Complex Adaptive System Definition
|
is a theory to explain emergent phenomena observed in systems composed of interacting adaptive agents.
|
|
Key idea RBV
|
Firms are heterogenous in terms of resources they control. Resources are how they sustain competitive advantage.
|
|
Attributes of Resources that Generate Sustained competitive advantage RBV
|
Valuable, Rare, Imperfectly imitable, non-substitutable
|
|
RBV in IS
|
Mainly used in value of IT literature
|
|
Key Articles
|
Authors RBV,Barney 1986 (founder), Hulland 2004 (IS extension)
|
|
Extensions RBV
|
Resource complementarity, dynamic environment
|
|
Importance of TAM
|
First IS theory. Fell out of favor after overuse.
|
|
Key Articles, Authors TAM
|
Davis 1989, 1991, Venkatesh 2003
|
|
Key Articles, Authors SET
|
Homans (founder), Blau (quantified the theory)
|
|
Roots SET
|
rational choice theory (microecon), learning behavior (social psychology), power (sociology)
|
|
Basic Idea SET
|
Value = Rewards – Costs (rewards and costs can be tangible or intangible. Rules govern the exchange like reciprocity, social norms... )
|
|
Assumptions SET
|
1- individuals seek rewards and avoid punishments 2- Individuals choose the exchanges that maximize their utility 3- Individuals have access to info on exchanges. 4 – individuals are goal oriented 5 – Value standards are dynamic. 6 – Repetition creates patterns and develop social structures.
|
|
SET in IS
|
Used in outsourcing and adoption
|
|
Key Articles Authors TCE
|
Coase (1937 founder), Malone et al. (1987 IS implementer)
|
|
Basic Idea TCE
|
Using market mechanism has costs, firms (hierarchies) exist as a cost saving mechanism.
|
|
TCE in IS
|
If information systems can reduce transaction costs, IS can give rise to markets rather than hierarchies. Turns out usually what emerges is hybrid forms.
|
|
Criticism to TCE
|
TCE neglects influence of prexisting relations. TCE neglects power relations between suplliers and buyers.
|
|
Key Articles, Authors STRUCTURATION
|
Giddens (founder 1974), Orlikowski and Robey (IS implementation, 1991)
|
|
Basic Idea STRUCTURATION
|
Structuration is the social progress that leads to the reciprocal interaction of actions and structures
|
|
Key Elements STRUCTURATION
|
Social systems: actions situated in social practice. Social structures: contextual rules and resources that enable interactions. Actions result from stock of knowledge, resources and norms.
|
|
STRUCTURATION in IS
|
structuration is the bridge between use and design. The artifact defines human actions and in turn is defined by the human actions.
|
|
Basic Idea CDT
|
Private opinion of the people changes to bring into consistency with the behavior the person is forced to
|
|
Factors that affect the strength of dissonance CDT
|
Number of dissonant beliefs. Importance attached to each belief
|
|
Ways to eliminate dissonance CDT
|
1- Reduce importance of beliefs, 2- add more consonant beliefs, 3- change dissonant beliefs
|
|
CDT in IS
|
IS implementation success. Reduce unrealistic expectations.
|
|
Basic Idea PT
|
How people make decisions under uncertainty and risk. Gains are more valued than losses.
|
|
Key Articles, Authors PT
|
Kahneman and Tversky (founders, 1979)
|
|
Origins PT
|
PT addresses the shortcomings of expected utility theory by explaining seemingly irrational behavior.
|
|
Value Function PT
|
Deviation from status quo concave for gains, convex for losses. Also the function is steeper in loss (loss aversion)
|
|
Weighting Function PT
|
Different weighting schemes are used when evaluating outcomes. Moderate or highly likely events are underweighted where as unlikely events are overweighted.
|
|
Framing Effect PT
|
Same problem can be framed as either a loss or a gain. This will determine the outcome.
|
|
PT in IS
|
Used in escalation of commitment to IT projects, development time, bidding on IT projects.
|
|
Origins Agency Theory
|
Agency theory originates from institutional economics.
|
|
Basic Idea Agency Theory
|
Relationship between a principal and an agent. Agency problem is that agent can act opportunistically due to (1) goal incongruence, (2) monitoring problem. Agency problem causes losses (Agency Costs: Monitoring, Bonding,Residual cost)
|
|
Agency Problem (Agency Theory)
|
The agent can act opportunistically because his goals are different from principal's and the principal can not effectively monitor the agent.
|
|
Agency Cost
|
The opportunistic behavior of the agent can create losses: Monitoring cost incurred by principal to observe the agent. Bonding cost incured by the agent to make his/her services more attractive and Residual cost: opportunity cost of not having principal do his own ****.
|
|
Agency Theory in IS
|
Software developers and deadline setting.
|
|
Agency Theory Moral Hazard
|
Due to assymetric info, the agent can act opportunistically
|
|
Agency Theory Adverse Selection
|
Due to assymetric info the market can become adverse to good agents
|
|
Agency Theory Risk Preference
|
Agent and Principal will have different risk preferences (risk averse agent is usual for low-mid level), this may lead the agent to act in ways that the principal does not approve 100%.
