Six Sigma 1.8

What are the best practices for creating tree diagrams?

- Defining the process for breaking down details at the start - Using no more than four items at any level - Not allowing groups or levels to merge - Training the leader of the exercise on how the process of creating a tree diagram works

What are the best practices for creating interrelationship digraphs?

- Ensuring idea cards are easily visible - Using a spacious work area - Enforcing team ground rules about behavior - Taking ideas from other exercises or sessions

What are the best practices for creating affinity diagrams?

- Having a team with 4-7 members - Encouraging team members to think outside the box - Ensuring team members share a basic understanding of the issue - Using a cross-functional team

What are the advantages of using tree diagrams?

- They encourage step-by-step thinking - They help effectively seek out and check process details - They clearly show how parts of a process are related - They're easy to interpret

What are the instances in which matrix diagrams would be used?

- To assign project tasks - To combine two tree diagrams into a single matrix - To determine causes and effects of issues - To show the potential of improvement efforts during the Improve stage

What are the possible uses for activity network diagrams?

- To communicate risks to stakeholders - To describe the flow of activities within a process - To discover ways to get a project done sooner - To serve as part of the communication plan

Why would you use an interrelationship digraph?

- To discover factors influencing a process issue - To explore root causes of problems - To determine cause-and-effect relationships - To evaluate relationships between ideas

In what instances would you use a process decision program chart?

- To deal with tight time constraints - To plan contingencies in case risks occur - To conduct risk analysis during planning - To develop countermeasures for potential problems

How would a prioritization matrix be used in a Six Sigma project?

- To determine the activities or steps that need the team's attention - To rank diverse items based on specific criteria - To assess issues that seem unclear - To achieve group consensus on priorities

In which situations would affinity diagrams be used when planning Six Sigma projects?

-Understanding unclear or complex issues - Developing group consensus - Organizing large volumes of data - Brainstorming possible solutions to issues

Place the five steps of creating a matrix diagram in the appropriate order.

1. Defining the objective and items to be related 2. Choosing the matrix type 3. Deciding how the relationships will be depicted 4. Completing the diagram 5. Analyzing the diagram

Place the steps for creating a process decision program chart in the appropriate order.

1. Determining and clarifying the objective and its main activities 2. Discovering any possible problems or risks related to each activity 3. Identifying countermeasures or contingency plans you can put in place for each problem or risk

Organize the steps for creating an activity network diagram in the correct order.

1. Gather information 2. Identify activities 3. Sequence activities 4. Stack concurrent activities 5. Add network lines

Place the steps of creating a prioritization matrix in the correct sequence.

1. Identifying the criteria and items 2. Listing items and criteria on the vertical and horizontal axes 3. Scoring each item per criterion and adding a weight for importance 4. Totaling the scores for each item
