Letové prevádzkové služby, š.p. provide air navigation services within the airspace and selected airports of the Slovak Republic. Indirectly, all of the passengers are their clients in airlines passing above Slovakia. Since 2004, the company has been representing Slovakia within the project of Single European Sky and is responsible for management of air traffic at five airports and administration of more than XX radar stations and navigation systems.
Support of air navigation services in records and solution of events was provided by combination of paper and electronic systems (log book, several heterogeneous and often duplicate systems). However, the situation was administratively demanding and unsustainable in the long term. It turned out necessary to shift to a new, more flexible system able to provide relevant information to ensure the air traffic – air traffic / operation information system.
Technical coordination centre (Internal call centre) of Letové prevádzkové služby and the whole company operate in the 24×7 mode. 5 operators provide information for approximately 85 solvers dislocated throughout Slovakia to ensure trouble-free operation of aviation systems.
Goals and requirements
An important aspect was to harmonize aviation terminology with standard IT terminology in transition to PosAm Servio. Particularly in terms of definition of individual operation services and description of (not only) IT environment characterized by long equipment life cycles (up to 25 years), openness of PosAm Servio has turned out to be the key feature.
Fundamental requirement has certainly been to ensure high system accountability and availability, since the Operation information system is operated in this “safety critical” segment where you have no possibility to stop a running process.
With respect to the mentioned parameters, it was necessary to implement PosAm Servio step by step while maintaining (or effectively redesigning) the original processes and availability of the original as well as the new systems for selected users. To maintain data integrity between the two systems was a must.
Introduction of PosAm Servio was preceded by a detailed analysis and preparation of system configuration.
The first step was to implement basic version of the system in order to primarily verify functionality and to familiarize with the solution. Then service management model and catalogue of services were created. Definition of business and technical services and their mutual relations, quality levels of provided services (SLA, OLA), metrics for their evaluation, performance capacity indicators, scope of individual service provision and so on. The project was specific with a high number of services (dozens) provided and managed using PosAm Servio for a relatively low number of users (350). An advantage was integrated models for catalogues of services and quality management, significantly contributing to streamlining and accelerating the works in this stage.
The second step was to fill the TZL (CMDB) database with information and to set configuration management. The contents included information on facilities of engineering infrastructure, their mutual relations, data on solution groups, organizational structure and the like. An advantage in data recording were the dynamic data structures and relations within CMDB which provided sufficient flexibility, and the extent of data turned out to be no problem for records of technical equipment with high levels of complexity and multiple redundancy (e.g. radar and navigation systems, telecommunication equipment).
In order to eliminate the risks, the overall implementation was divided into several stages with careful evaluation of individual aspects after each stage and modification of implementation process according to collected information. Speed of implementation was significantly supported by the PosAm Servio solution out-of-the-box functionality which allowed keeping up with the determined deadline to start the full system operation within 7 months from project initialization. An important part of the solution is reporting which provides comprehensive information on all key parameters as well as allows evaluation of fulfillment of required objectives.
Results and benefits
Elimination of double records (paper records, records for statistic purposes in electronic form have been replaced by centralized records in PosAm Servio).
Automation of many activities (events planner, calendar functions, automated responses, batch processing, pre-defined forms and many more) streamlined routine activities and increased performance efficiency in provision of technical support. Quality control and automated corrective activities constantly monitor compliance with the set quality levels of business as well as technical services. Well-arranged records of assets and engineering infrastructure in TZL database help better evaluate individual events in their context and subsequently proactively prevent potential incidents and problems. Continual user satisfaction evaluation has confirmed increased satisfaction with provided services.
“Implementation of PosAm Servio in the context of ITIL recommendations and introduction of services helped us better understand our own environment and established processes. Creation of service catalogue allows streamlining the work, better status monitoring and evaluation of performance of operation service provision.”
Main benefits of the solution
- Paperwork in dealing with events reduced by 40%
- 98% of reports are solved within the SLA agreed
- 98,5% of users have expressed their satisfaction with the quality of services
