What is Information Systems?


Study of ICT’s development and use in the real world of
people, e.g.


Systems development methods and their reshaping


ICT and global outsourcing


Business strategy and ICT


Mobile technology and work


ID cards debate

IS at the LSE


ICT in use influences and is influenced by the social
context as well as by its technical characteristics


We draw on the social sciences (e.g. economic, social,
organisational, and political viewpoints)


We have worked in, and done research on, complex
infrastructures:


knowledge management


financial networks


health information systems


systems development

source processes


Pegasus builds on and will contribute to this stream of
work

Why is GridPP interesting to us?


Our interest is in how complex infrastructures
develop and evolve


particle physicists are pragmatic: contrast to other developers
(e.g. consultancies, corporations)


particle physicists are distributed and have for a long time
worked together as a "virtual organisation"; of great interest to
others in e
-
science.


GridPP has to deliver on time for LHC

Pegasus Project


We aim to study GridPP’s approach to e
-
science
infrastructure development, deployment and use,
and
as a mix of technology, practices, knowledge, people,
cultures, institutions, and politics…



We study GridPP as a
means to “do” science
.



Relevant for improving the potential of other Grids,
and to inform other large infrastructures (e.g. NHS
“connecting for health”, financial clearing and
settlement …).

What are we planning to do?


We trace:


development of GridPP;


what influences the technology;


how GridPP comes to be used for the LHC;


how this use affects GridPP



We are interested not just in the rationalistic processes
of design, but in the emergent behaviours, the “drift” in
practices, the dynamic competences which evolve



For many areas of IS development these are crucial
issues:


global and distributed approaches, collaborations, and
contingent ways of processes of innovation

‘Data’ Collection


BUT…the particle detector is looking at “objective”
particles: we are looking at messy, complicated humans



We cannot do a science experiment


instead we
employ a technique from anthropology: Ethnography


Not devolved objective observers (we know that doesn’t work!)


observe, discuss, experience and participate


Interest in cultures, values, ways of working


Concerned with people’s interpretations


Confidentiality and Impartiality


Avoid bias from dominant opinions, or the researcher



We are not from particle physics or computer science


so we can and will ask the “stupid” questions

‘Data’ Collection


Over the next two to three years we will be:


Attending GridPP Meetings etc.


Visiting workplaces


Asking questions


Observing the technology in development and in use


Reading and analysing documents


Interviewing (usually around an hour)


Tape recording (and maybe even video!)


Taking lots of notes!



And analysing the results!

Specific Outputs


From all this observation we will write a set of “thick
descriptions” describing:


1.
How the needs of the LHC shape GridPP

2.
How GridPP is understood by, and comes to be used by,
particle physicists preparing for the LHC

3.
How GridPP is actually put to use by particle physicists in
research using the data from LHC



Using these reports to produce a framework and set of
guidance for others developing similar Grids (including
engineering, businesses and government).

Wider Contributions to IS


Existing theories of infrastructure suggest infrastructure
must be
(Star and Ruhleder)
:


Embedded inside both technologies and social arrangements


Built upon the installed base reflecting an inertia.


Transparent in use (and not reinvented for each task)


Only visible upon breakdown.


Reach beyond a single event or practice.


Learnt as part of “becoming” a member of a community.


Embodied in standards (negotiated with other infrastructure)



We aim to draw upon, and contribute to such literature
using, e.g. concepts such as bricolage, situated actions,
virtual organisations, translation and inscription, and
distributed cognition!

Finally...What’s in it for GridPP?


The lessons of your hard work and insight will of value to
others following (after) you.


Help promote the work of GridPP.


Help demystify GridPP, and let the public learn about the
process of technological innovation and contemporary
science.


Help GridPP to reflect on its practices, and improve its
own understanding.


Provide an alternative perspective on your work.
