The document presents BVCCoN-Tool, a modeling tool developed to support the BVCCoN approach for dynamically configuring business processes. BVCCoN-Tool was built using modeling frameworks like EMF, GMF and Epsilon. It allows modeling the variability, context and non-functional requirements views required by the BVCCoN approach. An evaluation with students found the tool useful, with good overall satisfaction and system utility. Future work aims to perform more evaluations and extend the tool to automate business process configuration.

Motivation
• BVCCoN Approach;
• BVCCoN is composed of five main tasks:
 (1) – Elicit variability;
 (2) – Describe variability;
 (3) – Analyze context;
 (4) – Link NFRs and Variants; and
 (5) – Perform configuration.

4. CIn.ufpe.br4
Motivation
• BVCCoN is too complex, because it is related to business process
model, non-functional requirements model, and context information
model;
• These models are built in steps 2, 3 and 4 of the approach;
• IMPORTANT: More than half of approach execution is performed
through the construction of models;
• The lack of a tool makes the process slower, hard to understand
and error prone.

5. CIn.ufpe.br5
Goals
• To address this shortcoming, we present BVCCoN-Tool, a modeling
tool based on a metamodel that is capable of supporting all modeling
steps of BVCCoN approach;
• Present an usability evaluation with post-graduate students to
evaluate the usefulness of the system;

BVCCoN-Tool Development - Technologies
• To the development of BVCCoN-Tool, we used a set of unified
modeling frameworks, tools, and patterns implementation found in
Eclipse Community;
• EMF (Eclipse Modeling Framework);
• GMF (Graphical Modeling Framework);
• Epsilon;

10. CIn.ufpe.br10
Technologies - EMF (Eclipse Modeling
Framework)
• Ecore Metamodel;
– EClass;
– EAttribute;
– EReference;
– EEnum;

11. CIn.ufpe.br11
Technologies - GMF (Graphical Modeling
Framework)

12. CIn.ufpe.br12
Technologies - Epsilon
• Epsilon is a family of language and tools to support the
management of metamodels;
– EuGENia;
– Emfatic;
– EOL (Epsilon Object Language)
– EVL (Epsilon Validation Language)

13. CIn.ufpe.br13
Technologies -
Emfatic and EuGENia
• Emfatic Metamodel;
• EuGENia Annotations;

Presentation of BVCCoN-Tool
• The metamodel of BVCCoN-Tool was built in a way that it can
prevent syntatic errors.

Usability Evaluation
• Scenario: Airport Check-In
• Reference Process

18. CIn.ufpe.br18
Usability Evaluation
• PSSUQ – The Post-Study System Usability Questionnaire – IBM;
 Overall satisfaction;
 System utility;
 Information quality;
 Interface quality;
• Widely used in academia;
• Cited by 933 works;
• Meets research objectives;

19. CIn.ufpe.br19
Usability Evaluation – Utility of the System
Average “no opinion” = 24;
General average = 30.71;
The tool was considered useful by the users. Therefore, the tool
performs tasks that it claims to do.

Conclusion
 Through BVCCoN-Tool, three views (non-functional requirements,
variability and contextual information) were modeled;
 According to the users, the usability evaluation had a good
acceptance, concluding that the tool use is viable and practical to
be used in real environments;
 We found evidence that our tool can serve as vehicle for
improving the quality of the models and time consuming of
BVCCoN approach.

22. CIn.ufpe.br22
Conclusion – BVCCoN Strengths
• (1) Import BPMN models;
• (2) Is possible to model three views independently;
• (3) Interactive feedbacks; and
• (4) Usefulness of the system;

23. CIn.ufpe.br23
Future Works
• (1) Execute a pilot project in industry;
• (2) Perform other usability evaluation; and
• (3) Extend the tool to automate the configuration of dynamic business
process;
