Quiz 5- Root Cause Analysis and Improvement

What is the purpose of Root Cause Analysis? *

To identify underlying reasons rather than only symptoms

To calculate ROI

To define project closure

To select a belt level

Which technique repeatedly asks why to drill down toward an underlying cause? *

5 Whys

Kanban

CUSUM

Kappa

Which tool is also known as the Ishikawa diagram? *

Fishbone diagram

Control Plan

RACI matrix

Box plot

A recurring equipment problem is traced to the absence of a preventive maintenance schedule. What has been identified? *

A project charter

A potential root cause

A financial benefit

A sampling method

What does FMEA systematically evaluate? *

Employee attendance

Project celebration

Customer advertising

Potential failures, effects and risks

What does FMEA stand for? *

Financial Measurement and Evaluation Analysis

Failure Modes and Effects Analysis

Flow Mapping and Efficiency Analysis

Functional Monitoring and Escalation Assessment

What is the purpose of RPN scoring in FMEA? *

To help prioritize risks

To calculate project ROI

To define process ownership

To select a sampling method

Why are risk values used in FMEA? *

To prioritize attention to higher-risk issues

To eliminate documentation

To replace root cause analysis

To calculate employee productivity

What does Six Thinking Hats provide? *

Multiple perspectives for examining an issue and supporting divergent thinking

A method for calculating control limits

A sampling strategy

A financial accounting method

Which area can Six Thinking Hats support? *

Creativity and innovation

Measurement calibration only

Financial auditing only

Process ownership only

When might Six Thinking Hats be useful? *

When a team is stuck in the same perspective

When no issue exists

Only after project closure

Only for calculating ROI

What is the purpose of a pilot implementation? *

To eliminate all project risks

To test an improvement on a limited scale

To close the project immediately

To replace the Control Plan

What is a key benefit of piloting an improvement? *

It allows evaluation and identification of issues before wider implementation

It guarantees zero defects

It eliminates the need for measurement

It removes stakeholder involvement

An improvement is first implemented in one production area before plant-wide rollout. What is this? *

Project closure

Pilot implementation

FMEA scoring

Control documentation

What is the purpose of Poka-Yoke? *

To prevent errors or make them detectable

To calculate ROI

To compare group means

To define project scope

Which approach is an example of error prevention? *

Designing a process so an incorrect action cannot easily occur

Waiting until defects reach the customer

Removing process controls

Ignoring operator feedback

A component is designed to fit only in the correct orientation. What concept is illustrated? *

ANOVA

Poka-Yoke

CUSUM

SIPOC

Which sequence best represents Section 5? *

RCA → FMEA → Six Thinking Hats → Pilot → Poka-Yoke

DOE → Closure → CAPA → ROI → VSM

Charter → Sampling → ANOVA → Control → Handover

Kappa → Regression → Kanban → ROI → Closure

Which combination represents an integrated Section 5 improvement approach? *

Identify causes and risks, develop alternatives, pilot improvements and prevent errors

Calculate ROI, close the project and remove controls

Map roles, calculate capability and celebrate

Select a distribution, create a charter and hand over the process

What is the overall purpose of the Section 5 sequence? *

Identify causes and risks, develop alternatives, test improvements and prevent errors

Only calculate project financial benefits

Only perform statistical testing

Only document project closure
