From IS Quality to IS Success?

4 Feb

Information Quality is said to have more of an impact on the outcome of success. It is becoming increasingly more important in order to achieve well in business today. The higher the quality for the user, the more success the user will have in utilizing information systems. For this blog I hope to explain the role of quality in information systems and indeed how the two are inextricably linked to the outcome of a business and indeed its overall success.

“Information system quality is expected to have a strong impact on information system  effectiveness, which can be defined as the degree to which the information system meets its intended purpose. With proper business/IT alignment, an effective information system is an information system that successfully plays a central role in the fulfillment of strategic business goals like cost leadership, increased profitability or sustained growth” Poels & Si-Saïd Cherfi (2006)

In this blog I will provide a framework as well to show the importance of IS quality and IS Success. The model that I am using is the DeLone and McLean (D&M) Model of IS. I think this framework shows the relationship between Quality and success.



“According to the D&M Model, information system quality affects both the use of the information system (i.e. whether the information system is adopted by its intended users) and how satisfied the intended users are with this use. Following the causal chain, use and user satisfaction are direct antecedents of the information system’s impact on individual users (e.g. in terms of improved task performance). Finally, it is through these impacts on the individuals of the organization that the information system eventually has an organizational impact (e.g. reduction of operational costs, shorter time to market)” Poels & Si-Saïd Cherfi (2006)

It shows the difference between the dimensions of information system quality:  information quality and system quality. “The former construct is concerned with the quality of the information that the information system delivers to its users and is measured in terms of accuracy, completeness, currency and format, whereas the latter construct relates to the quality of the system that produces the information output, which can be expressed in terms of accessibility, reliability, flexibility, integration and response time and has also often been measured as the ease of use or user friendliness of the system”

Overall I think that this framework is a good starting point for a business to develop there IS Quality. It does distinguish between information quality and system quality which I think is important. With frameworks though, there is no one answer for everyone. It must be adapted and tinkered with in order to suit each type of business. I think this is a start but must be adapted.
