EXL reduces architecture review times from 5 days to 15 minutes with Eraser

About EXL

EXL is a global data analytics and digital operations leader that helps Fortune 500 enterprises modernize through AI-first digital transformation. Since 1999, EXL has delivered high-impact solutions across insurance, banking, and healthcare for a global clientele.

The Challenge

Manual governance and static architecture diagrams couldn’t keep up with EXL’s agentic AI framework

At EXL, the Enterprise AI team develops and operationalizes the agentic AI systems that power the company’s global operations. For this team, rigorous technical documentation is essential to keeping complex IT environments secure, auditable, and aligned with enterprise governance standards.

But, as EXL shifted toward an AI-first operating model, manual documentation workflows and static architecture diagrams could no longer keep pace with growing system complexity and scale. These gaps created bottlenecks inside SARA, a critical internal platform for security architecture reviews.

Manual review cycles stalled the solution development lifecycle

To automate security architecture reviews, EXL developed SARA, an AI-powered platform that validates designs against enterprise policies. While SARA handled ingestion, analysis, and policy checks, finalizing reviews still relied on direct involvement from the Information Security Group.

When architects submitted designs, security experts manually verified the findings – a process that could stall the software development lifecycle for up to five business days. And without a way to programmatically render corrected designs, even minor policy updates triggered tedious manual redrawing. This workflow limited the team’s capacity to roughly 100 architecture reviews per year.

Ad-hoc solutions left architects with unsustainable manual workloads

The Enterprise AI team initially tried to close these gaps with open-source diagramming tools and manual drafting. But these solutions offered limited control and still produced cluttered visuals that stalled executive-level approvals.

Plus, manually redrawing diagrams for every policy or design change created unsustainable workloads. Staying with the status quo meant sacrificing speed, burning valuable engineering time on diagramming work, and potentially compromising the governance standards required in regulated industries.

For their AI agents to be truly effective, the team knew they had to decouple the visual layer from manual effort. They needed a scalable, code-aware engine that could automatically translate complex, structured logic into interactive, presentation-grade diagrams. This search led them to Eraser.

“Security architecture reviews took up to a week to complete because they depended heavily on manual work and expert availability. We knew that if we could automate validation and visualization, we’d avoid human error and save a significant amount of time and effort.”

The Solution

Eraser turns EXL’s internal intelligence into presentation-grade documentation

EXL’s adoption of Eraser began with a fast, low-friction rollout. The platform’s intuitive, developer-centric environment helped the Enterprise AI team ramp up quickly without complex onboarding.

“The process was straightforward and highly efficient,” the team shares. “We found the platform’s documentation and support to be excellent, which enabled us to drive value from day one.”

Those early wins set the foundation for deeper integration into SARA.

Automated architecture remediation that keeps pace with policies

EXL integrated Eraser’s diagram-as-code capabilities into SARA to eliminate the friction between security policy validation and visual redesign. As SARA ingests architecture diagrams, analyzes them against enterprise security policies, and proposes remediations, it uses Eraser’s API to programmatically redraw the corrected architecture.

“Integrating Eraser into our security workflow changed the nature of the job,” shares an AI Architect at EXL. “We no longer spend time manually sketching boxes and arrows. We focus on the security logic and policies while Eraser handles the visualization.”

By automating this last mile, EXL has compressed the security review process from days to minutes. This transformation empowers architects to produce clean, audit-ready documentation through a fully automated workflow.

Standardized visual clarity for enterprise-grade governance

Beyond internal speed, Eraser gives EXL a consistent visual standard the team can apply across security architecture and leadership reporting. Even in heavily regulated sectors like insurance and banking, diagrams are accurate, sharp, and standardized, supporting fast technical audits and executive sign-offs.

Eraser’s well-defined integration model ensures that every diagram reflects EXL’s preferred structure and style, producing clutter-free visuals that are easy to interpret at a glance. This consistency strengthens governance, builds stakeholder trust, and ensures every design meets EXL’s internal “gold standard” for professional documentation.

“Eraser gives us the quality and structure we were looking for. It transforms our internal data into clean, standardized architecture diagrams that are ready for audits, governance, and meaningful stakeholder collaboration.”

The Result

EXL builds a scalable governance engine and ensures audit-ready transparency

With Eraser, EXL has turned architecture governance into a scalable, AI-driven capability instead of a manual bottleneck. Now, review capacity, documentation quality, and compliance advance alongside EXL’s AI initiatives.

By reducing architecture review time to as little as 15 minutes, EXL has significantly increased its annual review capacity. The team has already reached its initial scaling goal of 500 reviews per year, while maintaining the visual polish and technical rigor that stakeholders expect.

Moving forward, EXL is expanding Eraser’s footprint into the broader product development lifecycle. The team is exploring new ways to automate architectural designs from scratch, helping EXL move toward an AI-first documentation standard. In this model, complex visuals will automatically update with every system change across EXL’s workforce.

“Eraser has been a true driver of operational excellence. It allows our architects to spend less time on manual diagramming and more time focusing on high-value technical design and strategic innovation.”
