  • ERP´S Implementation Methodologies Review
    R M B www.irmbrjournal.com September 2017 R International Review of Management and Business Research Vol. 6 Issue.3 I ERP´s Implementation Methodologies Review MARÍA DEL CARMEN GUTIÉRREZ-DIEZ Universidad Autónoma de Chihuahua Email: [email protected] Tel: +116144251083 LAURA CRISTINA PIÑÓN-HOWLET Universidad Autónoma de Chihuahua Email: [email protected] Tel: +116141691623 ALMA LILIA SAPIÉN-AGUILAR Universidad Autónoma de Chihuahua Email: [email protected] Tel: +116144420040 IRMA LETICIA CHAVEZ MARQUEZ Universidad Autónoma de Chihuahua Email: [email protected] Tel: +116144420040 Abstract In the 1990s, Enterprise Resource Planning (ERP) systems were the pioneers in business process management, by replacing legacy systems which became obsolete. These first implementations faced countless problems, but mainly, the lack of experience of all the parties involved. Quite a few of these experiences and difficulties have been documented over the years; But, all this literature being very different from each other, makes it difficult to unify criteria. However, some have proposed an integrative methodology from the study of the published literature. This research develops the descriptive-comparative analysis between the integration approach and the methodologies used in practice, such as the ones used by consulting firms like: Ernst & Young and Deloitte; ERP development firms: SAP and Oracle, as well as OpenERP and OpenBravo, from the open software community. The results point to Deloitte's proposal as the most complete, although the majority of these methodologies neglect the tactical aspect of such implementations. Key Words: ERP, Implementation, Methodologies, Open Source Software, Integrative Approach, Development Firms ERP Methodologies, Consulting Firms Erp Methodologies. Introduction In the 1990s, Enterprise Resource Planning (ERP) systems pioneered business process management by replacing legacy systems that became obsolete.

  • A Method to Leverage Legacy Oracle Forms Applications in an SOA
    A method to leverage legacy Oracle Forms applications in an SOA Jeroen Versteeg BSc June 17, 2008 Master thesis J. Versteeg Bsc A method to leverage legacy Oracle Forms applications in an SOA NAME Jeroen Versteeg STUDENT NUMBER 0015768 PLACE AND DATE Utrecht, June 17, 2008 INSTITUTE University of Twente, Enschede, The Netherlands FACULTY School of Management and Governance (SMG) PROGRAMME Business Information Technology (MBI) COMPANY Oracle Nederland B.V., De Meern COMMITTEE dr. M.L. Ponisio 1st university supervisor Electrical Engineering, Mathematics and Computer Science (EEMCS) dr. M.E. Iacob 2nd university supervisor School of Management and Governance (SMG) J.W. Sieben MBA 1st company supervisor Consulting Manager, Oracle Consulting A method to leverage legacy Oracle Forms applications in an SOA Summary In the last couple of years, Service Orientated Architecture (SOA) has gained a lot of momentum as a promising concept for IT systems. Vendors and organizations are adopting this technology in hope of creating more flexible and maintainable IT systems. While SOA looks like a very desirable architecture, most organizations do not start with a clean slate, but instead have made large investments in older technology, which usually does not integrate well with SOA. Many of these organizations face a dilemma with respect to the choice between keeping these outdated systems or replacing them with something new. According to market research, thousands of organizations are facing this problem with respect to applications that have been developed using the Oracle Forms application development framework. Now that Oracle is adopting SOA for new products (and newer version of existing products), customers feel pressure to adopt SOA, and need to decide what to do with existing Forms applications.

  • Compressing Effort and Schedule in ERP Implementations with Iterative Methodologies : Few Industrial Cases
    International Journal of Innovative Technology and Exploring Engineering (IJITEE) ISSN: 2278-3075, Volume-9 Issue-5, March 2020 Compressing Effort and Schedule in ERP Implementations with Iterative Methodologies : Few Industrial Cases Sunil Kaushik, Akashdeep Bhardwaj Abstract: Tough competition in the Enterprise Resource Planning or the ERP marketplace has led to the need for optimizing resources to improve productivity, cost effectiveness and smooth operations to provide immediate support and response. This ensures the customers are kept satisfied. Selecting an ERP solution that can satisfy specific business requirements enable smooth implementation. However, ERP failures indicate that 1/3 of the companies fail to realize even half the benefits of an ERP, while 3/4 implementations over run the allocated budget and 1/2 end up exceeding the planned and scheduled duration. This research focuses on Agile Methodologies and Lean Thinking. The authors implemented effort and schedule comparison their research that prove and outshines the traditional ERP implementation methodologies. Figure 1: ERP Failure Report Keywords : About Agile Methodologies, Effort Compression, ERPs are complex software systems or applications and Lean Thinking , Schedule compression. they encompass various dimensions of the organization [4,24.25]. Benefitting every part of the organization is central I. INTRODUCTION idea of any ERP implementation. Thus, ERP implementation ERP failure report by Panorama Consulting suggests that is a difficult task because of the constraints involved ERP systems have low success rates and they fail to deliver up [20,10,11,15,18]. ERP Implementations are different from to the expected benchmark. The reason behind the ERP software development because both differ in the way they are failures is attributed to technological failure, created [17,12].
