Clara/EA

Cases

The framework applied — by people and by AI agents

Two series of cases. In the first, an AI agent receives Clara/EA as its method and an organization's public disclosure as its only input — and returns the business architecture instantiated, with traceability back to the source. In the second, applications of the framework led by the author in real projects, over decades.

Market Cases · Agentic AI

The framework as instruction for AI agents

Because it is universal, recursive and explicit about what each layer contains, Clara/EA works as a specification that AI agents can operate. In this series, an agent receives the method as its instruction and an organization's public disclosure as its only input — and returns the business architecture instantiated, domain by domain, with traceability back to the source.

Financial Conglomerate · Public Disclosure · Layers 0–VIII

Itaú Unibanco through the Clara/EA method

Mapping of the eight business-architecture layers of Itaú Unibanco Holding S.A., plus the strategic drivers, built exclusively from the Form 20-F, Reference Form, Pillar 3, Management Discussion & Analysis and IR portals. Each domain lists the sources that support it; entities in transition or discontinued carry a status marker.

Financial and Insurance Conglomerate · Public Disclosure · Layers 0–VIII

Bradesco through the Clara/EA method

Mapping of the eight business-architecture layers of the Bradesco Organization, plus the strategic drivers — a conglomerate in which the insurance business accounts for about 41% of profit and whose transformation plan explains the movement visible across every layer. Built from the Form 20-F, economic and financial analysis reports, Pillar 3, Integrated Report, corporate organization chart and the healthcare reorganization filings.

Investment Platform · Public Disclosure · Layers 0–VIII

XP Inc. through the Clara/EA method

Mapping of the eight business-architecture layers of the XP Inc. group, plus the strategic drivers — a Cayman holding listed on Nasdaq whose main channel sits outside the company: around 600 independent advisory offices, under a rule that changed in 2023. Built from the Form 20-F and exhibits, earnings releases, Pillar 3, Schedule 13D, the compliance portal and CVM rules.

Digital Bank · Public Disclosure · Layers 0–VIII

Nubank through the Clara/EA method

Mapping of the eight business-architecture layers of the Nu Holdings conglomerate, plus the strategic drivers — 139 million customers, a prudential conglomerate led by a payment institution, and a channel layer with a single element: the app. Built from the Form 20-F and exhibits, quarterly releases and financial statements, Pillar 3, CNBV, SFC and OCC authorizations and BACEN/CMN rules.

Travel & Tourism · Public Disclosure · Layers 0–VIII

CVC Corp through the Clara/EA method

The first case outside the financial sector. Mapping of the eight business-architecture layers of CVC Corp, plus the strategic drivers — a network in which 1,620 of 1,627 stores are franchises with no fee and no royalties, regulated by the tourism authority rather than the central bank. Built from the Reference Form, earnings releases, financial statements, the shareholders' agreement, corporate policies and the Sustainability Report.

Use Cases · Led by the author

Applications in complex environments

Clara/EA was born and matured in large-scale projects — traditional financial institutions, new market entrants, multinational retail, greenfields, insurers, and data/analytics organizations. Each case below addresses a distinct class of architectural problem.

Financial Institution · Traditional

The origin of the framework: aligning technology to strategy in times of digital transformation

A high-complexity banking environment with multiple strategic and transformational projects running in parallel. The continuous need to adapt the technology architecture to shifting strategy revealed the limits of traditional Enterprise Architecture practices — particularly in how shallowly they treated business architecture. The first insights that would shape Clara/EA were born here: the recognition that the framework had to address the business with the same methodological rigor reserved for technology.

Financial Industry · Open Finance & APIs

Open, API-driven architecture facing new market entrants

Competitive pressure from fintechs and regulatory demands of Open Finance reshaped the architecture of products and services. Clara/EA was applied to map how products would become invocable both internally and externally under an API-first layer — preserving coherence of customer experience (UX/UI) and integrating with the Open Finance ecosystem.

International Retail · Post-M&A

Portfolio modernization and rationalization in a post-merger multinational

International retail company formed through successive mergers and acquisitions. The result was a complex, redundant, operationally expensive environment. Clara/EA was applied to map overlapping capabilities across brands and geographies, rationalize the application portfolio, and design a modernization roadmap with objective consolidation criteria.

Greenfield · New Financial Institution

Architecture as a foundation pillar to scale from zero

Building a financial institution from a blank page. Unlike the defensive use of the framework — mapping what already exists — here Clara/EA served as architectural blueprint for organic growth. The 13 layers, hierarchies, and relationships were defined from day one, enabling accelerated expansion without architectural debt accumulating in the early years.

Insurance · Strategic Planning

Business mapping and three-year transformation roadmap

Support to the strategic planning of an insurance company. Clara/EA applied as a diagnostic instrument: mapping the business across its eight layers (from Market to Metrics), identifying structural gaps and debt, and translating the result into a three-year roadmap of initiatives — prioritized by their contribution to each layer and impact on the business.

Data & Analytics Intelligence

Building the strategy itself in a data and analytics organization

Application in an organization whose value proposition is data and analytical intelligence. Clara/EA was used to build the strategy itself — applying the upper layers of the pyramid (Market, Brand, Channels, Products) to map the analytical offering, articulate competitive positioning, and design a coherent portfolio of data products before descending to the technology architecture that supports it.
