In the journey of Lean Six Sigma implementation, the Control Phase stands as the critical final stage where organizations ensure that improvements are sustained over time. Among the essential tools for maintaining process excellence, the skill matrix and comprehensive training plans emerge as foundational elements that determine long-term success. This article explores how organizations can develop robust skill matrices and training plans that guarantee consistent performance and continuous improvement.
Understanding the Control Phase in Lean Six Sigma
The Control Phase represents the culmination of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology. After investing significant resources in identifying problems, analyzing root causes, and implementing improvements, organizations must establish mechanisms to prevent regression to previous performance levels. The skill matrix and training plans serve as vital instruments in this sustainability effort, ensuring that team members possess the necessary competencies to maintain improved processes.

Without proper documentation of required skills and structured training initiatives, even the most successful improvement projects can deteriorate. Organizations risk losing gains achieved through previous phases when personnel changes occur or when institutional knowledge remains undocumented. The skill matrix addresses this vulnerability by creating a visual representation of competencies across the team, while training plans provide the roadmap for developing and maintaining these capabilities.

What is a Skill Matrix?
A skill matrix, sometimes referred to as a competency matrix, is a structured framework that maps the skills and competencies of team members against the requirements of specific processes or tasks. This tool provides immediate visibility into capability gaps, succession planning needs, and training priorities. The matrix typically displays individual team members along one axis and required skills or competencies along the other, with proficiency levels indicated at intersections.
The skill matrix serves multiple strategic purposes within an organization. It identifies critical skills gaps that could jeopardize process performance, supports workforce planning by highlighting dependencies on specific individuals, facilitates cross-training initiatives to build organizational resilience, and provides objective data for performance evaluations and career development discussions.
Components of an Effective Skill Matrix
Skill Categories and Levels
An effective skill matrix begins with clearly defined skill categories relevant to the process under control. These categories should be specific, measurable, and directly linked to process performance. For manufacturing environments, skills might include machine operation, quality inspection, preventive maintenance, and problem-solving methodologies. For service environments, categories could encompass customer interaction protocols, software proficiency, data analysis capabilities, and compliance requirements.
Proficiency levels must be standardized across the organization. A common framework includes four levels: Level 0 representing no knowledge or capability, Level 1 indicating basic awareness with supervision required, Level 2 demonstrating independent competence with occasional guidance needed, and Level 3 signifying expert status with the ability to train others. Some organizations add a Level 4 for those who develop new methods or innovate within the skill area.
Sample Skill Matrix Structure
Consider a pharmaceutical packaging department that recently completed improvement projects reducing defect rates. Their skill matrix might include the following structure:
Process Skills Required:
- Blister packaging machine operation
- Quality control inspection procedures
- Statistical process control charting
- Root cause analysis techniques
- Standard operating procedure adherence
- Equipment changeover procedures
- Clean room protocols
- Documentation and record keeping
For a team of eight operators, the matrix would display each person’s proficiency level for every skill. Analysis might reveal that only two team members possess Level 3 proficiency in statistical process control, creating a vulnerability if these individuals are unavailable. Similarly, if only one person holds expertise in equipment changeover procedures, production flexibility becomes compromised.
Developing Comprehensive Training Plans
Once the skill matrix identifies capability gaps, organizations must create structured training plans to address deficiencies and maintain competencies. Effective training plans extend beyond simple scheduling of courses; they encompass learning objectives, delivery methods, assessment criteria, and continuous improvement mechanisms.
Training Needs Assessment
The skill matrix provides quantitative data for prioritizing training needs. Organizations should consider several factors when determining training priorities. Critical skills that directly impact customer satisfaction or regulatory compliance demand immediate attention. High-risk areas where only one or two individuals possess necessary expertise require urgent cross-training initiatives. Frequently performed tasks with multiple skill gaps should be addressed to improve overall team capability. Emerging technologies or process changes necessitate proactive training before implementation.
Training Plan Components
A comprehensive training plan includes specific elements that transform skill gaps into development opportunities. Learning objectives must be clearly articulated using measurable terms. Rather than stating “understand quality procedures,” effective objectives specify “demonstrate ability to identify five common defect types and execute appropriate corrective actions within standard time parameters.”
Training methods should align with learning objectives and organizational resources. Options include on-the-job training with experienced mentors, formal classroom instruction for theoretical knowledge, simulation-based learning for high-risk procedures, e-learning modules for flexible self-paced development, job rotation programs for cross-functional exposure, and certification programs for specialized competencies.
Assessment criteria establish clear standards for determining competency achievement. These might include written examinations for knowledge verification, practical demonstrations observed by qualified assessors, time-based performance metrics for efficiency requirements, and quality metrics measuring accuracy and consistency.
Practical Implementation Example
Consider a financial services call center that implemented process improvements reducing average call handling time while maintaining customer satisfaction scores. Their Control Phase implementation included the following approach:
The team identified twelve critical skills including product knowledge across four service categories, CRM system navigation, complaint resolution protocols, compliance requirements, active listening techniques, de-escalation strategies, cross-selling approaches, and data entry accuracy standards.
Their initial skill matrix assessment of twenty-five team members revealed significant gaps. Only eight members demonstrated Level 2 or higher proficiency in de-escalation strategies. Fifteen members required training in updated compliance requirements. Three senior members possessed Level 3 expertise across most categories but were approaching retirement age.
The resulting training plan established priorities addressing compliance training for all staff within thirty days through mandatory e-learning modules with assessment. De-escalation skills development occurred through monthly workshops with role-playing exercises over six months. Knowledge transfer initiatives paired senior experts with junior staff for structured mentoring relationships over twelve months. Cross-training rotations enabled all team members to achieve Level 2 proficiency in at least three of four product categories within eighteen months.
Quarterly skill matrix updates tracked progress and identified emerging gaps. After twelve months, the center demonstrated improved resilience with average skill levels increasing across all categories. The percentage of team members at Level 0 for any critical skill decreased from thirty-two percent to eight percent. Customer satisfaction scores remained stable despite the retirement of two senior team members, validating the knowledge transfer success.
Maintaining and Updating the System
Skill matrices and training plans require regular maintenance to remain effective. Organizations should establish review cycles aligned with performance evaluation periods, typically quarterly or semi-annually. These reviews should assess skill level changes as individuals complete training, identify new skill requirements as processes evolve, update proficiency standards based on performance data, and recognize skill degradation when individuals move to different roles or skills remain unused for extended periods.
Technology solutions can streamline skill matrix management through automated tracking systems, integration with learning management platforms, visual dashboards highlighting gaps and trends, and automated alerts when critical skills fall below threshold levels. However, even simple spreadsheet-based matrices provide substantial value when consistently maintained.
Benefits Beyond Process Control
While skill matrices and training plans directly support Control Phase objectives, their benefits extend throughout the organization. These tools enhance employee engagement by demonstrating organizational investment in development and providing clear career progression pathways. They improve operational resilience by reducing dependency on individual knowledge holders and enabling flexible workforce deployment. Organizations gain stronger succession planning capabilities by identifying future leaders and preparing them systematically. Budget allocation becomes more strategic when training investments align with documented skill gaps rather than reactive requests.
Common Implementation Challenges
Organizations frequently encounter obstacles when developing these systems. Resistance may emerge from team members who perceive assessment as threatening or from managers who view documentation as administrative burden. Addressing these concerns requires clear communication about developmental rather than punitive purposes and demonstrating time savings through reduced crisis management when skills are properly maintained.
Maintaining current information presents ongoing challenges, particularly in larger organizations. Assigning clear ownership for matrix updates and integrating reviews into existing management routines helps ensure sustainability. Starting with pilot implementations in critical areas allows organizations to refine approaches before enterprise-wide deployment.
Conclusion
The Control Phase determines whether process improvements become permanent fixtures or temporary fluctuations. Skill matrices and training plans provide the foundation for sustainable excellence by ensuring organizational capability matches process requirements. These tools transform tacit knowledge into documented competencies, individual expertise into team capabilities, and reactive training into strategic development.
Organizations that invest in comprehensive skill assessment and structured training planning position themselves for enduring competitive advantage. The initial effort required to develop these systems yields returns through improved process stability, enhanced workforce flexibility, and reduced vulnerability to personnel changes. As processes evolve and improve, the skill matrix and training plan evolve accordingly, creating a virtuous cycle of capability development and performance enhancement.
