Once the organization elevates its constraint,its system has no constraint.

Your next project consists of 8 consecutive 8-day activities,each estimated by a different worker in your organization.Your organizational culture dictates that you add your own safety margin of 3 days into your estimates.Unbeknownst to you,the project manager has recently converted to a critical chain project management view.The project manager knows perfectly well what sorts of games are played with activity estimates and she knows exactly how much activity padding takes place.What will the overall project safety margin be once the project manager reviews your estimates and makes the project schedule?

Subcontractor deliveries are difficult to schedule with the critical chain project methodology because:

The term capacity constraint buffer refers to a safety margin separating different tasks scheduled to use the same resource.

The buffers supplied to non-critical paths in critical chain project management are called:

A project consists of four activities with information as shown in the table.What is the overall variance of the project's duration?

A product backlog is the final list of what is needed to complete the project.

The critical chain is usually the same as the critical path.

Which statement about critical chain project management is BEST?

The waterfall project development process is well-suited for instances where:

Which of the following statements about CCPM activity networks is CORRECT?

A key element of extreme programming is:

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? $\begin{array} { | l | l | l | l | l | l | } \hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Activity } & \text { Predecessor } & \text { Length } \\\hline \text { A } & - & 18 & \text { E } & \text { C, D } & 13 \\\hline \text { B } & - & 16 & \text { F } & \text { C } & 9 \\\hline \text { C } & \text { A } & 22 & \text { G } & \text { E, F } & 15 \\\hline \text { D } & \text { B } & 14 & & & \\\hline\end{array}$

CCPM advocates performing all non-critical activities:

What is Agile PM and what makes it ideal for many software development projects?

A project consists of four activities with information as shown in the table.What is the overall standard deviation of the project? $\begin{array} { | l | l | l | l | } \hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Variance } \\\hline \text { A } & - & 10 & 4 \\\hline \text { B } & \text { A } & 12 & 3 \\\hline \text { D } & \text { B } & 16 & 5 \\\hline & \text { C } & 14 & 6 \\\hline\end{array}$

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 the project buffer if this project is managed using critical chain methodology? Use the rule of thumb approach. $\begin{array} { | l | l | l | l | l | l | } \hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Activity } & \text { Predecessor } & \text { Length } \\\hline \text { A } & - & 18 & \text { E } & \text { C, D } & 13 \\\hline \text { B } & - & 16 & \text { F } & \text { C } & 9 \\\hline \text { C } & \text { A } & 22 & \text { G } & \text { E, F } & 15 \\\hline \text { D } & \text { B } & 14 & & & \\\hline\end{array}$

Which of these numerical (quantity) comparisons is CORRECT?
