Quiz 6- Design of Experiments

What is the purpose of DOE? *

To systematically study the effects of multiple factors on a process outcome

To document project closure

To assign belt responsibilities

To calculate customer satisfaction

What should a DOE strategy define? *

Objectives, factors, levels and responses

Only project cost

Only team members

Only the final celebration

Which design studies multiple factors systematically? *

RACI matrix

Factorial design

Control Plan

SIPOC

Why can randomized experimental runs be useful? *

They eliminate the need for factors

They replace data analysis

They support a structured strategy and reduce the influence of run order

They guarantee an optimum

A chemical plant studies temperature and pressure effects on yield. What methodology fits? *

DOE

RACI

CAPA

Control Plan

What is a factorial experiment designed to study? *

Multiple factors simultaneously

Only one observation

Only project financials

Only stakeholder roles

What important information can factorial experiments reveal? *

Interactions between factors

Project ownership

Document versions

Customer names

What does a full factorial design include? *

All combinations of the selected factor levels

Only one combination

Only the highest level

Only a baseline run

What does a fractional factorial design use? *

A subset of the possible combinations

Every possible combination

No experimental runs

Only historical data

A 2×2 experiment studies welding speed and electrode setting. What can it help reveal? *

Whether the factors interact

Which employee owns the process

Whether the project should close

The financial ROI automatically

What is a major purpose of DOE analysis? *

To identify significant factors and optimal settings

To define project scope

To document handover

To assign belt levels

What does optimization seek? *

The largest project team

The best combination of settings for the desired outcome

The longest process time

The highest documentation volume

Which statistical method is identified as a DOE analysis tool? *

RACI

Kappa

ANOVA

Which method is identified for optimization? *

RACI

Response Surface Methodology (RSM)

SIPOC

Gage R&R

How can regression support DOE optimization? *

By helping identify settings associated with an optimized process outcome

By assigning project roles

By documenting SOP ownership

By measuring categorical agreement

What is the purpose of a confirmation experiment? *

To replace the original experiment

To validate the predicted improvement in practice

To calculate belt-level responsibilities

To close the project without evidence

Which activities can support confirmation? *

Replication runs, control charts or hypothesis testing as appropriate

Only project celebration

Only stakeholder interviews

Only financial accounting

What should actual confirmation results be compared with? *

The prediction and acceptance criteria

Only the project title

Only the team roster

Only the original meeting schedule

Why is baseline performance important in DOE improvement work? *

It provides a reference for evaluating improvement

It replaces confirmation testing

It eliminates factor selection

It defines stakeholder roles

Which sequence best represents the DOE improvement flow? *

Close → Handover → Optimize → Define → Sample

Sample → Charter → CAPA → Celebrate → Optimize

Optimize → Predict → Confirm → Evaluate → Implement

RACI → 5S → Kappa → ROI → Closure
