We followed a dual approach that combined the strategic design of the to-be operating model with a parallel pilot in one of the investment management teams for real-life validation of core components. The focus was on developing the organization's ability to quickly and safely adapt by building a 'change muscle' that enables the organization to identify and respond to new transition themes at high speed. In shaping the to-be operating model, SparkOptimus addressed three main dimensions - ways of working, governance & steering, and organizational structure. The parallel pilot helped stress-test critical design components and bring the to-be operating model to life for operational teams, adjacent colleagues, and senior management. SparkOptimus co-shaped PGGM IM's to-be operating model, which included specifying test-and-learn ways of working, designing cross-functional collaboration models, future governance structures, and detailed the scaling approach.
