what I have learned from the book, I figured that there will be a couple of people who is like me, who will always try to look for synopsis of the book rather than going through the whole book. The story begin frankly with our Professor Randy Pausch who has been diagnosed with cancer. The story goes on to tell us how he thinks life is all about, how he navigated it through and how he summarizes it for the benefit of his students and also his family in his last lecture in Carnegie Mellon University.

A few of the things that strikes out in the book or lesson learned are

1. Life meaning is about fulfilling your childhood dream (well, yes, that is what Randy has achieved)

2. He throws in a couple of adventure and the lessons that he had learned throughout life. I remember especially the one on head-fake.

3. It is also one of his happiness to be able to enable other people's dream, which is what a lecturer's life is all about. Training the students for the coming future in his field of expertise, that is the virtual reality.

4. His second last section is on how to life your life, that is, to Randy how he had live his life or his life lesson thus far. He is telling us his way that he thinks best of living it. No argument there with our professor.

5. His final remark is a bit touching. It is mainly for his wife and his kids, which he may not be able to see very much of in the time of his writing of this book. Nevertheless, he has given much thought and communication with his wife. The think about him is that he views communication, jovial and his choosing not to succumb in sadness or depression really sticks out strongly for him.

The book contains some photos which shows that the professor in his 40s still look very boyish and handsome and has been able to exude a strong sense of friendliness and influence in the place he works and people around him. The way his think and a piece of his thought throughout the book gives us a fresh insight of a dying man with a strong and firm battling spirit for the betterment of his family is really an inspiration to me. Not only that I am not facing such issues, but I am living my life so much less 'treasured' compared to him. Well if one thing Randy did in this book is to tell me to live my life to the fullest and in every moment of it. Live my life to the very minute of it, with the people that I treasure most.

Go get the book, the author is already dead now, that is, somewhere July/August 2008 this year. However he will always be remembered, at least by me. Go 'google' this famous name out or get a hand on his book. Have a nice day :)
