Semantics-Driven Development (SDD): A brief introduction

What is Domain-Driven Design (DDD)

A definition of DDD as a software design discipline

Readme Driven Development

I hear a lot of talk these days about TDD and BDD and Extreme Programming and SCRUM and stand up meetings and all kinds of methodologies and techniques for developing better software, but it’s all irrelevant unless the software we’re building meets the needs of those that are using it. Let me put that another way. A perfect implementation of the wrong specification is worthless. By the same principle a beautifully crafted library with no documentation is also damn near worthless. If your software solves the wrong problem or nobody can figure out how to use it, there’s something very bad going on.

Understanding Spec-Driven-Development: Kiro, spec-kit, and Tessl

Notes from my Thoughtworks colleagues on AI-assisted software delivery

The semantics of clear, a specification language

This paper gives a semantics for the Clear language for specifying problems and programs, described by Burstall and Goguen in 1977. A blend of denotational semantics with categorical ideas is used.

Test-Driven Approaches to Software Engineering with Large Language...

Tests increasingly participate in the decisions made by large language models and software engineering agents. They specify intended behavior, guide program construction and repair, select...

agentlanguages.dev — Programming languages designed for AI agents to write

A community-edited catalogue of programming languages designed for AI agents to author code, organised around three philosophical camps: syntactic, verification, and orchestration.

What Kind of Programming is Natural Language Programming?

In previous posts I’ve written about Natural Language Programming, Dijkstra’s Ghost – the End of The Symbolic Supremacy and Ephemeral Editable Specifications (aka Extract, Edit, A…

Tending Your Software Garden

Software: do you write it like a book, grow it like a plant, accrete it like a pearl, or construct it like a building? As Steve McConnell notes in Code Complete 2, there’s no shortage of software development metaphors: A confusing abundance of metaphors has grown up around software

Domain-Driven Design: Tackling Complexity in the Heart of Software

Domain-Driven Design fills that need. This is not a book about specific technologies. It offers readers a systematic approach to domain-driven design, presenting an extensive set of design best ...

Software Is Made Between Commits

From the Zed Blog: Agents turned the conversation into the real source of our software. DeltaDB is the version control built for it.

Design system doc spec 0.15.2

A machine-readable format for design system documentation. DSDS structures components, tokens, themes, foundations, patterns, and guides as a single source of truth for humans, parsers, and agents.

Specification by example

Specification by example (SBE) is a collaborative approach to defining requirements and business-oriented functional tests for software products based on capturing and illustrating requirements using realistic examples instead of abstract statements. It is applied in the context of agile software development methods, in particular behavior-driven development. This approach is particularly successful for managing requirements and functional tests on large-scale projects of significant domain and organisational complexity.[1]

Software Design is Knowledge Building

The product of software development is not code but a mental model, a theory: a specific way of explaining the world.
