Tom Smith explores an MIT research framework that organizes code into ‘concepts’ and ‘synchronizations,’ discussing its potential impact on AI coding tools, software visibility, and DevOps practices.

MIT Researchers Propose a New Way to Build Software That Actually Makes Sense

Most modern software is difficult to comprehend due to the fragmentation of features across multiple services and codebases, making maintenance and reasoning about system changes risky and opaque. MIT researchers, including professor Daniel Jackson and PhD student Eagon Meng, have presented a framework aiming to address these challenges.

The Problem with Current Software Design

Common application features—such as sharing or commenting—are typically spread across several code areas, which MIT refers to as ‘feature fragmentation.’ This distribution makes it hard for developers to understand how a feature works or how changes might affect overall system behavior, increasing maintenance complexity and unpredictability.

Concepts and Synchronizations: The Proposed Solution

  • Concepts: Self-contained modules responsible for a single task (e.g., ‘sharing’, ‘liking’). Each has isolated state and logic, reducing dependencies.
  • Synchronizations: Explicit rules or domain-specific code that define how concepts interact. Instead of hidden integration logic, synchronizations make connections between concepts clear and visible.

Meng suggests that code should be ‘read like a book,’ where logical relations are understandable at a glance. By making these dependencies explicit, the system is easier to reason about and maintain.

Benefits for AI Coding Tools and Large Language Models

  • With clear synchronizations, LLMs and AI tools have better visibility into how features interconnect. This helps automated tools generate or modify code more safely, with fewer unexpected side effects.
  • The approach was tested in a case study, showing centralized, testable feature modules instead of scattered logic.
  • Error handling and data management logic can be placed in synchronizations, reducing code duplication and making systemic behaviors more predictable.

Implications for DevOps Teams

  • High-level mapping lets teams anticipate the impact of changes before deployment, reducing regressions and improving trust in automated delivery paths.
  • According to industry perspectives, the explicitness of this model could allow automation tools to better reason about software behavior.
  • The framework could pave the way for ‘concept catalogs’—reusable, well-tested modules that can be assembled with clear rules.

Closing Thoughts

While the approach does not eliminate software complexity, it surfaces it in a more accessible manner. This visibility supports both human and automated reasoning, which is particularly valuable for organizations practicing DevOps and AI-assisted development.
