A strategic operating model engagement within the Home Office’s Shared Application Services workstream, shaping the Future Mode of Operation in a complex multi-supplier environment and laying the foundation for long-term service transition at scale.
Within the Home Office Migration and Borders Technology Portfolio, Mastek joined Project Optimus alongside a “Rainbow Team” of the department’s top application service providers to help define a new operating model for Shared Application Services.
The supplier ecosystem was split between digital-oriented providers aligned to Agile and DevOps ways of working and heritage suppliers protective of legacy ITO models. The task was to help shape a coherent future operating model in the middle of those competing assumptions.
Recognised as a trusted advisor to the SAS Programme Manager, I helped position Mastek as a collaborative, digital-first voice within the Rainbow Team. Working closely with similarly minded suppliers, I shaped thinking around squad-based delivery teams, blended ITSM, Agile, and DevOps practices, integrated toolchains, and the business change activities needed to move from inflexible legacy ways of working toward a product-oriented model.
The Mastek-influenced Future Mode of Operation secured buy-in from project leadership, the wider supplier Rainbow Team, and DDaT ExCo. The high-level model was approved to proceed to detailed elaboration and is being used as the basis for operating model design, implementation, and transition from as-is service provision to the target model. In practice, this laid the foundation for a 10-year transformation programme that increased the proportion of applications managed by Shared Application Services from 10% to 80%.
