2 SNECMA CONTEXT Development methods unit rebuilt last year Many projects to improve the maturity level of the R&D teams, including: Processes update & access modification MBSE process implementation Future systems development frameworks evaluation Textual requirements quality & KM improvement through boilerplates & ontologies use 2 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

3 SNECMA NEEDS Observations The Snecma quality repository is too rarely used and unknown by the users The documents are not up to date The repository does not contain the processes instanciations for the different engines programs (and is not supposed to) Causes It is necessary to go through the entire breakdown structure and inside the documents to find the right information and the document Ergonomics It is impossible to see the low level processes structure It is impossible to easily navigate through the processes Research engine Trainings Objectives Enhance the accessibility to the processes repository Ease the repository maintainability Enhance the use of instanciated processes by the programs users Approach : build a wiki type repository allowing the user to find quickly and simply the information about the concerned activity 3 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

4 SNECMA NEEDS Two tools evaluated and compared to meet our needs: IBM Rational method composer Atego Process director Evaluation towards the following high level needs: Capability to model both high and low level processes (from the V cycle to the changes management process) Capability to simply search on the processes content Ergonomics Capability to instanciate the generic processes for each program Maintainability Capability to be easily deployed 4 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

5 EVALUATION OF ATEGO PROCESS DIRECTOR VS IBM RATIONAL METHOD COMPOSER Criteria Atego process director IBM Rational method composer Capability to model the processes + Difficulties to model some complex nested loops (change mgt process) Search on the content ++ Key words, tags Ergonomics ++ Nice interface Capability to instanciate generic processes for programs Maintainability ++ History mgt for each page Easily deployed ++ Web client Need to braoadcast a new process after each modification ++ Web client Cost / 3 years ~32k / 3 years ~15 k / 3 years Snecma choice 5 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

6 ATEGO PROCESS DIRECTOR KEY ADVANTAGES BPMN compatible, metamodel that can be tailored From high to low level processes (including tools instructions) Ergonomics Search (tags, key words ) Web client, links with other web client tools Capability to connect to a user LDAP Instanciations in delta with the generic processes History management 6 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

7 APPROACH Meta-model to be built first (with implementation in the tool) High level draft modeling of the processes in visio (block diagrams) Bottom up approach from activities to proccesses Detailed implementation in APD to consolidate the drafted structures Processes added incrementally (still in progress) Requirements management Verification Corporate high level processes designed and stored in ARIS, connected to APD 7 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

8 PROCESSES METAMODEL IMPLEMENTATION 8 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

9 FEEDBACKS Use at Snecma: Metamodel necessary before modeling processes (to avoid rework) Processes modeling easy for anyone Live processes modeling with users and non specialists accelerated (used for processes tailoring in Lean activities) Considered for management processes modeling and not only SE processes Tool limitations/suggested improvements: URL to be modified when processes renamed Links not updated when processes modified (should be optional) Bi-directional links not automatically updated Difficulty to model nested loops (artificial processes to be added as a patch) BPMN view sould be improved (for global view) Tailoring impossible in the BPMN view 9 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de

10 CONCLUSION Tool responding to our needs Simple and easy to use Like for any tool, needs a process and metamodel before deployment Anyone interested in exchanges on the topic is welcome at Snecma Villaroche Questions? 10 / Ce document et les informations qu il contient sont la propriété de Ils ne doivent pas être copiés ni communiqués à un tiers sans l autorisation préalable et écrite de
