SEEDS: Strategic Evolution of ESE DATA Systems
(Formerly NewDISS: New Data and Information Systems and Services)

Purpose       Approach      Schedule       Status      Documents

Purpose

• Determine if a SEEDs software reuse and reference architecture effort can:
  • Reduce the cost and improve the delivery of information services needed by future NASA Earth Science Enterprise missions,
  • Increase flexibility and responsiveness of systems to new missions, science and applications use of NASA data,
  • Increase effective and accountable involvement of the community.
• If so, define the processes and mechanisms needed to achieve these benefits.

Approach

• Phase 1:  Preliminary options identified, trade study and analysis
  • Obtained by interviewing experts, surveying members of the ESE community and reviewing documented case studies, reports and papers from broad range of industry, academia, and government agency lessons learned.
  • Outcome: identified a range of applicable software reuse and reference architecture options along with list of criteria for evaluating these options.
• Phase 2:  Formal solicitation and compilation of community views
  • Views gathered during community workshops and one-on-one interviews.
  • Outcome:  confirmed that community opinion bifurcates along the mission-critical and mission-success themes, compiled each community’s views on general process guidelines, program strategies, reference architecture purpose, and evolution and enablement strategies.
• Phase 3: Development of community-based processes for each community
  • Focusing on government & community collaboration and evolutionary processes that meet each community’s needs.
• Phase 4: Implementation of recommended community processes
  • Subject to headquarters approval, availability of funding and working group formation.

Schedule

• February 2002: Trade study and analysis (workshop 1)
• May 2002: Compilation of community feedback on options and suitability.
• June 2002: Solicitation of community input on process guidelines and strategies (Workshop 2).
• September 2002: Process recommendations due to ESDSWG formulation team.
• March 2003: Solicitation of community input on process details, working groups’ roles and responsibilities and potential barriers to success (Workshop 3).
• April 2003: Refined reuse process.
• April-August 2003: Definition of strategy and implementation plan.
• June/July 2003: Formation of working groups (pending approval).
• July 2003-2004: Support of working groups (pending approval).
