For many federal agencies, modernization begins with a simple but difficult question: What do we actually have? Years of incremental updates, policy-driven adjustments, and mission-critical patches often leave behind an ecosystem that “works,” but is poorly documented and inconsistently understood.

Such situations make modernization riskier than it needs to be, because without understanding the entire ecosystem, inadvertent breaks from changes become much more likely. 

This was the challenge facing a federal agency whose compliance and identity management platform handled access requests for more than 40 financial and administrative systems. The mission was essential, but the underlying architecture had grown dense and opaque.

To move forward confidently, the agency needed clarity—true visibility into how its isolated systems operated, how data flowed and where hidden dependencies lurked. CGI Federal delivered that clarity through a rapid, full platform analysis that turned years of technical complexity into a transparent, actionable, modernization-ready knowledge base.

In a matter of hours, we analyzed all six platform components (Website, Database, Batch, Reporting, and multiple Corollary scripts) and transformed them into a single, searchable source of truth. What had once existed as scattered code, tribal knowledge and fragmented documentation became a coherent picture of the system’s architecture, relationships and workflows.

This provided the foundation for safe transformation.

Solution

  • Full platform code and artifact analysis: A comprehensive examination across all six components captured system behavior, integration logic and architecture with 100% coverage—ensuring no hidden or undocumented logic was left unexamined.
  • Entity and relationship mapping: By extracting and validating 4,748 entities and 5,856 relationships, we were able to articulate the system’s true data structure and identify its most critical dependencies.
  • Architecture and integration discovery: Complete end-to-end workflow mapping illuminated how access requests traversed more than 40 financial and administrative systems—revealing where processes were efficient, fragile, redundant or ripe for automation.
  • Unified documentation suite: Finally, we consolidated findings into a searchable, cross-linked knowledge base that clarifies onboarding, governance, risk mitigation, and modernization planning.

Outcomes

100% component coverage: a foundation for trust

Achieving complete analysis coverage meant the agency could move forward without guesswork. Every component, script, query and workflow was accounted for. This is crucial during modernization: when agencies lack full visibility, changes in one system can unintentionally ripple across others. By eliminating unknowns, we helped the organization reduce risk before modernization even began.

A system documented at scale: turning complexity into capability

Analyzing 2,017 files and thousands of relationships produced insight rather than simple documentation. Understanding how the system actually behaves, rather than how it was intended to behave, equips teams to make informed decisions about what to update next, what to retire and what to redesign. This baseline becomes a living asset that strengthens technical governance and accelerates every future change.

Accelerated impact analysis: modernization without the blind spots

With a clear dependency and dataflow map, the agency can now evaluate proposed changes in minutes instead of days. This minimizes disruptions, dramatically reduces the risk of breaking downstream processes, and shortens the time needed to evaluate system upgrades or policy-driven adjustments. For a platform supporting more than 40 interconnected systems, this speed and precision fundamentally change how fast the agency can evolve.

A modernization-ready ecosystem: clarity that moves the mission forward

The consolidated knowledge base transforms how teams onboard, collaborate and plan. New developers are more productive and faster. Governance boards have the information they need to make confident decisions. Modernization teams can design future architecture grounded in a concrete understanding rather than in isolated silos.   This helps position the agency to scale technology in a more coordinated, cost-effective and sustainable way. 

CGI is bringing AI-enabled modernization to the federal mission

This effort reflects CGI’s broader commitment to helping federal agencies modernize with confidence using AI-powered tools, automation, and deep mission understanding. Our AI-driven analysis accelerates discovery, reduces risk, and provides the technical clarity agencies need to transform at scale. From code analysis to data integration to enterprise modernization, CGI combines decades of federal experience with cutting-edge AI capabilities to help agencies strengthen security, elevate performance, and deliver on their mission faster. With CGI, modernization doesn’t just move forward—it moves forward with intelligence, precision and purpose.
