Disco Analysis for Process Mining Comparing Process Models and Investigating Case Variants

Assignment Task

Part A  - Disco Analysis 

You are to use an event log. It is a real-life event log publicly available for process mining analysis. Unless otherwise specified, the complete, unfiltered, original log should be used to answer each of the three questions using the Disco software.

1. Analyse and interpret the following process models generated by Disco.

a. Compare and contrast two process models (maps) – one generated using the setting: 100?tivity and 100% paths and the other generated using the setting 50?tivity and 25% paths. Explain why we should not use a model with 0% paths to understand process behaviours.

b. Investigate the case variants detected from the log. Overall, how many case variants are present in the log? Report on the top five (5) most frequent case variants and their respective frequencies. How much of the log do these five (5) case variants cover? Investigate the variants with low frequencies. How many variants only have less than 10 cases? Explain the implications of a high number of case variants when you try to generate a representative process model.

2. Compare their process behaviours (i.e., Are the two process models quite similar or very different? Observe the activities/paths/rework loops etc) and performance (i.e., throughput times, cases, bottlenecks) of two groups of cases. Describe your observations.

a. Group A: Cases for Car Loans.

b. Group B: Cases for Home Improvements.
