How to Choose a Decision Record Platform
A good Decision Record platform keeps the reasoning behind a decision findable and honest for as long as the decision matters. Judge each candidate on eight criteria:
- It covers every kind of decision
- Every record has the same structure
- Records are sealed and superseded, never edited
- Premises are tracked separately
- Expected outcomes are checked against what happened
- The record says who decided
- AI agents can read it as a record
- Capture happens where the work happens
We build Memolok, a Decision Record platform, so the end of this page applies the same eight criteria to it.
Decision Record platform
Software built to capture, keep, and serve decision records, so the reasoning behind a choice can be found and trusted long after it was made.
First, Match the Tool to Your Decisions
Not every team needs a dedicated platform. The right tool depends on which decisions you need to keep and who needs to read them later.
| Your situation | What usually works |
|---|---|
| Engineering decisions only, read by the same team | Architecture decision records (ADRs): short text files software teams keep next to their code |
| A running list of what was chosen and when | A decision log in a spreadsheet or a wiki |
| Decisions across the business that people and AI agents rely on months later | A Decision Record platform |
The criteria below are for the third situation, where a record has to stay trustworthy after the people who made the decision have moved on.
The Eight Criteria
1. It Covers Every Kind of Decision
Decision records started with architecture decision records in software teams, and the practice works for any decision. A platform limited to code leaves pricing, hiring, supplier, and policy decisions with nowhere to go.
- Check: can a product, commercial, or operational decision be recorded in the same place and the same shape as a technical one?
2. Every Record Has the Same Structure
Free text makes every record a different shape, so nothing distinguishes a rejected option from a footnote. A fixed structure is what makes records comparable and queryable.
- Check: does every record hold the need, the alternatives and why they lost, the premises, the status, the expected outcomes, and what was deliberately left open?
3. Records Are Sealed and Superseded, Never Edited
A record that can be edited after the fact tells you what someone believes now, not what was decided then. A trustworthy record is fixed once made; a later decision supersedes it, meaning a newer record replaces it and links back, and both stay visible.
- Check: can a committed decision be silently rewritten, and can you see which decision is currently in force without reading every record?
4. Premises Are Tracked Separately
Decisions rest on facts: a budget, a contract term, a regulation. When one changes, the decisions standing on it may no longer hold.
- Check: when a premise is corrected, does the platform show which decisions rested on it?
5. Expected Outcomes Are Checked Against What Happened
Writing down what you expected at the moment of the decision is what lets you tell bad luck from bad reasoning later.
- Check: is the expected outcome a field you can come back to and compare with the result, or a sentence in a document nobody reopens?
6. The Record Says Who Decided
Accountability that lives in a version history or someone's memory disappears with the people involved.
- Check: does each record carry who raised the question, who framed it, and who committed to the decision?
7. AI Agents Can Read It as a Record
When an AI agent acts on an organization's past decisions, what it reads matters. An agent reading a wiki page reconstructs a story from prose; an agent reading a structured record gets the decision, its status, and its reasons.
- Check: can an AI agent query decisions directly, for example over the Model Context Protocol (MCP), the open standard AI assistants use to connect to other tools, and tell a current decision from a superseded one?
8. Capture Happens Where the Work Happens
A record that takes a separate trip to a separate tool is easy to skip. Capture that sits inside the conversation where the decision is made removes that trip.
- Check: can a decision be captured from the tools your team already works in, with a person approving it before it is recorded?
How Memolok Meets These Criteria
| Criterion | Memolok |
|---|---|
| Every kind of decision | Technical, product, and business decisions in one place, in one shape |
| Same structure | Every record has the same six parts: need, alternatives, premises, decision, expected outcomes, open questions |
| Sealed, not edited | Approved records are frozen; a later decision replaces one with a new record, and both stay visible |
| Premises tracked | When a fact a decision rested on changes, every decision that relied on it is flagged |
| Outcomes checked | What you expected is written down when you decide, then compared with what actually happened |
| Who decided | Who raised it, who framed it, and who committed are part of the record |
| Readable by AI agents | AI agents ask over MCP and get the current decisions, with their status and reasons |
| Capture in the work | Runs inside Claude, whether you use Claude chat, Claude Code, or Cowork; a person approves every record |

Common Questions
What is a Decision Record platform?
Software built to capture, keep, and serve decision records: what was decided, what else was considered, what was known at the time, and what was expected to happen. Its job is to keep that reasoning findable and trustworthy for as long as the decision matters.
Which Decision Record platform should I choose?
It depends on which decisions you need to keep and who will read them later. For engineering decisions read by the same team, architecture decision records kept as text files beside the code, managed with a command-line ADR tool, are usually enough. For a running list of what was chosen and when, a spreadsheet or a wiki page works. For decisions across the business that people and AI agents rely on months later, choose a Decision Record platform that meets the eight criteria on this page.
Do I need a dedicated platform, or is a wiki enough?
A wiki or a spreadsheet is enough for a running list of decisions read by the people who made them. A dedicated platform earns its place when records must stay trustworthy for readers who were not there, including AI agents: that takes sealed records, a status you can query, and premises and outcomes you can check. See what you use today for where a wiki falls short in detail.
Is a Decision Record platform only for software teams?
No. The practice began with architecture decision records in software teams, and the same structure works for any decision someone will later need the reasons for, from a price change to a hire to a policy an AI agent enforces. See the Product page for what a decision record is.
