Need to Align Publication of Standardsand SW
Blocking

• April 6, 2005

2
Problem

• System Implementers need Standards and SWBlocking
  Cycles Aligned
• Some Block TV-1s Have Old Versions of Standards
• Some Standards are Published Well Into Execution
  Phase
• ICPs and SCCs Need to be Managed for SWB Blocks

3
TV-1 Revision Frequency

• SW Blocking
• New Requirements Every 18 Months
• New SW Fielded Every 18 Months
• Standards
• New VMF Every 2 Years
• New USMTF Every 1 Year
• 6016 Every 16 to 30 Months
• 47001
• 188-220
• 2525 Every TBD

Recommendations

• Work with Standards Groups to Get Standards
  Published within the Preparation Phase of
  Implementing Block
• Limit Changes (e.g. ICPs, SCCs, CPs) with a
  Cut-off Date Early in the Execution Phase
