Six Sigma Lean Green Belt Certification: Learn DMAIC

Provide vision and leadership to guide the Lean Six Sigma project to success. Organize workshops, sustain momentum, engage stakeholders, and maintain thorough documentation.

Activate the activity team to bring core expertise and collaborate with the champion. Allocate time with the sponsor, contribute expertise, complete tasks, and keep the champion informed toward goals.

The process owner aligns projects with organizational goals, securing resources and budgets. Prepare the project charter, establish a monitoring framework, and drive gate reviews and KPI targets.

Mentor and coach initiative champions, process owners, and activity teams on Lean Six Sigma; guide scoping and DMAIC use, and review closure reports during gate reviews to ensure project integrity.

Executive sponsors drive the dmaic project's success with oversight, resources, and stakeholder management as the escalation point, aligning with objectives and prioritizing improvements, impact measurements, and deliverables.

Leverage subject matter experts to supply domain-specific insights, engage in cause-and-effect diagramming and process mapping, and help the team develop innovative solutions and resolve technical challenges.

Apply lean six sigma to hospital emergency department triage, using DMAIC, SIPOC, and Gemba Walks to cut wait times and boost patient satisfaction.

Define phase kicks off the DMAIC process and defines the problem, scope, goals, and objectives for lean six sigma projects, with charter, voice of the customer, and SIPOC guiding stakeholders.

Capture the voice of both internal and external customers to ensure value delivery by using surveys, one-on-one discussions, customer service interactions, focus groups, and data analysis to uncover CTQ factors.

Explore the SIPOC diagram, with suppliers, inputs, process, outputs, and customers, and learn how it defines project scope in the Six Sigma define phase to minimize waste and defects.

Learn to measure process performance in the DMAIC cycle by establishing KPIs, gathering reliable data, creating baselines, mapping workflows, and applying gage R&R and data analysis tools.

Visualize data with charts and graphs to reveal patterns and trends in lean six sigma projects. Use pie, Pareto, line graph, run chart, and histograms to identify distribution and outliers.

Engage stakeholders to verify data collection, ensure a complete process map and reliable measurement systems, update the charter, and identify quick wins for an accurate, transparent measure gate review.

Identify root causes in the analyze phase of lean six sigma by analyzing data to uncover inefficiencies and move from symptoms to root causes for focused improvements.

Use the fishbone diagram, or Ishikawa diagram, to identify and visually map the potential causes of a problem, organized into 6M categories: people, process, equipment, materials, environment, and management.

Apply the five why’s technique to uncover root causes by repeatedly asking why, peeling back layers from symptoms to core issues, as demonstrated by the memorial example.

Brainstorm and map all identified causes with the fishbone, analyze with the 5 whys, then apply the CNX technique to constant, noise, and variable factors to identify root causes.

Identify and validate vital root causes, confirm the as-is process, review non-value-added analysis and statistical analyses, update stakeholders, adapt the communication plan, and inform the next DMAIC steps.

Identify and test solutions to root causes in the improve phase, using creativity to optimize processes and achieve better outcomes through actionable improvements.

Sort, set in order, shine, standardize, and sustain a safer, more efficient workplace. Apply the red tag process and 5S audits to drive continuous improvement and eliminate waste.

Learn to implement poka-yoke to eliminate defects before they occur through manual and technical fault detection, jidoka integration, and four fault-prevention levels, illustrated by ATMs in banking.

Explore creativity techniques in the improve phase to generate improvement ideas from root causes, including brainstorming, anti-solution approach, brainpool writing, and brainsketching, fostering collaboration and testing in later stages.

Utilize the effort-benefit matrix to prioritize projects by impact versus effort, categorizing tasks into quick wins, strategic investments, low-priority, and resource drains to maximize efficiency and value.

See how Lean Six Sigma in the control phase reduces stockouts by establishing monitoring systems, SOPs for reordering, staff training, and control charts to promptly identify stock level shortfalls.

Conduct a control gate review to verify that control measures are implemented and functioning, and confirm updated process documentation with a plan for ongoing monitoring to sustain performance.

Master the DMAIC framework and Lean Six Sigma tools to lead projects and foster a culture of continuous improvement, collaboration, and innovation for operational excellence.
