Efficient

First wave, Controlled experiments (Speed and accuracy), e.g. KLM A/B Test (Summative Empirical)

• y2018p27q8 (c)
  • practical steps

  • and the kind of recommendations to make
• y2019p7q9 (d)
  • viscosity
• y2020p7q9 (e,f)
  • strengths and weakness

Meaningful

Second wave, ethnography (Empirical)

• y2020p7q9 (b)
  • empirical, observation of a phenomena in the world
• y2018p27q8 (b)

Complex System

notational activity, CDN

• y2018p27q8 (a)
  • hidden dependencies ↑ viscosity ↑ visibility ↓
  • mitigation
• y2019p7q9 (c,d)
  • premature commitment / viscosity ↓ hidden dependency ↓
  • notational activity (exploratory design, open)
• y2021p7q9 (d)
  • abstraction ↑ , viscosity ↓, premature commitment ↑, hidden dependency ↑, diffuse ↑
  • notational activity (modification, open)
• y2020p7q9 (c-d)
  • role-expressiveness/secondary notation ↑ diffuseness ↑
  • notational activity (search)
