Today, we could search and access everything by force of internet. Many of things is explored and we can reach them. There is no need experience to experimentation. As a different, no need to explore America again :)
My words will be for corporate companies and project managers. If you doesn't take advantage of these frameworks, you should think one more time :) Achievement is so close. Just implement these framework or methods which is suit for your business.
ITIL
ITIL (IT Infastructure Library) is one of the best example series of service management.
ITIL was developed by England Office of Goverment Commerce. ITIL is like a bridge between customer , provider , IT department , and users. Today, ITIL is in use and valid business standard in whole world.
ITIL is a best practice library. This library bases on correct service, correct customer, right architecture for customer's penury , minimum risk and maximum performance. This library is not show to what should i do directly because all company has different service and this service has need different process.
ITIL is defining service management concepts, guide to resuming service and a book which is telling about service details for users. ITIL is not a absolute solution but you can be professional with ITIL service management methodology. Methodology should be defined with regard to organization structure, technology and culture.
ITIL has a life cycle. This life cycle include
- Service Strategy
- Service Design
- Service Transition
- Service Operation
- Continual Service Improvement
Lets explation to briefly life cycle steps:
Service Strategy: Service Strategy (SS) include how should determine to IT service management's strategy. This scope contains decide to market place, designate to customers, decide to source and limitation. Main goal of this step is be an unique about offering service.
Service Design: Service Design care about service constraints. At the same time service design is focusing on how should design to services and these services accounting position. Also service design is being interested prudential service.
Service design has some of package. The package are like a outcome to services. These packages are developing to service, testing , generalizing and all of operation details.
Service Transition: Service Transition (ST) is leading to how designed service should to go into action. Service transition is a critical point of service life cycle. Service transition is including service design package development, testing and loading. Also it has existing services innovation.
Service Operation: Service operation (SO) is based on efficient and effective service management. Because of this part customer can understand to value of services. Also service operation is a part of reporting to service performance.
Continual Service Improvement: Continual service improvement should be integrated with all life cycle. Improvement should be constant activity. According to service operation's performance values, continual service improvement decide to changing on service strategy and service improvement.
For better explanation, lets see a short video:
Now we can explain to COBIT.
Cobit (Control Objectives for Information and Related Technology) is based on IT management's target which should reach to system.
What is Cobit's differences from ITIL and CMMI
The biggest differences , cobit contains all of the IT functions perspective. As a different explain, cobit has 34 process which is include all of IT management. Because of this reason, cobit doesn't focus to IT process. Cobit focuses on IT steering. Another difference is, cobit doesn't include to detailed solution methods. Cobit occurs control targets and these targets includes explanation of best practice. But cobit doesn't offer any method, template or design.
You can see briefly to cobit 34 processes. There are 4 main title for these processes.
All of these processes have these stages:
Process definition: Generally process definition describe whole system. It includes
- Process goals
- Events
- Efficiency
- Privacy
- Manufacture
- Performance measure
- Source management
- Practice
- Knowledge
- Groundwork
Management Guide: This part focuses on process management. Management guide includes these information:
- Process input and output
- Role and Responsibility in process
- Process goals and measurement criteria
Maturity Model: Cobit provides to comparing company's maturity with another companies. For this model there is a scale between 0 - 5.
- 0 (Undefined): Company doesn't aware of management process.
- 1 (İrregular): Company realizes management process but doesn't apply
- 2 (Reproducible): Company applies to management process but doesn't define to principal of management.
- 3 (Defined): Process was be defined and applied.
- 4 (Mensurable) Process is measurable.
- 5 (Optimal): Process to be developed permanently
Also cobit answers these question:
- Which process should we create?
- Which steps should be in these process?
- How should slipt up role and responsibility?
- How could measure our activity?
CMMI
CMM model was developed from Carnegie Mellon University with UK Defense Department at 1989. This model is a template model which describes important piece of software process. CMM creates a path which goes to discipline. Main principle of CMM evaluates to software process for much be mature. CMM provide to compare other tools. CMM defines five maturity levels and 17 key processes. SEI describes different CMM models. They are:
- Software enginerring
- Integrated product development
- System engineering
- Procuration process
Nowadays many of companies are demanding third level CMMI certification. These levels:
- Inıtial
- Repeatable
- Defined
- Managed
- Optimizing
TOGAF
Togaf is a common consortium which leader companies (IBM, NEC, HP, SAP...) share their experiences. Togaf be gone on developing with more than 300 companies. This framework supports creating international corporate architecture. The Open Group Architecture Framework (TOGAF) helps to companies for create a methodology and developing solution strategy. Corporate architect and managers could be successful by the help of TOGAF's power.
TOGAF and ITIL
CMMI and TOGAF
CMMI is a process enhancement approach which could increase to performance. CMMI could used in a project or in a part of project or in whole organization. CMMI explains to what should do but it doesn't explain to how should do.
In Togaf management architecture
There is a providing which company could make a realistic and sustainable decision. Togaf helps to company for effective variation management. Togaf supports a associate language between company's different department and different application.
