Abstract:

Maintenance cost of information system (IS) is the key to effective pricing of IS maintenance, and the complexity of information system is one of the key factors that influence IS maintenance cost. Most of previous studies pay attentions to IS complexity in the development stage, but ignore it in the operation stage. To understand the effect of IS complexity on IS maintenance cost, this paper develops a multi-stage model, which links the processes of system development, system operation and system maintenance, to comprehensively examine the effects of IS complexity on IS maintenance cost. The empirical analysis is conducted by using the real data of 162 subsystems from 7 firms. The results indicate that data model, data operation intensity and data volume have a positive effect on maintenance cost, However, data operation scope is insignificantly associated with IS maintenance cost.

Key words: information system, data complexity, maintenance cost, maintenance price
