Service Oriented Architecture (SOA) is a paradigm that provides important advantages like interoperability, reusability and flexibility, particularly beneficial for B2B applications. In the current paper, we consider specific architectures of inter-organizational workflows (IOWF) fairly widespread in the B2B area and implementing different cooperation schemas. Our aim is to propose new generic IOWF-architectures by using the SOA paradigm in order to obtain IOWF models flexible enough to ease their adaptation, evolution and reuse. For that, we introduce the concept of Service-Based Cooperation Pattern (SBCP) that supports the definition of IOWF models based on services. A SBCP is defined by three main dimensions: the distribution of services, the control of execution and the structure of interaction between services. Also, we define a concept of composite cooperation pattern based on the combination of elementary patterns. We illustrate our approach by a general description of our cooperation framework called “S-IOFLOW” that supports the implementation of IOWF models obeying to the described SBCP. Three main points characterize our approach: (i) the use of a pattern-based approach; (ii) the definition of composite patterns by reusing elementary ones and (iii) the support of several cooperation schemas with different types of control.

This paper aims to define an adaptive guidance for software process modeling. The proposed guidance approach is based on development’s profile context (actor’s role in the process, actor’s qualification and related activities in progress). We introduce new guidance concepts through adaptive guidance meta-model (AGM) allowing specific assistance interventions (corrective, constructive and automatic guidance). We illustrate our guidance approach using SPEM formalism extended with these new guidance concepts.
