Process Mining-Driven Optimization of a Consumer Loan Approvals Process The BPIC 2012 Challenge
Outline 1、Introduction 2、Materials and Methods 3、Understanding the Process in Detail 4、Assessing Process Performance 5、Discussion 6、Conclusions 7、Homework
Introduction • In BPIC 2012 on the loan and overdraft approvals process of a real-world financial institution in the Netherlands. • Attempted to investigate following areas in detail: • Develop thorough understanding of the data • Develop a detailed understanding of the underlying process • Understand critical activities and decision points • Understand and map life cycle of a loan application from start to eventual disposition as approved, declined or cancelled • Identify any resource level differences in performance one can discern based on available data • Identify opportunities for “process interventions”:places in the process based on likelihood of success
Materials and Methods • The data captures process events for 13,087 loan / overdraft applications over a roughly six month period from October 2011 to March 2012. • The event log is comprised of a total of 262,200 events within these 13,087 cases. • Starting with a customer submitting an application and ending with eventual conclusion of that application into an Approval, Cancellation or Rejection(Delined).
Log Description • An application is submitted through a webpage. Then, some automatic checks are performed, after which the application is complemented with additional information. • This information is obtained trough contacting the customer by phone. If an applicant is eligible, an offer is sent to the client by mail. • After this offer is received back, it is assessed. When it is incomplete, missing information is added by again contacting the customer. • Then a final assessment is done, after which the application is approved and activated.
Tools used for analysis • Disco • Preprocessing and exportation of data into formats suitable for Microsoft Excel analysis. • Microsoft Excel • Used Excel alongside Disco, which helped us visualize, rationalize and refine observations in real time. • CART Implementation from Salford Systems • Conducting preliminary segmentation analysis of the loan applications to assess opportunities for prioritizing work effort.

Discussion • Managing Event Complexity in Data • The event log would also benefit from consolidation of events that happen concurrently, such as those that occur when successful applications are approved (A_APPROVED, A_REGISTERED and A_ACTIVATED).
Conclusions • More extensive work in this area would be greatly aided by the inclusion of additional data points, such as customer information, policies that govern the process, operating costs for the process and eventual customer value. • The bank would find significant additional benefits from exploring such additional areas, for example , social network analysis.
Homework • 使用本篇銀行log檔,依照您的觀點,提出”簡化流程”的方法。 • 將簡化後的流程結果,匯出JPG及轉存成CSV檔。 • 繳交信箱:engineer0710@gmail.com • 繳交日期:2013/11/15(五)
