A project consists of four consecutive tasks that have average duration and worst$-$case duration estimates $($in days$)$ as shown in the table. Use Newbold's model to determine the aggregated buffer of one standard deviation for this project.

$2$

A project consists of six consecutive tasks that have average duration and worst$-$case duration estimates $($in weeks$)$ as shown in the table. Use Newbold's method to determine the aggregated two sigma buffer for this

project.

$6$

A project is represented by the activity durations $($in days, estimated at $90\%$ likelihood of completion$)$ and

precedence requirements shown in the table. What is the length of a feeder buffer if this project is managed using critical chain methodology?

Activity

$3$ days

$4$ days

$7$

A project consists of six consecutive tasks that have average duration and worst$-$case duration estimates $($in days$)$ as shown in the table. Use Newbold's method to determine the aggregated two sigma buffer for this project.
