Integrated Success Model (ISM).

1 Feb

An integrated success model (ISM) can be another model used for evaluating IS success. Within the article “An Integrated Success Model for Evaluating Information System in Public Sectors,” by Abdel Nasser H. Zaied, an integrated model for evaluating IS success was studied. This model was created within accordance of the Technology Acceptance Model (TAM) and DeLone and McLean (D & M) updated model.[1] As the D&M model has been explained in many of the previous blogs by mcoconnell[2] and lucid21[3], I will provide a short explanation of the D&M model and then will provide a description of the TAM model.

The DeLone and McLean model of IS success, was originally created in 1992 and was then updated in 2003. The updated version included the following dimensions of IS success: Systems quality, Information quality, Service quality, Use, User satisfaction, and Net benefits. [1]

In 1985, the TAM was introduced by Fred Davis within his thesis at the MIT Sloan School of Management.[4] This model is used for representing user acceptance of information systems. This model begins by suggesting external variables as the foundation for outlining the impact of external factors on two internal beliefs. These beliefs influence users approach toward the IS usage. The outlook towards the usage of IS, has impacted on behaviour intention to use. [1] This model is shown in figure 1 below.

Within the article, an integrated model for evaluating IS success was created. This model was created in accordance with the TAM and D&M updated model. Within this model, ten different dimensions for measuring IS success were established. These dimensions were: Information quality, Behaviour intention, Perceived ease of use, Management support, Perceived usefulness, system quality, Service quality, User satisfaction, Training and finally User involvement. This integrated model for evaluating IS success considers that the information quality, service quality and system quality are associated to management support, training and user involvement. These then influence perceived ease of use and usefulness which then have an effect on user satisfaction and behaviour intention. This model is shown in figure 2 below. [1]
