CCSDS Theoretical Resource AllocationCCSDS Theoretical Resource Allocation

11 April 2005 7

• 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 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
