Description of duties “Atruvia / HCL International” Role: HCL Notes Banking Support, Domino Administration / Migration / Operations Operations, administration and technical support of the HCL Notes/Domino environment in the Atruvia banking environment on behalf of HCL. As part of an international support team, the focus was on second- and third-level support as well as the processing, management and monitoring of SLA tickets in categories 1, 2 and 3. Duties included the technical analysis and resolution of incidents in the Notes/Domino environment, system administration, and the development and modification of Lotus Notes /Domino applications and LotusScript agents when a programming solution was required. Another focus was ticket dispatching: analysing and assessing incoming tickets, assigning them to the responsible departments and specialist teams, and subsequently coordinating and tracking processing within the agreed SLA periods. There was also direct communication and coordination with subject-matter experts, departments and end customers of the connected banks. In particular, when language or technical communication problems arose within the international support team, German-language customer communication was handled and mediation between customers and technical specialists was provided. Objective Ensuring stable and reliable operation of the HCL Notes/Domino landscape in the Atruvia banking environment and the timely processing of business-critical support cases in line with the agreed Service Level Agreements. Incidents were to be analysed as early as possible and either resolved directly through administrative measures or suitable LotusScript/Notes solutions, or forwarded specifically to the responsible specialist teams. As of: 25.09.2026 (Version 2.10 LITE) including project times Page: 3 of 32 SPO-SOFT EDV Beratung, Dipl.-Ing. Klaus Kano, Tel.: +494532-2767682, Mail: [email], [link] At the same time, qualified preliminary analysis and targeted ticket dispatching were intended to ensure that every ticket reached the technically and professionally responsible department immediately and that unnecessary transfers, processing times and associated costs were reduced. Result Operational Notes/Domino support for the banks served was reliably ensured throughout the entire project period. SLA-relevant tickets were systematically analysed, prioritised, assigned to the responsible departments and tracked through to resolution. Some incidents were resolved directly through administration, technical error analysis and the development of suitable LotusScript agents and modifications to Notes/Domino applications. By directing tickets specifically to the relevant expert and specialist teams, incorrect assignments and unnecessary processing loops were reduced and compliance with the agreed SLA times was supported. Direct communication with the banks and mediation between German-speaking end customers and the international support team also contributed to efficient problem resolution and high customer satisfaction.

As part of this project, the existing active network infrastructure was modernized and made fit for the future. The goal was to introduce a powerful, secure and scalable network and WLAN infrastructure, including a Network Access Control (NAC) solution to improve network security and centralized access control.

At the beginning of the project, a comprehensive requirements analysis was carried out, taking into account the technical, operational and security-related requirements of the hospital sites. On this basis, a technical tender was prepared for new switches, WLAN access points and the NAC solution.

The successful implementation of the project established a modern, standardized and secure network infrastructure that meets the growing requirements for availability, mobility and IT security in hospital operations.

Activities:

• Supporting the tender process, including technical evaluation of offers and bidder evaluation
• Leading and managing the entire project implementation
• Coordinating the project process with internal stakeholders, business units and hospital IT
• Managing external service providers during the implementation and installation of the systems
• Monitoring the implementation, including quality control, project acceptance and defect management
• Coordinating and managing communication between hospital IT and external service providers as part of the NAC implementation
• Managing escalations in the event of technical and organizational challenges
• Ongoing budget monitoring and control of project expenses and additional costs
• Preparing decision papers for management on project changes, additional services and risks

As a Council Member at GLG (Gerson Lehrman Group), the world’s leading expert network, I provide organizations, investment firms, and consulting companies with expert discussions on demand – wherever specialized knowledge in information security, IT governance, and regulatory compliance is needed.

My assessments are based on many years of practical experience in highly regulated industries: from building and implementing information security management systems (ISMS according to ISO 27001), IT risk and vulnerability management, and business continuity (ISO 22301) to the practical implementation of European regulations such as DORA, NIS2, BAIT, and the Cyber Resilience Act (CRA).

The cooperation is project- and discussion-based. I provide decision-makers with a practical perspective gained from real-world experience on cyber risks, security governance, and operational resilience – exactly when it is needed.
