Assurance Optimisation and Automation
Moving security, accessibility and performance assurance earlier, then automating repeatable controls within the delivery pipeline.
- Delivery optimisation
- CI/CD assurance
- Controlled automation
Context
The transformation environment
Release Assurance across Civil, Family and Tribunals services included security, accessibility and performance sign-offs. These controls were essential, but their late position in the workflow created an assurance gate of approximately eight weeks and delayed feedback until Operations, Training and Adoption teams had already invested heavily in release candidates.
The challenge
What had to be resolved
Security, accessibility and performance assurance occurred too late to guide engineering decisions economically.
The eight-week assurance constraint was produced by the combined release-assurance pathway, not by security assurance alone.
Manual scans and hand-offs consumed scarce specialist capacity and made release confidence dependent on late-stage activity.
Any redesign had to preserve assurance quality, evidence and human oversight while improving delivery flow.
The response
How Tawose Group addressed the challenge
- 01
Prove the earlier-assurance model
Worked with assurance team leads and technical leads to run a focused proof of concept, demonstrating that assurance activity and evidence could be moved earlier without weakening control.
- 02
Institutionalise assurance earlier
Extended the proven approach across security, accessibility and performance assurance, embedding earlier engagement and evidence creation within the delivery workflow.
- 03
Automate repeatable controls
Ran further proofs of concept and integrated enterprise-grade SAST and DAST capability, Pa11y accessibility scanning, and industry-grade load and stress testing into CI/CD pipelines.
- 04
Retain expert judgement
Kept specialist engineers focused on complex user behaviours, scan analysis, profile refinement, infrastructure tuning, exceptions and confirmation that release KPIs had been met.
Value created
What changed
Automated approximately 80% of repeatable security-assurance scans within pre-live pipeline activity.
Achieved close to 100% automated accessibility scanning through Pa11y integration.
Automated approximately 85% of performance-assurance execution, retaining manual intervention for the complex 15% requiring expert analysis.
Moved assurance evidence earlier, reduced avoidable manual effort and created faster feedback without removing human oversight.
Leadership approach
Governance with direct intervention
Our consultant - Tayo, treated assurance as a delivery-system problem rather than a control to bypass. The change was achieved by leading assurance leads and technical leads through evidence-led proofs of concept, proportionate governance and controlled adoption, first changing where assurance happened and then changing how repeatable work was executed.
