A Software Design Specification (SDS) is one of the most important documents produced during a software project. It serves as the definitive technical description of how a system is intended to work, why certain decisions were made, and how various components interact with each other. When maintained well, it forms the foundation for development, testing, onboarding, auditing, and future evolution of the system.
RFCs — Request for Comments — are one of the most powerful tools for teams trying to make better architecture and design decisions without descending into endless meetings or tribal knowledge.
Architecture Decision Records (ADRs) are the heartbeat of traceable system design. They’re where decisions get captured, debated, and explained — not just what was chosen, but why. Without ADRs, teams rely on Slack archaeology and hearsay to understand key technical moves.
Every Docs-as-Code journey starts with good intentions. But without structure, even the most motivated team quickly hits friction. What’s the right format for an ADR? Where should we store risk logs? Who owns what, and how do we make it visible?
Tools are easy. Culture is hard.
When you're building a product platform that spans firmware, application logic, cloud APIs, and customer-specific integration layers, documentation can quickly become fragmented and inconsistent.
Docs-as-Code done well can transform documentation from a last-minute task into an essential, integrated part of your engineering system. But when done badly — or worse, indifferently — it introduces a new layer of confusion, drift, and friction.
Markdown has become the lingua franca of technical documentation — and with good reason. It's lightweight, portable, and readable in its raw form. But for engineering teams building large, interrelated systems, plain Markdown often isn't enough.
Architectural documentation has a bad reputation. People write it, forget it, and then complain that “it’s out of date” or “no one uses it.” That’s not a failure of documentation — it’s a failure of process and ownership.
Documentation often gets left behind in Agile workflows. Burndown charts don’t track missing architecture decisions. Velocity doesn’t drop because your API spec is a week out of date. So unless you actively build documentation into your Agile flow — it doesn’t happen.
