A comparison of the Essence 1.0 and SPEM 2.0 specifications for software engineering methods

Abstract

In this paper we present a comparison of the draft Essence 1.0 and Software & Systems Process Engineering Metamodel (SPEM) 2.0 specifications for software engineering methods from the Object Management Group (OMG). The comparison is based on results from the REMICS research project where we are defining an agile methodology for model-driven modernization of legacy applications to service clouds. The initial REMICS Methodology was defined using SPEM. Selected parts of the methodology are now being redefined in Essence to evaluate its applicability, in particular its promise of better support for definition of agile practices and method enactment compared to SPEM. The comparison shows that there are similarities in the authoring capabilities provided by the two specifications, but that there are key differences in the method architecture with respect to support for enactment.

BPMN, SPEM e Essence no contexto da Modelagem de Processos de Software: uma Revisão Sistemática da Literatura

“…O estudo de [Elvesaeter et al 2013], por sua vez, compara as especificações do SPEM 2.0 e da versão de esboço do Essence 1.0 para métodos de engenharia de software. A comparação é realizada por meio de um exemplo ilustrativo baseado na prática Scrum, enfatizando os aspectos de capacidade de autoria de métodos e capacidade de execução (enactment) do processo em cada especificação.…”

“…O BPMN (Business Process Model and Notation) [Chinosi and Trombetta 2012], por exemplo, é uma notação para modelagem de processos focada no negócio da organização, que pode ser especializada para a modelagem de processos de software. O Essence [Jacobson et al 2012], por sua vez, é uma especificação que propõe suporte para a definição de práticas ágeis e melhor suporte para a execução de métodos [Elvesaeter et al 2013], por meio de um conceito de estados das entidades. Outra proposta, idealizada e desenvolvida pela OMG (Object Management Group), é o metamodelo SPEM (Software & Systems Process Engineering Metamodel) [Bendraou et al 2007, Bezivin 2005.…”

A Representation Proposal of Practices for Teaching and Learning Software Engineering Using a Semat Kernel Extension

“…When users of a software development approach work in a particular and repetitive way, and the approach addresses several dimensions of software development, it is said to be a development method. Before Essence, users represented their methods with other standards [33][34][35]. For these representations, users make their methods mainly with activities and other elements.…”

Modeling Software Product Line Engineering with Essence Framework

“…Both SPEM and Essence framework provide a language to define methods. In [8], the authors present a comparison of Software & Systems Process Engineering Metamodel (SPEM) 2.0 and the draft version of Essence Specification 1.0. The Essence framework, however, also provides a generic domain model of software engineering defined in Essence language (e.g.…”
