Building a Value-Driven Portfolio for Strategic Alignment 

Fluvius, the Flemish multi-utility grid operator, is in the midst of a major transformation. With a broad strategic agenda and hundreds of initiatives on the horizon, the ambition is clear: establish a portfolio approach that is streamlined, value-focused, and capable of steering both short-term priorities and long-term investments.

The Ambition

Fluvius wanted to strengthen its portfolio governance so that every new initiative would follow a clear intake process, investment decisions would be taken with value and strategy in mind, and the organization could confidently balance a high volume of projects against budget and capacity constraints. To achieve this, a governance approach was needed—one that ensures consistency and prioritization, while remaining lean and agile enough to adapt quickly to changing circumstances and unforeseen challenges.

Our Contribution

AdaptX supported the Portfolio Office in turning this ambition into practice. Together we co-created a new governance flow that connects strategic intent to portfolio execution. Key enablers included the introduction of Lean Business Cases to put outcomes and value at the center, the adoption of iterative budgeting with staged go/no-go decisions, and the embedding of change management practices to bring stakeholders along. By piloting these approaches and gradually refining them, we ensured that improvements were not one-off fixes but part of a continuous, scalable way of working.

To strengthen financial governance, a mechanism was also introduced—providing a uniform way to handle budget escalations when initiatives require additional funding, ensuring fairness and consistency across all cases.

The Impact

The portfolio process has begun to shift from a constant influx of initiatives and change requests into a structured flow with clear governance. New initiatives now enter through one uniform intake route, where priorities and budgets are defined upfront. The Portfolio Office acts as a gatekeeper, ensuring that initiatives aligned with strategy and capacity move forward. Through Lean Business Cases, iterative budgeting, and active stakeholder management, initiatives are followed up in cycles, allowing value to be validated and adjustments to be made along the way.

After starting with pilots, this approach has been scaled up to a broader level of portfolio oversight and higher-level decision-making. The current focus is on consolidating these practices and preparing for the next step: scaling further across the organization. It is an ongoing journey—embedding agility and continuous improvement into Fluvius’s transformation, and building the governance, mindset, and processes that will enable a full shift towards value-driven portfolio management.
