Instructions:
Enter the a,m, and b values for each Task into columns C,D and E. The E and SD values for each task will be calculated and displayed in
columns F and G. A task estimate with at least 95% confidence and the required task booking value is calculated and displayed in columns H
and J.

Based on the individual task estimates the E value and SD for the project will be calculated and displayed as will the overall work estimate for
the project with at least 95% confidence levels.

          Notes and Assumptions

          The bulk group change facility is being delivered and billed as part of ITS029 and is therefore not included in this estimate (as per
          discussion with Bill Lee 31.05.10 - Richard Good's feedback to Bill).

          This estimate assumes that Aluminati will provide appropriate data encryption to recognised standards (SSL).

           Update architecture documentation - Dev Tech:
           added 0.5 day but this will be accounted for
           under original estimate of 29 days.
