Project Overview: A large-scale rollout of Windows 11 across approximately 10,000 devices within the Devon, Cornwall, and Dorset regions. This rollout is part of a strategic modernisation initiative and has been escalated for urgent commencement. Due to the critical nature of police operations and the sensitivity of the data involved, this rollout requires skilled engineering support with appropriate security clearance. Scope of Work: The engineering support team will be responsible for: On-Site Technical Support (Floor Walking): Daily presence of 4 field engineers across multiple locations (Exeter HQ, Plymouth, Winfrith, and other satellite offices). Engineers must be mobile and able to travel across the region to respond to incidents and support requests. The starting points from the engineers should be varied (for example, 2 engineers starting from HQ in Exeter, 1 starting from Plymouth and 1 starting from Winfrith) Device Replacement & Stock Management: Coordinating secure swap-outs of failed devices using a pre-approved pool of replacement laptops/desktops. Ensuring failed devices are securely retrieved, logged, and returned for repair and reintegration into stock. Maintaining chain-of-custody and asset tracking for all hardware movements. Security & Compliance: All engineers must hold NPPV3 clearance. Reporting & Coordination: Daily coordination with BT Project Manager, who will act as the central point of contact. Engineers must provide daily activity logs, incident reports, and escalation summaries. Key Requirements: Minimum of 4 engineers with demonstrable experience in enterprise OS deployments, preferably within secure or regulated environments. Engineers must be capable of performing full device imaging, BIOS configuration, and troubleshooting of hardware/software failures. Must be NPPV3 cleared and trained in secure handling of police IT assets. Ability to work independently across multiple sites and respond to dynamic support needs. Complexity Justification: This project involves high-stakes deployment, requiring not only technical proficiency but also strict adherence to security protocols. The engineers must be capable of performing tasks beyond basic plug-and-play support, including secure imaging, diagnostics, and sensitive asset handling. The operational impact of failed upgrades is significant, and the support provided must ensure continuity of police services
