Question 1

A manager of an agile team was asked by a project sponsor to compile the lessons learnt. Which of the following statements most accurately describes this circumstance?

The manager should collect the lessons learned throughout the project.
The manager should collect the lessons learned only at the end of the project
The manager should collect the lessons learned only when the project performance is not good
The manager should collect the lessons learned only when the project performance is not good

Accepted Answer

Lessons learned should be captured throughout the project when the details are fresh and team members can remember the most detail. Also this allows lessons learned early in the project to inform later phases.

Answer

Lessons learned should be captured continuously throughout the project so details are recorded while still fresh and team members can recall them accurately. This also lets insights gained early inform later phases, supporting agile's continuous-improvement philosophy. Waiting until the end—or only logging them when performance is poor—loses valuable detail and misses the chance to improve as you go.

Question 2

On a written process or work instruction, which of the following is frequently described?

Procedure: What ,Why; Work instruction: Who, How, When, Where
Procedure: What ,Why, Who, How; Work instruction: When, Where
Procedure: What, When, Where, Who; Work instruction: How , Why
Procedure: What, Why, When, Where; Work instruction: Who, How.

Accepted Answer

Procedures are written to describe:
> What is done during the process
> Why it is done
> Where it is done
> When it is done
> Work instructions explain two other important aspects:
> Who does what
> How it is done
> Who does what" is the main concept of work instruction.
> Usually "when and where "are considered in a procedure.

Answer

A procedure describes the high-level what, why, when, and where of a process, while a work instruction provides the detailed who and how of carrying it out. The key distinction is that 'who does what' and 'how it is done' belong to work instructions, whereas timing and location are covered at the procedure level.

Question 3

When rating a service, respondents are given the options of poor, fair, good, very good, or outstanding. What kind of measurement scale does this serve as an example of?

Accepted Answer

Ordinal

Answer

Ordinal scales are valuable when it is difficult or impractical to establish exact numerical measurements, but you still want to capture respondents' preferences or perceptions in a ranked order. They provide valuable insights into the relative ranking or preference of items without requiring respondents to assign specific numerical values. However, when it comes to performing statistical analyses, ordinal data has limitations, as it lacks equal intervals between categories, and arithmetic operations like addition or subtraction are not meaningful. Therefore, it's crucial to use appropriate statistical methods when working with ordinal data.

Question 4

Which Six Sigma function is most likely to respond if a specific circumstance in a company calls for the elimination of organizational barriers and making sure the team has the right resources?

‥ Champion
‥ Process Owner
‥ Change agent
‥ Black Belt

Accepted Answer

The main responsibilities of a Champion are to remove roadblocks and ensure the team has needs resources.
Process owners can make changes only within their processes. Change agent is another designation for the Black Belt does not include authority to remove roadblocks.

Answer

The Champion is responsible for removing organizational barriers and securing the resources a team needs, giving them the authority to clear roadblocks across the organization. A Process Owner can only make changes within their own process, and a Change Agent (often the Black Belt) leads improvement work but lacks the authority to remove organizational obstacles.

Question 5

On machine #7, a total of 4000 closures were produced. Each of the 200 closures had one flaw. 3800 closures in all were crowded. What are the throughput yield and defects per unit (DPU)?

‥ 1.05 DPU and 95% throughput yield
‥ 1 DPU and 99% throughput yield
‥ 0.05 DPU and 95% throughput yield
‥ 0.0526 DPU and 94.7% throughput yield

Accepted Answer

DPU is determined by 200/4000 = 0.05 and throughput yield is determined by 1.00 - 0.05 = .95 x 100 = 95% Defects per unit (DPU) is determined by the total number of defects divided by the total number of products produced in some time period. Throughput yield is determined by 1- % of closure defects * 100.

Answer

DPU is total defects divided by total units: 200 defects ÷ 4000 units = 0.05 DPU. Throughput yield is 1 − DPU = 0.95, or 95%. The other options miscalculate the ratio or confuse the relationship between defects and yield.
