CLBB study guide

CLBB · Work through your exam, one topic at a time.

The Certified Lean Six Sigma Black Belt (CLBB) is a professional credential for practitioners who lead improvement projects end to end: scoping a problem with sponsors, building a measurement system, analyzing variation, piloting and standardizing a solution, and handing control to the process owner. It suits quality engineers, continuous improvement specialists, operations and manufacturing leaders, and analysts who already hold a Green Belt or comparable project experience and want to take on larger, cross-functional work with statistical depth. The CLBB study guide has 8 sections and about 2,526 words.

01

Enterprise-wide Deployment and Lean Six Sigma Fundamentals

You must show that you understand Lean Six Sigma as a management system , not just a toolbox. Know the difference between Lean (flow, waste, speed, the seven wastes: overproduction, waiting, transport, overprocessing, inventory, motion, defects) and Six Sigma (variation reduction, DMAIC, statistics).

05

Measure Phase

Measure establishes a valid baseline : what the process does now, with trustworthy data. Deliverables: operational definitions, data collection plan, measurement system analysis (MSA), baseline capability, and a refined problem statement.

06

Analyze Phase

Analyze identifies and verifies root causes of the Y using data - not opinion. Deliverables: verified root causes (the vital few x's) and a data-supported cause-and-effect story.

307 words, about 2 min
07

Improve Phase

Improve selects, tests, and implements solutions that address verified root causes . Deliverables: prioritized solutions, a pilot, and an implementation plan with owners and dates.

282 words, about 1 min
08

Control Phase

Control locks in the gains. Deliverables: a control plan, updated standard work, monitoring (control charts), response plan, and project handoff/closure with documented lessons learned.
