==== Fernandez ISE & Process Pipelines in OO Architectures (ISE&PPOOA) ====

=== Overview ===

  * **ISE&PPOOA (Integrated Systems Engineering and PPOOA)** provides  an integrated process and methods for systems engineering of software intensive mechatronic systems.

  * The **ISE part of the process includes the first steps of a systems engineering** process applicable to any kind of system, not only the software intensive ones. The ISE subprocess integrates traditional systems engineering best practices and MBSE.

  * The **PPOOA part of the process** emphasizes the modeling of concurrency as earlier as possible in the software engineering part of the integrated process.

  * PPOOA is also an architecture framework for real-time software: [[http://www.iso-architecture.org/ieee-1471/afs/frameworks-table.html]]

  * The integration between the systems engineering  subprocess and the PPOOA software engineering subprocess is achieved by using a **responsibility driven software analysis** approach supported by CRC cards, a technique proposed in the OOPSLA´89 by Beck and Cuningham. 

  * ISE&PPOOA provides a **collection of guidelines or heuristics** to help the engineers in the architecting of a system.

  * One of the project deliverables is the **functional architecture** representing the functional hierarchy using the SysML block definition diagram. This diagram is complemented with activity diagrams for the main system functional flows. The N square chart is used as an interface diagram in the shape of a matrix where the main functional interfaces are identified. A textual description of the system functions is also provided as part of the deliverable.

  * Other of the deliverables is the **physical architecture**, representing the system decomposition into subsystems and parts using the SysML block definition diagram. This diagram is complemented with SysML internal block diagrams for each subsystem and activity and state diagrams as needed. A textual description of the system parts is provided as well. The **heuristics** used for the particular architecture solution are identified and documented.

  * The **software subsystem architecture** is described in PPOOA using two views supported by one or more diagrams using UML notation. One view is the static of structural view and the other is the dynamic or behavioral view of the system. The system architecture diagram represents the system components and the composition and usage relations between them. Coordination mechanisms used as connectors are also represented. The system behavioral view is supported by  UML/SysML activity diagrams representing an internal view of the flow of actions performed by the system in response to an event

  * Bidirectional functional allocation between components and system responses modeled as activity diagrams is considered and tool supported

  * ISE&PPOOA makes easy the architecture evaluation from time responsiveness characteristics

  * ISE&PPOOA/Energy is the latest process of this MBSE method. ISE&PPOOA/Energy is used to deal with energy efficiency issues in industrial facilities. See the resources section for recent published papers dealing with examples of application.

=== Tool Support ===

  * **ISE&PPOOA MBSE methodology was created as tool- and vendor-neutral**. Currently we are using diverse commercial SysML tools as it can be read in our articles and papers dealing with examples.

  * Tool support for architecting software with PPOOA software architecture framework is provided via a free add-on for Microsoft Visio 2003 that can be requested to ise&ppooa@ppooa.com.es. This tool supports software architecture developing, documentation generation and the interoperability with other execution simulation and schedulability analysis tools (for example the Cheddar tool from the University of Brest)[[http://beru.univ-brest.fr/cheddar/]]
