A software specialist explores available performance charts and diagrams to help their project lead with decision-making. What tenets make the control chart a viable option for the software specialist? (Select all that apply.)

It contains a center line, which serves as the mean, a UCL, and an LCL. It uses mathematical rules to decide if the fluctuations observed are unusual or just the typical variation in a process. It uses a process's standard deviation to calculate limits to determine if it is three standard deviations away from the mean.

It focuses on target work and actual work and uses a line or line/column chart. It helps manage scope and time.

A project manager (PM) wants to incorporate a performance chart into the project workflow to assist in developing decisions for the team. What are the benefits of the PM using a histogram over the use of a decision tree? (Select all that apply.)

It is a column chart used in statistical analysis. It is widely used in resource management and quality management.

A technician is tasked as project lead for an upcoming project and wants to identify available performance charts to ensure the technician meets all milestones. What are the benefits of the technician using a run chart? (Select all that apply.)

It is a time-based line graph also known as a time-series plot. It is simple to create and understand and can be used to review trends without statistical analysis.

A cyber engineer manages a project and wants to use various charts to assist in the next steps. Why would the engineer consider using a histogram for this project? (Select all that apply.)

It is used in resource management and quality management. It is a column chart used in statistical analysis.

An engineer drafts a project proposal and creates a section on performance charts and diagrams. Upon careful evaluation, the engineer proposes using a control chart. Which element does the engineer NOT include when considering control chart usage?

It measures how many story points are completed per iteration, contains several previous iterations, and usually plots an average for the iterations shown.

A project manager wants to use charts to help them make project decisions. What does the project manager gain from using a burnup/burndown chart?

It plots two values: target work and actual work.

A technician reviews various charts to determine the best course of action for the team's project. What is unique to a decision tree chart?

It represents a single choice that could have many outcomes.

A project lead wants additional insight on certain parameters within the project before making a decision. How would the use of a decision tree performance chart support the project lead's decision-making? (Select all that apply.)

It represents a single choice with the possibility of several outcomes. It asks a question, has numerous ways to respond, and can have several outcomes.

A software technician leads a project and wants to incorporate the use of a decision tree. Which tenets should the technician consider when working with decision trees? (Select all that apply.)

It requires an EMV calculation for each possible choice outcome. It represents a single choice that could have many outcomes. It consists of three parts; choice, option, and outcome.

A project manager reviews a factsheet on the value of velocity charts when making project decisions. What is unique to a velocity chart? (Select all that apply.)

It reviews historical performance and sets goals for upcoming events. It measures how many story points are completed in an iteration.

A technician explores methods to assist in decision-making processes and elects to use a performance chart. What are the advantages of using a fishbone diagram? (Select all that apply.)

It visualizes how various factors impact a single outcome and is also called a "cause and effect diagram." It helps identify multiple potential causes for a single problem.

A software engineer elects to use a scatter diagram to leverage information for decision-making during a project. What is unique to scatter diagrams? (Select all that apply.)

It works well with large data sets and creates an easy-to-read diagram. It graphically demonstrates the relationship between two variables.

A consultant reviews a team's new project to assist in decision-making. The project wants to capture the number of occurrences, by failure type, the team has seen in the past year. What can the consultant implement to provide a line and column chart that focuses on total percentages and counts in descending order?

Pareto chart

A decision tree

varies from a traditional flowchart in that it represents a single decision that could have many outcomes.

A project manager assigns an intern to a new project. The manager asks the intern to graph the relationship between two variables by using a dot for each (x,y) variable and report their findings to the team. What graph did the intern show the team?

Scatter diagram

A project lead asks a software specialist on the team to review the team's historical performance and set goals for the upcoming sprint. The specialist uses a diagram that measures how many story points are completed per iteration. What diagram is the specialist most likely using in this scenario?

Velocity chart

A technician creates a performance chart to support the team lead in project decision-making and recalls a performance chart that provides a center line, a UCL, and an LCL. What performance chart is the technician likely recalling from their prior training?

control chart

An engineer is assigned their first project. They want to explore various diagrams that can assist them in making project decisions. What diagram can the engineer use to track variations within a process?

control chart

A Pareto chart

displays how often something occurs using lines and columns. Each column represents the counts of a category, in descending order by total count. The line on the chart measures the total percentage of the count, which slopes upward.

A scatter diagram/scatter plot

graphically demonstrates the relationship between two variables. First, it plots two variables, one on the x-axis and one on the y-axis. Then, a dot represents the occurrence of each (x,y) variable.

A histogram

is a column chart used in statistical analysis where the x-axis shows a fixed series of continuous data and the y-axis shows the varying frequency that each value on the x-axis occurs.

A run chart

is a time-based line graph, also called a "time series plot." It shows time or sequence on the x-axis.

A velocity chart

measures how many story points are completed per iteration. The chart contains several previous iterations and usually plots an average for the iterations shown.

A software technician reviews charts that are aimed to support project decisions. What is also known as a "time series plot"?

run chart

Burnup and burndown charts plot two values:

target work and actual work. A burnup chart measures the total amount of work completed each day. A burndown chart measures how much work is remaining each day.
