In the world of continuous improvement, the Improve phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology represents a critical turning point where analysis transforms into action. While data and statistical tools provide the foundation, the true catalyst for sustainable change lies in employee involvement. Organizations that harness the collective intelligence and experience of their workforce during this phase consistently achieve superior results compared to those that rely solely on management-driven initiatives.
Understanding the Improve Phase in Lean Six Sigma
The Improve phase follows a systematic journey through problem definition, measurement, and analysis. At this stage, teams have identified root causes and are ready to develop, test, and implement solutions. However, the transition from identifying problems to implementing effective solutions requires more than technical expertise. It demands the active participation of those who understand the work most intimately: the employees who perform it daily.

Research from the American Society for Quality indicates that organizations with high employee engagement in improvement initiatives report 23% higher profitability and 18% higher productivity than their counterparts. These statistics underscore a fundamental truth: improvement efforts succeed or fail based on the people implementing them.

Why Employee Involvement Matters in Solution Development
Frontline Knowledge and Practical Insights
Employees working directly with processes possess invaluable tacit knowledge that data alone cannot reveal. They understand the nuances, workarounds, and contextual factors that influence process performance. When developing solutions during the Improve phase, this frontline intelligence helps teams avoid theoretical fixes that sound good on paper but fail in practice.
Consider a manufacturing facility experiencing high defect rates in their assembly line. Data analysis revealed that defects spiked during shift transitions. While management initially proposed standardized handover procedures, line workers identified that the real issue stemmed from inconsistent lighting conditions at different times of day, which affected quality inspection accuracy. This insight, which only emerged through employee involvement, led to a lighting system upgrade that reduced defects by 34% over six months.
Increased Buy-In and Reduced Resistance
Solutions developed collaboratively with employees naturally enjoy greater acceptance during implementation. When people contribute to creating change, they develop ownership and commitment to its success. Conversely, imposed solutions often encounter passive resistance, regardless of their technical merit.
A healthcare organization implementing a patient intake process improvement demonstrates this principle effectively. Their initial project team consisted solely of administrative managers who designed a new electronic intake system. Despite its efficiency gains on paper, adoption remained below 40% after three months. After reconvening the team to include registration clerks, nurses, and patient representatives, they redesigned the solution to address practical concerns about screen navigation, patient privacy during data entry, and integration with existing workflows. Adoption rates climbed to 87% within two months of implementing the revised solution.
Practical Strategies for Engaging Employees in the Improve Phase
Structured Brainstorming Sessions
Effective brainstorming requires structure and psychological safety. Facilitate sessions where employees at all levels can contribute ideas without judgment. Use techniques such as brainwriting, where participants write ideas independently before sharing, to ensure quieter team members have equal voice. Document all suggestions and explain how each will be evaluated against project criteria.
During a logistics company’s initiative to reduce delivery delays, structured brainstorming sessions with drivers, dispatchers, and warehouse staff generated 47 potential solutions. The team evaluated these using a prioritization matrix based on impact, feasibility, and cost. The top five solutions, including route optimization software integrated with real-time traffic data and a revised loading sequence protocol, were tested through pilot programs.
Pilot Testing with Employee Feedback Loops
Rather than full-scale implementation, conduct pilot tests that allow employees to experience proposed solutions and provide structured feedback. This iterative approach identifies unforeseen issues and builds confidence in the final solution.
A financial services company tested a new customer service workflow with one team of ten representatives before enterprise-wide rollout. During the three-week pilot, daily feedback sessions captured 23 adjustment needs, ranging from script modifications to system integration improvements. The refined solution achieved a customer satisfaction increase of 28 percentage points and reduced average handling time by 90 seconds per call, versus the 15 percentage point increase and 45-second reduction projected from the original design.
Cross-Functional Improvement Teams
Solutions often impact multiple departments, making cross-functional representation essential. Include employees from upstream and downstream processes to ensure comprehensive solution design. This diversity prevents optimizing one area at another’s expense.
An example from a food processing plant illustrates this approach. Their quality improvement team initially included only quality assurance staff. Solutions focused on additional inspection checkpoints, which would have increased production time by 12%. By expanding the team to include production operators, maintenance technicians, and supply chain coordinators, they developed an integrated solution combining improved supplier specifications, enhanced equipment calibration procedures, and streamlined inspection protocols. The comprehensive approach improved quality by 31% while actually reducing cycle time by 4%.
Real-World Application: A Detailed Case Study
A mid-sized electronics manufacturer faced persistent inventory accuracy issues affecting order fulfillment. Their DMAIC project reached the Improve phase with clear data showing that inventory discrepancies averaged 8.3% across all product categories, causing shipment delays and customer complaints.
Employee Involvement Approach
The improvement team conducted focus groups with warehouse personnel, inventory clerks, purchasing staff, and sales representatives. Employees identified several root causes that data analysis had missed, including unclear bin labeling conventions, inconsistent counting procedures across shifts, and communication gaps when products were transferred between storage locations.
Collaborative Solution Development
Working together, employees and project leaders designed a multi-faceted solution including standardized labeling with visual cues, a simplified counting procedure documented with employee-created visual work instructions, a mobile scanning system for real-time inventory updates, and a brief shift-overlap period for physical handoffs of in-process transfers.
Results and Sustainability
After implementation, inventory accuracy improved to 97.2% within four months. More importantly, the solutions remained effective because employees had designed them to fit their work reality. Annual customer complaints related to order errors decreased by 64%, and the company avoided an estimated $340,000 in costs related to expedited shipping, emergency purchases, and customer concessions.
Measuring Employee Involvement Effectiveness
Quantifying the impact of employee involvement helps justify continued investment in participative approaches. Track metrics such as number of employee-generated ideas implemented, time from solution design to full adoption, employee satisfaction scores related to change initiatives, and sustainability of improvements over time.
Organizations with mature employee involvement practices typically see 60-70% of implemented solutions originating from frontline employees, compared to 20-30% in organizations with limited employee engagement. Additionally, improvements with high employee involvement demonstrate 40% better long-term sustainability rates.
Overcoming Common Barriers
Several obstacles frequently hinder employee involvement. Time constraints make participation challenging when employees struggle to balance improvement activities with regular responsibilities. Address this by scheduling dedicated improvement time and ensuring adequate staffing coverage. Lack of confidence in sharing ideas often stems from past experiences where suggestions went unheard. Build trust by visibly acting on employee input and explaining decisions when suggestions cannot be implemented. Skill gaps in problem-solving methodologies can limit contribution quality, making training in basic improvement tools valuable for all staff.
Building a Culture of Continuous Involvement
Effective employee involvement during the Improve phase does not happen by accident. It requires intentional culture building supported by leadership commitment, recognition systems that celebrate contribution, transparent communication about improvement priorities and results, and accessible training in improvement methodologies.
Organizations that excel in this area treat every improvement project as both a solution development effort and a capability building opportunity. They invest in developing employee problem-solving skills, creating more capable contributors for future initiatives while solving current challenges.
Conclusion
The Improve phase represents the bridge between analysis and results in Lean Six Sigma initiatives. While technical tools and statistical methods provide important guidance, sustainable solutions emerge from genuine collaboration with the employees who understand work processes most deeply. Organizations that embrace participative approaches during improvement efforts consistently achieve better results, faster adoption, and longer-lasting change.
Success in the Improve phase requires more than inviting employee participation. It demands structured methods for capturing input, pilot testing approaches that incorporate feedback, cross-functional collaboration, and genuine commitment to acting on employee insights. When organizations get this right, they unlock innovation potential that transforms both performance and culture.
The evidence is clear: improvement initiatives that actively engage employees deliver superior results across all measures that matter including implementation speed, solution effectiveness, cost efficiency, and long-term sustainability. In an era where competitive advantage increasingly depends on operational excellence, mastering employee involvement in the Improve phase is not optional but essential.
