A brief history

NASA Flight Operations is the group of people who

• Plan human spaceflight missions
• Train astronauts
• Support astronauts during their missions via Mission Control Center (MCC)

Groups

This directorate is split into about 20 groups

We're in the Extravehicular Activity (EVA) group

(NASA-speak for "spacewalks")

How We've Always Done It

Folder Structures

What began as paper folders of typed documents ...

Grew to gigabytes of electronic folders

This led to problems

Directory trees are difficult to search

Multiple copies and versions of documents

• Which one do I trust?
• Do I have to update all of them?

Files are easily moved or deleted

The "Wiki Way"

• Search, don't sort
• Search content, not just file names
• A single portal for information
• Automated revision control
• Semantic linking
• Quantifiable accountability

Mission History

We created a page for each ISS and Shuttle mission. In each page, we set semantic properties for each crew member, flight controller, and relevant hardware item.

Mission History

We can then query for data ...

{{#ask: [[Category:Expedition]] 
|Mainlabel=Expedition
|? Commander
|sort = Mission start date
|order = asc
}}
							

Mission History

... and we can elegantly display this data on any page

Demo of Semantic MediaWiki

A scale of two wikis

• Wikipedia
• 1000s of active contributors
• Some pages have major coverage... some do not


• The EVA Wiki
• 47 active contributors
• 67272 edits
• 400k views in 3.5 years

Quantifying Accountability

1. Determine number of reviewers for each page
2. Determine a way to rate contributors
3. Combine (1) and (2) to identify weak points in our data
4. Address weak points

Extension:Watch Analytics

Watcher Distribution: December 2014

Watcher⬄page relationships

Accountability Emergency

Short term goals

1. Increase number of watchers for each page
2. Increase frequency of reviews performed on each page
3. Increase quality of reviews performed on each page

Rating reviewers and pages

1. Probability of correctness
2. Engagement Score

User Statistics

Culture Changes

Range of Response

• Early adopters
• Those that began using after some help and motivation
• Viewers, but not contributors
• Viewers, contributors, but not reviewers
• Stubborn, refuse to even view the wiki

User activity loops

• Tutorials, Screencasts, and Guided Tours
• Meeting Minutes
• Missions/EVAs
• Subject Matter Experts
• Pending Reviews
• Page Scores

What we've been missing

• Have we accounted for all four personality types?
  • Competition
  • Self-Expression
  • Exploration
  • Collaboration
• Have we provided for intrinsic motivation?
  • Competence
  • Autonomy
  • Relatedness

Gamification Framework

1. Define objectives
2. Delineate target behaviors
3. Describe players
4. Devise activity loops
5. Don't forget the fun
6. Deploy the appropriate tools
