Working with central government, local authorities, and arms-length bodies, 6B provides end-to-end support across API development, system integration, data exchange standards, cloud connectivity, and platform modernisation. Whether you are integrating case management systems, enabling inter-department data flows, or building new APIs, we help you deliver reliable, standards-aligned interoperability at scale.
We make interoperability simpler – reducing complexity, accelerating delivery, and enabling your digital solution to work in harmony with the systems that matter most.
Understanding Interoperability and Integration in Government
Government services rely on complex technology landscapes: long-standing legacy systems, siloed data, distributed teams, and evolving policy and operational pressures. Many public services require information to flow securely between departments, agencies, third-party providers, and shared platforms — all while meeting strict requirements for privacy, security, accessibility, and auditability.
Interoperability in this context depends on open standards, clear data models, strong governance, and secure, scalable integration patterns. These may include RESTful APIs, event-driven architectures, secure file transfer, message queues, or cloud-native integration platforms. Government organisations must also align with UK GDPR, NCSC guidance, and internal departmental standards.
6B supports organisations in designing and delivering integration architectures that are maintainable, secure, and aligned with cross-government interoperability priorities. Our teams work across diverse platforms, from legacy line-of-business systems to cloud-ready applications, ensuring data flows are efficient, safe, and future-proof.
Our Interoperability and Integration Process
We begin with a comprehensive assessment of your systems, data flows, operational needs, and regulatory requirements. This includes understanding existing architecture, data standards, APIs, dependencies, and integration pain points.
Our architects then design an integration approach that aligns with your organisational context. This may include API-first strategies, microservices, event-driven messaging, canonical data models, or hybrid cloud integration patterns. We focus on security, maintainability, and scalability from the outset.
During development, our engineers build secure APIs, connectors, data transformation pipelines, and integration microservices using modern engineering practices. We use automated testing, monitoring, and version control to ensure integrations remain stable and reliable over time.
We work across a range of government technologies including case management systems, document management systems, identity platforms, payments services, CRM, ERP, data warehouses, and cloud services. For each project, we ensure alignment with government standards such as the Technology Code of Practice, Government Service Standard, and relevant departmental architectural guidelines.
Before go-live, we conduct end-to-end testing covering performance, security, data quality, and operational viability. We support rollout, monitoring setup, and handover to operational teams. Post-launch, we provide ongoing optimisation, updates, and incident response as part of our managed service offering.

Readiness checklist for Interoperability and Integration
- Define the systems, processes, and teams involved in the integration and the outcomes you want to achieve.
- Document existing data flows, APIs, interfaces, and known architectural constraints.
- Confirm governance and compliance requirements, including data protection, audit, and security obligations.
- Identify preferred standards or patterns to be used (e.g., REST APIs, messaging queues, event streams, SFTP, cloud integration).
- Prepare details of hosting environments, legacy platforms, and vendor dependencies that may influence integration design.
- Determine whether you require additional services such as API strategy, data architecture, cloud migration, or ongoing managed support.
