The customer needs services to achieve business outcomes. The service portfolio management process ensures that services enable the accomplishment of strategic goals and objectives as well as tracks the cost and the value of each investment in a service throughout its lifecycle to ensure that it produces its desired returns. The purpose of Service Portfolio Management is ensuring the service offerings are defined and meet the requirements of the customers.
The aim of the ITIL service lifecycle is to provide best practices for IT service management (ITSM). It focuses on helping align the needs of an organization with IT services. The ITIL lifecycle consists of service strategy, service design, service transition, and service operation, along with continual service improvement throughout the process. The ITIL processes, procedures, responsibilities, and specifications are not specific to an organization like those of the SDLC, rather they can be practically applied to establish integration with the company’s IT strategy, providing value and maintaining competency. Essentially, it is a baseline from which the organization can plan, implement, monitor, and measure its processes.
This is the information managed in the service and any supporting information and knowledge including protect, manage and archive it. Technology is main driver for benefit in service management. This may be artificial intelligence, machine learning, the use of mobile platforms, cloud solutions, collaboration tools, automated testing and operations as well as continuous integration / continuous development / continuous deployment solutions[15].
The aim of the SDLC process is product-related. Its goal is to create a product that is high-quality, effective, and cost-efficient. After the product is developed, the SDLC maps the implementation of the software into a live environment. The general methodology of the SDLC typically consists of analysis (of both design and specific requirements), construction, testing, release, and then, maintenance. As you can see, the focus is on the software or product. The SDLC is most commonly implemented using an Agile or Waterfall approach.

The IT Infrastructure Library® (ITIL®) is the world's most adopted and widely-recognised approach to IT Service Management (ITSM). ITIL training exists to support the needs of a business environment. It enables you to reduce your IT costs while delivering better services, by improving the way teams interact and manage your business' IT infrastructure. Used and adapted by industry-leading brands such as Hewlett-Packard, IBM, NASA, British Airways and The Walt Disney Company, studying ITIL can provide many proven benefits.
Naturally, this kind of change cannot start with a blank canvas. The development of IT services should be driven by an awareness of current processes and management practices within an organization. Without this, an IT Service Management (ITSM) process will inevitably waste time, money and effort, giving competitors a chance to lure customers away with more efficient offerings.

ITIL Master Badge (Purple, with the letter M in the middle). Currently in pilot phase this qualification has no training course or exam associated with it. To gain qualification as an ITIL Master, candidates have to have his/her work peer-reviewed by a panel of experts. Once an ITIL Expert has achieved this status, the ITIL Master can wear a lapel pin based on the colour of the ITIL Service Design book, which also has a Gold M in the centre.
