“…When opting to upgrade, the performance and input/ output capacity of the existing hardware and supporting systems must be measured (Whang et al, 2003). Estimating the degree of modifications and corresponding implications, enables decision makers to better understand the benefits and trade-offs required (Parthasarathy and Daneva, 2016). Dor et al (2008) automated this process using an algorithm that evaluates the impact of the new version features on the implemented version and estimates the effort required to upgrade.…”

Purpose-Enterprise Systems (ES) upgrade is fundamental to maintaining a system's continuous improvement and stability. However, whilst the extant literature is replete with research on ES upgrade decision-making, there is scant knowledge about how different decision processes facilitate this decision to upgrade. This paper aims to investigate and better understand these processes from an organisation perspective. Research approach-A qualitative survey design adopted, utilised a web-based questionnaire and semi-structured interviews to collect data from 23 large organisations. Data accrued was qualitatively analysed and manually coded to identify the various decision processes undertaken during ES upgrade decisions. Findings-Analysis results reveal complex interrelations between the upgrade drivers, the need to evaluate the new version's functionality and the upgrade impact. Understanding the interaction between these elements influences the upgrade decision process. Research limitations-The study proposes ES upgrade processes that support a decision to upgrade major releases. Further research is required to offer either similar or conflicting arguments on the upgrade decision-making and provide a probabilistic generalisation of the decision-making processes. Originality-The research offers a comprehensive and empirically supported methodical approach that embraces an evaluation of a new version's functionality, technical requirements and concomitant upgrade implications as intrinsic decision processes. This approach assists in the decisions to establish the upgrade need and determine the level of change, effort required, impacts and associated benefits.

“…Hakim, A. and Hakim, H. (2010) proposed a method for selecting a suitable ERP system that can reflect the purpose of the introduction, as well as the strategies of the company, effect of the introduction, risk factors, technical feasibility, and internal requirements. Ibrahim et al (2018) and Parthasarathy and Daneva (2016) analyzed a priority of collected requirements and proposed a decision model of a level and method of customization. In addition, for customization, Parthasarathy and Sharma (2017) analyzed the effect of ERP customization on software quality.…”

This paper presents a method for analyzing the effect of implementing an enterprise system (ES) in the construction industry during the ES introduction and planning stages. The effect is a reduction in employees’ work time. The proposed method is based on the 1) level of digitalized and automated activities, the 2) complexity of the activities, and the 3) complexity of the processes in the workflow. The method was applied at a construction company that has no enterprise resource planning (ERP), and the method’s accuracy was evaluated by information technology consultants who have performed planning, construction, and operation in relation to ERP. The result shows that the effect of management business was the largest; most of this effect was on data management and review. After users became familiar with ERP, the reduction in data input time increased. The analysis method takes less time and costs less than using surveys to measure the work time and satisfaction of ES users. It can also identify processes in which the effect increases or decreases, thereby guiding any modifications of the ES before it is introduced.

“…Service-oriented approaches as indicated in [29] assume bottom-up thinking where the ERP system is segmented in provisions of business processes or business scenario models; various technical complexions are quantified to help solve the ERP customization estimation problem. They focus on the analytical level of a business process or a scenario model and proceed with delivering estimation figures at that level.…”

Enterprise resource planning (ERP) systems are large, modular enterprise applications designed for most of the company’s business processes. They include a range of different forecasting methods. The paper analyses the existing forecasting methods in ERP systems and provides a comparison of forecasting methods in ERP systems. It considers the problem of prediction integration in ERP systems and describes the general process by a conceptual model based on academic literature from forecasting with ERP systems. The study provides an integration approach, which is the most suitable one for providing forecasting functions in ERP systems.
