6. 6 11 April 2005 CCSDS Theoretical Resource Allocation

7. 7 11 April 2005 Frequent (6-month) update of Operating Plan is not occurring, often because: - It’s not perceived that the resource allocation is being affected, because: - In reality, Agencies allocate resources on a longer timescale: - Typically, yearly CCSDS Theoretical Problems

8. 8 11 April 2005 CCSDS Requested Operating Plan, along with a resource request matrix, will be drafted in May after the Spring meeting to cover the 12 month work Fall to Fall work period CMC will respond in a timely manner (June) with a draft resource allocation matrix for the upcoming 12 month work period CESG will reflect the allocations in an updated draft Allocated Operating Plan (July) that covers the upcoming 12 month work period CMC will confirm this at the Fall meeting After than point (September), the only changes for the upcoming 1-year period will be: If a new WG is requested to be chartered If an existing WG needs to request a change in its resources or schedule The cycle repeats each Spring Proposed New Work Cycle
