## 2. Problem Space
- Critical business operations remain trapped in Excel Budget Workbooks, Disconnected HCM Exports & Legacy Finance Sheets, creating audit risk, manual reconciliation overhead, and rising support costs.
- Duplicate queries, cloned reports, and undocumented triggers make impact analysis slow and expensive across hcm salary & position control lines.
- Lack of automated binary-to-database metadata mapping causes traditional consulting shops to pad estimates with 40% manual discovery buffers.
- Leadership needs a predictable, fixed-fee phased timeline with verifiable test specifications and zero-downtime cutover guarantees.

## 3. Technical Solution Architecture
- Automated Phase 0 AST & binary scan mapping Excel Budget Workbooks, Disconnected HCM Exports & Legacy Finance Sheets artifacts directly to live Oracle dictionary metadata and profiling production data.
- Target architecture built on Oracle APEX 24.2 Budget Operating System (BOS) + Autonomous DB + AOP Budget Books, consolidating cloned queries into governed core SQL views with runtime Smart Filters.
- Automated generation of full Business Requirements Documents (BRD), Technical Approach Docs, Testing Specifications, and Verified Test Results.
- Zero-trust SSO/MFA (Entra ID / Okta) paired with database-enforced row-level security (VPD / RAS) and SQLcl Liquibase CI/CD pipelines.

## 8. Principal Architect FAQ
### Q: What are the primary levers that control the cost of Public Sector Budget Operating System (APEX)?
A: Cost is controlled by five levers: (1) collapsing cloned query fan-out across hcm salary & position control lines into canonical core SQL views, (2) percentage of business logic already in database packages vs. UI triggers, (3) production data quality profiled during Phase 0, (4) external integration/SSO count, and (5) cutover downtime requirements.

### Q: How does your tool convert binaries (.fmb, .rdf, etc.), map database metadata, and generate documentation?
A: Our automated analyzer parses legacy binaries and source files, extracts every trigger, query, and UI control, cross-references them against live database dictionary metadata (ALL_TAB_COLUMNS, ALL_DEPENDENCIES), profiles actual column data distributions, and automatically generates the Business Requirements Document (BRD), Technical Approach Doc, Test Specifications, and Verified Test Results.

### Q: What does a typical project timeline look like from kickoff to production cutover?
A: Projects follow four gated phases: Phase 0 (Weeks 1-2: Binary AST Scan, Data Profiling & Auto-Generated BRD), Phase 1 (Weeks 3-6: Core Schema Uplift & Working Pilot), Phase 2 (Weeks 7-12: Automated Conversion Sprints & Test Spec Execution), and Phase 3 (Weeks 13-16: Parallel Run, Zero-Downtime Cutover & 30-Day Hypercare).
