“…Previous studies identified factors that may affect maintenance cost (Buchmann et al 2011;Correa et al 2016;Li et al 2010;Nguyen et al 2011;Ren et al 2011a;Tsu-noda et al 2015) and provided methods to estimate the development cost of software (April 2010;Matijevic et al 2012;Ng, Gable 2010;Ren et al 2011b;Salmeron, Lopez 2012;Sarno et al 2015). Several previous studies have proposed a method for the successful implementation of an ES, though these are not directly related to maintenance (Hadidi et al 2017;Niu et al 2013Niu et al , 2014Soja et al 2015;Wu et al 2009;Xu 2011).…”

“…Among the previous studies that have analyzed influence factors on maintenance costs, Buchmann et al (2011) proposed a method to estimate realistic maintenance costs based on less effort and cost required using a multilevel approach. Correa et al (2016) derived the factors related to maintenance and supporting costs. Li et al (2010) analyzed influence factors on corrective maintenance activities and described and analyzed the defect type that causes high maintenance costs based on interviews with IT system developers.…”

A construction company without a similar information technology (IT) system in the past has insufficient historical data to use for investment decision-making of IT system. An estimation of maintenance costs is especially more uncertain than the initial investment costs, and the uncertainty is greater when the IT system is used over a long period, such as an enterprise system (ES). This study proposes estimation criteria for the maintenance costs of an ES for an accurate investment decision. First, the causes of maintenance are determined, and the level of maintenance analyzed. Then, the result is compared with a general trend of maintenance incidence (bathtub curve) that is widely used as reference criteria to estimate maintenance cost. The level of maintenance was high during the early stage but steadily decreased in the middle and end stage because high-cost maintenance activities were postponed with the approach of the time in which the ES was being restructured. This trend is different from the bathtub curve that increases again during the end stage. Thus, when a maintenance contract is negotiated, the maintenance level that affects maintenance cost should be considered as well as the incidence of maintenance.

BACKGROUND: There is a growing number of reasons that encourage worldwide universities to implement integrated systems and further introduce major technology-enabled change in the organization. Successfully implementing and sustaining such change demands an effective post-implementation strategy on the part of top management. OBJECTIVE: The purpose of this research work is to review the post-implementation strategical aspects of integrated information systems projects of academic organizations. METHOD: For this purpose, an exploratory case study is conducted in one of the leading universities in Pakistan. This institution implemented enterprise information systems recently in 2021. The interviews of the officers involved in the process of implementation and management of such systems were conducted and transcribed. CONCLUSION: The findings of this research will help the top management to proactively develop effective strategies for the successful implementation and maintenance of enterprise information system projects in the organization.
