Dutch Ministry of Infrastructure and Water Management (MINENW)


The MINENW together with the Ministry of Defence and the respective air navigation service providers (ANSPs) has embarked on a journey to redesign some of Europe’s busiest and most complex airspace in order to meet the future demands of Dutch users and stakeholders on the ground. This includes the balancing of many different stakeholder requirements, including the expansion of Lelystad airport, the further development of Schiphol airport and redesign of military training areas in order to facilitate the new F35s purchased by the Royal Dutch Air Force. At the same time, public opinion on aviation is changing. There is greater awareness of the negative impact of aviation, such as emissions and noise. The Dutch Airspace Redesign Programme aims for a major redesign of airspace to cope with the challenges of the future in terms of capacity, sustainability and efficiency.

Before embarking on the airspace redesign programme, the MINENW sought a second opinion on their project principles and project plan in order to validate and fine tune their approach in line with international best practice. The MINENW contracted us to complete this task. This brief case study focuses on the Architecture Principles review.

Role of Egis

Our role in this project was to review the programme principles and high-level plan against industry best practice and our own international experience.

We reviewed the Architecture Principles first as they are the most important document for defining the Airspace Redesign Programme going forwards. The Architecture Principles had already been aligned to The Open Group Architecture Frameworks (TOGAF) methodology, which our team were experienced with, one being TOGAF 9 certified. Our independent review focused on ensuring that the scope of the principles was clear, comprehensive, and would reflect the true needs of the programme.

We concluded that the scope of the principles was sufficient to meet the project’s needs, however we recommended some restructuring for simplicity and to ensure that the needs of stakeholders were appropriately balanced.

The main focus of subsequent recommendations for improvement related to the naming and definitions of the principles. Aligning with the TOGAF methodology and drawing on our experience we recommended that the principles were both specific and measurable. An example being:

  • Original Principle: Design for noise abatement;
  • Recommendation: Must meet or exceed local and national noise policy requirements.

The above example shows how the updated principle is now both specific in its objective and measurable, allowing future requirements to be aligned to the principles and to have specific Key Performance Indicators (KPIs) assigned.

Our review also involved cross referencing the final list of principles to applicable EU and international regulations.


The review resulted in an agreed final set of Programme Architecture Principles being accepted by the MINENW and incorporated into the programme. The principles set a solid foundation for the programme to begin and are currently being used to assist the definition of requirements and performance objectives, with each stakeholder mapping their individual requirements back to an architecture principle.
