This is a compendium of three studies: Literature Study, Internet Commerce Evaluation Scale (ICES) Study, and Convenience Study. Each study answers one of the research questions. The Literature Study summarizes the available research literature of features of successful I-commerce sites. The literature review was split between empirical and subjective studies and content analysis was used to organize features into 12 properties. The properties were rank based on the number of times the features for that property were mentioned in the literature review. The results indicated the authors of empirical and subjective studies were in agreement as to the ranking of the properties of a successful I-commerce website. Based on the results of the Literature Study, the ICES was designed for the ICES Study and presented to five experts in the field of web design and used to evaluate six websites. The ICES was divided into two sections, Checklist of Features and Rating Scale. Scores were obtained for each section plus a total score, compared using Pearson's correlation coefficient, and each resulted in high correlations. Normative data for frequencies was obtained and split-half reliability was used to obtain internal consistency, which resulted in high reliability. The checklist score was an analytical score whereas the rating score was subjective. All of the scores on the ICES were significantly related to the validity criterion total satisfaction. The Convenience Study subjects the theory of web convenience to empirical testing. The theory predicted that as convenience increases (at least from low to high), (1) time used to complete the purchase decreases, and (2) satisfaction increases. Six websites were selected and given to participants selected from students enrolled in summer businesses classes at three institutions of higher learning in two western states. Each participant viewed a website, attempted to locate and purchase a product, completed the Site Review Protocol questionnaire involving the two dependent variables (time used to complete the purchase and total satisfaction) and completed the ICES. MANOVA and ANOVA were used and a significant level of convenience obtained as related to the dependent variables. Hence, the theory of web convenience was confirmed.
