Information system is important to be applied in enterprise system by giving
contribution to productivity, quality, and organization competitiveness, especially
for Small Scale Medium Enterprises (SMEs), somehow SMEs face some
inaccurate data process. In fact, information system success is influenced by many
criteria, however there is no finding evaluates criteria correlations. Through
information system success model, correlations among criteria can be determined.
Therefore, evaluation of information system implementation is important, so that
SMEs know how to effectively implement good information system. Information
system success model of Sinaga et.al is a new information system model adopting
Gable, et.al model and Delone and McLean which have been widely known.
This research adopts information success model of Sinaga, et.al, Gable, et.al, and
Pratama. It is conducted by interviewing and observing several Small Scale
Medium Enterprises (SMEs) which manually organize the information system in
Yogyakarta. First observation is proposed to know criteria correlation impacts by
using Decision Making Trial and Evaluation (DEMATEL). The second observation
is proposed to evaluate whetherSMEs which manually organize information
system needs information technology (IT) improvement or not to overcome
information problems they face by using Analytical Network Process (ANP).
The research results correlations and priority of IT needs. Furthermore, ANP
synthesis shows that the weight of IT’s need improvement is 60.7% while the
remaining 39.3% denotes SMEs do not need IT improvement. The ANP priority
also shows the weight of information system implementation on Finance,
Marketing, and Production is 39.1%, 37%, and 23.9% respectively. Moreover
criteria of Ease of Use becomes the most important criteria to be concerned.
