Estimation Governance
 Governance framework for estimation
– RACI matrix, CRACK
– Who wants to take responsibility for estimation? 
 Actual data
– Collecting actual data is the biggest problem
– Projects start off with good intentions and collect metrics but
productivity metrics are not well maintained on completion.
Quality metrics are better than productivity metrics.
– Tools such as Jazz can be used for automatically gathering
data
