Dear followers,

I'll try to give information about ITIL,COBİT,TOGAF,CMMI and the relationship between them.

First I give information about ITIL: ITIL advocates that IT services are aligned to the needs of the business and support its core processes. It provides guidance to organizations and individuals on how to use IT as a tool to facilitate business change, transformation and growth.

The ITIL best practices are currently detailed within five core publications:
ITIL Service Strategy, ITIL Service Design, ITIL Service Transition, ITIL Service Operation , ITIL Continual Service Improvement.

These five volumes map the entire ITIL Service Lifecycle, beginning with the identification of customer needs and drivers of IT requirements, through to the design and implementation of the service and finally, the monitoring and improvement phase of the service.

COBITs are now in,you think :Why am I a huge fan of COBIT?

COBIT is relevant- the goal is to deliver value
COBIT still focuses on information.
COBIT is not just for the big companies.
COBIT is a framework that looks beyond just processes.
COBIT is a great reference for process owners
COBIT has a goals cascade that is flexible and useable
COBIT has a product family that is consistent, like a single playboo
COBIT can be incorporated with other frameworks
COBIT is the “middleware” between Governance, IT, and Assurance
No more control objectives

Whether you’re a board member, executive, auditor, or IT Operator, do yourself a favor and learn more about it.

Do you wonder TOGAF then , TOGAF is an architecture framework - The Open Group Architecture Framework. It enables you to design, evaluate, and build the right architecture for your organization.

The primary reason for developing an enterprise architecture is to support the business by providing the fundamental technology and process structure for an IT strategy. This in turn makes IT a responsive asset for a successful modern business strategy.

Today's CEOs know that the effective management and exploitation of information through IT is the key to business success, and the indispensable means to achieving competitive advantage. An enterprise architecture addresses this need, by providing a strategic context for the evolution of the IT system in response to the constantly changing needs of the business environment.

Furthermore, a good enterprise architecture enables you to achieve the right balance between IT efficiency and business innovation. It allows individual business units to innovate safely in their pursuit of competitive advantage. At the same time, it assures the needs of the organization for an integrated IT strategy, permitting the closest possible synergy across the extended enterprise.

The technical advantages that result from a good enterprise architecture bring important business benefits, which are clearly visible in the bottom line:

A more efficient IT operation:
Lower software development, support, and maintenance costs
Increased portability of applications
Improved interoperability and easier system and network management
Improved ability to address critical enterprise-wide issues like security
Easier upgrade and exchange of system components
Better return on existing investment, reduced risk for future investment:
Reduced complexity in IT infrastructure
Maximum return on investment in existing IT infrastructure
The flexibility to make, buy, or out-source IT solutions
Reduced risk overall in new investment, and the costs of IT ownership
Faster, simpler, and cheaper procurement:
Buying decisions are simpler, because the information governing procurement is readily available in a coherent plan.
The procurement process is faster - maximizing procurement speed and flexibility without sacrificing architectural coherence.

Finally I tell CMMI , Capability Maturity Model Integration (CMMI) is a process improvement approach that provides organizations with the essential elements of effective processes.

CMMI stands for "Capability Maturity Model Integration". It's the integration of several other CMMs (Capability Maturity Models). By integrating these other CMMs, it also becomes an integration of the processes and practices within the model in ways that previous incarnations of the model(s) didn't achieve. The CMMI is a framework for business process improvement. In other words, it is a model for building process improvement systems. In the same way that models are used to guide thinking and analysis on how to build other things (algorithms, buildings, molecules), CMMI is used to build process improvement systems.

It is NOT an engineering development standard or a development life cycle. Please take a moment to re-read and reflect on that before continuing.

The CMMI helps us understand the answer to the question

How do we know?
How do we know what we are good at?
How do we know if we’re improving?
How do we know if the process we use is working well?
How do we know if our requirements change process is useful?
How do we know if our products are as good as they can be?

The most important part now, ITIL,COBIT,CMMI,TOGAF relation between,

Analysing The Relation in Between ITIL, Cobit, Togaf and CMMI

The relation of enterprise architecture with some wellknown management practices in each of these areas:

1.IT Governance:COBIT

2.IT Service Delivery and Support:ITIL

3.IT Implementation:CMMI

4.A framework for developing an enterprise architecture:TOGAF

COBIT is a framework for the Governance and Management of the Enterprise IT covering the Enterprise End-to-End including the business processes from the board of directors to the IT operation levels, enabling a holistic approach based on 7 enablers :
- Principles, Policies & frameworks),
- Processes,
- Organizational structures
- Culture, Ethics & Behavior of the Enterprise stakeholders (including the Board, Employees, Management, etc)
- Information,
- IT (Services, applications, infrastructure)
- People, skills & competencies (HR management)
while ITIL is a framework of best practices in IT Service Management (covering the IT side only) and focused on processes only which doesn't allow any holistic approach.

ITIL could be seen as the way to manage the IT services accross their lifecycle while COBIT is about how to Govern the Enterpise IT in order to generate the maximum creation of value by the business, enabled by IT investments while optimizing the risks and the resources.

This is definitely two very different things which are complementary but with a huge difference in terms of scope and objectives

CMMI and ITIL are two distinctly different maturity models that can complement each other when used together. The fundamental difference between the two is that CMMI is a method of process improvement for software development, while ITIL focuses mainly on IT issues.

Business architecture is addressed by TOGAF but not by ITIL and,similarly, IT services are addressed by ITIL but not by TOGAF.The other elements are covered in both frameworks,

albeit that the level of detail differs for each framework. In summary TOGAF gives you all you need to build the perfect IT solution and monitors the actual building, but provides no

guidance on how to actually deliver IT services. ITIL gives you allyou need to deliver IT services perfectly.

While TOGAF adds structure for enterprise architecture, processes and techniques, COBIT puts TOGAF into context by relating architectural processes to all other IT processes. And COBIT, through RACI charts, adds responsibilities for TOGAF, helping organizations implement TOGAF and connect it to broader IT processes. To complete the circle, COBIT also adds key performance indicators for TOGAF.
