A Tool and a Formalism to Design and Apply Patterns

Usability Pattern Identification Through Heuristic Walkthroughs

“…According to Conte (2002), pattern relations in general can be of the following four types: P A uses P B , P A refines P B , P A requires P B , P A is an alternative for P B . All relations in the pattern collection will be created according to these basic types.…”

Component-based process for modeling language evaluation

“…It is composed of a set of rubrics. To define our process design pattern, we use the P-SIGMA [5] model that we adapt to take into account the capitalization needs. Moreover, we add some rubrics and customize others.…”

A method to build information systems engineering process metamodels

“…This is mainly because no common formalism for patterns representation exists. P-Sigma thus offers a way of expressing a semantics that is common to the majority of formalisms proposed in the literature, in order to make a uniform expression of product patterns and process patterns, to make explicit the pattern selection interface and to allow a better organization of patterns libraries (Conte et al, 2002). In other words, the representation of the metamodelling patterns, business patterns and process patterns of the method is homogenous, which will ease their comprehension and selection.…”

“…We use the P-Sigma formalism (Conte et al, 2002) to represent all the patterns. These patterns form a pattern system.…”

“…All these patterns are represented in the P-Sigma formalism. We also use a tool, AGAP (Conte et al, 2002), a development environment that allows building and managing pattern formalisms and pattern systems. All the patterns of our method are stored in the AGAP pattern system.…”
