[This document is an exact copy of the questionnaire that subjects followed in the BPMN 2 Choreography evaluation.
However, in this copy, no page breaks between questions are introduced to achieve a better readability]

We firstly have to precise that in this questionnaire, there are no "good" and "bad" answers. We just try to take into account your opinion to develop our work.

Practices Questionnaire

Before starting with the exercises, we would like to know a little bit about your habits/practices in business process modeling. These practices will not be necessary to answer to the questions, but we want to know about them.

Do you use design techniques for software development in general? Example: UML, Flow Charts, Diagrams, ... *

Never

Very Often

As part of your profession, do you often define business processes? Example: BPMN, Aris process models, Activity Diagrams ... *

Never

Very Often

Are you used to define technical services? Exemple: with WSDL, OSGi, UPnP... *

Never

Very Often

Are you familiar with the term "Service Choreograhy"? *

Not at all

Sure

Little Introduction - Choreography

BPMN 2.0 is a modeling language that propose some graphical constructs to capture the interactions between organizations. We are interested to verify if they express what they are meant to express.

In this (short) questionnaire you are going to answer to several questions about the "design" of a choreography language.

The Image below, show a little example that illustrates the BPMN 2.0 proposal.

[All the diagrams are made using the great tool LucidChart : https://www.lucidchart.com/]

Exercise 3/4 - Meta-model Presentation

We will show you now two different ways of presenting a meta-model (several parts compose a meta-model).

A meta-model represents a way to describe a language.

Both of these two meta-models contain the same information but presented in different ways.

Let's focus on how well the information is presented (not necessarily in what the information is)

Meta-model 1 (choreography view)

Meta-model 1 (service view)

REF: http://www.omg.org/spec/BPMN/2.0/

What are the GOOD things of this Meta-model? (Concerning the way the information is presented)

For example: too many elements, the organization, etc...

What are the BAD things of this Meta-model? Concerning the way the information is presented

For example: too many elements, the organization, etc...

What are the main issues in this meta-model? *

Do not pay special attention to the information but the way it is provided.

Many classes

Many relationships

Many attributes

Text orientation

Inheritance Orientation

Other:

Required

Meta-model 2 (Conceptual level)

Thee Levels of Abstraction - Two View per Level

Meta-model 2 (Analysis level)

Analysis Level - Structural and Behavioral View

Meta-model 2 (Technical level)

Technical Level - Structural and Behavioral View

What are the GOOD things of this Meta-model? (Concerning the way the information is presented)

For example: too many elements, the organization, etc...

What are the BAD things of this Meta-model? (Concerning the way the information is presented)

For example: too many elements, the organization, etc...

What are the visual variables that may help you to read this meta-model? *

Color

Orientation (e.g., inherit class below parent class)

Packages

Brightness (clear vs obscure)

Views Separation

Levels of Abstraction

Other:

Required

Exercise 4/4 - Interaction Naming

Do you think it is appropiate to use the following naming convention for interactions ? In the example, the interaction name corresponds to the initiating activity *

Not at all

Absolutely

Choreography example

To what extent you consider important to standardize naming rules in models? *

Not important at all

Very Important

What is your usual practice when naming models (preferably business models) *

Standard conventions

Organization conventions

Own conventions

No conventions

Other:

In cases where is not that clear how to name model objects, you would prefer to... *

Use standard conventions

Use organization's convention

Use own conventions

Use no conventions
