Change:

&quot;2. Have each developer, tester, and other individual contributors estimate the effort required to implement the requirements that he or she will be responsible for.

&quot;B. Compare II.C to III.A(3). Compute a nominal estimate, N, using the following formula: (2 x TheHigherEstimate + TheLowerEstimate) / 3&quot;

Page 186: / should be *
On page 186, Step IV.A.1 contains an incorrect symbol.

Change:

&quot;1. Compute a revised nominal based on the following formula: RemainingEffort = PlannedRemainingEffort / (ActualEffortToDate / PlannedEffortToDate)&quot;

To:

&quot;1. Compute a revised nominal based on the following formula: RemainingEffort = PlannedRemainingEffort * (ActualEffortToDate * PlannedEffortToDate)&quot;

Page 273: Some of the &quot;Total volume of the Great Lakes&quot; answers are incorrect
On page 273, some of the &quot;Total volume of the Great Lakes&quot; answers are incorrect and need to be changed.
