How Hitachi Energy Manages Requirements at Scale in Large Infrastructure Project

How do you manage requirements when projects span multiple systems, stakeholders, and constantly evolving inputs?

At Taipuva Polarion Days 2026, Hitachi Energy shared a behind‑the‑scenes look at their journey of implementing Requirement Management and Polarion X across their HVDC business — where scale and complexity quickly turn traditional approaches into bottlenecks.

Their speaker, Johanna Varnander, walked through how they are moving away from document‑based ways of working towards a more structured and scalable approach — built on a shared information model, governance, and collaboration across teams.

But as with all large transformations, the story wasn’t about tools alone. It was about changing how requirements are created, managed, and understood across the organisation.

When requirements stop scaling

A key challenge highlighted in the session is something many organizations recognize: document‑based approaches can become too extensive and complex to handle as projects grow. As requirements increase, so do:

• dependencies between systems
• communication needs between teams and stakeholders
• challenges in maintaining traceability and consistency

Scaling requirements management is not just about handling more data — it’s about managing relationships between requirements at a much larger scale.

From fragmented processes to a shared model

Hitachi Energy’s approach focuses on building a common way of working across the organization. This includes:

• moving towards a unified information model
• reducing unnecessary customization to keep processes manageable
• strengthening governance to ensure alignment across teams

They also highlight practical challenges along the way — from handling large requirement imports to balancing tool maturity and integration needs.

Why you should watch the full presentation?

This session offers a candid, real‑world look at what happens when requirements management is pushed to scale. The team shares insights that are directly relevant for organizations facing similar challenges, including:

• why document‑centric approaches start to break down
• how scaling requirements introduces new types of complexity
• what to expect when transitioning to structured requirements management
• how governance and collaboration become critical success factors

These insights only scratch the surface of what Hitachi Energy covers in the full session. If you want a practical look at how requirements management evolves in large infrastructure environments — and the challenges that come with it — this is a session you should not miss.
