Friday: Impact Friday: The Impact Review

The council meeting is tomorrow. Comet pins the data story to the board, then stops.

"Wait," she says. "What happens after we share this? Could anything go sideways?"

Wren looks up from his clipboard. "What do you notice? That might be the best question anyone has asked all term."

Nova hovers over the board and projects two columns: helpful and harmful. "Would you like a hint?" she asks. "List what this report could change, for whom, and in ways nobody planned."

Comet uncaps a marker. "Data analyst, let's review the whole Commons Count, from the first question to the last graph."

Effects nobody planned

People create computing innovations. Not every effect is expected ahead of time.

One effect can help some people and harm others. It can even be both for the same person.

Innovations get used in ways their makers never intended. Responsible makers think about this, but no one can foresee every use.

Sharing results fast with many people can have big effects beyond the maker's control.

Computing has also increased creativity in fields such as medicine, engineering, communications and the arts.

Possible effect (made-up, from the Commons Count story)Who it might helpWho it might harm
The council adds longer evening hoursEvening membersKeeper Ines, who might work later
The graph is copied around townOther halls planning a surveyMembers, if readers think it speaks for the whole town
The council uses the survey to cut morning hoursNobody planned this useMorning members, who were under-heard
REVIEW THE EFFECTS
  • Read the question.
  • Tap your answer.
Longer evening hours help evening members but mean later work for Keeper Ines. What does that show?
Using the survey to cut morning hours was never the crew's plan. What is that?
What can the crew do before the graph spreads fast?
StatementTrue or false?
Every effect of an innovation can be planned ahead.?
Sharing results with many people fast can have effects beyond the maker's control.?
One effect can be helpful and harmful to the same person.?

WHY THIS EXERCISEAn impact review helps a team share work that does more good than harm.

Course review

  1. Data become information when people pull facts and patterns from them.
  2. Ask first, collect only what the question needs, and use IDs, not names.
  3. Clean data without changing their meaning, and log every choice.
  4. Graph honestly, starting bars at 0, with a title and a source.
  5. Typical values, models and audits each tell part of the story, with limits.
  6. Share totals, give credit, and review the impact before you publish.

On paper, make two columns, helpful and harmful. Add one new possible effect of Commons Count to each column.

What a project, data analyst. Tomorrow is the last Mission Quest: present your data story at home.
