Healthcare organizations invest significant resources in improving clinical processes, yet many initiatives fail to deliver lasting results. The control phase, a critical component of Lean Six Sigma methodology, provides the framework needed to sustain improvements and ensure patient safety remains paramount. Understanding how to effectively implement control mechanisms in healthcare settings can mean the difference between temporary gains and transformational change.
Understanding the Control Phase in Healthcare Context
The control phase represents the final stage of the DMAIC (Define, Measure, Analyze, Improve, Control) cycle in Lean Six Sigma projects. While many healthcare professionals recognize phase improvements when they see initial positive outcomes, maintaining these gains requires systematic planning and ongoing vigilance. This phase ensures that hard-won improvements become embedded in daily clinical practice rather than fading away once project teams disband or attention shifts to new priorities.

In healthcare environments, the stakes are particularly high. Unlike manufacturing or service industries where process failures might result in financial losses or customer dissatisfaction, healthcare process breakdowns can directly impact patient safety and clinical outcomes. This reality makes the control phase not just important but essential for maintaining quality care standards.

Key Components of an Effective Control Strategy
Documentation and Standardization
The foundation of any successful control phase begins with thorough documentation of improved processes. Healthcare teams must create clear, accessible standard operating procedures that reflect the new workflows. These documents should include: You might also enjoy reading about Lessons Learned Documentation: Capturing Knowledge for Future Projects.
- Step-by-step process descriptions with visual aids
- Decision trees for handling variations or exceptions
- Quality checkpoints and verification methods
- Roles and responsibilities for each process step
- Evidence-based rationale for key process elements
Documentation alone, however, proves insufficient. Healthcare organizations must ensure these materials remain living documents, regularly reviewed and updated based on practical experience and emerging evidence. Standard work should be readily available at point of care, whether through laminated cards, electronic health record integration, or departmental quick-reference guides.
Monitoring Systems and Metrics
Effective control requires continuous monitoring through carefully selected metrics. Healthcare teams implementing lean six sigma principles must identify key performance indicators that accurately reflect process health without creating excessive measurement burden. These metrics should balance outcome measures (patient results), process measures (adherence to protocols), and balancing measures (unintended consequences).
Control charts, run charts, and dashboards provide visual representation of process performance over time. These tools help teams quickly recognize phase shifts, trends, or special cause variation that might indicate process deterioration. Regular metric review, typically monthly or quarterly depending on process volume, allows for timely intervention before small deviations become significant problems.
Response Plans and Escalation Procedures
Every control plan must include clear procedures for responding when metrics indicate process deviation. Healthcare teams should establish thresholds that trigger investigation and define who takes responsibility for various types of issues. This proactive approach prevents the gradual erosion of improvements through benign neglect or competing priorities.
Response plans should specify investigation methods, documentation requirements, and decision authority for process adjustments. In clinical settings, these plans must also address patient safety implications and integrate with existing risk management structures.
Training and Competency Verification
Sustained improvement depends heavily on staff competency and engagement. Initial training during the improve phase must be reinforced through ongoing education, especially as staff turnover occurs. Healthcare organizations should develop competency verification methods appropriate to the process complexity and risk level.
Effective training strategies include:
- Structured onboarding programs for new staff members
- Regular refresher training for existing team members
- Just-in-time learning resources for infrequent procedures
- Simulation or skills lab practice for high-risk processes
- Peer coaching and mentorship programs
Organizations applying lean six sigma principles recognize phase training not as a one-time event but as an ongoing organizational commitment. Building training into regular staff development schedules helps normalize continuous improvement culture.
Creating Accountability Structures
Clear ownership ensures someone remains responsible for process health long after project completion. Healthcare organizations should designate process owners with explicit accountability for monitoring, responding to deviations, and facilitating continuous refinement. These individuals need appropriate authority, resources, and organizational support to fulfill their responsibilities effectively.
Regular process audits complement ongoing monitoring by providing independent verification of adherence to standard work. These audits should be constructive rather than punitive, focusing on system issues rather than individual blame. Audit findings should feed directly into process improvement cycles, creating a feedback loop that drives continued enhancement.
Sustaining Cultural Change
Technical control mechanisms prove insufficient without supportive organizational culture. Healthcare leaders must actively champion improved processes, celebrating successes and addressing barriers that impede adherence. This requires visibility, with senior leaders regularly reviewing process performance and participating in problem-solving when issues arise.
Staff engagement remains crucial for long-term sustainability. Frontline clinicians and staff who participate in process design and refinement develop ownership and become improvement advocates. Organizations should create forums for staff to share concerns, suggest modifications, and recognize phase improvements that enhance both efficiency and quality.
Integration with Existing Systems
Improved processes cannot exist in isolation. Successful control phases ensure new workflows integrate seamlessly with existing clinical systems, quality programs, and regulatory requirements. This integration includes:
- Alignment with electronic health record workflows
- Connection to existing quality reporting structures
- Incorporation into accreditation and regulatory compliance programs
- Coordination with risk management and patient safety initiatives
- Links to performance improvement and peer review processes
By embedding improvements within established organizational structures, healthcare teams increase the likelihood of sustained adherence and reduce the perception of improvement initiatives as “extra work.”
Common Pitfalls and How to Avoid Them
Healthcare organizations frequently encounter predictable challenges during the control phase. Recognizing these pitfalls enables proactive mitigation strategies. Common issues include declaring victory too early, creating overly complex control systems that burden staff, failing to address competing priorities, and neglecting to refresh training as staff changes occur.
Successful organizations maintain realistic timelines, understanding that embedding new processes typically requires six to twelve months of active control phase management. They design simple, elegant monitoring systems that provide maximum insight with minimum effort. They also acknowledge that improvement work competes with numerous other priorities and secure necessary resources rather than expecting staff to simply work harder.
Measuring Control Phase Success
How do healthcare organizations know their control phase is working? Success indicators include sustained improvement in key metrics over time, high adherence rates to standardized processes, rapid identification and resolution of deviations, and staff confidence in executing new workflows. Organizations should also assess whether improvements have been successfully replicated in other units or departments, indicating true process maturity.
Long-term success requires patience and persistence. Healthcare leaders should resist the temptation to prematurely move on to the next improvement project before adequately securing current gains. The discipline of thorough control phase execution ultimately determines whether lean six sigma initiatives deliver lasting value or simply create temporary disruption.
Conclusion
The control phase represents where improvement theory meets practical sustainability in healthcare settings. While less glamorous than breakthrough moments during the analyze and improve phases, control phase activities determine whether patient care truly benefits from improvement efforts. Healthcare organizations that recognize phase control as equally important to initial improvement design position themselves for genuine, lasting transformation. By implementing robust monitoring systems, maintaining staff competency, creating clear accountability, and fostering supportive culture, healthcare teams can ensure that clinical process improvements continue delivering value long into the future.
