AI-Powered Legacy Application Gap Assessment
How Sembix assessed thousands of features in days — not months — to give a regional organization its first complete modernization picture
Regional Public Sector Organization
A large regional public sector organization providing shared technology platforms and operational services to hundreds of member organizations across a major metropolitan area. The organization supports critical workforce management, professional development, and administrative operations serving hundreds of thousands of end users. Their flagship platform — a comprehensive event management and workforce coordination system — is a mission-critical application relied upon by organizations across the state.
Stalled Modernization with No Visibility into Completion Status
The organization had invested years in modernizing their flagship legacy application into a next-generation platform, but the original development team was no longer engaged. Leadership needed answers to fundamental questions: How complete was the modernization? What code was usable? What work remained?
A traditional manual assessment of thousands of features would take months and still leave gaps in understanding.
- Scale: thousands of features across dozens of functional areas requiring individual assessment
- Stalled Development: Multi-year NextGen platform development had stalled with unknown completion status
- Knowledge Loss: Original development team departed with no assessment documentation
- No Documentation: No record of which features had been completed, partially built, or never started
Sembix deployed Sembix Strata™ in a secure AWS environment to perform AI-powered semantic gap analysis between the legacy and NextGen systems, delivering comprehensive functional parity assessment with interactive executive-ready reports.
AI-Powered Feature Comparison
Strata automatically compared legacy and NextGen features using multi-dimensional semantic analysis across acceptance criteria, requirements, business rules, and workflows.
Functional Area Categorization
AI grouped thousands of features into dozens of logical functional areas, identifying patterns and relationships that manual analysis would miss.
Quantified Gap Assessment
Generated precise match scores for every feature, classifying each as full match, partial match, or missing — with confidence scoring.
Executive-Ready Reporting
Produced interactive HTML dashboards and professional PDF reports with visualizations, enabling data-driven modernization decisions.
AWS Services Utilized
Complete Functional Parity Assessment
First-ever complete picture of modernization status across all features
Every feature assessed with AI-powered semantic comparison
AI-categorized with aggregate metrics per area
Acceptance criteria, requirements, business rules, workflow, and data model
AI-Powered Semantic Analysis
Used Amazon Bedrock for multi-dimensional feature comparison across multiple scoring dimensions including acceptance criteria, requirements, business rules, workflow alignment, and data model analysis.
Functional Area Intelligence
AI categorized all features into logical functional areas with aggregate metrics per area, surfacing critical gaps that would have been missed in a manual review.
Executive Decision Support
Interactive HTML dashboards with scatter plots, classification charts, heatmaps, and sortable tables delivered to executive leadership for budget and roadmap decisions.
Actionable Modernization Roadmap
Prioritized gap analysis enabled the organization to make informed build-vs-buy decisions, with clear visibility into remaining development effort by functional area.
Reusable Assessment Methodology
The AI-powered assessment approach is now a repeatable pattern — automated backlog comparison, semantic analysis, and executive reporting — applicable to any legacy-to-modern migration.
