Defining Success Criteria:
Establishing clear and measurable success criteria for process improvements.
Setting expectations and targets for validated results.

Data Collection and Measurement:
Collecting relevant data to assess the impact of process changes.
Choosing appropriate metrics and measurement methods.

Data Analysis Techniques:
Using statistical analysis to determine if improvements are statistically significant.
Identifying potential sources of variation.

Before-and-After Comparison:
Conducting a thorough comparison of process performance before and after changes.
Using control charts and visual tools for comparison.

Hypothesis Testing:
Applying hypothesis testing to validate the effects of process improvements.
Interpreting p-values and confidence intervals.

Stakeholder Validation:
Obtaining feedback and validation from stakeholders, including customers and process users.
Incorporating their perspectives into results assessment.

Control Plan Effectiveness:
Evaluating the effectiveness of control plans implemented during the Improve and Control phases.
Monitoring process stability.

Sustainability Assessment:
Determining the long-term sustainability of process improvements.
Assessing if improvements are maintained over time.

Root Cause Analysis of Variances:
Investigating any variations or discrepancies in results.
Identifying root causes and corrective actions if improvements are not validated.

Documentation and Reporting:
Documenting the results validation process.
Creating reports to communicate validated results to stakeholders.

Lean Six Sigma Tools for Validation:
Using Lean Six Sigma tools like Fishbone diagrams and Pareto charts to analyze validation data.
Demonstrations and practical exercises.
