Agenda (1)
the point of this lecture is demonstrate that choices in theory are not ever just technical choices but are also necessarily social choices
in the first part of the lecture we will look at information and revisiting Shannon & Weaver to discuss it political and social effects
as we will see these political and social effects are a result of individualism
![Page 6: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/6.jpg)
Clarke, R. J (2001) L951-05: 6
Agenda (2)
last week we discussed aspects of Design Problems and Solutions- neither are as simple as is claimed
we continue this theme in the second half of the lecture by looking at how to make ‘almost useless’ objects- this tells us a great deal about the design process
![Page 7: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/7.jpg)

Definitions of Information

Clarke, R. J (2001) L951-05: 8
InformationTwo Definitions
everyday sense of the term is qualitative- associated with meaning
in the theory of information (Shannon & Weaver), it is a technical term which describes only quantitative aspects of messages
![Page 9: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/9.jpg)
Clarke, R. J (2001) L951-05: 9
InformationTwo Definitions
ie. meaning of information in everyday language is different to meaning in the technical sense
does a manager mean the same thing as an IS developer- I think not!
but both have in common a sense of novelty
![Page 10: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/10.jpg)
Clarke, R. J (2001) L951-05: 10
Ordinary Meaning of Information
“communication of the knowledge or ‘news’ of some fact or occurrence” (OED)
‘news’ is central to its meaning, what is known already is not information
ie. has a semantic and pragmatic aspect
![Page 11: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/11.jpg)
Clarke, R. J (2001) L951-05: 11
Ordinary Meaning of InformationSemantics
information is a semantic property of a message because only meaningful messages can be informative
Semantics is defined as the study of meaninga branch of linguisticsthe study of relationships between signs
and symbols and what they represent
![Page 12: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/12.jpg)
Clarke, R. J (2001) L951-05: 12
Ordinary Meaning of InformationPragmatics
informativity depends on pragmatic factors of communication a sender who informs, and a reciever who notices
Pragmatics advocating behaviour that is dictated more by practicle consequences than by theory
![Page 13: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/13.jpg)
Clarke, R. J (2001) L951-05: 13
Information Probabilistic Definition
mathematical theory of communication defines information as a statistical property of a message, irrespective of its meaning
attempts have been made but they have failed!
![Page 14: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/14.jpg)
Clarke, R. J (2001) L951-05: 14
InformationProbabilistic Definition
Shannon & Weaver (1949) study of information relates signals to a general code of statistical averages
interest in the attempt to relate information to meaning has declined since the 1960s
attempts have been made to relate informativity to texts
![Page 15: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/15.jpg)
Clarke, R. J (2001) L951-05: 15
InformationProbabilistic Definition
Shannon & Weaver’s were interested in communications, mathematical engineering.
Again the IS discipline did not invent these ideas
but we got these ideas in a very pure form (just like general systems theory)
![Page 16: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/16.jpg)

Shannon & WeaverApplied to IS Development Practices (1)
whenever we talk about:an External Entity with respect to a
system (an IS or an organisation)Data Flow in any part of a manual or
computer based application
we will invariably be using Shannon & Weaver’s (1945) theory of communication
![Page 18: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/18.jpg)

Shannon & Weaver (1945)Diffusion to other Disciplines
Shannon & Weaver’s ideas also influenced many other disciplines as well
eg. media studies, linguistics, education etc. etc. and as these ideas were adopted they were also changed to suit the conditions of these other disciplines

Clarke, R. J (2001) L951-05: 27
Effects of Shannon & WeaverMany Effects
there are plenty of effects of the adoption of Shannon & Weaver’s (1994) model of information
most of them are bad:affects research in ISaffects IS methods that get developedincreases ‘individualism’ in organisationshas unfortunate political consequences
![Page 28: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/28.jpg)
Clarke, R. J (2001) L951-05: 28
Effects of Shannon & WeaverIS Research (1)
Effects the type of research questions that get posed in academic studies of IS
couches them in terms of individuals (Swanson 1987): What are the determinants of an
individual’s information system useWhat are the effects of an individual’s
information system use
![Page 29: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/29.jpg)
Clarke, R. J (2001) L951-05: 29
Effects of Shannon & WeaverIS Research (2)
this fits right into the individualism in existing IS research:questions are couched in terms of
individual performancehard to do (hard to get the kind of
workplace monitoring needed to measure individuals performance
so other features (surrogates) are used like ‘user satisfaction’
![Page 30: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/30.jpg)
Clarke, R. J (2001) L951-05: 30
Effects of Shannon & WeaverIS Research (3)
fits right into the individualism of a great deal of research in other areas eg./ management literature
therefore organisational theory has focused for the most part on individual information system use
![Page 31: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/31.jpg)
Clarke, R. J (2001) L951-05: 31
Effects of Shannon & WeaverIS Research (4)
areas of reseach effectively excluded include the study of CSCW, developed in Europe, which had a social focus
but latter appropriated in the US as Groupware
eg. Microsoft development of Windows for Workgroups!
![Page 32: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/32.jpg)
Clarke, R. J (2001) L951-05: 32
Effects of Shannon & WeaverIS Research (5)
another area that is devalued is software ergonomics which had a social emphasis (Turner & Karasek)
this kind of research direction (skewed towards individuals) does have real (ie. social and economic) effects
![Page 33: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/33.jpg)
Clarke, R. J (2001) L951-05: 33
Effects of Shannon & WeaverIS Research (6)
often systems incorporate workplace monitoring facilities (because its easy to do if you use a sender receiver model) eg./ Microsoft Mail; eg./ EFTPOS ckeckout systems eg./ Truck Scheduling Systems
![Page 34: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/34.jpg)
Clarke, R. J (2001) L951-05: 34
Effects of Shannon & WeaverIS Research (7)
the kinds of research which don’t tend to get as much attention are extremely important for organisations (Swanson 1987) eg.: organisational communicationorganisational semiotics
![Page 35: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/35.jpg)
Clarke, R. J (2001) L951-05: 35
Effects of Shannon & WeaverIS Methods
it helps to skew the types of IS methods that get produced and therefore used (many of them are developed in academic institutions
ie. the methods come with inbuilt with individualism as a theoretical assumption
![Page 36: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/36.jpg)
Clarke, R. J (2001) L951-05: 36
Effects of Shannon & WeaverPolitical Effects (1)
rather communication gets reduced to “the exchange of information between a sender and a receiver and the inference of meaning between organisational participants” (O’Reilly & Pondy 1980, 121)
inference = hint or imply
![Page 37: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/37.jpg)
Clarke, R. J (2001) L951-05: 37
Effects of Shannon & WeaverPolitical Effects (2)
if this model is about ‘transmission’ then who has the role of the sender becomes a political act (in an organisation or a society)
that is:who can ‘speak’who is allowed to ‘speak’who has the authority to ‘speak’
![Page 38: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/38.jpg)
Clarke, R. J (2001) L951-05: 38
Effects of Shannon & WeaverPolitical Effects (3)
in everyday life we know this to be true:when our parents speak we are
expected to obey “Little children should be seen and not heard”
when the teacher speaks you should be silent “No talking in class [except for me]”
![Page 39: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/39.jpg)
Clarke, R. J (2001) L951-05: 39
Effects of Shannon & WeaverPolitical Effects (4)
therefore by adopting a position about a communication model like Shannon & Weaver
we also adopt a theory of communication
which privaledges those who have the power to speak over those who may only be permitted to listen!
![Page 40: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/40.jpg)

Effects of Shannon & WeaverPolitical Effects (5)
in terms of systems analysis then, those who have the authority to speak in organisations are generally managers
check out any SDLC based methodology you like and you will find that most will just adopt what a manager thinks is required
![Page 41: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/41.jpg)

but, what if we want to develop a system for non-managerial users
how can we have participative methodologies which promote and enable others to speak!

Alternatives to Shannon & Weaver
Latter in the subject we will find a very good theory of communication, one which allows us to understand the use of informationbut its not based on a model of communication
like Shannon & Weaverit therefore changes and challenges what is
communicationif applied to IS development it changes almost
everything!

Almost Design: ‘Chindogu’
one way of demonstrating a point is by finding a negative example
an example which actually establishes the case for the truth of its opposite
Chindogu is an ‘art’ that applies humour to design

Almost Design: ‘Chindogu’
Chindogu involves the attempt to create almost useless objects
its name comes from two Japanese words (chin = "weird" dogu = "tool")
although based in Japan, it has an international following...

Almost Design: ‘Chindogu’
there is a book on Chindogu, and even an institute dedicated to it
there is also a website at http://info.pitt.edu/~ctnst3/chindogu.html

Chindogu Tenet 1
A Chindogu cannot be for real use. It is fundamental to the spirit of Chindogu
that inventions claiming Chindogu status must be, from a practical point of view, (almost) completely useless. If you invent something which turns out to be so handy that you use it all the time, then you have failed to make a Chindogu. Try the Patent Office.
![Page 52: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/52.jpg)
Clarke, R. J (2001) L951-05: 52
Chindogu Tenet 2
A Chindogu must exist.You're not allowed to use a Chindogu,
but it must be made. You have to be able to hold it in your hand and think 'I can actually imagine someone using this. Almost.' In order to be useless, it must first be.
![Page 53: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/53.jpg)
Clarke, R. J (2001) L951-05: 53
Chindogu Tenet 3
Inherent in every Chindogu is the spirit of anarchy.Chindogu are man-made objects that
have broken free from the chains of usefulness. They represent freedom of thought and action: the freedom to challenge the suffocating historical dominance of conservative utility; the freedom to be (almost) useless.
![Page 54: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/54.jpg)
Clarke, R. J (2001) L951-05: 54
Chindogu Tenet 4
Chindogu are tools for everyday life. Chindogu are a form of nonverbal
communication understandable to everyone, everywhere. Specialised or technical inventions, like a threehandled sprocket loosener for drainpipes centred between two under-the-sink cabinet doors (the uselessness of which will only be appreciated by plumbers), do not count.
![Page 55: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/55.jpg)
Clarke, R. J (2001) L951-05: 55
Chindogu Tenet 5
Chindogu are not for sale. Chindogu are not tradable commodities.
If you accept money for one you surrender your purity. They must not even be sold as a joke.
![Page 56: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/56.jpg)
Clarke, R. J (2001) L951-05: 56
Chindogu Tenet 6
Humour must not be the sole reason for creating a Chindogu. The creation of Chindogu is
fundamentally a problem-solving activity. Humour is simply the by-product of finding an elaborate or unconventional solution to a problem that may not have been that pressing to begin with.
![Page 57: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/57.jpg)
Clarke, R. J (2001) L951-05: 57
Chindogu Tenet 7
Chindogu is not propaganda. Chindogu are innocent. They are made
to be used, even though they cannot be used. They should not be created as a perverse or ironic comment on the sorry state of mankind.
![Page 58: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/58.jpg)
Clarke, R. J (2001) L951-05: 58
Chindogu Tenet 8
Chindogu are never taboo. The International Chindogu Society has
established certain standards of social decency. Cheap sexual innuendo, humour of a vulgar nature, and sick or cruel jokes that debase the sanctity of living things are not allowed.
![Page 59: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/59.jpg)
Clarke, R. J (2001) L951-05: 59
Chindogu Tenet 9
Chindogu cannot be patentedChindogu are offerings to the rest of the
world - they are not therefore ideas to be copyrighted, patented, collected and owned.
![Page 60: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/60.jpg)
Clarke, R. J (2001) L951-05: 60
Chindogu Tenet 10
Chindogu are without prejudiceChindogu must never favour one race or
religion over another. Young and old, male and female, rich and poor - all should have a free and equal chance to enjoy each and every Chindogu.
![Page 61: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/61.jpg)
Clarke, R. J (2001) L951-05: 61
Chindogu and Design
by trying to create almost useless objects, Chindogu teaches us about what design is (a negative example)
it also demonstrates how the design process is a social phenomenon
![Page 62: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/62.jpg)

Chindogu and DesignClass Exercise
some examples of Chindogu will be shown, but for each consider the following questionswhat does a Chindogu designer need
to know about a situation and a culture and in order to design the each Chindogu
why is each Chindogu nearly useless rather than completely useless!

Methodologies & Ontology (1)
but methodologies also consist of “coherent bundles [of concepts] which constitute a perspective on social life” (Kling 1980, 151)
ontology: ‘the set of entities presupposed by a theory’
![Page 66: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/66.jpg)
Clarke, R. J (2001) L951-05: 66
Methodologies & Ontology (2)
most methodologies (especially process & data-oriented) consider the world to be ‘a priori’
that is ordered logical, rule-based, natural- however, if systems development is really a social process- then this cannot be true!
![Page 67: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/67.jpg)
Clarke, R. J (2001) L951-05: 67
Methodologies & Ontology (3)
most methodologies do not state their ontology
most academics who construct methodologies don’t consider this to be important- they are wrong!
we have seen that ‘everything has a theory’
![Page 68: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/68.jpg)
Clarke, R. J (2001) L951-05: 68
Methodologies & Ontology (4)
we can apply this idea to methodologies
just because its theory about the world is not made explicit doesn’t mean there isn’t one
in fact it guarantees that there is a politically conservative, naive, common sense view of the world informing the methodology!
![Page 69: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/69.jpg)
Clarke, R. J (2001) L951-05: 69
Methodologies & Ontology (3)
even good methodologies (eg. SSM) get this wrong
SSM views the world is a common sense view
the world is real, but people have a range of perspectives from which they can view it!
![Page 70: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/70.jpg)
Clarke, R. J (2001) L951-05: 70
Methodologies & Ontology (3)
this contains a contraction- why do you need to insist on there being a ‘real world’ somehow separate from a ‘social world’
the social world is real & has ‘real consequences’
try to treat the world as socially constructed
![Page 71: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/71.jpg)
Clarke, R. J (2001) L951-05: 71
Systems Design as Social Activity (1)
social processes are always at work during the analysis, design, development and implementation of systems
all these activities take place in organisational and institutional settings
![Page 72: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/72.jpg)
Clarke, R. J (2001) L951-05: 72
Systems Design as Social Activity (2)
need to ‘locate’ social processes and human interactions within historical and organisational contexts
some justification is required for this approach...
![Page 73: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/73.jpg)
Clarke, R. J (2001) L951-05: 73
Systems Design as Social Activity (3)
systems development, implementation and maintenance is highly dependent on the skills of large numbers of IT professionals
communication processes and social interactions within the developer community are of great importance
![Page 74: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/74.jpg)
Clarke, R. J (2001) L951-05: 74
Systems Design as Social Activity (4)
changes in systems development practices, whether related to technology or organisational issues, are always driven and mediated by social factors
eg./ shift from ad-hoc methods to SDLC, shift from C to C++ are all socially motivated
![Page 75: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/75.jpg)
Clarke, R. J (2001) L951-05: 75
Systems Design as Social Activity (5)
systems development is a complex bridging process linking areas of specialized and diverse expertise; the domain of the IT professional and the domain of the user
systems development concerns itself with IT innovation, application and diffusion- all social
![Page 76: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/76.jpg)
Clarke, R. J (2001) L951-05: 76
Summary so far...
So far we have treated systems development as if it is a technical science
but, it is actually social and its not a science either!
so what is it that we do when we design a CBIS?
![Page 77: Clarke, R. J (2001) L951-05: 1 Critical Issues in Information Systems BUSS 951 Lecture 5 Design 2: Social Practices.](https://reader030.fdocuments.net/reader030/viewer/2022032800/56649d2c5503460f94a01c8e/html5/thumbnails/77.jpg)
Clarke, R. J (2001) L951-05: 77
Summary
we will see in coming weeks that not only is systems development not a science, but...
if we theorise the social aspects of systems development and use, we can use this to create systems
knowing about the social world is enough to create CBIS!
