Foundational Design

The Core Triad:
User, Data, & Task.

Before defining complex measures or building pipelines, every successful Data Product must master the intersection of the person using it, the job they need to do, and the exact information required to do it.

Data Product User, Data, and Task Metrics

The Three Pillars of Design

A data product is only as good as its alignment across these three elements. Miss one, and the product will fail to drive adoption.

The User

Who is consuming this data? You must deeply understand their technical proficiency, their daily workflows, and how they prefer to consume information.

Key Questions

  • Are they an Analyst, Exec, or ML Model?
  • What tools do they already use?
  • What is their data literacy level?

The Task

What is the "Job to be Done"? Data is useless unless it is applied to a specific action, decision, or automated process that drives the business forward.

Key Questions

  • Is this for operational action or strategy?
  • How frequently does this task occur?
  • What happens if the task is delayed?

The Data

What exact information is required to support the Task for the User? This dictates the schema, the latency, the history, and the quality SLA required.

Key Questions

  • Do they need real-time or daily batch data?
  • What level of granularity is required?
  • Are there PII/Security constraints?
Designing Output Ports

Where the Triad Intersects

The answers from the User, Data, and Task triad completely dictate how you engineer your Output Ports (how the data is delivered). A single dataset might need multiple output ports to serve different triads.

If you design a beautiful real-time API (Data) for a CFO (User) who just wants a monthly PDF report (Task), your product will fail.

Mapping the Triad to Architecture

Scenario A: The Executive

User: CMO (Non-technical)

Task: Monthly Budget Allocation

Data: Highly aggregated, historical

→ Build a curated BI Dashboard View.

Scenario B: The Application

User: Recommendation Engine (Machine)

Task: Serve live product suggestions

Data: Granular, sub-second latency

→ Build a high-performance REST API.

Stop Building in a Vacuum

Start defining your data products by focusing intensely on the User and their Task, before you write a single line of SQL.
