Abstract

Enterprise Resource Planning (ERP) systems are large scale integrated systems covering most of the business processes of an enterprise. ERP projects differ from software projects with customization, modification, integration and data conversion phases. Most of the time effort and time estimations are performed in an ad-hoc fashion in ERP projects and as a result they frequently suffer from time and budget overruns. Although there is no consensus on a methodology to estimate size, effort and cost of ERP projects there are various research studies in the field. The purpose of this paper is to review the literature on effort estimation methods for ERP projects, their validations and limitations. The systematic literature review used online journal indexes between January 2000 and December 2016. Studies focusing on effort estimation for ERP projects were selected. Two reviewers assessed all studies and 41 were shortlisted. In most of the studies, cost factors for ERP projects were investigated and validated. Our findings showed that effort estimation methods have mostly used function points as an input. Validations of these methods were mostly done by using history-based validation approaches.
ERP项目的工作量估算-系统回顾
企业资源规划(ERP)系统是覆盖企业大部分业务流程的大型集成系统。ERP项目不同于软件项目,有定制、修改、集成和数据转换阶段。在ERP项目中,大多数时间工作和时间估计都是以一种特别的方式执行的,因此它们经常遭受时间和预算超支的困扰。虽然在评估ERP项目的规模、工作量和成本的方法上没有达成共识,但在这个领域有各种各样的研究。本文的目的是回顾ERP项目的工作量估算方法的文献,它们的有效性和局限性。系统文献综述采用2000年1月至2016年12月的在线期刊索引。本文选取了ERP项目工作量估算方面的研究成果。两位审稿人评估了所有研究,41项入围。在大多数研究中,对ERP项目的成本因素进行了调查和验证。我们的发现表明,工作量估算方法大多使用功能点作为输入。这些方法的验证主要是通过使用基于历史的验证方法完成的。
