Discussions around processes,
  • Not following processes yields non-conformities
    gt
  • Some prefer multi-tier (processes, procedures,
    guidelines) with critical issues handled in less
    official/mandatory guidelines
  • Some prefer to leave alternatives (not even
    committing to DOORS)
  • Some prefer not to ask for too much (less
    attributes, no verification/validation results,
    only high-level requirements
  • More than just simple software gt
  • Requirements management is a complicated task
  • Cannot separate DOORS from tasks
  • Developing processes, guidelines, templates is
    engineering project gt start from needs /
    requirements, finish with (pilot) validation /
    verification (example SRE)

7
Backup as an example
  • DOORS server backups and restores are an example
    for requirements, yielding to guidelines, with
    validation needs (timeliness of backup, tests of
    continue working and data integrity, possibility
    of restores, regular restore tests, )

8
Regulations and software limitations
  • There is no history on links
  • Baselines have problems with links (see Pauls
    outlook on next DOORS versions)
  • Only the info on ID of object which is linked not
    on object text, attribute values, is saved
  • Need to baseline all modules simultaneously (does
    not reflect correct project status)
  • For look up only open one module, look up info
    on IDs of linked objects, then open corresponding
    baseline of linked module
  • Alternative Print out (paper or PDF)
    traceability column with relevant information of
    linked objects

9
Regulations and software limitations
  • Print-out and archival (alternatives paper
    scan, DOORS archives for milestones on CD, export
    to Word/PDF archive, DOORS server backups is
    archival)
  • Long-term requirement (if electronic, then need
    to maintain software for decades gt feasible for
    PDF but not for DOORS archives)
  • Change/revision control issues (rationales for
    change)
  • Data integrity issue
  • Electronic signatures (see DOORS 6.0 SR1)
  • Productivity issue (print-out, scan, archive,
    baseline, integration in archival system, )
  • Protection (fire, deletion, )
  • Money (DOORS licenses/availability, ) issues

You need to identify, validate, approve and then
follow process !
10
Document control (approval / change)
  • 820.40 Document controls (FDA Quality System
    Regulation)(see http//www.access.gpo.gov/nara/cf
    r/index.html)
  • (a) Document approval and distribution. Each
    manufacturer shall designate an individual(s) to
    review for adequacy and approve prior to ... The
    approval, including the date and signature of the
    individual(s) approving the document, shall be
    documented. ...
  • (b) Document changes. Changes to documents shall
    be reviewed and approved by an individual(s) ...
    Each manufacturer shall maintain records of
    changes to documents. Change records shall
    include a description of the change,
    identification of the affected documents, the
    signature of the approving individual(s), the
    approval date, and when the change becomes
    effective.

11
Linking and their analyses
  • There are plenty of analyses related to links /
    traceability which are enforced by regulations
  • Validation / verification coverage
  • Design coverage
  • Analysis of impact of a change (flow-down,
    flow-up)
  • Change analysis (suspect links)
  • You need guidelines on when / how to do those
    reviews / analyses you need to prove that they
    work you need to enforce them and you need to
    document them.

12
Some extraction from FDA 21 CFR 820
  • 820.3 Definitions
  • (h) Design review means a documented,
    comprehensive, systematic examination of a design
    to evaluate the adequacy of the design
    requirements, to evaluate the capability of the
    design to meet these requirements, and to
    identify problems.
  • (t) Quality audit means a systematic, independent
    examination of a manufacturer's quality system
    that is performed at defined intervals and at
    sufficient frequency to determine whether both
    quality system activities and the results of such
    activities comply with quality system procedures,
    that these procedures are implemented
    effectively, and that these procedures are
    suitable to achieve quality system objectives.
  • (u) Quality policy means the overall intentions
    and direction of an organization with respect to
    quality, as established by management with
    executive responsibility.
  • (v) Quality system means the organizational
    structure, responsibilities, procedures,
    processes, and resources for implementing quality
    management.
  • (2) Design validation means establishing by
    objective evidence that device specifications
    conform with user needs and intended use(s).
  • (aa) Verification means confirmation by
    examination and provision of objective evidence
    that specified requirements have been fulfilled.

13
Some more extraction from FDA 21 CFR 820
  • 820.30 Design control
  • (c) Design input. Each manufacturer shall
    establish and maintain procedures to ensure that
    the design requirements relating to a device are
    appropriate and address the intended use of the
    device, including the needs of the user and
    patient. The procedures shall include a mechanism
    for addressing incomplete, ambiguous, or
    conflicting requirements. The design input
    requirements shall be documented and shall be
    reviewed and approved by a designated
    individual(s). The approval, including the date
    and signature of the individual(s) approving the
    requirements, shall be documented.
  • (d) Design output. Each manufacturer shall
    establish and maintain procedures for defining
    and documenting design output in terms that allow
    an adequate evaluation of conformance to design
    input requirements. Design output procedures
    shall contain or make reference to acceptance
    criteria and shall ensure that those design
    outputs that are essential for the proper
    functioning of the device are identified. Design
    output shall be documented, reviewed, and
    approved before release. The approval, including
    the date and signature of the individual(s)
    approving the output, shall be documented.
  • (e) Design review. Each manufacturer shall
    establish and maintain procedures to ensure that
    formal documented reviews of the design results
    are planned and conducted at appropriate stages
    of the device's design development. The
    procedures shall ensure that participants at each
    design review include representatives of all
    functions concerned with the design stage being
    reviewed and an individual(s) who does not have
    direct responsibility for the design stage being
    reviewed, as well as any specialists needed. The
    results of a design review, including
    identification of the design, the date, and the
    individual(s) performing the review, shall be
    documented in the design history file (the DHF).
  • (f) Design verification. Each manufacturer shall
    establish and maintain procedures for verifying
    the device design. Design verification shall
    confirm that the design output meets the
    designPage 143input requirements. The results
    of the design verification, including
    identification of the design, method(s), the
    date, and the individual(s) performing the
    verification, shall be documented in the DHF.
  • (g) Design validation. Each manufacturer shall
    establish and maintain procedures for validating
    the device design. Design validation shall be
    performed under defined operating conditions on
    initial production units, lots, or batches, or
    their equivalents. Design validation shall ensure
    that devices conform to defined user needs and
    intended uses and shall include testing of
    production units under actual or simulated use
    conditions. Design validation shall include
    software validation and risk analysis, where
    appropriate. The results of the design
    validation, including identification of the
    design, method(s), the date, and the
    individual(s) performing the validation, shall be
    documented in the DHF.
  • (i) Design changes. Each manufacturer shall
    establish and maintain procedures for the
    identification, documentation, validation or
    where appropriate verification, review, and
    approval of design changes before their
    implementation.

14
Coaching / validation
  • Continuous coaching and validation are important
  • Provide general get started help
  • Quick routine checks (general structure, revision
    history, approvals, permissions, ) to catch
    standard errors / problems
  • Regular more detailed one-on-one checks (detailed
    structure, link set-up, OLEs, attributes, views,
    analyses, detailed permissions, DOORSNet
    publishing, baselines, deleted objects, printing,
    )
  • Real internal audits

15
Training
  • FDA requirement Engineers need to be trained on
    the tool (i.e. DOORS) AND the tasks (i.e.
    processes, procedures, guidelines)
  • Training needs to be documented

DOORSserver(Europe)
DOORSmodule
DXL
DOORSserver(US)
with Name, e-mail, system login, permissions,
training status, version, DOORS account infos
to create / update users and to extract user
information (which users who edited)
16
Training (pre work)
  • Develop templates and guidelines
  • Templates (with sections, standard text,
    attributes and attribute types, views, link set
    up, help, guiding, ) for
  • user requirements
  • system requirements
  • subsystem requirements
  • various test plans/results
  • use cases
  • Guidelines including
  • Contacts
  • Scope and traceability overview
  • Standards
  • New project set-up
  • Document life-cycle
  • Module templates
  • Various tasks in more detail

17
Traceability Guidelines - Training
  • Training curriculum based on DOORS guidelines
    ensured by links between both DOORS modules.
  • Training uses specific tasks from the guidelines
    as examples.

18
Electronic signatures (FDA 21 CFR 11)
  • Not having electronic signatures is for a lot of
    teams a real show stopper.
  • This is not only medical device industry
    relevant.
  • DOORS 6.0 SR1 is a great step in the right
    direction(electronic sign-off for baselines
    see Pauls demo)
  • Electronic signatures (and thus also baselines
    -) in DOORSNet would be even greater!
  • Problem long-term archival
  • Processes / guidelines are important.

19
Software installations / upgrades
  • DOORS upgrades are cumbersome
  • Clients and multiple servers may have to be
    upgraded simultaneously
  • DOORS 4.1.4 SR2 to DOORS 5 can basically be done
    project by project
  • DOORS 5 to DOORS 6 need to be done for all
    projects on a server simultaneously
  • It may be necessary to have different DOORS
    clients installed
  • Data may have to be migrated and migration
    requirements have to be identified, guidelines
    written and migration validated
  • New version has to be re-validated (deficiencies
    need to be treated)

20
Software installations / upgrades
  • Telelogics DOORS install is not perfect. You
    may need to develop your own installshield
    install guidelines from your requirements and
    test it

21
Software installations / upgrades
  • Precise installation guidelines are important

22
Integrations with other software
  • DOORS is only one part of the puzzle!
  • Interface with configuration management
    (ClearCase, )
  • Interface with defect tracking (DDTS, ClearQuest,
    )
  • Interface with modeling tools (Tau, Rose, )
  • Embedded in Product Data Management (e.g.
    eMatrix)
  • Huge opportunities
  • Traceability among all product related data
  • Web-view on baselines
  • Issues
  • Permissions
  • 1-1 DOORS (project-gtfolder-gtproject-gtmodule-gtobjec
    t) to eMatrix translation is needed
  • Handling of DOORS attributes
  • Update of published information after
    update/deletion in DOORS

Summary / Questions
Summary / Questions
  • DOORS is a great tool!
  • But, requirements management (in particular) in
    big, distributed (maybe, multi-national)
    companies is not easy.
  • Regulations, audits, impose additional burdens,
  • FDA, FAA, are just acting in your interest !!!
  • Do not hesitate to contact me on details,
    trainings, consultancy
