AI Case Studies in Practice: Delivery Based on an AI-Assisted Specification

No items found.

In real projects, engineering problems rarely come in a clean or predictable form. They appear late, affect multiple systems and often put delivery under pressure. AI can help in these situations, but not on its own.

Business Context

A long-developed internal testing platform used across FE and BI teams needed new features. The extension became a critical-path dependency in a two-year program, so timeline compression was mandatory.

Situation

Original implementation estimate was three weeks, but delivery had to be reduced to one week. The final handover to integration testing happened in six days, while coding plus factory tests took less than three days.

Why it was hard

Legacy codebase with approximately seven years of continuous evolution
Strict requirement to match a pre-approved markdown specification
High trust and reliability expectations from the client

How we used AI

The functional specification itself was prepared with AI support and approved by the client
Scope was decomposed into smaller implementation units
Each unit was implemented with AI assistance and then reviewed by developers
AI-generated tests were included in the verification scope
A local model was used instead of public cloud models due to client trust requirements

Outcome

Compressed timeline achieved
Core development and factory testing completed in under three days
Successful production deployment and ongoing productive use

Delivery Impact - What this means for software delivery

AI-assisted specification and implementation enabled substantial schedule compression on a critical-path item. The key benefit was not only faster coding, but also faster convergence between requirements, implementation, and validation.

What made the difference

Upfront AI-assisted specification
Task decomposition
Developer-led quality control
Validation of AI-generated tests
Appropriate model choice for security and trust constraints

AI increased execution speed, while delivery reliability was maintained through expert review and disciplined verification.

AI Adoption Is a Business Transformation. It Starts Where Deployment Ends

The real challenge of enterprise AI starts after the technology works. The next step is turning individual gains into a new operating model, with different ownership, processes, management practices and governance. Roman Marek, AI Architect at Trask, explains what separates experimentation from real adoption, and why the ultimate test is whether the organization starts working differently.

Faster Code, Slower Fixes: 3 Security Gaps AI Is Exposing

AI is changing both sides of software security. It helps adversaries find vulnerabilities faster, but it can also shorten the path from finding a problem to fixing it. It also exposes another issue: many companies can already find security problems. The harder part is deciding which ones matter, fixing them fast enough and getting those fixes safely into production without slowing down the business.

Case Study: From 16 hours to 30 Minutes – Trask AI Agent Helps Speed Up MONETA Bank's Payment Card Disputes

Modern banks face increasing pressure to resolve payment card disputes quickly, accurately, and in full compliance with Payment Services Directive 2 (PSD2). MONETA Bank, a leading CEE bank (formerly GE Money Bank), can now automate most of this process with an agentic AI solution co-developed with Trask – reducing handling time from ~16 hours to ~30 minutes.
