A project is represented by the activity durations (in days,estimated at 90% likelihood of completion)and precedence requirements shown in the table.How many feeder buffers are needed if this project is managed using critical chain methodology? $$\begin{array} { | l | l | l | l | l | l | }
\hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Activity } & \text { Predecessor } & \text { Length } \
\hline \text { A } & - & 18 & \text { E } & \text { C, D } & 13 \

In critical chain project management, feeder buffers are added where non-critical paths feed into the critical path. Here, activities E and F feed into G, which is on the critical path, requiring two feeder buffers.

A Project Is Represented by the Activity Durations (In Days,estimated
