2.5X FASTER DELIVERY FOR A LEADING RETAIL BANK

Agentic development reduced backend development from 10 to 4 days, achieving 60% faster development and an overall 2.5x acceleration.

INTRODUCTION

Large backlogs become harder to deliver when aggressive deadlines are combined with external dependencies and fragmented processes.

A leading retail bank needed to complete 46 backend stories across 10 epics within a demanding timeline. Delivery also depended on multiple external teams and a highly bureaucratic process.


CI&T introduced an agentic development workflow to accelerate downstream execution. Powered by CI&T Flow, AI supported code generation, testing, and implementation while human validation remained part of the process.


The initiative made development 60% faster, reducing the cycle from 10 to 4 days and contributing to an overall 2.5x acceleration.

THE CHALLENGE: DELIVERING A LARGE BACKLOG FAST

A 46-story backend backlog had to be delivered within an aggressive timeline despite external dependencies and fragmented processes.

Large Backend Backlog

The team needed to deliver 46 stories across 10 epics within a compressed delivery schedule.

External Dependencies

Multiple dependencies outside the squad increased coordination needs and made delivery more difficult to predict.

Fragmented Process

A bureaucratic delivery process and limited agentic AI maturity created additional friction throughout development.

THE SOLUTION

CI&T implemented an agentic development workflow that combined human-defined requirements
with AI-supported code generation, testing, and validation.

Ready Requirements

People defined requirements and provided specific inputs before AI-assisted development began.

Agentic Development

A specialized development agent generated code and tests, reducing repetitive engineering work and accelerating implementation.

Human Validation

Human-in-the-loop checkpoints ensured engineers remained responsible for validating AI-generated implementation throughout the process.

THE IMPACT

The agentic workflow accelerated backend development despite external dependencies and process constraints.

FASTER DEVELOPMENT

Development became 2.5x faster

Cycle time reduced by 60%, from 10 to 4 days

AI supported code generation, testing, and code review


TEAM READINESS

AI engineering roles

TECHNOLOGIES USED

CI&T FLOW

CI&T Flow supported AI-assisted development workflows, helping teams connect requirements, implementation, testing, and human validation.

DEV AGENT

A specialized development agent generated code and tests from structured requirements while maintaining human validation throughout execution.

HUMAN VALIDATION

Human review checkpoints helped teams verify AI-generated work and maintain engineering oversight throughout development.
