Task complexity
Many tasks transcend the capability of a single hhuman
“..this implies, that techniques for dividing effort and knowledge are fundamental to the creation of highlyknowledge are fundamental to the creation of highly complex things” [Baldwin & Clark]
Two points on spectrum of artifact complexityMade by a single person division of labourMade by a single person division of labourComprehended by a single person division of knowledge and effort that go into design creation

Task/artifact complexity according to Baldwin and Clark
Complex products e g computer software vehiclep p(Division of design andproduction required)
e.g. computer, software, vehicle
Big products(Division of labour)
e.g. house, bicycle
Simple productsSimple products(can be constructed bya single person)
e.g. hammer, table

Task dependencies
ClassificationTight vs. loose couplingRoutine vs. non‐routineSynchronous vs. asynchronous
Th t f t k d d i [Th ]Three types of task dependencies [Thompson]Pooled– sharing of some resources from a common pool– few coordination requirementsfew coordination requirementsSequential– output of one process are input for another– e.g. assembly line
i lReciprocal– tasks are mutually dependent– e.g. "intensive technologies"– high coordination efforthigh coordination effort

Computer‐supported cooperative work
CSCW deals with understanding social interaction, design implementation and evaluation of technical systems thatimplementation and evaluation of technical systems that support social interaction (Gross & Koch)
„how collaborative activities and their coordination can be supported by means of computer systems“ (Carstensen & Schmidtsupported by means of computer systems (Carstensen & Schmidt 02)
G i ft h d d i t tGroupware is software, hardware and services to support groups [to achieve common goals]
Main property is not to isolate users but mutually inform them (co‐i ) (G & K h)existence, awareness) (Gross & Koch)
Groupware functionality can be realized an own class of systems, but also embedded as „feature“ of other software

Definition of Tim O‘Reilly: "Web 2 0 is the business revolution in the computer industry caused by theWeb 2.0 is the business revolution in the computer industry caused by the move to the internet as platform, and an attempt to understand the rules for success on that new platform. Chief among those rules is this: Build applications that harness network effects to get better the more peopleapplications that harness network effects to get better the more people use them.“
Tim Bernes‐Lee: Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0 is of course a piece of jargon, nobody even knows what it
Tim O'Reilly (2006-12-10). Web 2.0 Compact Definition: Trying Again

The Semantic Web is not a separate Web but an extension of the current one in which information is given well‐defined meaning bettercurrent one, in which information is given well defined meaning, better enabling computers and people to work in cooperation. [Tim Berners‐Lee]

Groupware challenges (1) [Grudin 94]
Disparity of contributors and beneficiariesAdditional effort for some users to add informatione.g. group calendar, file share, presence awareness, annotationannotation…Often managers are profiting
Critical massM t i l f l h t i b fMost groupware is only useful when a certain number of users participatese.g. choice of instant messager, calendar…e.g. choice of instant messager, calendar…

Groupware challenges (2)
Social, political and motivational factorsGroupware often deals with critical soft“ information that peopleGroupware often deals with critical, „soft information, that people do not want to make explicite.g. presence awareness, meeting priority
Exception handlingHuman experience about how processes work is hard to capture
Infrequently used featuresG h ld b d fi iti d ld l ( d iGroupware should by definition used seldomly (reduce expensive coorination by decoupling work)

Groupware challenges (3)
Difficult to evaluateTask analysis for groups is more difficult than for single users
Evaluation takes longer (due to usage frequency)
Breakdown of intuitive decision makingManangers decide for software that is good for themManangers decide for software that is good for them
They underestimate the downside in the case of groupware
Similar for developers, who are used to design single user p , g gapplications

Managing acceptance as a challenge for developersdevelopers job does not end with „shipping the product“
product is only a success, if it improves group performance not only determined by technical features / not predictable
