Capabilities / Systems Integration
Systems Integration
Systems integration is YAVA making separate technologies, including software, IT, operational technology and equipment, behave as one accountable system. We connect legacy and modern systems through a governed integration layer, then test, commission and support the result.
Problems we are brought in for
Where this work matters.
Point-to-point sprawl
Systems wired directly to each other over years, until no one can change one without breaking another.
Systems that do not agree
Separate systems holding different versions of the same truth, so reports and operations diverge.
Unclear accountability
Multiple vendors for software, hardware, networks and field work, and no one accountable when the whole fails.
Services
What sits under systems integration.
Each service below is delivered on its own or combined with others. Making separate technologies, old and new, behave as one accountable system.
Application integration
Connecting applications so a process runs end to end, with data moving reliably between them.
API integration
Designing and connecting APIs across internal and third-party systems, with versioning, security and monitoring.
Data integration
Bringing data together from multiple systems into a consistent, usable form for operations and reporting.
Middleware
Messaging, queuing and middleware that let systems communicate dependably, including under load.
Cloud and on-premises integration
Integrating cloud services with on-premises and field systems into one coherent estate.
Legacy system integration
Connecting older systems that cannot be replaced yet, so they work with modern software and data.
IT and OT integration
Connecting information technology with operational technology across a monitored boundary, so the two work together without exposing either.
Security systems integration
Integrating CCTV, access control, alarms and sensors into a single, coherent security picture.
Command and control systems
Bringing data and systems together into a command environment operators can actually run an operation from.
Testing, commissioning and assurance
Testing, commissioning and assuring integrated systems so they work as one at handover, not just in parts.
How we deliver
Delivery.
We design the integration, build it through APIs, middleware and data pipelines, and prove it works end to end before handover. One team is accountable for the integrated system, not just its parts.
How it connects
Integration.
Integration is the capability. We connect cloud and on-premises, IT and OT, and old and new, with security and monitoring designed into the boundary.
YAVA advises, builds, integrates, deploys and supports. This capability is one part of a single lifecycle, not a standalone product.
Where we apply it
Relevant sectors.
Applicable experience
Evidence.
Representative work relevant to this capability. Some engagements are anonymised by client where confidentiality requires it.
YAVA does not publish invented clients, projects or results. Where a client is not named, the engagement is described by sector, region and year, with accurate technical detail.
FAQ
Common questions.
Can you integrate systems you did not build?
Yes. Most integration work involves systems built by others, including legacy systems that cannot be replaced yet.
How do you handle IT and OT together?
We connect them across a monitored boundary, so operational technology is integrated without being exposed to unnecessary risk.
What do we receive at handover?
An integrated system that has been tested and commissioned as a whole, with documentation and support, not a set of parts that work individually.
Can YAVA work in remote or low-connectivity environments?
Yes. Much of our work is at remote and high-risk sites. We design for intermittent connectivity and can deploy field engineers where support on the ground is limited.
Who is accountable once the system is live?
The same team that advises and builds also supports the system in operation, so there is a single line of accountability to the client rather than a hand-off between firms.
How is a piece of work scoped and priced?
Each engagement is scoped and priced on its own terms, with the deliverables, service levels and assumptions agreed and written down before work begins.
Can you work alongside our existing suppliers?
Yes. We routinely deliver inside existing frameworks and alongside incumbent suppliers, including on systems built by others.
