Improve Phase (DMAIC) – Mind Map
Purpose of Improve Phase
Focus on developing solutions to eliminate validated root causes
Ensure solutions are data-driven and statistically validated
Test solutions on a small scale before full implementation
Prioritize solutions based on impact, feasibility, and cost
Solutions Selection Matrix
Includes problem statement and prioritized root causes
Encourages open brainstorming without early judgment
Built collaboratively with team members and stakeholders
Structured tool to evaluate and rank potential solutions
Evaluation Criteria
Feasibility evaluates effort, time, and resource requirements
Cost-benefit estimates financial value versus expected gains
Effectiveness measures how well solution removes root cause
Scoring Method
Assign ratings from 1 to 10 for each criterion
Multiply scores to determine overall priority
Select highest scoring solutions for implementation
Cost-Benefit Analysis
Includes both tangible and intangible benefits
Requires collaboration with finance or accounting teams
Compares implementation costs with expected financial gains
Types of Costs
Equipment, software, labor, training, and operational disruption
Types of Benefits
Increased revenue, cost savings, customer retention, morale improvement
Payback Analysis
Formula: Implementation Cost ÷ (Annual Benefits – Annual Costs)
Helps leadership evaluate financial viability quickly
Estimates time required to recover investment
Shorter payback periods are generally preferred
Net Present Value (NPV)
Uses a discount rate provided by finance teams
Positive NPV indicates financially beneficial project
Adjusts future cash flows for time and inflation
Provides more accurate long-term financial evaluation
Piloting a Solution
Reduces risk before full-scale implementation
Identifies unexpected issues and improvement opportunities
Conduct limited trial in real working environment
Benefits of Pilot
Allows feedback from real users
Confirms solution effectiveness before scaling
Minimizes resource waste and operational disruption
Pilot Approaches
Limited group, location, or timeframe testing
Alpha testing with small group, followed by broader beta testing
Analyzing Pilot Results
Apply hypothesis testing to validate improvements
Use visual charts to communicate results to leadership
Use statistical tools to compare before-and-after performance
Confirm measurable and positive impact
Implementation Planning
Assign tasks, deadlines, and accountability
Coordinate with internal teams and external stakeholders
Develop structured action plan with clear responsibilities
Documentation
Create standard operating procedures (SOPs)
Provide supporting materials like guides and FAQs
Maintain complete record of analysis, decisions, and changes
Ensure easy access for all relevant team members
Training
Ensure knowledge transfer across impacted teams
Integrate training into organizational learning systems
Train key personnel who will train others (train-the-trainer model)
Transition to Control Phase
Ensure monitoring and measurement systems are defined
Strengthen sustainability through documentation and training
Prepare process ownership handoff to business teams
Improve Phase Checklist
Data confirms effectiveness of implemented solutions
Cost-benefit analysis completed
Top solutions selected and tested on small scale
Leadership approval obtained
Solutions identified, evaluated, and prioritized
Documentation and training materials finalized
Staff trained and ready for full implementation
