The challenge

Refreshing 10,000+ devices without disrupting engineering workloads

Maintaining a sustained global refresh rate across a diverse device estate

Refreshing a 10,000+ device estate within twelve months required a sustained monthly delivery rate of more than 1,300 devices from the outset. The programme could not rely on a gradual ramp-up while maintaining the required global timeline.

The device population also varied significantly. Engineering workstations, standard corporate laptops and specialist devices required different builds, configurations and migration approaches.

Engineering users were particularly sensitive to migration disruption because long-running computational workloads could be affected by device downtime.

Our approach

A high-throughput global refresh model built around user requirements

HCLTech engaged TECEZE as its specialist delivery partner to execute the global EUC refresh programme. TECEZE combined immediate delivery capacity, persona-based configurations and workload-aware scheduling to maintain throughput while limiting disruption.

The approach included:

Front-loaded throughput

The programme was resourced to achieve full monthly throughput immediately rather than relying on a gradual ramp, supporting the sustained 1,300+ device refresh rate required.

Persona-based builds

Separate build and configuration profiles were maintained for engineering workstations and standard corporate devices, ensuring each user population received an appropriate configuration.

Workload-aware migration scheduling

Engineering user migrations were scheduled around computational workload patterns to minimise disruption to long-running engineering activities.

Globally distributed execution

Refresh activities were delivered across worldwide locations under a single programme standard, providing a consistent refresh experience regardless of user location.

The results: Annual programme run rate

15,600+ device refreshes delivered at 98% SLA

15,600+ Device refreshes delivered at a sustained rate of 1,300+ per month

10,000+ Global estate fully refreshed within twelve months

98% SLA attainment across the year

1,300+ Sustained monthly refresh rate

Global Consistent execution across worldwide

40 locations

Why it matters

The programme demonstrated the ability to execute a high-volume global EUC refresh without treating all users and devices as identical. Persona-based builds supported the different requirements of engineering and corporate populations, while workload-aware scheduling helped minimise disruption to computationally intensive engineering activities.

Sustaining 1,300+ refreshes per month enabled the 10,000+ device estate to be refreshed within the 12-month programme while maintaining 98% SLA attainment and a consistent delivery standard across global locations.

What the client says

“TECEZE delivered the scale and consistency needed to refresh our global device estate while keeping engineering users and their workloads in focus.”
