Design related study

• The object of design study is variable by
  definition
• Social and physical context delimits that object
• But context is everything
• How to get grip on that vague concept first?

3
Getting grip on future context

• distinguish
• Levels of scale (largest frame and smallest
  detail)
• Layers of social and physical context
• Language games supposingprobable, desirable or
  possible future contexts

4
LEVELS OF SCALE

• The object of design is variable
• But at least the order of size could be
  determined
• Then, anything larger or smaller is context
• Determining external variableswith hidden
  assumptions models for anything outside the
  object of study
• But conclusions from outside and inside may
  differis a ball convex or is it concave?

5
Scale paradox

• On the level of one spot you should conclude
  difference
• On the level of 7 spots you should conclude
  equality
• Reversal of conclusions may appear by a factor 3
  radius
• So, the order of size determines your view

6
Levels of scale to be aware of

• Different scales mean different legend units,
  categories, views, approaches, conclusions

7
Names and boundaries of size categories

• In this presentation nominal values indicatean
  order of size
• They are elastic
• 10m means somethingin between3m and 30m

8
A frame 100x the granule of a drawing
representing a building

• r/R determines the resolution of a drawing or
  discourse,
• the resolution of the argument

9
Locating a spatial object of design study within
its context

• If the scale (frame O and granule o) of the
  object is determined, then the rest is context
• The programme is a set of desired impacts

10
The object (O,o) its inconvenient (I) and
profitable (P) impacts located

• The programme of requirements is a set of desired
  impacts
• Locate them to locate the stakeholders
• Perhaps they are willing to pay the project!

11
LAYERS OF SOCIAL AND PHYSICAL CONTEXT

• Managerial/governmental contexts (active ltgt
  passive)
• Cultural contexts (innovative ltgt traditional)
• Economic contexts (growing ltgt declining)
• Technological contexts (separating ltgt connecting)
• Ecological contexts (differentiating ltgt
  equalizing)
• Spatial contexts (accumulating ltgt dispersing )

12
The future context determines the possibility of
realization

• The supposed future impacts will be different in
  different future contexts
• For example, the economic impact will be
  different in a growing local economy compared
  with a declining local economy
• So, you have to specify your suppositions about
  the probable future within which your object will
  have its impacts

13
Making suppositions about the context more
explicit to assess the impacts

• You cannot estimate the impacts without
  suppositions about the context
• Make them explicit before study

14
Suppositions about management context on any
relevant level of scale

• Is it an active management context with much
  initiatives? Give it sign ! in the scheme
• Is it a passive administrative context of just
  checking and controlling the rules? Note ?
• In the last case initiative should be part of
  your project to get the intended impacts realized
• And they can be different on different levels of
  scale

15
Local initiative expected
16
Suppositions about cultural context on any
relevant level of scale

• For administration and management we took
  opposites of initiative (!) and checking and
  controlling (?)
• They apply on any level of scale.
• But what about culture? For example, what does
  culture mean on the level of building material
  (R 3mm)?
• To include any level of scale, we propose
  'traditional' (lt) opposed to 'innovative' or
  'open to experiments' (gt)

17
Traditional building expected
18
Suppositions about economic context on any
relevant level of scale

• The economic context is shortly characterized by
  growing () and declining (-)
• That can be different on different levels of
  scale
• The economic context could be a declining
  neighborhood within a prosperous municipality
• A context like that will determine a project or
  an assignment substantially

19
Suppositions about technological context on any
relevant level of scale

• Which extremes could be found for the
  technological context?
• internal separation (/) or combination (X) of
  functions is an essential design choice on any
  level of scale
• Is it usual in the future context to separate or
  combine
• pressure and tension in construction (R 10cm)
• separating and supporting constructions (R 1m)
• cooking and eating in the kitchen (R 3m)
• living and work in my neighborhood (R 300m)?

20
Suppositions about ecological context on any
relevant level of scale

• In ecology we suppose diversity or heterogeneity
  () as most universal context variable, opposed
  to equality or homogeneity ()
• Which kind of diversity that concerns could be
  elaborated later
• diversity of plants, animals, or people
• households with the same or different age,
  lifestyle or role-emphasis
• for example familism versus careerism

21
Suppositions about spatial context on any
relevant level of scale

• Mass can accumulate, concentrate (C) or disperse
  (D) in space and time
• That is an essential design context factor
• What is called mass could be specified later
• State of dispersion of legend units in a drawing
  are characteristics of form and composition

22
Accumulation or sprawl R30km

• Towns can concentrate, disperse or be subject to
  a policy in between
• In which spatial context your project will have
  its impacts?

23
States of dispersion r100m

• Houses can concentrate or disperse
• In which spatial context your project will have
  its impacts?

24
States of dispersion in the same density on one
level of scale

• Anything can concentrate or disperse on any level
  of scale
• State of dispersion and density are different
  concepts

25
One million people in two states of distribution
on two levels of scale
26
Making suppositions about the context more
explicit to assess the impacts

• You cannot estimate the impacts without
  suppositions about the context
• Make them explicit before study

27
Locating the object (O,o) its impacts (I) and the
origin of a programme (P)

• The programme is a set of desired impacts
• Locate them to locate the stakeholders
• Perhaps they are willing to pay the project
• Dont forget the other impacts

28
LANGUAGE GAMES

• One cannot agree with a proposition without
  determining its modality
• I agree its is true or probable is different
  from
• I agree its desirable
• I agree its possible
• Probable but not desirable detects a problem
• Desirable but not probable detects an aim

29
Three language games in a planning team

• Different specialists use different language
  games
• The same concepts may mean different things
  uttered by politicians, scientists or designers

30
Subtracting futures to outline fields of problems
and aims

• If a statement is probable but not desirable,
  then its a problem
• The reverse its an aim

31
Adding possible futures, skipping the impossible
ones

• Probable but not desirable futures are relevant
• Desirable but not probable ones also

• Probable and desirable futures are not relevant
• Impossible and desirable ones also

32
Proposals for design studies with many
specialists and stakeholders

• Struggle with
• A variable object
• Uncertain impacts hitting different stakeholders
• They need an agreement about a supposed future
  context, properly distinguishing relevant
• Levels of scale
• Layers of social and physical context
• Language games (modalities)
