Co Context

  • Unified Model Language (UML)
  • Graphical representations to denote diverse aspects of

software

  • States, activities, components, objects, and classes
  • UML is widely adopted on Industry
  • Is considered by many the de facto standard for

software modeling

  • The Use of UML in practice is a topic of interest of

researchers on software engineering

  • Several studies investigate the practice of UML in

industry

How do we use UML? Is it cost-effective? What is the cost/benefit? Pros and cons? How can we improve? Or we should not care? Questions researchers have asked:

Great part of developers make a selective use of UML i.e. they use UML in a informal and personal way for as long it is considered useful; Models are usually discarded after their conception

Design models are not used very extensively in industry. UML is used with minimal tool support. The notation is not necessarily UML.

UML benefits collaboration and communication (especially within teams geographically distributed).

Recent t research findings:

There is a possible association between cultural differences and modeling usage, which was considered worth exploring in the future.

Ga Gaps in Related Work:

  • Most of them did not target UML practice

specifically on industrial closed source projects.

  • Or they were restricted to participants from a single

company.

  • They did not focus on:
  • Analyzing whether or not the type of participants’
  • rganization affects UML use.
  • A particular geographic region.

Ou Our focu cus:

Software engineers who work in industrial closed source projects. Assess the UML practice in a particular geographic region.

  • Do previous findings hold?
  • Or do they vary?

Go Goals

  • G1: understand the diffusion and relevance of UML

use in the Brazilian companies;

  • G2: identify improvement points to increase the

UML adoption in real-world projects.

Re Research Questions

SEKE 2018

  • RQ1: How frequent do software engineers use UML

in practice?

  • RQ2: Is UML the “lingua franca” for software

modeling?

  • RQ3: What improvement points may increase the

UML use?

A sample of 113 participants from 222 was extracted to evaluate statistically if the UML usage could be influenced by the type of the company (software factory or not) Statistical tests show that there is no relation between using or not using UML and whether the company is a software factory or not.

Conclusion #1:

  • UML is not used very often in the work life of

participants.

  • No relationship was identified between the use of

UML and whether or not participants’ company is a software factory.

Conclusion #3:

view of the system under development;

  • Provide diagrams/views filtered by system features;
  • Support more effectively:
  • round-trip engineering; and
  • modeling collaboration.

Final Final Rem emar arks

SEKE 2018

  • This work sought to find evidence of how

UML is used in practice focused on:

  • Particular geographic region (Brazil);
  • Practitioners who work on closed source

projects.

  • In total, 222 participants from 140 IT

companies.

Final Final Rem emar arks

SEKE 2018

  • Overall, our results show that UML use has

not varied much by region.

  • In our context:
  • The majority have not used UML in their work

life.

  • Everyone knows UML but they don’t necessarily

agree it is a “Lingua Franca” for software modeling.

  • The majority pointed out tool related

improvements to boost UML use. Perhaps this requires changes in the language.

  • Further investigation on:
  • Motivating factors for UML adoption;
  • Perceived cost/benefit of UML from the

perspective of academics and practitioners.

  • Analyze more data we already collected from the

same set of participants.

  • Assess to what extent UML modeling tools:
  • Support round-trip engineering; and
  • Collaborative modeling.
