The Challenge

Why Traditional Development Falls Short

Code-centric development leads to maintenance problems, hinders modernization, and causes business misalignment

The Problem

Traditional development is code-centric. Requirements get outdated, documentation drifts, and when bugs appear, we dig through code to understand what the system was supposed to do.

AI coding tools make this worse by generating code faster without fixing the underlying process problems.

The Determinism Myth: Some believe AI code generation only works with extensive specifications that force deterministic output. This misses the point entirely.

The Solution

AI Unified Process flips this around. Requirements stay at the center, and everything else gets generated from them using AI as the consistency engine.

Iterative Improvement: Through short iterations, specifications, code, and tests improve together. Documentation enables sustainable development and modernization.

Test-Driven Consistency: Tests ensure the system behaves the same regardless of code generation changes, enabling safe refactoring and evolution.

How It Works

Four Agile Phases

Each phase runs multiple short iterations where all disciplines work together, not in sequence. All phases run in iterations throughout the project lifecycle.

Requirements → AI Generation → Business Review → Repeat

Inception

  • Business Requirements Catalog
  • Initial stakeholder alignment
  • Test strategy planning
  • Quick iterations and feedback

Elaboration

  • Business Use Case Diagrams
  • Entity Models
  • System Use Case Diagrams with business validation
  • Test case development

Construction

  • Detailed System Use Case Specifications
  • AI-generated application code
  • Unit testing, integration testing
  • Developer review and iteration

Transition

  • User acceptance testing
  • Continous delivery and stakeholder feedback integration
  • Production optimization
  • Continuous improvement

Core Principles

Six Fundamental Principles

Principles that ensure success in agile, iterative development

  • Requirements-Driven: Specifications drive everything else, not code
  • AI-Assisted: AI handles tedious work, humans focus on business logic
  • Iterative Improvement: Specs, code, and tests evolve together through short cycles
  • Test-Protected: Comprehensive tests ensure consistent behavior during AI regeneration
  • Stakeholder-Centric: Continuous validation with business users
  • Traceable: Every line of code traces back to business requirements
Beyond Determinism

Why Perfect Specifications Miss the Point

Addressing the determinism debate: It's not about perfect specs, it's about iterative improvement

The Determinism Fallacy

Critics argue AI code generation only works with exhaustive specifications that force deterministic output. This assumes we need perfect requirements upfront.

Reality: Perfect specifications are impossible and unnecessary. The real value comes from iterative improvement.

Our Iterative Approach

Through short cycles, specifications become clearer, AI generation improves, and tests get stronger. Each iteration builds on the previous one.

Key insight: Tests ensure consistent behavior regardless of how the AI generates code. This enables safe evolution and modernization.

How Iterative Improvement Works

  • Start Small: Begin with basic requirements and generate initial code
  • Test Everything: Create comprehensive tests that capture expected behavior
  • Refine Continuously: Improve specs based on stakeholder feedback
  • Regenerate Safely: Tests protect against regression during AI code updates
  • Document Reality: Keep specifications aligned with what actually works
