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

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.

> Why it is done
> Where it is done
> When it is done

> 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

> Defective or not defective is an example of attribute data, not variable data.
> The utilization of a smaller sample size is a component of a variable sampling plan.
Each unit can be weighted by its proximity to specifications in a variable sampling, whereas for attribute data all defectives are equal.
> The inspection method is a component of a variable sampling plan because each item has a measurement, as opposed to attribute data where go/no-go gages are employed.

Answer

> Storage is a type of waste associated with space. Value stream mapping can be used to identify such waste.
> Scrap is a type of waste in materials.
> Requiring too many permissions is an example of complexity waste.
> A production that requires moving parts from the warehouse to a staging area, then to the production floor for assembly is an example of transportation waste (movement) that may not add value.

Answer

> Project selection criteria aligned with the mission of the organization and its related quality, service, and cost goals is the correct answer.
> Organizational goals should be used to identify valuable Six Sigma projects to be launched for key processes that support the goals.
> Organizational goals should be used to identify valuable Six Sigma projects to be launched for key processes that support the goals.
> Setting goals based simply on the process in question can sub-optimize the organization.
> Six Sigma projects being identified as process output measures that are used to establish broader goals for the organization is a backward response. Without consideration of organizational goals, a Six Sigma project may pick goals that are inappropriate or that have an adverse impact on the organization.

Answer

Look up the answer using a z table. We need to find the percent above and below 4 standard deviations. The z table number for 4.0 is 0.000032. Multiply this number by 2 because there are 2 tails. This gives .000064. Change to ppm by multiplying by 1,000,000. = 64ppm

Answer

The Kano model is useful in gaining a thorough understanding of a customer's needs. Quality Function Deployment (QFD) integrates customer requirements (voice of the customer, or VOC) into the design and delivery of a service offering, but these requirements need to be collected first using other methods.

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

As with identifying needs, capturing customer feedback is important. However, unless the feedback is acted upon in a meaningful way, it will not promote customer satisfaction. Quality and product features are important, but there are other considerations such as providing unnecessary features, value for the price, etc... The ability of a product or service to meet the needs of a user or purchaser is the correct answer.

‥ The passport authority is a supplier to the post offices
‥ The post offices are external customers for the passport authority

Answer

Value stream mapping is used for analyzing waste and value-added processes.

Answer

We can identify physical inefficiencies by converting a flow chart to a work-flow diagram. Deployment flow chart shows who performs which step. SIPOC focuses on input, process, and output.

Answer

The shape of the distribution is key, since it determines what statistics are used to describe the distribution. Not all distributions use the same descriptive statistics (Weibull distributions, exponential distributions, etc. do not use the standard deviation).
