Transcript

  • 1. DOORS RIF Capability Manageware
  • 2. A trend leading to complexity for data collaboration
    • URD, SOW, SRD…
    • Simplicity of requirement usage, format, traceability
    • Simple data management practices (Doc. Management)
    • Complex requirements using structure and relationships
    • Database management for requirements alignment
    • Tool alignment essential for data sharing
    Before Today 1…n Req 8.2 Req 3.2 Req 1.9 Req 1.2
  • 3. Today's DOORS Data Exchange Options
    • One of DOORS strengths is its communication of data
      • Principal focus on import and export
      • Or data exchange, limited to two databases, master and supplier
    • Existing interfaces include
      • Word Export/Import
      • Partition/Rejoin
      • Archive/Restore
      • CSV/TSV round trip
      • DXL based data Exchange Tools
        • Some internal to IBM
        • Others produced by partners
        • Several produced by customers
    There is a need to support more complex exchange scenarios
  • 4.
    • RIF (Requirements Interchange Format) from HIS (Hersteller-Initiative-Software)
      • Automotive industry initiative
      • http://www.automotive-his.de/rif/
    • Transition to Prostep iViP
      • Targeted to internationalize RIF
      • Not just focussed on Automotive
    • IBM to support RIF
      • Requirement to support open interfaces
      • Preference to support standards rather than IBM bespoke
      • Wish to harmonize data transfer in DOORS
        • Partition/rejoin, CSV roundtrip, more?
    An introduction to RIF – HIS Group and RIF
  • 5. An introduction to RIF – XML and RIF
    • eXtensible Markup Language (XML)
      • general purpose markup language
    • Facilitate the sharing of structured data across information systems
      • Data, Hierarchy, Tables, OLE, Relationships
    • Used to encode documents and serialize data
    RIF
    • Defined XML Schema
    • Word, CSV, PDF ( lossless ) exchange replacement
    • Exchange model for structured requirements
    So… what is RIF? Requirements Interchange Format
  • 6. An introduction to RIF - Structured Data Possibilities
    • Standardised information schema for cross tool compatibility
    • Meta-model extraction and replication
      • Hierarchy structures
      • Link structures
    • Rich Text Support
    • Direct DOORS benefits
    • 3 rd party exchange possibilities
      • Schema Interpreters
      • Graphical Schema Representation
      • Document Generation
    Req 8.2 Req 3.2 Req 1.9 Req 1.2 1 2 3 4 1 2 3 4
  • 7. DOORS 9.2 introduces native support for RIF
    • Built-in component of DOORS
      • Support for
        • RIF Export / Import
        • Multiple modules
        • Links
        • Delegated Data Control
          • Control modification of requirements
          • Control modification of attributes
    • Schedule
      • DOORS 9.2, available June 2 nd 2009, will support RIF export/import
      • A subsequent patch, planned for September 2009, will offer the rest of the functionality overviewed in this presentation
  • 8. DOORS 9.2 introduces native support for RIF
    • Fundamental use case to support supplier relationships
    • Step 1:
      • Distribute data to supplier database(s)
    • Step 2:
      • Concurrent working on data
    • Step 3:
      • Managed merge of data
      • With resolution for overlapping data

  • 9. What would we like to do with RIF?
    • RIF ensures requirements can be distributed with an expectation to bring updates back to the original location
      • Support for one or more modules, each using varying levels of control
      • Support for one or more suppliers
        • Requirements might be distributed across several databases
    • Level of data control defined by “delegated data control ( DDC )”
      • Single direction export or import – No DDC
      • Publication of requirements – DDC Read only
      • Outsource requirements production – DDC Full module
      • Distributed requirements feedback – DDC by attribute
      • Distributed requirements production – DDC by Object
  • 10. Let’s take an example
    • Example RIF packages could include
      • Export
        • Client shares vision data with a colleague
        • No DDC – Export Vision document with no expectation to receive it back
      • Supplier1
        • Client exchanges information with supplier
        • DDC Read Only – Supplier reads Vision document
        • DDC Full Module – Supplier develops Stakeholder and system requirements Supplier creates links back to the Vision document
      • Sub-supplier
        • Supplier exchanges information with sub-suppliers
        • DDC By Attribute – Sub-suppliers give feedback on stakeholder requirements
        • DDC By Object – Sub-suppliers develop sections of the System requirements
    Satisfies Satisfies Vision Stakeholder System
  • 11. Configuration of a RIF package
    • Configured through properties of a project
      • 9.2 limited to modules in a single folder
      • Patch expected to support modules from anywhere in the selected project
      • Note: A RIF package will always be exported as a single XML file
    • Scope of data defined by a configuration view
      • View defines requirements and attributes
  • 12. Identification of scope
    • Scope defined by configuration views
      • Requirements, controlled by filter
      • Attributes, controlled by columns in view
      • Types – restricted to data in view
      • Views – all public views transferred
    • Scope of links controlled by
      • Inclusion of link module in the package
      • Scope of source data
      • Scope of target data
  • 13. Single direction export or import – No DDC
    • No DDC indicates simple export of data
    • Don’t expect data to be returned
      • Unable to merge data if it is returned
    • Multiple export / import possible
      • Possibility to re-export updated data into a target database
    • Scope of data defined by a configuration view
      • View defines requirements and attributes
  • 14. Publication of requirements – DDC Read only
    • DDC Read Only indicates data is not expected to change in the exported data
    • Subsequent patch to support module baselines, pre-defined as DDC Read Only
    • Source database
      • Can continue to modify module
    • Target database
      • Imported data imported read-only
    • Import back to source
      • No merge required, data is read-only
      • Might be part of a returned RIF package to facilitate links
  • 15. Outsource requirements production – DDC Full module
    • DDC Full Module indicates target database has full control over the requirements
    • Source database
      • Once data is exported module becomes fully read-only, no changes possible
    • Target database
      • Imported module can be fully modified
      • Create, modify, move requirements
      • Creation of links only controlled where the link module is included in the RIF package
    • Import back to source
      • Imported module would effectively replace original module
      • All updates made in the target reflected back in the source
      • Original object IDs preserved
      • New object IDs will diverge between databases
        • To interact with other RM solutions, specific “RIF IDs” used to control data merge
  • 16. Distributed requirements feedback – DDC by attribute
    • DDC by attribute indicates that some attributes are expected to be modified
    • Attributes to be modified controlled by an additional module view
    • Source module
      • Once data is exported configured attributes become read-only
    • Target module
      • Configured attribute values can be modified
      • All other attributes read-only
    • Import back to source
      • Configured attribute imported back and merges into original module
  • 17. Distributed requirements production – DDC by Object
    • DDC by object indicates that some object hierarchies are expected to be modified
    • Object selection controlled by an additional module view
    • Source module
      • Once data is exported configured objects become read-only
    • Target module
      • Configured objects can be modified
        • Modify top level object
        • Create, delete or move children object
      • All other object hierarchies read-only
    • Import back to source
      • Objects merged back into original module
  • 18. Two stage import and merge process
    • Data imported back to a intermediary folder prior to merge
    • Merge takes imported data and merge applicable data back to the original location
    • Fully automated import then merge controlled by import
    • Hands-free control over RIF import/export possible through DXL automation
  • 19. RIF Locks
    • Exported data governed by Delegated Data Control will be locked
      • Locks only created after data is exported, not when the RIF package definition is created
    • Locks govern access control over
      • Modules – DDC Full module
      • Attributes – DDC by attribute
      • Object hierarchies – DDC by Object
      • No lock required – No DDC
      • No lock required – DDC Read only
    • Lock management
      • Possible for specific users to manually manipulate RIF locks
      • Merge capability revoked where a RIF lock has been removed
        • Not reversible
  • 20. Access controls
    • Based on DOORS partition/rejoin
      • Definition of RIF packages controlled by “Partition Data” power assigned to users
    • RIF package definitions need to be signed with both the database and project
      • Not possibly to copy RIF package definitions where copying a project
      • RIF package definitions not possible in module archive/restore
    • Top level 1 objects are always controlled with the first database that exported data
      • Possible to modify level 1 objects in target databases but not delete or move
    • Access policies can be passed from target databases to other target databases
      • Must have been granted write access over data in order to pass this access control on
  • 21. Use of a different RM tool as the target database
    • There is no assumption that a target database is DOORS
    • Where DOORS is not the target
      • View definitions will be ignored in the target location
      • No guarantees target tool fully supports access policies defined by RIF
      • Control over data modification also managed by DOORS on the return of any data
        • Data defined as read-only when exported from DOORS
          • Should not be modified in target tool
          • Updates which break the rules can not be imported/merged back into DOORS
      • Where DOORS is the target tool
        • If RIF locks are removed, data changes can not be brought back to the source database
  • 22. Points to note
    • Views
      • All views with default access of at lest READ will be exported
      • Attribute DXL exported as Text
      • Layout DXL only supported after the subsequent patch
      • Filters within a view might behave differently in different databases where references to system attributes are used
        • absolute numbers, created-by etc.
    • History
      • Can be included in exported data if displayed in a DXL column
      • History of imported data reflects merge operation in core history records
