In the journey of process improvement, achieving results is only half the battle. The true measure of success lies in sustaining those improvements over time. The Control Phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology represents the critical final step where organizations transition from project mode to operational excellence. At the heart of this transition lies an often underestimated element: a robust communication plan for ongoing performance.
Understanding the Critical Role of Communication in the Control Phase
The Control Phase ensures that the gains achieved during process improvement initiatives become embedded in the organizational fabric. Without effective communication, even the most successful improvements can deteriorate, returning processes to their previous inefficient states. A well-structured communication plan serves as the backbone of sustainable performance, ensuring that all stakeholders remain informed, engaged, and accountable for maintaining the new standards.

Communication in the Control Phase goes beyond simple status updates. It encompasses the systematic sharing of performance metrics, deviation alerts, corrective action plans, and success stories that reinforce the value of the improvements. This ongoing dialogue creates a culture of continuous monitoring and collective ownership of process excellence.

Components of an Effective Communication Plan
Stakeholder Identification and Segmentation
The foundation of any successful communication plan begins with identifying who needs to receive information and why. Stakeholders in the Control Phase typically fall into several categories: executive leadership, process owners, frontline employees, customers, and support functions. Each group requires different types of information at varying frequencies and levels of detail.
For example, executive leadership might need monthly dashboard reviews highlighting key performance indicators (KPIs), while process operators require daily visual management boards showing real-time performance against targets. A manufacturing facility that recently improved its defect rate from 4.2% to 1.8% through a Six Sigma project would communicate these different aspects to different audiences based on their decision-making needs.
Key Performance Indicators and Metrics Selection
Selecting the right metrics to communicate is crucial for maintaining focus on what truly matters. The communication plan should identify primary and secondary metrics that directly reflect the process improvements achieved. These metrics must be measurable, relevant, and easily understood by the intended audience.
Consider a customer service center that implemented improvements to reduce average call handling time. The communication plan might track and share the following metrics:
- Average call handling time: reduced from 8.3 minutes to 5.7 minutes
- First call resolution rate: improved from 67% to 84%
- Customer satisfaction score: increased from 3.2 to 4.5 out of 5
- Employee satisfaction with new procedures: 78% positive feedback
- Cost per call: decreased from $12.40 to $8.90
These metrics tell a comprehensive story of improvement and provide tangible evidence of success that can be communicated across various channels.
Communication Channels and Frequency
The effectiveness of a communication plan depends significantly on selecting appropriate channels and establishing optimal communication frequencies. Different situations call for different approaches. Daily huddles might work well for operational teams, while monthly reports suit senior management review processes.
A comprehensive communication plan might include:
- Daily shift briefings for frontline staff (5-10 minutes)
- Weekly performance reviews with team leaders (30 minutes)
- Monthly management reports with trend analysis
- Quarterly business reviews with executive sponsors
- Real-time digital dashboards accessible to all relevant parties
- Exception-based alerts when performance deviates from control limits
Building the Communication Plan: A Practical Framework
Establishing Communication Objectives
Every communication within the Control Phase should serve specific objectives. These might include maintaining awareness of current performance levels, triggering corrective actions when needed, recognizing achievements, reinforcing behavioral changes, or gathering feedback for further refinement. Clear objectives prevent communication from becoming routine noise that stakeholders begin to ignore.
Developing Standard Reporting Templates
Consistency in communication format helps stakeholders quickly understand and act on information. Standard templates should include current performance data, comparison to target values, trend indicators, and any required actions. Visual elements such as control charts, run charts, and traffic light indicators make information more accessible and actionable.
For instance, a hospital that improved patient discharge processes might use a standard weekly report template showing:
- Current week discharge time: 2.3 hours average
- Target discharge time: 2.5 hours maximum
- Previous four weeks trend: 2.8, 2.6, 2.4, 2.3 hours (positive trend)
- Number of discharges exceeding 4 hours: 3 (down from baseline of 23)
- Patient satisfaction with discharge process: 89% (up from 64%)
Creating Escalation Protocols
Not all information requires the same urgency of communication. The communication plan must define clear escalation protocols that specify when and how to communicate performance deviations. These protocols should outline the thresholds that trigger escalations, who needs to be notified, expected response timeframes, and documentation requirements.
When a process exceeds its control limits, immediate communication becomes essential. A manufacturing process with an upper control limit of 2% defect rate should have predetermined escalation steps if the rate reaches 2.5%, including immediate notification to the production supervisor, quality manager, and process owner, followed by a rapid response team meeting within two hours.
Implementing Visual Management Systems
Visual management represents one of the most powerful communication tools in the Control Phase. These systems translate complex data into easily digestible visual formats that enable quick understanding and decision-making. Visual boards placed in work areas create constant awareness and facilitate real-time communication about performance.
A logistics company that improved its delivery accuracy from 91% to 98.5% might implement visual management boards at distribution centers showing daily performance against target, a monthly trend chart, recognition of best-performing teams, and a section highlighting any special challenges or upcoming changes. This visual presence keeps improvement top of mind and creates peer accountability for maintaining standards.
Sustaining Engagement Through Strategic Communication
The most technically perfect communication plan will fail if stakeholders become disengaged. Sustaining interest requires variety in communication approaches, celebration of successes, transparency about challenges, and opportunities for two-way dialogue. Regular communication should include success stories that highlight how the improvements have made work easier, improved customer outcomes, or contributed to organizational goals.
Recognition programs integrated into the communication plan can significantly boost engagement. When a team maintains performance within control limits for three consecutive months, this achievement should be communicated and celebrated. Such recognition reinforces desired behaviors and motivates continued adherence to improved processes.
Measuring Communication Effectiveness
Like any other process, communication plans require measurement and continuous improvement. Effectiveness can be assessed through metrics such as stakeholder awareness levels, response times to performance alerts, attendance at review meetings, and feedback surveys. If communication is effective, stakeholders should demonstrate clear understanding of current performance, know their role in maintaining improvements, and take appropriate actions when required.
Periodic audits of the communication plan help identify gaps or redundancies. Questions to consider include: Are people receiving information they need when they need it? Is any communication being ignored? Are there stakeholder groups not receiving adequate information? Are response times to performance issues acceptable?
Common Pitfalls to Avoid
Several common mistakes can undermine communication plans in the Control Phase. Over-communication with too much data can overwhelm stakeholders and lead to disengagement. Conversely, under-communication leaves people uninformed and unable to maintain improvements. Inconsistent communication creates confusion about priorities and expectations. One-way communication that does not allow for feedback misses valuable insights from those closest to the process.
Another critical mistake is failing to adapt the communication plan as circumstances change. As processes stabilize and mature, communication needs evolve. What required daily attention initially might transition to weekly monitoring. The communication plan must remain a living document that adapts to the changing needs of the organization.
Conclusion
Creating and maintaining effective communication plans for ongoing performance represents a critical success factor in the Control Phase of process improvement initiatives. These plans transform temporary project gains into permanent organizational capabilities by keeping stakeholders informed, engaged, and accountable. Through careful stakeholder analysis, appropriate metric selection, strategic channel utilization, and consistent execution, organizations can ensure that their hard-won improvements endure.
