Framework for AI-Assisted Software Engineering

A modern software engineering methodology where AI is embedded into every stage of the lifecycle to increase efficiency, improve quality, and accelerate time-to-market.

Version 1.0

Introduction

FASE outlines a modern software engineering methodology where AI is embedded into every stage of the lifecycle to increase efficiency, improve quality, and accelerate time-to-market.

The framework empowers software designers, developers, and testers to achieve more in less time with higher consistency and quality. Its core principle is that human engineers focus on the "what" while AI handles much of the "how".

FASE extends well beyond code generation. It provides structured guidance across all key software engineering disciplines, including design, development, testing, and deployment. For each discipline, the framework defines recommended practices, tools, and measurable outcomes.

FASE is intentionally designed as a flexible framework rather than a rigid set of steps. Implementers are encouraged to create their own detailed implementation guides tailored to their specific organizational context.

Foundation Principles

The core principles that guide AI-Assisted software engineering excellence

Documentation as a First-class Citizen

Documentation is treated with the same importance as code, design, and testing. Well-structured and continuously updated documentation forms the foundation for effective AI-assisted development, enabling accurate code generation, better decision-making, and faster onboarding. By prioritizing documentation from the start, teams reduce ambiguity and ensure long-term maintainability.

Human Ownership and Accountability

AI can accelerate development, but responsibility always stays with humans. Engineers and product teams must validate, review, and approve every AI-generated artefact to ensure correctness, safety, and alignment with requirements. AI assists the process, but humans remain accountable for the final outcome and its real-world impact.

Quality In, Quality Out (QIQO)

AI output is only as good as the input provided. Clear specifications, well-defined patterns, consistent guidelines, and accurate context lead to higher-quality AI-generated code, tests, and documentation. Investing in strong inputs through better prompts, better standards, and better context, directly improves the reliability and usefulness of AI outputs.

Human-in-the-Loop (HITL)

AI accelerates creation, but refinement and approval belong to humans. Across all phases of the lifecycle, from requirements to testing, humans validate AI outputs, refine them, and ensure they meet expectations. This collaborative loop ensures that speed does not compromise quality, and that the final product reflects both automation efficiency and human judgment.

Measurable Improvement

AI adoption must result in tangible and trackable improvements. Teams should measure key metrics such as development speed, coverage, defect reduction, rework levels, and overall quality. By continuously monitoring outcomes and comparing them to historical baselines, organizations can validate the value of AI-assisted development and refine their approach to maximize impact.

Start with Meetings

Meetings, workshops, and brainstorming sessions are where ideas are born. Recording these interactions creates a rich source of information that can be used to build accurate specifications.

Practices
  • 1. Record your meetings (online or in person) with transcript generation
  • 2. Use AI to generate notes, summaries, and action items from transcripts
  • 3. Apply AI to analyze meeting effectiveness and participation
  • 4. Close feedback loops by tracking unresolved questions and blockers
Tools

Create Specifications

AI tools can be extremely helpful in generating software specifications including BRS, SRS, design specifications, mind maps, and architecture diagrams.

Practices
Create Specifications
  1. Collect context documents - Gather customer specs, emails, RFPs, research, design patterns, coding standards, technology choices, and constraints.
  2. Capture meeting transcripts - Record meetings and generate transcripts capturing discussions, decisions, clarifications, risks, and assumptions.
  3. Prepare the instruction/prompt - Specify the type of specification, structure, and required inclusions.
  4. Feed inputs into the LLM - Provide the prompt, context documents, and transcripts for the LLM to generate the first draft.
  5. Review the generated specification - Validate accuracy, completeness, feasibility, consistency, and identify gaps.
  6. Iterative evolution - Refine by repeatedly providing feedback until it reaches the desired quality.
  7. Finalize and baseline - Approve final version, store in repository, and generate derivative artefacts.

Measures & Goals

  • • Specification time reduced by 30%+
  • • Revision cycles reduced by 50%+

Important Considerations

Constraints

Understanding the limitations and challenges of AI-assisted software engineering

Context Window Limitations

AI models can only process a limited amount of text at once. Large specifications, long code files, or complex documents may exceed this limit, requiring chunking or summarization to maintain accuracy.

Data Privacy & Security

Sensitive information such as source code, customer data, or internal documents cannot be shared with AI tools unless they operate within approved, secure environments. Proper controls must be in place.

Hallucinations & Incorrect Outputs

AI may produce confident but incorrect or fabricated answers. Human review is essential to verify accuracy, prevent logical errors, and ensure outputs meet functional and quality expectations.

Dependency on Input Quality

The quality of AI output is heavily influenced by the clarity and completeness of inputs such as specifications, prompts, and guidelines. Poor or incomplete inputs lead to weak or inaccurate results.

Model Drift & Version Changes

AI tools evolve rapidly. Model updates or version changes can alter behavior, output style, or accuracy, affecting reproducibility. Teams must be prepared to adapt prompts and workflows when models change.
