OSLC PLM Workgroup1 Towards detailed use cases and alignment to OSLC V0.1 Gray Bachelor 18 th July 2011

OSLC PLM Workgroup2 Pains to target Increasing time and cost to manage integrity of complex system designs and its relevant requirements Increasing impact of an error arising from system design not updated correctly from changes Increasing need to coordinate work across larger and more dispersed work locations and organisational responsibilities

OSLC PLM Workgroup3 Business goal To reduce the time and cost to manage changes to complex systems arising from changes to requirements

OSLC PLM Workgroup4 There are 3 related concerns The primary domains of the target operating environment are  Product design  Enterprise integration  Corporate compliance

OSLC PLM Workgroup5 Product design

OSLC PLM Workgroup6 Existing OSLC sources Activity diagram  Who does what when Sequence diagram  Which system component does what when

OSLC PLM Workgroup7 Which roles Product change administrator (Should System Engineer (Must Sub-system owner (Should Software Engineer (Could Business analyst (Should IT administrator (Could Enterprise Integration developer (Must Application support leader (Could

OSLC PLM Workgroup8 Which scenarios OSLC PLM SE Scenario #1  A Systems Engineer responds to a change in requirements OSLC PLM EI Scenario #1  A Business Analyst identifies required information and process support for a SE scenario  An Integration Developer delivers process support through enterprise integration  An IT administrator deploys process support to users  An Application support leader handles problems with the deployed process support

OSLC PLM Workgroup9 Outline of Scenario #1 1. Assign & communicate the change request ( a1, a2, a3) Assign change request context Communicate change request Locate change request from notification 2. Apply request context to establish impacted requirements & implementation (a4, a5, a6) Locate requirements in change request context Create new revision of requirements context and reserve for editing Open new revision of context 3. Locate re-usable implementations to meet changed requirements (a7) Located reusable implementation to satisfy change? (A decision that drives alternative flows) 4a. Either update solution by way of adaption of re-usable implementations (a8, a9, a10, a13, a14, a15) Add selected implementation to change request as solution Merge selected implementation into context Trace to discipline responsibility Analyse detailed requirements & existing implementation Design minor updates to existing implementation Design by sub-team needed ? 4b. Or design solution by original design (a10, a11, a12, a15) Trace to discipline responsibility Design new implementation Add new design to change request solution Design by sub-team needed ? 5. Approve change request solution (a16, a17) Passed review of implementation for change request closure? Close change request * Note: 4 has alternative flows

OSLC PLM Workgroup13 SE use-cases (2 of Propose changes to requirements a7: Identify candidate solutions Update existing requirements a8: Add solution candidates to working set a7: Identify re-usable requirements Propose candidate solutions Collaborate with colleagues a14: Minor updates to solution Commit changes to requirements Gain approval for requirements changes a7: Identify impacted requirements Gain approval for system level candidates Gain approval for system level changes a9: Assess impact of working set changes Notify colleagues Search requirement catalog Search system catalog

OSLC PLM Workgroup14 SE use-cases (3 of Verify systems level design a11: System level design to meet changed requirements Propose system level changes Commit system level changes Gain approval for system level changes a12: Add system level design changes to solution proposal Collaborate with colleagues Notify colleagues Manage system level design changes
