When an important technical conversation happens in Slack—such as an architecture decision, a production debugging session, or an explanation from a senior engineer—how does your team turn it into durable documentation?
Who decides that the discussion is worth capturing, and who does the work of turning it into a useful page, ADR, runbook, ticket, or code documentation? Does this happen immediately, during a regular cleanup, or often not at all? Do senior engineers end up owning the knowledge, or is documentation capture shared across the team?
I'm especially interested in lightweight processes that work as engineering teams grow without creating a large additional documentation burden.

A practical trigger is better than a calendar-based cleanup. Give every important page an owner, and add a documentation check to the completion criteria for related work. If a ticket, epic, or architectural change is edited or completed, an automation can flag the linked page for verification and notify its owner.
Scheduled reviews are still useful, but time alone is a poor signal. A page that is two years old may still be accurate, while a page from last week may already be wrong after several scope changes. Change-driven reminders are less likely to become rubber-stamp exercises.
We separate documentation by how long it is expected to remain useful. Tickets capture temporary context and decisions needed to complete a piece of work. ADRs preserve the reasoning behind significant technical choices. Architecture docs describe the broader current system, while runbooks explain procedures that an experienced engineer outside the team would not know.
The person doing the work usually creates or updates the relevant document as part of that work. If the update is too large to handle immediately, we create a technical-debt item rather than pretending the gap does not exist. Most useful updates happen close to the change, while more permanent or auditable documents get reviewed periodically.
Senior engineers often do more of the reviewing and long-term maintenance, but the actual capture should be distributed. The people making changes have the most context, and junior engineers or new hires are valuable because they expose confusing or missing explanations.
Agreed templates reduce the mental overhead of deciding what to write. Lightweight ADRs, a simple architecture format, and incremental updates are usually enough. The goal is not to transcribe every conversation; it is to capture decisions, rationale, system changes, and operational steps that someone will genuinely need later.
Documentation works best as a shared responsibility tied to the work itself. Whoever changes a feature, makes an architectural decision, or modifies an operational process should update the related documentation. A team lead or project manager can make sure it happens, but they shouldn’t be the only person writing everything.
The simplest approach is to include documentation updates in the definition of done and review them alongside code and configuration changes. New hires can also improve onboarding material as they discover gaps. Automating generated material, such as API specifications, helps keep the manual workload manageable.
