Exam 5: Scheduling the Project

Gantt charts are not adequate replacements for networks.

When it was originally developed, PERT used certain (deterministic) methods to estimate activity duration.

Critical path tasks always have zero free slack.

Scum takes a more just-in-time (JIT) approach to project planning whereby planning is done as late as possible and when the most is known about the project.

Networks are usually drawn with a "Start" node to the right and a "Finish" node to the left.

We can find the probability by finding z using which of the following equation?

Slack is calculated as?

Scrum employs a consensus-based approach to develop estimates for the effort required to complete each product requirement listed in the product backlog. This consensus-based approach is called what?

The movement from left to right through the network beginning with the start node that calculates the LS and LF for each activity is known as "forward pass".

Verita Nist, an automobile company, sought to improve the production time and quality of its products within a year. In the first month, the company installed five new assembling machines. This reduced the production time by 15 percent. In the context of the language of the Program Evaluation and Review Technique (PERT) and the Critical Path Method (CPM), this decrease in the production time of Verita Nist's products is an example of a(n) _____.

There is more than one way to compute slack.

When conducting risk analysis on a project, we always know which path will be the critical path.

Consider a project network that begins with activity A and is followed by activity B. Activity A takes 6 days to finish. If the earliest start time for activity B is 6 days and the latest start time for it is 10 days, activity B has a slack of _____.

Define the term critical path.

What is a merger and what problems do mergers create?

Miros Inc., a recording studio, displays its recording process by using a network of nodes and arrows. The nodes are used to depict the activities involved in recording a song, such as setting up the instruments, and the arrows are used to depict the order of precedence of the activities. Which of the following project networks is Miros using in the given scenario?

When calculating the variance of an activity, the formula is σ2=b-a26 is the correct formula no matter what probability is used to estimate b and a.

The simulation approach is generally preferred over the statistical method.

The difference between LFT and EFT is called slack.

What are the four methods of linking steps in a project using precedence diagramming?
