Question 1

The ideal state of processes is one in which products and services proceed through each stage at the rate required by customers. This indicates that there aren't any process bottlenecks or other types of waste.

Accepted Answer

Flow

Answer

In Lean Six Sigma, 'Flow' refers to the continuous, uninterrupted movement of products, services, or information through a process at the rate required by the customer. This concept is central to eliminating waste, such as waiting and bottlenecks, and achieving optimal efficiency. The ideal state described perfectly aligns with the principle of continuous flow.

Question 2

The process of producing several units of a specific item in order to achieve financial efficiency.

Accepted Answer

Batching

Answer

Batching is the practice of producing several units of a specific item together in a group, often to achieve economies of scale or reduce setup times. While it can be done for financial efficiency, in Lean principles, large batches are often considered a form of waste (e.g., inventory, waiting) if they disrupt continuous flow. The definition directly describes the concept of batching.

Question 3

Using the presumption that each test will provide the opportunity for crucial fine tuning, Dr. Deming devised a process that prioritizes trial and error over lengthy planning and aiming for perfection up front. Frequently used in conjunction with A3 Documentation.

Accepted Answer

PDCA (aka Plan Do Check Adjust)

Answer

The PDCA cycle (Plan-Do-Check-Act/Adjust) is a continuous improvement model developed by Dr. Deming. It emphasizes iterative learning through small-scale experiments, allowing for rapid testing, evaluation, and adjustment, rather than striving for perfection in initial planning. This approach of trial and error with crucial fine-tuning aligns perfectly with the description provided.

Question 4

The phrase "________________" in relation to a Design of Experiments refers to variables that are a linear combination of one another.

Accepted Answer

Collinear

Answer

In the context of Design of Experiments (DOE) and regression analysis, 'collinear' variables are those that are highly correlated and can be expressed as a linear combination of one another. This condition, known as multicollinearity, can complicate the analysis by making it difficult to determine the independent effect of each variable on the response.

Question 5

Which statement(s) about fractional factorial designs are false?

Accepted Answer

Resolution V design is desired while controlling the costs of experimentation

Answer

While a Resolution V design is highly desirable in fractional factorial experiments because it allows main effects and two-factor interactions to be estimated without being aliased with each other, achieving higher resolution typically requires more experimental runs. More runs mean increased cost of experimentation, not controlling or reducing it. Therefore, the statement that Resolution V controls costs is false in the context of minimizing experimental runs.
