Outline

Business Process Modeling (BPM) Process model quality

“what is a good process model?” Process of process modeling (PPM)

“how to make a good process model?”Visualizing the PPM with PPMChartsObservations, hypotheses, future work

Structured Process Modeling (SPM)



Business Process Modeling (BPM)

Business process model in BPMN notation



Process model quality

Poor model quality Many errors Many nodes Many crossing arcs Many nested gateways …

Strong model quality Few errors Few nodes Few crossing arcs Few nested gateways …

Correctness

Understandability

Maintainability



Process of Process Modeling (PPM)

Properties of textual description

Properties of modeler

Properties of modeling process

Properties of resulting model

PRIMARY RESEARCH FOCUSProperties of real process

Properties of observation process

Properties of softwareand modeling language




Observational modeling sessions People construct models Every action on modeling canvas is logged Modeler information is collected through survey Different datasets

• 120 students in Eindhoven 2010• 14 experts in Berlin 2010• 14 experts in Eindhoven 2011• 118 students in Eindhoven 2012




Properties of the modeling processActivity Timestamp Attributes

Create start event 10:00 Id = 1; x = 10; y = 10

Create activity 10:04 Id = 2; x = 40; y = 10; name = “Receive order”

Create edge 10:05 Id = 3; from = 1, to = 2

Move activity 10:07 Id = 2; x = 15; y = 10

Create gateway 10:08 Id = 4; x = 65; y = 10; type = “XOR”

Create edge 10:09 Id = 5; from = 2, to = 4

Create activity 10:24 Id = 6; x = 80; y = 0; name = “Reject order”

Create activity 10:25 Id = 7; x = 80; y = 20; name = “Prepare order”

Create gateway 10:27 Id = 8; x = 105; y = 10; type = “XOR”

Cognitive aspects Cognitive Load Theory (CLT)

limited capacity of working memory

Cognitive Fit Theory (CFT)effect increase if task representation fits




Previous research Process mining research: merging event logs Recently changed scope of PhD research after promising

results of explorative research described in this presentation




Future research: Structured Process Modeling Literature review: cognition, problem solving, coding

principles, process model quality, visualization Theory development: structured process modeling,

causality relation with model quality, confounding variables (modeler, tool, model language, case, …)

Tool support: syntax highlighting, error indication/correction, structured modeling, …
