This February 2021 archive item used a hierarchy of needs to explain why an AI project depends on work that happens before model development. Its foundation was reliable data collection and infrastructure.
Work up from the foundation
The sequence moved from collecting data to storing and transporting it, then cleaning and analysing it. Features, labels and simple models came next. Those early models provide a baseline against which a more complex approach can be judged.
Readiness includes responsibility
The original article also highlighted bias and the need to communicate uncertainty to stakeholders. A sophisticated model cannot compensate for unrepresentative inputs or an unclear objective. For product teams, the framework is a way to identify the next missing capability: sometimes the most valuable work is fixing collection or making data accessible, rather than training another model.
