In the journey of continuous improvement, organizations often find themselves at a critical juncture where identifying problems and analyzing root causes is only half the battle. The real challenge lies in implementing solutions and ensuring they become embedded within the organizational culture. This is where the Improve phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology intersects with robust change management principles, creating a powerful framework for sustainable transformation.
The Critical Connection Between Improvement and Change Management
Change management represents the systematic approach to dealing with transformation at both organizational and individual levels. Within the context of Lean Six Sigma’s Improve phase, change management principles become instrumental in bridging the gap between theoretical solutions and practical implementation. Without effective change management, even the most brilliant process improvements can face resistance, partial adoption, or complete failure.

Consider a manufacturing company that identified excessive downtime in their production line. After thorough analysis, the team proposed implementing a new predictive maintenance system. However, the technical solution alone would not guarantee success. The maintenance staff, accustomed to reactive repairs for fifteen years, needed to embrace a fundamentally different approach to their work. This scenario illustrates why understanding change management principles is not optional but essential for improvement initiatives.

Understanding Human Dynamics in Process Improvement
One of the most critical aspects of change management involves recognizing that processes do not change themselves; people change processes. Human behavior, emotional responses, and psychological resistance form the invisible barriers that can derail improvement efforts. Research consistently shows that approximately 70% of change initiatives fail, primarily due to employee resistance and lack of management support rather than technical inadequacies.
The Psychology of Resistance
Resistance to change emerges from various sources, including fear of the unknown, loss of control, concern about competence, and disruption of established routines. In the Improve phase, project teams must acknowledge these concerns rather than dismissing them as irrational obstacles. For example, when a customer service department transitions from manual call logging to an automated CRM system, employees may worry about their technical abilities, fear redundancy, or feel overwhelmed by additional training requirements.
A telecommunications company experienced this firsthand when implementing a new quality monitoring system. Initial resistance was significant, with customer service representatives viewing the system as invasive surveillance. However, by involving employees in the design process and clearly communicating how the system would help them improve their performance rather than punish mistakes, adoption rates increased from 45% to 92% within three months.
Fundamental Change Management Models for the Improve Phase
Kotter’s Eight-Step Change Model
John Kotter’s framework provides a structured approach particularly relevant to the Improve phase. The model emphasizes creating urgency, building guiding coalitions, developing clear visions, communicating extensively, removing obstacles, generating short-term wins, building on change, and anchoring changes in culture. These steps align seamlessly with improvement implementation strategies.
Take a healthcare facility that aimed to reduce patient wait times by 40%. They began by sharing data showing how current wait times compared unfavorably with competitor hospitals, creating urgency. They then assembled a cross-functional team including physicians, nurses, administrative staff, and patient advocates. This coalition developed a clear vision of streamlined patient flow, communicated through department meetings, visual displays, and regular updates. Within six months, wait times decreased by 43%, exceeding their target.
ADKAR Framework
The ADKAR model (Awareness, Desire, Knowledge, Ability, Reinforcement) focuses on individual change, making it highly applicable when implementing process improvements. Each element must be addressed sequentially for successful change adoption.
A financial services company applying ADKAR during their Improve phase achieved remarkable results. When implementing a new loan processing system, they ensured employees understood why change was necessary (Awareness), addressed individual concerns about job security (Desire), provided comprehensive training programs (Knowledge), offered hands-on practice sessions with coaching (Ability), and established recognition programs for early adopters (Reinforcement). Processing times improved by 35%, and error rates decreased from 8.2% to 2.1% within four months.
Practical Application: Integrating Change Management into the Improve Phase
Stakeholder Analysis and Engagement
Effective change management begins with comprehensive stakeholder analysis. Project teams must identify everyone affected by proposed improvements, assess their influence and interest levels, and develop tailored engagement strategies. A stakeholder matrix categorizes individuals or groups into four quadrants: high power/high interest, high power/low interest, low power/high interest, and low power/low interest.
For instance, when a retail chain implemented a new inventory management system across 150 stores, they identified store managers as high power/high interest stakeholders. Regional directors were high power with varying interest levels. Store associates were low power but high interest. The project team developed distinct communication and involvement strategies for each group, resulting in smooth implementation with minimal disruption.
Communication Strategy Development
Communication serves as the lifeblood of successful change initiatives. During the Improve phase, teams must develop comprehensive communication plans addressing what information to share, with whom, when, how, and through which channels. Effective communication is bidirectional, allowing concerns and feedback to flow upward as readily as directives flow downward.
A logistics company exemplified this approach when implementing route optimization software. They established weekly town halls, created an anonymous feedback mechanism, published weekly progress newsletters, and designated change champions within each team. Open communication channels helped identify and resolve implementation challenges quickly, such as GPS accuracy issues in rural areas that the project team had not anticipated.
Measuring Change Management Effectiveness
Like any aspect of Lean Six Sigma, change management requires measurement and monitoring. Key performance indicators for change management during the Improve phase might include adoption rates, time to proficiency, employee satisfaction scores, turnover rates among affected groups, and feedback sentiment analysis.
Consider this sample dataset from a manufacturing improvement project:
Week 1 Post-Implementation: Adoption rate 38%, average proficiency score 4.2/10, employee satisfaction 5.1/10, voluntary process compliance 41%
Week 4 Post-Implementation: Adoption rate 67%, average proficiency score 6.8/10, employee satisfaction 6.7/10, voluntary process compliance 71%
Week 8 Post-Implementation: Adoption rate 89%, average proficiency score 8.3/10, employee satisfaction 7.9/10, voluntary process compliance 94%
This data demonstrates the typical adoption curve and highlights the importance of sustained change management efforts beyond initial implementation. The organization maintained intensive support through week six, which correlated with accelerated adoption and proficiency gains.
Overcoming Common Implementation Challenges
Addressing the Knowing-Doing Gap
Organizations frequently encounter the knowing-doing gap, where employees understand new processes intellectually but struggle with practical application. Bridging this gap requires hands-on training, simulation exercises, job aids, coaching, and tolerance for initial performance dips.
A hospital implementing a new patient handoff protocol experienced this challenge. Despite training sessions, compliance remained below 60% after three weeks. The improvement team then introduced bedside coaching, shadow shifts with experienced practitioners, and quick-reference cards attached to ID badges. Compliance rose to 88% within two additional weeks, and patient safety incidents related to communication gaps decreased by 53%.
Sustaining Momentum
Initial enthusiasm often wanes as implementation extends over time. Change fatigue sets in, competing priorities emerge, and attention shifts elsewhere. Sustaining momentum requires celebrating quick wins, maintaining visible leadership support, refreshing communication approaches, and connecting improvements to meaningful outcomes.
When an educational institution implemented a new student advising system, they celebrated milestones publicly: first 100 students processed, first week with zero errors, first month of sustained performance. They shared success stories highlighting how the new system helped specific students. These efforts maintained engagement through a six-month implementation period, ultimately achieving their goal of reducing advising appointment times by 30% while improving student satisfaction ratings.
Building a Change-Ready Culture
While individual improvement projects benefit from change management principles, the ultimate goal involves cultivating a change-ready organizational culture. Such cultures view change as opportunity rather than threat, embrace continuous learning, encourage experimentation, and maintain psychological safety where people feel comfortable voicing concerns or suggesting improvements.
Organizations with mature change management capabilities integrate these principles into every improvement initiative automatically. Their employees expect involvement in problem-solving, anticipate regular process evaluations, and possess skills to adapt to new methods quickly. This cultural foundation dramatically increases the success rate of improvement initiatives and accelerates benefit realization.
Conclusion: The Path Forward
Understanding and applying change management principles during the Improve phase transforms how organizations implement process enhancements. Technical solutions address what needs to change, while change management addresses how people will adopt, sustain, and embrace those changes. Together, they form a comprehensive approach to organizational improvement that delivers measurable results and builds lasting capability.
Success in modern business environments demands more than process excellence; it requires the ability to implement change effectively, repeatedly, and with minimal disruption. Leaders and practitioners who master change management principles alongside technical improvement methodologies position themselves and their organizations for sustained competitive advantage.
The integration of change management with Lean Six Sigma methodology represents a powerful combination that addresses both the technical and human dimensions of improvement. As you advance your understanding of these principles, you will find that successful improvement initiatives depend less on the brilliance of solutions and more on the effectiveness of implementation.
