Digital sovereignty is the common thread.

He led a team of four, was part of the management team (Führungskreis) for many years and set the strategic and operational direction of IT for the three German sites. In ten years at the company he worked with a core of more than 40 external consultants, support partners and service providers across many projects. The work reached into the departments and gave them new impetus, from production and work preparation to administration and the field sales force: - Group-wide IT security concept and group-wide remote-work concept (production, administration, mobile staff, field sales force). - SAP: day-to-day basic administration of the three-system SAP landscape, SAP support and project management for the departments, business processes analysed and improved; SAP migration projects over many years, from a system without enhancement packages to EHP 8. - Production processes and infrastructure optimisation for work preparation, among them a distributed file system across the production sites delivering CNC data to the local machines reliably, securely and fast. - CAD infrastructure with post-processing; PIM infrastructure (product information management). - CRM infrastructure with cross-system data exchange between ERP, PIM and DMS; several projects in the DMS infrastructure. ## Public record (chronological) https://plominski.eu/daniel/history/ is the dated public record of Daniel Plominski: 151 links to registers, mailing-list archives, forums, code hosts, model repositories, profiles and web archives from 2003 to 2026, newest first, each with source, date and his role.
