The Cost Analysis Division at NASA HQ is in the process of completing a new version of the Cost Estimating Handbook (CEH). The CEH will be available from this website as soon as it has been published.
The new CEH will contain many updates since the prior release in 2008. The upcoming CEH will be published electronically in PDF format along with multiple detailed appendices. All electronic files and information related to the CEH will be placed on this webpage once the handbook has been published.
2013 CEH Status: Coming Soon! (as of 22 Jan 2013)
