Websites are increasingly becoming the defactor media of transmission of information and or provisioning of government services to the citizens. Accordingly, there has been an equally corresponding demand for standardization in terms of quality, productivity and efficiency. These standards are translated into several constructs or indices. Indices such as Openness, Usability, Accessibility, Transparency, Functionality, Citizen Participation etc are used to measure and standardize these websites. A key index that is continuously demanded by citizens is Transparency. Consequently, this paper proposes an approach towards the quantitative evaluation of the quality of Transparency of eGovernment websites. The approach involved the systematic appraisal of available literature to identify the key constructs that define Transparency and corresponding dimensions. Information, Reachability, Accountability and Reliability were the identified constructs of Transparency. A metric scale of measure of each construct was created. An adapted WebQEM methodology was utilized for the aggregation. A variant of Simple Multi-Attribute Rating Technique was developed and used to determine the different weights of the multi-attributes of each construct. A direct ranking technique was proposed for ranking of multiple websites. The methodology was used to calculate the Transparency of 23 Nigerian Government Ministries Websites. From the evaluation, the Federal Ministry Health was adjudged to be the most Transparent, followed by the Federal Ministry of Information and Culture and subsequently by the Ministry of Foreign Affairs. The Federal Ministry of the Capital Territory is the least Transparent.
