Data lifecycle and flow

Data starts at collection, gets stored, processed, shared, and eventually archived or deleted.

This module

Data roles and responsibilities

Roles exist so someone is accountable for quality, access, and change.

Next

Foundations of data ethics and trust

Ethics matters from the first data point.

Progress

Mark this module complete when you can explain it without rereading every paragraph.

Why this matters

Data owners make decisions about purpose and access.

What you will be able to do

  • 1 Explain data roles and responsibilities in your own words and apply it to a realistic scenario.
  • 2 Data work improves when decision rights and responsibilities are explicit.
  • 3 Check the assumption "Decision rights are explicit" and explain what changes if it is false.
  • 4 Check the assumption "Consumers can report issues" and explain what changes if it is false.

Before you begin

  • No previous technical background required
  • Read the section explanation before using tools

Common ways people get this wrong

  • Everyone responsible means no one responsible. When responsibility is shared, fixes are delayed. Make ownership clear.
  • Unowned breaking changes. If producers change fields without notice, downstream systems fail quietly.

Roles exist so someone is accountable for quality, access, and change. Data owners make decisions about purpose and access. Data stewards guard definitions, metadata, and policy. Data engineers build and maintain pipelines. Data analysts turn data into insights. Data consumers use the outputs responsibly. When roles blur, pipelines stall, privacy is ignored, or dashboards contradict each other.

Mental model

Ownership prevents chaos

Data work improves when decision rights and responsibilities are explicit.

  1. 1

    Owner

  2. 2

    Steward

  3. 3

    Producer

  4. 4

    Consumer

Assumptions to keep in mind

  • Decision rights are explicit. Someone decides when a definition changes and when a dataset is fit for purpose.
  • Consumers can report issues. If users cannot report problems, you only learn when outcomes fail.

Failure modes to notice

  • Everyone responsible means no one responsible. When responsibility is shared, fixes are delayed. Make ownership clear.
  • Unowned breaking changes. If producers change fields without notice, downstream systems fail quietly.

What does a data owner decide

Purpose and access.

What does a data steward maintain

Definitions, metadata, and policy alignment.

What does a data engineer build

Pipelines and storage that move and prepare data.

What does a data analyst do

Turns data into insights and stories.

Who is a data consumer

Anyone using the outputs responsibly.

Scenario. A dashboard number looks wrong. What is a sensible first move before arguing

Ask for the definition and lineage. Then involve the owner or steward for meaning, and the engineer for pipeline evidence.

What happens when roles blur

Confusion, stalled work, or risky decisions.

Artefact and reflection

Artefact

A short module note with one key definition and one practical example

Reflection

Where in your work would explain data roles and responsibilities in your own words and apply it to a realistic scenario. change a decision, and what evidence would make you trust that change?

Optional practice

Pair scenarios with the role responsible for the next action.
