Augment your traditional expert estimation with parametric estimation to reduce surprises.
Application Development Managers have to defend maintenance budgets to executives.
Often the estimates are based on a single method – expert estimation – instead of also including parametric estimation in the process.
The result is a variance in estimated and actual budgets caused by varying degrees of scope interpretation by experts who are called upon to estimate.
Having a single expert estimation technique is not enough. You need to include an analytical parametric technique to quickly surface assumptions and have that discussion early rather than having to defend a budget shortfall.
