Infrastructure

Applications

We all have one!PC + TV + Telephone

Take it with you!


Computers in everyday life


Convergence or Divergence?


• new definitional challenges

• moving from the factory to the service society

• the role of people and technology as institutionalised practices

• integration of discrete networks

• overcoming temporal and spatial boundaries

• mobility and use of mobile information technology

New issues on the agenda


Everything is connected to everything

• everything connected to everything else

• pervasive information infrastructures

• Internet, GSM, 3G, EDI, XML

• applications developed by cloning existing applications

• by “gluing” together existing components

• tinkering, or bricolage balanced with ‘rational’ design

• Services as interactions

“an act or performance by one party to another. Although the process may be tied to a physical product, the performance is essentially intangible…Services are economic activities that create value and provide benefits for customers at specific times and places”. Lovelock et al. (1999)

Services


• Encounters vs Relationships (Gutek)

• Discrete transactions and continuous delivery (Lovelock)

• Transactional vs Relational marketing (Coviello & Brodie)

• Transaction vs Relationship economics (Zuboff & Maxmin)

• Services (Grönroos, 2000; Kaitovaara, 2004)

• Intangibility

• Inseparability of production and consumption,

• Potential variability

• Perishability

• Lack of ownership

Services


•From systems to services

•SaaS = Software as a Service

•http://en.wikipedia.org/wiki/SaaS

•Web and Internet delivery

•Portfolios of services

•Alta Vista Search

•Amazon

•Google

•eBay

•Blogger

•Windows Live

•SaaCS = Software as a Customised Service

•Does IT Matter? (Carr)

Information Services

http://en.wikipedia.org/wiki/SaaS


Algorithms vs Objects

•“Algorithms are 'sales contracts' delivering an output in exchange for an input, while objects are ongoing 'marriage contracts'. An object's contract with its clients specifies its behavior for all contingencies of interaction (in sickness and in health) over the lifetime of the object (till death do us part).”

•(Wegner, 1997)

Digital Traces


Structure and Chaos

The world produces between 1 and 2 exabytes of unique information per year, which is roughly 250 megabytes for every man, woman, and child on earth. An exabyte is a billion gigabytes, or 1018 bytes. Printed documents of all kinds comprise only .003% of the total.

From Information to Communication


Mobility


•Various debates on “mobile ---” Technological aspects

- Mobile communication (Mobile phones)- Mobile computing (Wearable computing)- Mobile devices (PDAs), etc.

Social aspects- Mobile work (Telework)- Mobile office (Virtual office)- Mobile society (Nomadic society), etc.

An rapid upsurge of interest in “mobile ---”, but little debate on “what is mobility?”, “what does ‘being mobile’ mean?”

Mutual desire to be left alone

Prioritising threads of interaction. You want to get out. They want to get in or continue

You may want to get hold of them. You may want to include them.

Overload


•Diffusion of innovations

• Your first email, fax and phone conversation

•Domestication

• Integral part of daily practice

•Unintended consequences

• 2-3 hours overtime each day answering emails

•Instant availability

• Managing interaction

• Abandon, drown, postpone, filter, cope?

From Diffusion to Distraction
