As a central player in the digital transformation of the Belgian French-speaking public sector, Client is involved in a variety of areas such as:

  • Transversal Traceability (SIEM / SOC)
  • Supply Chain & Subcontractor Management (MAP)


Activities

Main responsibilities:


  • Scoping & planning: define scope, objectives, milestones, deliverables, detailed planning, workload plan and communication plan for each project.
  • Budget & financial management: establish and monitor budgets, negotiate envelopes with sponsors, produce variance analyses (costs incurred vs. planned) and guarantee ROI control.
  • Risk & dependency management: maintain a structured RAID log, manage inter-project dependencies, anticipate critical paths and trigger mitigation plans.
  • Operational management and reporting: lead COPIL, workshops, COPOR and CODIR, consolidate management reporting and formalize cost-deadline-quality trade-offs.
  • Coordination of the cybersecurity component: steering, in conjunction with SPOT, the security floor projects (SIEM/SOC traceability, RTO/RPO/DRP/BCP continuity) and ensuring their integration into the overall schedule.


Methodology & tools: mobilize adapted approaches (V-cycle, Agile, hybrid) and the PMI/PMBOK and PRINCE2 standards; produce and maintain structuring documents (project charter, PMP, WBS, RAID log, decision register); set up rituals (stand-up, milestone reviews, retrospectives)
