Eat, sleep, repeat

Now the subjects were also asked to record other activities: washing, sleeping, watching tv, etc. These can be found in the dataset daily_activities.

Use the three available performance metrics to solve the questions below.

processing_time() measures the time a person is active
idle_time() measures the time a person is idle
throughput_time() measures the total time between first and last reported event

Exercise instructions

Which of the activities uses the most time? And which the least? Show graphically after using the processing time metric.
What is the average duration (in hours) on which data is reported, i.e. from the first activity a person executes until the last activity of that person?
Not all subjects recorded their activities continuously. What is the amount of time per subject (on average, in hours) of which the activities were idle?

The amount of event data has grown enormously during the last decades. A considerable amount of this data is recorded within the context of various business process. In this chapter, you will discover a methodology for analyzing process data, consisting of three stages: extraction, processing and analysis. You will have our first encounter with the specific elements of process data which are required for analysis, and have a first deep dive into the world of activities and traces, which will allow you to reveal of first glimpse of the process.

Exercise 1: Introduction to process analytics Exercise 2: Identify process elements Exercise 3: Process Analysis Workflow Exercise 4: Activities as cornerstones of processes Exercise 5: Retrieve basic process information Exercise 6: Explore activities Exercise 7: The happy path Exercise 8: Create process maps Exercise 9: Components of process data Exercise 10: Event data identifiers Exercise 11: Constructing event data objects Exercise 12: Inspecting event data objects

A process can be looked at from different angles: the control-flow, the performance and the organizational background. In this chapter, you will make a deep dive into each of these perspectives. The control-flow refers to the different ways in which the process can be executed, and thus, how it is structured. Considering performance, we are both interested in discovering how long things take, as well as when they take place. Finally, the organizational perspective looks at the actors in the process.

Event data rarely comes in a form which is ready to analyze. Therefore, you often require a set of tools to get the data in the right shape, before we can answer our research question. At the end of this chapter, you will be familiar with three common preprocessing tasks: filtering data, aggregating events and enriching data.

Exercise 1: Filtering cases Exercise 2: The path well traveled Exercise 3: The downside of rejections Exercise 4: The downside of refusals Exercise 5: Filtering events Exercise 6: The vicious disapproval circle Exercise 7: Working with high-paid R&D candidates Exercise 8: Aggreggating events Exercise 9: Disapprovals are disapprovals Exercise 10: Zooming out Exercise 11: Admiring the view Exercise 12: Enriching events Exercise 13: Everything has a cost Exercise 14: Cost versus urgency

In this final chapter we will use everything we have learned so far to do and end-to-end analysis of an order-to-cash process. Firstly, we will transform data from various sources to an event log. Secondly, we will have a helicopter view of the process, exploring the dimensions of the data and the different activities, stages and flows in the process. Finally, we will combine preprocessing and analysis tools to formulate an answer to several research questions.
