Abstract This paper documents the effect of investments in Enterprise Resource Planning (ERP), Supply Chain Management (SCM), and Customer Relationship Management (CRM) systems on a firm’s long-term stock price performance and profitability measures such as return on assets and return on sales. The results are based on a sample of 186 announcements of ERP implementations, 140 SCM implementations, and 80 CRM implementations. Our analysis of the financial benefits of these implementations yields mixed results. In the case of ERP systems, we observe some evidence of improvements in profitability but not in stock returns. The results for improvements in profitability are stronger in the case of early adopters of ERP systems. On average, adopters of SCM system experience positive stock returns as well as improvements in profitability. There is no evidence of improvements in stock returns or profitability for firms that have invested in CRM. Although our results are not uniformly positive across the different enterprise systems (ES), they are encouraging in the sense that despite the high implementation costs, we do not find persistent evidence of negative performance associated with ES investments. This should help alleviate the concerns that some have expressed about the viability of ES given the highly publicized implementation problems at some firms. # 2006 Elsevier

Data Warehouse

...goals of the enterprise. The technologies and terms that comprise every major provider’s portfolio are starting to look and sound alike. New product offerings appear almost identical to existing products in the same market. The terms VPN, MPLS, convergence, the ubiquitous “IP,” service level agreements (SLA), single points of contact, managed network services, and global footprints are important in the telecommunications market, but we have heard them all before. The competitive differentiation that service providers desperately seek will not occur on this homogenous slate of technology and service offerings. Only when service providers truly understand what is happening from the customer’s perspective will real competitive differentiation take place. Providers must realize that they do not drive the networking and telecom environment; the customers’ strategic and tactical objectives drive it. If service providers wish to position at higher levels in the corporation, they must change the way they communicate. Such communication should not only show an understanding of the enterprise applications themselves but also an understanding of how the applications relate to the service providers’ product set. This paper will outline three (of the many) enterprise applications and business drivers service providers can use to differentiate themselves. We will examine the concepts of data warehousing and data mining for the purpose of effective enterprise resource planning (ERP), customer...

The Impact of Enterprise Resource

...The Impact of Enterprise Resource Planning in the Company Environment Introduction Since the Sarbanes-Oxley Act of 2002, companies are required to report effectiveness of their internal controls on purpose to reduce fraud. Enterprise Resource Planning (ERP) systems have taken advantage of this new focus on internal control because it offers an integration of an organization’s main business functions. Even though the value of ERP has been debated in trade periodicals, there is no large evidence of whether the benefits of ERP implementation exceed the costs and risks. This paper is designed to evaluate the impact of enterprise systems on a firm's environment, and how it reflects in the production and management of earnings. “The Impact of Enterprise Resource Planning (ERP) Systems on the Effectiveness of Internal Controls over Financial Reporting” by John J. Morris The study to produce the article was motivated by an empirical research question about the impact of ERP systems on internal control. Specifically, the study examined if firms that implemented ERP systems are more or less likely to report internal control weaknesses in their annual reports than firms that did not. This study used a sample of 108 firms that confirmed the execution of ERP systems between 1994 and 2003, and also an equal number of control firms, accorded by industry and size. The results show that firms that implemented ERP are less likely to report internal control weaknesses than the firms which did...

Masters Thesis in Business Administration (FED 006) Author Stephen Rupia Lyabandi Executive Summary Title: Do organizations have IT Strategies? A Study on how organizations describe their IT Strategies. Author: Stephen Rupia Lyabandi Tutor: Anders Hederstierna Problem: The research problem of this study is lack of insight on how organizations describe their IT strategies in relation to other strategies. IT strategy continues to be a major challenge for Information Technology intensive organizations and managers. Over the last two decades, the way researchers on information systems have viewed and analyzed IT strategy in organizational systems has not significantly been modified. Recent studies show that one of the main problems is that the concept of IT strategy has been around for nearly two decades and although many organizations have been using it, the meaning and reference of the idea remains elusive. Those who have attempted to define it have not reached an agreement. Purpose: The purpose of this study is to define the problem and explore whether organizations have IT strategies, and how these are describe in relation to other strategies. This research study also investigates how these organizations incorporate IT...

Erp Implementation-Procedures, Issues, Challenges & Failures

...ON ERP Implementation-Procedures, Issues, Challenges & Failures Introduction An Enterprise Resource Planning (ERP) system is an integrated computer-based application used to manage internal and external resources, including tangible assets, financial resources, materials, and human resources. Its purpose is to facilitate the flow of information between all business functions inside the boundaries of the organization and manage the connections to outside stakeholders. Built on a centralized database and normally utilizing a common computing platform, ERP systems consolidate all business operations into a uniform and enterprise-wide system environment. An ERP system can either reside on a centralized server or be distributed across modular hardware and software units that provide "services" and communicate on a local area network. The distributed design allows a business to assemble modules from different vendors without the need for the placement of multiple copies of complex and expensive computer systems in areas which will not use their full capacity. To be considered an ERP system, a software package should have the following traits: ➢ Should be integrated and operate in real time with no periodic batch updates. ➢ All applications should access one database to prevent redundant data and multiple data definitions. ➢ All modules should have the same look and feel. ➢ Users should be able to access any information in the system without...
