The purpose of this paper is to identify the existence of studies, by exploring the current literatures, on interaction among actors in Enterprise Resource Planning (ERP) implementation.

A new classification framework is offered, along with the two dimensions of ERP implementation: determinants and outcomes, to provide four types of research classes. Hundreds of articles were searched by using keywords from journal data bases. The selected articles were grouped based on the new classification of ERP implementation, followed by an in-depth analysis by using the Context, Intervention, Mechanism, Outcomes logic and the system of systems methodologies (SOSM) framework.

The interactions among actors in ERP implementation have been overlooked, although there is almost always disagreements, misperceptions, and conflicts. Managing the interactions among actors is considered important because common failures in ERP implementation are often caused by mismanaged interactions among the key actors. Unfortunately, the existing research has so far shown a small effort to study how the actors’ interactions are managed.

One key limitation of this research is that the number of actor-related articles is lesser than the factor-related articles. Further research should be conducted to explain how to manage the interactions among the actors in each stage of ERP implementation.

A guidance to prepare the entire organization prior to the ERP implementation to seriously consider the typical conflict among actors on each stage of ERP implementation and its causal factors and how to resolve them.

The importance of understanding typical conflict among actors, its causal factors, and how to resolve them can be extended to other projects or social phenomenon.

This proposed framework is new to the ERP literature and serves to identify and expand further research on actors’ interactions to improve the success of ERP implementation. This is the first research to identify the interactions among actors in ERP implementation by using a clearly structured methodological approach, which is conducted by critically reviewing the ERP implementation literature.

The detrimental impact of data breaches on organizations and their customers has been well documented in the literature. These breaches expose sensitive information, raising concerns about reputational damage and substantial financial losses for affected firms. Prior research has consistently demonstrated the significant financial repercussions of data breach disclosures, with a significant decline in the market value of breached firms following the incident’s revelation. However, recent literature has documented the shift in consumer perception toward data breaches, warranting a revisit of this important and relevant issue with more recent data. This study aims to revisit the cost of data breach disclosures by empirically analyzing the impact of recent data breach incidents on the market value of affected firms.

The authors collect the data regarding data breach incidents among publicly traded companies in the USA listed in the S&P 500 index from 2013 to 2021. The empirical analysis relies on the event study approach, and the market value of each firm is estimated using the Fama-French three-factor model.

This study finds that the negative market reaction to data breach announcements in recent years has been significantly weaker than those reported in prior works from the past decade. This result confirms the shift in consumer perception toward data breaches in the market.

While prior research has quantified the cost of data breach disclosures, the authors posit that a renewed examination is essential within the contemporary digital environment. Consumer behavior and market sentiment have undergone significant transformations in recent years, necessitating a revisit of this important issue with updated data. This study not only documents this evolving phenomenon but also yields crucial policy recommendations. Notably, it challenges the conventional wisdom to rely on market forces as an adequate deterrent against data breaches. Consequently, updated regulations may be necessary to effectively navigate the complexities of the evolving digital landscape.
