3 Introduction The main purpose of this service catalog is to document National Help Desk, of A2I Program s for supporting various IT services and establishes the basis for other service management components. In essence, it defines what services are available, what to be delivered and whom the address from the IT delivered services and aligns those services with the business goals and needs. It can be a baseline for a Level Agreement, or even replace it in some cases. It also becomes the basis for documenting procedures and processes in National Help Desk. Background Information In order to strengthen the fundamental government responsibility that is providing information and services aimed at improving the social and economic welfare of its citizens, Access to Information (A2I) Programme of Prime Minister s Office has been working to develop a centralized ICT enabled platform that could accumulate all necessary initiatives taken for the benefits at citizens end. With the consistent and ever growing public necessities it is now very much important to improve the hitherto practiced service delivery model to counter the impact of widespread outdated manual processes, resistance to change by civil service staff and a lack of transparency that still frustrates citizens in their attempts to avail government information and services. Therefore, with an aim to improve citizen relations and satisfaction on service provided for both Government agencies and mass people connected to the information services, A2I has planned to establish a 24/7 IT Help Desk Center which will provide adequate information to users at their request for having support to use/operate/access/improve all national e-solutions related to all e-services developed or organized by A2I for 24 hours in a day and 7 days in a week and hence nominated Mango Teleservices Limited as Help Desk Partner. s will cover both technological and operational responses and incident management process integrated business model automated or simplified, where the ultimate users will receive their answers and clarifications to their queries and complaints within the shortest possible time using the better technology and communication.

Mango will deploy necessary number of help desk agents based on service catalog designed, concurrency projection and service span assessed. ITSM/ITIL and service catalogs IT Management (ITSM) is the framework laid out by the IT Infrastructure Library (ITIL). ITSM/ITIL originally started in the United Kingdom but has spread rapidly in recent years through many IT organizations around the world. The service catalog is a primary tool in building National Help Desk ITSM framework. However, even if this is not fully implementing ITSM, the benefits of a service catalog are quickly apparent. 4

5 Developing the service catalog National Help Desk is going to have to put on its thinking caps to develop its service catalog. In order to first identify the services, we started looking into work from the perspective of the core business purposes. Then, looked at what IT offerings support those services. After the core purposes, moved into those supporting areas that IT also serves, such as administrative or general organizational support. The entire service catalog is built from the customer s perspective. Some services can be further broken down into subservices as well if needed.

Description This is a high-level description of the service written in language customers can understand. Support Point Listed where should the customer begin an inquiry or report problems regarding the service. Responsible Manager List the contact person responsible for the service. Customers/Users What set of customers (specific or general) utilizes this service. Detailed Specifications Some items may not require all of these elements, but possible elements to include in specifications are: o Inputs hardware, software, infrastructure, customer inputs, etc. o Outputs final products viewed from a customer perspective o Default items always included o Optional items the customer may request or pay extra for o Excluded items which are never included o hours of availability o Up-time and service availability goals 5

6 o o o o Support provided Performance standards for the service Customer procedures for starting, changing or ending the service Charges (if appropriate) Form and structure of the service catalog The service catalog is prepared based on a formatted tabular format as prescribed in ITIL. In addition to the detailed information for each service, the service catalog includes the following pieces of information: Title Version Last Revised Date Introduction and description of purpose Description of IT organization as a whole The Catalog Template, which follows, provides some examples for developing a list of services and writing up each individual service. Benefits of this service catalog The benefits reaped by a service catalog depend somewhat on the purpose it's intended to fulfill in the scope of Help Desk. If the service catalog's design includes measures of success for the service, it can provide a baseline for performance metrics that help identify areas that need improvement. A service catalog can also assist support help desk managers in defining the scope of support in an organization, as it qualifies the incidents. It can even help identify priorities for incidents based on their impact to business functions. From a customer perspective, a well-marked service catalog helps users identify what services are available to them and what the boundaries might be. Only those users requiring a different level of service will need to have an SLA and that SLA will only need to define what items differ from the standard service catalog. For some internal support organizations, a service catalog may be all that is ever needed. Building procedures from the catalog After developing the service catalog, the logical next step is to define procedures for each service. The service catalog itself provides the support desk with contact information as well as performance standards to monitor. The service catalog is also a useful tool for looking at incident classifications. After all the work in building the service catalog, procedures are the natural next step to documenting the work of the support desk. The procedure should first look at what questions will need to be gathered on input of an incident or request. Response time standards and 6

7 escalation procedures will also flow naturally from the service catalog. If the incident or request cannot be solved at the support desk, procedures will use the contact information to initiate an escalation to second level technicians. However, it is important to note that the work of the service catalog is never really complete. Ongoing maintenance, review, and revision will be necessary for the service catalog to continue to play a vital role in the National Help Desk IT service management.
