EVM at CERN

- EVM for LHC- Much work done for implementing EVM for LHC- CNGS decided to also apply this management tool- Autumn 2002 started to implement EVM for CNGS

PPT: Project progress tracking

• EVM project baseline frozen 9 May 2003

• 1st phase of utilisation and learning for the users:Project engineers are getting used to the system and the reporting.Analysing the results obtained from the EVM tools and proposing correcting actions.

Summary

Organised the CNGS tasks in a Work Breakdown Structure

Defined the Work Units required to complete the project(313 Work Units for CNGS)

EVM CNGS baseline frozen on 9 May 2003

Earned Value Management applied to CNGS- Work is in progress- Monitoring of the project’s progress started (one report per month requested)
