Oct 1, 2025

October 2025 performance summary for the developer team, focusing on delivering business value through feature delivery, bug fixes, and cross-repo improvements across the Approved Premises UI, API, and Temporary Accommodation UI. The month saw substantial UI improvements to placement workflows, enhanced UI rendering for form controls, data quality enhancements, and migrations towards modernized service layers, all while stabilizing CI/CD pipelines and test infrastructure. Key features delivered and enhancements by repo: - ministryofjustice/hmpps-approved-premises-ui - Placement Submission and Flow Enhancements: introduced new submission handling for placements, an updated update-criteria layout, a placement flow selector, and rendering of all placements linked to a request with the current premises name displayed when applicable. - UI Rendering Improvements: rendered radios and checkboxes vertically and fixed rendering of confirmation reason text blocks for clearer user guidance. - UI/UX refinements and data flow: expanded placement UI with expandable cards, improved placement summary content and links, and status tagging improvements to support clearer status visibility. - ministryofjustice/hmpps-temporary-accommodation-ui - Migrate to v2 services and remove legacy v2 references: consolidated Premises and Bedspace service usage on v2 to simplify architecture and reduce maintenance surface. - Test infrastructure improvements and reliability: strengthened end-to-end/integration test frameworks and CI configurations for stability and clearer diagnostics. - Data model improvements and test utilities: standardized turnaround day fields and improved premises data factory mappings for consistent testing. - ministryofjustice/hmpps-approved-premises-api - CI/CD Pipeline Reliability Improvements: addressed concurrency and test splitting in CI, reducing pipeline cancellations on main and stabilizing test execution. Major bugs fixed: - Do not show 'unable to book' for new placements: corrected UI logic to avoid misleading availability messaging for new placements. - Remove rogue debug: cleaned runtime output by removing stray debug statements. - Only show placements that can be changed: ensured UI lists only changeable placements, reducing confusion and errors. - Remove past date validation: adjusted validation to avoid blocking valid future scheduling while maintaining data integrity. - Data consistency and merge fixes: resolved merge issues and introduced separate keys for new placement dates to ensure accurate data handling. - Tests and navigation fixes: stabilized summary list matcher, corrected back links from placement requests, and fixed related assertion errors in integration tests. Overall impact and accomplishments: - Improved user experience and clarity in placement workflows, reducing friction in placement submissions and changes. - Strengthened data integrity, code quality, and maintainability through linting, de-duplication, and refactoring. - Reduced maintenance surface and technical debt by removing unused endpoints and legacy references, and consolidating services to modern stacks. - Increased reliability and velocity through improved test infrastructure and CI/CD stability, enabling faster and safer releases. - Cross-team collaboration improvements with clearer ownership signals and better test diagnostics enabling more predictable deployments. Technologies and skills demonstrated: - Frontend: React/TypeScript, UI/UX design improvements, accessible form rendering, and dynamic placement views. - Testing: Cypress E2E tests, integration tests, and robust test infrastructure improvements for stability and diagnostics. - Backend/DevOps: CI/CD pipeline hardening, test splitting optimizations, API surface cleanup, and data model improvements. - Data engineering: standardization of turnaround fields and improved data factories for reliable test data.
