Business is a war to get the attention you deserve from your enemies, and many competitors strive to gain a prominent position. Organizations are constantly seeking innovative ways to work to stay in a competitive business environment. Business process reengineering (BPR) is one of the most management approaches that are adopted by many organizations in order to achieve a dramatic increase in performance and cost reduction. Since the risks enfolded and failure rates related to BPR projects are very high, it is necessary to find ways to support success of BPR in a systematic approach. The major target of this article is to find the implementation of the proposed model to reengineer business processes (BPs) successfully via integrating critical success factors (CSFs) of BPR and BPs' performance. It is created to detect the inefficiencies and bottlenecks in the business process, decrease costs, time and increase quality of business processes, enhance financial environment and make an effective and efficient performance of the business process. It also applies a mining technique of association rule to examine the link between CSFs and several BPs and measures business processes' performance (intended BPR success) by process time, cycle time, quality and cost pre and post reengineering BPs. Thus, it uses a way to select the appropriate model for each business process. The proposed model will be implemented using a real world the Egyptian tax authority case study in order to prove its usefulness and efficiency. Then, inferred CSFs were applied according to each process, which proved the validity and success of the proposed model.

商业是一场从敌人那里获得应得关注的战争，许多竞争对手都力争获得显着的地位。组织不断寻求创新的工作方式，以保持竞争激烈的商业环境。业务流程重组（BPR）是许多组织为了实现性能大幅提高和成本降低而采用的最广泛的管理方法之一。由于 BPR 项目所涉及的风险和失败率非常高，因此有必要找到系统方法来支持 BPR 成功的方法。本文的主要目标是找到所提出的模型的实现，通过整合 BPR 的关键成功因素 (CSF) 和 BP 的绩效来成功地重新设计业务流程 (BP)。它的创建是为了检测业务流程中的低效率和瓶颈，减少成本、时间并提高业务流程的质量，改善财务环境并有效且高效地执行业务流程。它还应用关联规则挖掘技术来检查 CSF 和多个 BP 之间的联系，并通过流程时间、周期时间、质量和成本重新设计 BP 前后来衡量业务流程的性能（预期的 BPR 成功）。因此，它使用一种方法为每个业务流程选择适当的模型。所提出的模型将使用现实世界中的埃及税务机关案例研究来实施，以证明其有用性和效率。然后，根据每个流程应用推断的CSF，证明了所提出模型的有效性和成功。
