Existing frameworks and where they fall short.

8 Feb

During my own research on this topic I realised that there is no usable and comprehensive framework for measuring the quality of an information system available in the public domain today.  In this series of blogs I have already given my thoughts on the need for proper planning in developing new systems [1] and of the need to ensure that the end user is satisfied with the system they are using [2].

There are existing frameworks that exist to measure the quality of different processes and systems but none to measure the quality of an information system.



The above image is a framework developed to measure the quality of the library services system in Charles Surt University. This framework applies the four part quality cycle model. Plan, implement, review, improve (PIRI) . If the four part quality cycle could be developed with the aim of measuring IS quality and if user satisfaction could be integrated along with ease of use and usefulness it could form the blueprint for a framework on IS quality that could be utilised by organisations.

The cycle of change model is another model which could serve as inspiration for or be adapted to be a framework for IS quality. Like the PIRI model it goes through four phases, Plan, implement, measure and evaluate. These four phases could realistically be adapted to measure the quality of an IT system. If it was possible perceived ease of use could be measured during the planning stage and perceived usefulness could be measured during the implementation stage through testing and examination of the system with the intended users. If it was possible for user satisfaction to be measured in the third stage then it would be a comprehensive framework for measuring the quality of an IS system. However, this is all merely speculation as this all requires exact and concise measurement of ease of use, usefulness and user satisfaction which, as has been mentioned previously, are all extremely difficult to calculate.



In order for us to go forward and develop a framework for the measurement of IS quality we will need to examine what has been done before us, mistakes that were made and areas that we can improve on. If we do this correctly then we will be able to create a new framework which will incorporate all the areas we have examined already and give management teams a tool to enable them to get the most out of their information systems.
