The document discusses three models of information system success: 1) The DeLone & McLean Model from 1992 which synthesizes six factors of IS success including system quality, information quality, use, user satisfaction, individual impact, and organizational impact. 2) The Seddon Model from 1997 which focuses on the interrelationships among measures of information and system quality, IS use, and the benefits of IS use. 3) The Organizational Transformation Model which captures the organizational change dimension of successful IS implementation through its examination of system and information quality, organizational IS use, and organizational transformation due to IS.

Constructed by DeLone and McLean in

Considered to be the pioneer in the
information system field
Overcomes the short-comings of the
Technology Acceptance Model (TAM)
Synthesizes a six-factor taxonomy of IS
success such as:
Systems Quality
Information Quality
IS use
User satisfaction
Individual impact and
Organizational impact

Seddon proposed this model in 1997
Model focuses on the variance aspects of the
interrelationships among the taxonomic
categories
Considers three classes of interrelated
variables:
Measures of Information and System
Quality
General measures of net benefits of IS use
Behaviour with respect to IS use

6. Expectations

future IS use

9. Change Management
 Role mapping
 Overall & change specific communication
 Overall & change specific training

Change Management is an
organized, systematic application of the
knowledge, tools, and resources of change that
provides organizations with a key process to
achieve their business strategy
Change management
plans, initiates, realizes, controls, and finally
stabilizes change processes on both, corporate
and personal levels

11. 



First effects of change on
employees, leaders, and on performance levels
are negative
These effects include fears, stress, frustration
and denial of change
Most employees tend to react with resistance to
change rather than seeing change as a chance to
initiate improvements
They are afraid of losing something, because
they have incomplete information on how the
change processes will effect their personal
situation in terms of tasks, workload, or
responsibilities
