==== IBM Rational Telelogic Harmony-SE ====

=== Overview ===

  * Service Request-Driven Approach
     * Described by means of SysML structure diagrams
     * State/mode changes (activities ) described as operational contracts

  * Somewhat mirrors “Vee” model

  * Task flow and work products (artifacts) include following top-level process elements:
    * Requirements Analysis
    * System Functional Analysis
    * Architectural Design

  * Detailed task flows and work products provided for each process element
    * Modeled as SysML activity diagrams

=== Tool Support ===

  * Harmony-SE (and Harmony) were created as tool- and vendor-neutral, model-based methodologies. No process framework tool exists from IBM Rational/Telelogic or third-party provider.

  * Tool support for MBSE that supports the methods specified by Harmony-SE and Harmony is, of course, provided by IBM Rational/Telelogic via the Tau and Rhapsody product offerings.

=== Offering/Availability ===

  * Harmony-SE/SysML Deskbook has been published to help guide the systems engineer and project manager through the entire MBSE methodology. In addition, IBM Rational/Telelogic offers professional services to support methodology adoption.
