Process improvement initiatives often fall short not because of poor analysis or inadequate solutions, but due to the absence of robust standardisation plans. In the Improve phase of Lean Six Sigma methodology, creating comprehensive process standardisation plans becomes the bridge between theoretical improvements and sustainable operational excellence. This critical step ensures that the gains achieved through rigorous analysis and testing become embedded in daily operations, preventing the all-too-common scenario of reverting to old habits.
Understanding Process Standardisation in the Improve Phase
Process standardisation represents the systematic documentation and implementation of the best-known method for completing a task or series of tasks. Within the Improve phase of DMAIC (Define, Measure, Analyse, Improve, Control), standardisation transforms validated improvements into repeatable, consistent practices that every team member can follow. This transformation is essential for organisations seeking to maintain competitive advantages and deliver consistent quality to their customers.

The foundation of effective standardisation rests on three pillars: clarity, accessibility, and adaptability. Standards must be clearly articulated so that anyone performing the process understands exactly what is expected. They must be accessible to all stakeholders who need them, and they must be adaptable enough to accommodate necessary changes without compromising the core improvements achieved.

The Business Case for Process Standardisation
Consider a manufacturing company that reduced defect rates from 8.5% to 2.1% through process improvements. Without proper standardisation, these gains eroded within six months, with defect rates climbing back to 7.2%. This example illustrates the critical importance of standardisation in protecting improvement investments.
Standardisation delivers measurable benefits across multiple dimensions. Quality consistency improves as variation decreases between different operators, shifts, or locations. Training time for new employees decreases significantly when clear, standardised procedures exist. Problem-solving becomes more efficient because deviations from the standard are immediately apparent. Perhaps most importantly, standardisation creates a baseline for future improvement efforts.
Key Components of a Process Standardisation Plan
Standard Operating Procedures (SOPs)
Standard Operating Procedures form the cornerstone of any standardisation plan. Effective SOPs go beyond simple checklists to provide comprehensive guidance on process execution. They should include the purpose of the procedure, scope of application, required materials and equipment, detailed step-by-step instructions, quality checkpoints, and troubleshooting guidance.
For example, a customer service centre implementing improved call handling procedures might document the following: greeting script with specific phraseology, information gathering sequence with mandatory fields, problem categorisation system with decision trees, resolution steps for the top 20 issue types, escalation criteria and procedures, and call closing protocols including follow-up commitments.
Visual Management Tools
Visual management tools translate written standards into easily digestible visual formats that facilitate quick understanding and compliance. These tools include process flowcharts showing the sequence of activities, visual work instructions using photographs or illustrations, control charts displaying normal variation ranges, and status boards tracking real-time performance against standards.
A practical example comes from a hospital emergency department that reduced patient waiting times by 35%. They created visual standards including colour-coded patient priority systems, wall-mounted flowcharts for triage procedures, digital dashboards showing current wait times by category, and photographic guides for examination room setup. These visual tools enabled staff to maintain improved processes even during high-stress situations.
Training and Competency Verification
Documentation alone does not create standardisation. People must understand and be capable of following the standards. A comprehensive training programme should include initial training for all affected personnel, hands-on practice sessions with feedback, competency assessments before independent operation, refresher training at regular intervals, and training updates when standards change.
Consider this sample training verification matrix for a quality inspection process:
Operator Name: Sarah Johnson
Process: Final Product Inspection
Training Date: March 15, 2024
Trainer: Michael Chen
- Visual inspection criteria: Demonstrated competency on 25 consecutive units with 100% accuracy
- Measurement tool usage: Passed written test (95%) and practical assessment
- Defect categorisation: Correctly classified 48 out of 50 sample defects
- Documentation procedures: Completed 20 inspection reports with zero errors
- Escalation protocols: Demonstrated understanding through scenario-based assessment
Certification Status: Approved for independent operation
Recertification Due: September 15, 2024
Developing Your Standardisation Plan: A Step-by-Step Approach
Step 1: Document Current Best Practice
Begin by thoroughly documenting the improved process that pilot testing has validated. Involve the people who will actually perform the process in this documentation effort. Their insights ensure that standards reflect practical reality rather than theoretical ideals. Capture not only what should be done but why it matters, helping operators understand the rationale behind each step.
Step 2: Identify Critical Control Points
Not all process steps carry equal importance. Identify critical control points where variation has the greatest impact on outcomes. These points require more detailed standards, tighter monitoring, and potentially additional safeguards. For instance, in a loan approval process, credit score verification and income documentation validation might be critical control points requiring enhanced standardisation.
Step 3: Create Layered Documentation
Develop documentation at multiple levels to serve different needs. High-level process maps provide overview understanding. Detailed work instructions guide daily execution. Quick reference guides support on-the-job performance. Technical specifications define equipment settings and tolerances. This layered approach ensures that everyone can access the right level of detail for their needs.
Step 4: Design Feedback Mechanisms
Standards should not be static documents gathering dust on shelves. Build in feedback mechanisms that capture insights from daily use. This might include regular review meetings, suggestion systems for standard improvements, periodic audits comparing actual practice to documented standards, and performance data analysis revealing where standards may need adjustment.
Step 5: Plan the Rollout Strategy
Successful standardisation requires careful rollout planning. Consider whether a phased implementation by department, shift, or location makes sense, or if simultaneous deployment is preferable. Identify change champions who will support adoption. Plan communication campaigns that explain the benefits of standardisation. Ensure adequate support resources during the transition period.
Overcoming Common Standardisation Challenges
Resistance to standardisation often stems from concerns about lost autonomy or one-size-fits-all thinking. Address these concerns by emphasising that good standards capture best practices while allowing appropriate flexibility. Involve frontline workers in standard development to build ownership. Demonstrate through data how standardisation enables rather than constrains good performance.
Another common challenge involves maintaining standards over time. Combat standard erosion through regular audits, visible leadership commitment, and incorporating standard adherence into performance management systems. Celebrate successes where following standards led to excellent outcomes. Make standard review and improvement a regular part of team meetings.
Measuring Standardisation Effectiveness
Effective standardisation plans include metrics for tracking both implementation and impact. Implementation metrics might include percentage of personnel trained and certified, audit scores for standard compliance, and frequency of standard deviations. Impact metrics connect standardisation to business results such as defect rates, cycle times, customer satisfaction scores, and cost per unit.
For example, a logistics company implementing standardised loading procedures might track: training completion rate (target: 100% within 30 days), loading procedure compliance rate (target: greater than 95% on random audits), loading time variation (target: standard deviation less than 5 minutes), and damage incidents per 1,000 shipments (target: less than 2).
The Path Forward: From Standardisation to Continuous Improvement
Process standardisation is not the end of improvement but rather the foundation for continuous advancement. Once standards establish a stable baseline, teams can more effectively identify opportunities for further improvement. Standardisation creates the discipline and structure necessary for sustaining gains while building capability for future innovation.
Organisations that excel at standardisation develop distinctive capabilities that competitors find difficult to replicate. They build cultures where following standards is seen not as rigid compliance but as professional excellence. They create systems where improvement and standardisation work in virtuous cycles, each reinforcing the other.
