Post-4.5 Discussion

• Due to limited resources, no planned enhancements (without resources) and only defect fixing for post-4.5.
• Interest in slimming/flattening the organization of the project.
  • One person would do the scheduling.
  • One person would do mentoring/policing.
  • Project Leads would not handle resource allocation and scheduling.

• Alex will not be contributing to the project post-4.5.

• We need to close the post-4.5 resources over the next two weeks.
  • Joanna will discuss with IBM in preparaton for the May 21 PMC call.

Action Items

• Oliver to send an email to SAP informing them of our decisions on integrating the TPTP and SAP heap profilers.

• Project Leads will update this WIKI page with the complete list of 4.5 deferred enhancements and defects.
  • Project Leads will send out note to PMC mailing list when complete.

• Project Leads will review the updated list of 4.5 deferred enhancements and defects and discuss any concerns on Wednesday's PMC call.

• Joanna will discuss post-4.5 resources with IBM in preparaton for the May 21 PMC call.
