Implementing process improvements is one thing; sustaining them over time is an entirely different challenge. Organizations worldwide invest significant resources in improvement initiatives, only to watch them gradually dissolve back into old patterns. The Sustain phase, the final step in methodologies like Lean Six Sigma and 5S, represents the critical juncture where lasting change either takes root or withers away. Understanding how to handle resistance during this phase can mean the difference between transformational success and disappointing regression.
Understanding Resistance in the Sustain Phase
Resistance during the Sustain phase manifests differently than initial implementation resistance. While early resistance often stems from fear of the unknown, sustain-phase resistance emerges from fatigue, complacency, and the gravitational pull of established habits. Employees may have initially embraced changes enthusiastically, only to find maintaining new standards exhausting or inconvenient over extended periods.

Research conducted across manufacturing organizations reveals that approximately 70% of improvement initiatives fail to sustain results beyond the first year. This statistic underscores the importance of developing robust strategies specifically designed to address long-term resistance patterns.

Common Forms of Resistance During Sustain Phase
Passive Resistance
This subtle form of resistance proves particularly challenging because it operates beneath the surface. Employees might attend required audits and training sessions while quietly reverting to old methods when supervision decreases. For example, a production team at a mid-sized electronics manufacturer initially reduced setup times from 45 minutes to 22 minutes through standardized work procedures. However, six months later, setup times had crept back to 38 minutes as workers gradually abandoned the new protocols without formal complaints or visible pushback.
Vocal Opposition
Some team members express resistance openly, questioning the continued value of maintaining new standards. Comments like “We tried this, and it worked at first, but it does not fit our current situation” or “This takes too much time for minimal benefit” signal active resistance that requires direct engagement.
Organizational Drift
As priorities shift and new initiatives emerge, earlier improvements receive diminishing attention from leadership. This organizational drift creates an environment where sustaining previous gains becomes increasingly difficult, regardless of individual commitment levels.
Root Causes of Sustain Phase Resistance
Initiative Fatigue
When organizations launch multiple improvement initiatives simultaneously or in rapid succession, employees experience mental and physical exhaustion. A distribution center case study documented that workers involved in three concurrent improvement programs showed 43% higher resistance rates during sustain phases compared to those focused on a single initiative.
Insufficient Recognition Systems
Initial improvements often receive celebration and recognition, but maintaining those improvements rarely generates equivalent acknowledgment. This recognition gap diminishes motivation to continue adhering to new standards.
Inadequate Support Structures
Teams may lack the tools, training refreshers, or leadership support necessary to maintain improvements long-term. Without proper infrastructure, even well-intentioned employees struggle to sustain changes.
Proven Strategies for Overcoming Resistance
Implement Robust Monitoring Systems
Effective monitoring systems provide visibility into performance trends before significant regression occurs. A pharmaceutical packaging facility implemented weekly trend charts tracking five key metrics related to their 5S implementation. By reviewing these charts during brief team huddles, they identified a 12% decline in sorting compliance within two weeks of its emergence, allowing immediate corrective action rather than discovering major regression months later.
The monitoring system included the following data points measured weekly:
- Sort compliance rate: Target 98%, Acceptable range 95-100%
- Set in order accuracy: Target 99%, Acceptable range 97-100%
- Shine audit scores: Target 95%, Acceptable range 92-100%
- Standardization adherence: Target 96%, Acceptable range 93-100%
- Sustain participation rate: Target 100%, Acceptable range 95-100%
When any metric fell below the acceptable range for two consecutive weeks, the system triggered a structured problem-solving session involving frontline workers and supervisors.
Create Meaningful Accountability Structures
Accountability extends beyond simple compliance checks. Effective accountability involves shared ownership where team members understand their role in collective success. A food processing plant established peer accountability teams of five to seven members who rotated monthly audit responsibilities. This structure increased sustain-phase compliance from 76% to 94% over six months because employees felt accountable to colleagues rather than simply following management directives.
Develop Comprehensive Training Refresher Programs
Skills and understanding erode over time without reinforcement. Organizations achieving superior sustain-phase results typically implement quarterly refresher training that goes beyond simple reminders. These sessions incorporate:
- Review of the original problem and improvement rationale
- Data showing current performance versus baseline
- Hands-on practice of key procedures
- Open discussion forums addressing emerging challenges
- Recognition of individuals demonstrating excellent adherence
Address Resistance Through Direct Engagement
When resistance appears, immediate and respectful engagement proves essential. A healthcare clinic experiencing resistance to new patient intake procedures scheduled one-on-one conversations between the department manager and each resistant staff member. These conversations, structured around understanding rather than correction, revealed that the resistance stemmed from confusion about two specific procedural elements rather than opposition to the overall change. Clarifying these elements resolved 80% of the resistance within one week.
Integrate Improvements into Standard Operating Procedures
Improvements that remain separate from standard operations face higher resistance over time. Successful organizations embed sustain-phase practices directly into job descriptions, performance evaluations, onboarding processes, and operational documentation. This integration transforms improvements from special initiatives into standard expectations.
Building a Sustain-Focused Culture
Long-term success requires cultivating an organizational culture that values consistency and continuous improvement equally. This culture develops through:
Leadership Modeling
Leaders must visibly participate in sustain-phase activities, attend audits, and reference sustained improvements in communications. When a plant manager at an automotive parts manufacturer began personally conducting monthly gemba walks focused specifically on sustained improvements, department-level compliance increased by 23% within three months.
Celebration of Sustain Milestones
Organizations should celebrate sustain achievements with equal enthusiasm as initial improvements. Recognizing teams that maintain improvements for six months, one year, and beyond reinforces the value of consistency. Recognition can include public acknowledgment, small rewards, or featuring successful teams in company communications.
Feedback Loop Integration
Creating mechanisms for employees to suggest modifications to sustained practices acknowledges that improvements may require refinement over time. This approach reduces resistance by demonstrating that sustained practices can evolve based on frontline insights rather than remaining rigidly fixed.
Measuring Sustain Phase Success
Quantifying sustain-phase performance requires tracking both outcome metrics and process adherence indicators. A comprehensive measurement approach includes:
- Primary performance metrics showing whether improvements maintain their impact
- Compliance rates measuring adherence to new standards
- Leading indicators identifying early warning signs of regression
- Employee engagement scores related to improvement initiatives
- Cost-benefit analyses demonstrating ongoing value
For example, a logistics company tracked the following metrics for their warehouse organization improvement: order picking accuracy maintained at 99.2% (versus 94.3% baseline), picking time sustained at 3.2 minutes per order (versus 4.7 minutes baseline), and 5S audit scores remaining above 92% for 18 consecutive months.
Overcoming Specific Resistance Scenarios
Different resistance scenarios require tailored responses. When resistance stems from genuine procedural difficulties, collaborative problem-solving sessions can identify practical solutions. When resistance reflects skepticism about value, data presentations demonstrating sustained benefits can rebuild commitment. When resistance indicates fatigue, temporary support resources or workload adjustments may prove necessary.
The key lies in diagnosing resistance accurately rather than applying generic solutions to all resistance forms.
Conclusion
Handling resistance during the Sustain phase represents perhaps the most critical skill in process improvement. While initial implementation captures attention and generates excitement, the quiet, persistent work of sustaining improvements determines whether organizations truly transform or simply experience temporary fluctuations. By understanding resistance patterns, implementing robust support structures, creating accountability systems, and building sustain-focused cultures, organizations can overcome the natural tendency toward regression and achieve lasting improvement.
Success in the Sustain phase requires dedication, strategic thinking, and comprehensive knowledge of change management principles. The strategies outlined above provide a foundation, but deep expertise comes through structured learning and practical application.
