1 OVERALL PROJECT SCOPE

The NATO Communications and Information Agency (NCIA) located in The Hague, The Netherlands, is providing technical support to the NATO HQ Cyber and Digital Transformation (CDT) Division to provide architecting expertise to support addressing Architecture Capability Team (ACaT) POW, development of Reference Architectures (RA) and support integration of RAs in Architecture for Digital Technologies within the Alliance (AIDA).

2 TASKS FOR ENTERPRISE ARCHITECTING

The general services to be provided are delivery of enterprise architecture outcomes:

• resulting in deliverables from the Architecture Capability Team ACaT POW, including attending the quarterly meetings (1 at NATO HQ, 2 in other locations).
• resulting in integration of RAs in the AIDA, with specific focus on RAs provided by nations.
• related to leading and supporting architecture sprints in coordination with other stakeholders.
• allowing for cohering already existing architectures in light of the AIDA, and of the principles developed in the EA Policy, identifying architectural diagrams that could be re-used within the AIDA.

3 ACTIVITIES AND DELIVERABLES

3.1 Activities (Non-Deliverable)

The Contractor shall perform the following activities in support of the deliverables defined in Section 3.2. These activities are not considered deliverables in themselves.

• Preparing ACaT meetings, setting agendas, engaging with representatives, manage action lists, prepare working papers and presentations, and orchestrate required SME expertise.
• Investigating and cohering Digital Interoperability Standards (standards with DPC as tasking authority) and Interoperability Profiles against what is reported in the NATO Interoperability Standards and Profiles (NISP).
• Carry out modelling in Archi such RAs focusing on the interfaces and interoperability points, identifying potential conflicts or duplications across the 5 interoperability layers defined in the Digital Interoperability Digital Interoperability Framework for the Alliance (DIFA).
• Cohering already existing architectures in light of the AIDA, and of the principles developed in the EA Policy, identifying architectural diagrams that could be re-used within the AIDA.
• Lead and support architecture sprints in coordination with other stakeholders, to ensure that the team delivers against the objectives of the sprint, within the allocated time and that the delivered products can be included in the AIDA.
