Consider this scenario: A multinational hospitality group with a strong presence in North America is facing significant challenges in maintaining operational excellence.

Despite being a market leader, the company has observed a decline in customer satisfaction scores and an increase in service delivery times. The group's leadership is concerned that these issues are symptomatic of deeper operational inefficiencies that could impact the organization's long-term profitability and market position. The hospitality group is looking to adopt Six Sigma methodologies to improve process efficiency, enhance customer experience, and maintain a competitive edge.



In reviewing the operational challenges of the hospitality group, two hypotheses emerge as likely contributors to the decline in performance: First, that there may be variability and defects in service processes that are leading to customer dissatisfaction, and second, that inefficient resource allocation is causing increased service delivery times.

Strategic Analysis and Execution Methodology

The proven methodology for addressing such operational challenges involves a structured 5-phase Six Sigma project approach that will not only identify the root causes of inefficiency but also provide a clear path to sustainable improvement. This approach, which is akin to the DMAIC (Define, Measure, Analyze, Improve, Control) model used by top consulting firms, offers a systematic framework for problem-solving and process enhancement.

  1. Define Phase: Identify critical service delivery processes and define the project scope. Key questions include: What are the customer pain points? What processes impact customer satisfaction the most? Activities include stakeholder interviews and setting project objectives. Insights into the most impactful service areas are expected, with common challenges around scope creep.
  2. Measure Phase: Collect data on current process performance. Key activities involve process mapping and data collection. Analyses focus on identifying process variation and capability. Insights into the true performance metrics will be gained, with challenges often arising from data integrity issues.
  3. Analyze Phase: Analyze the data to identify root causes of inefficiencies. Key questions include: Why are these defects occurring? Where are the bottlenecks in the process? Activities include root cause analysis and data analysis techniques. Potential insights into specific process failures will be developed, with challenges related to isolating variables.
  4. Improve Phase: Develop and implement solutions to eliminate the root causes. Key activities include solution ideation, piloting changes, and process redesign. Insights into the most effective improvements will be made, with challenges often encountered in change management and staff resistance.
  5. Control Phase: Implement controls to sustain the improvements. Key activities include developing control plans, training, and monitoring. Insights into long-term sustainability of process changes will be critical, with common challenges in maintaining discipline and adherence to new processes.

Six Sigma Project Implementation Challenges & Considerations

One consideration for executives is the scalability of solutions across the organization. The methodology must be adaptable to different service areas while maintaining consistency in results. Secondly, the financial investment in Six Sigma projects is significant; however, the return on investment can be justified by the long-term cost savings and improved customer loyalty. Lastly, the integration of new technologies and systems to support Six Sigma initiatives may be necessary, which requires careful planning and execution.

Upon full implementation of the Six Sigma project, the hospitality group can expect reduced process variation, improved service delivery times, and enhanced customer satisfaction. These outcomes should lead to increased market share and profitability. Quantifiable improvements, such as a reduction in customer complaints by 30% within the first year, are anticipated.

Implementation challenges may include resistance to change from staff accustomed to existing procedures, difficulties in maintaining discipline in following new processes, and the need for ongoing training and development to ensure the improvements are sustained over time.

Six Sigma Project KPIs

KPIS are crucial throughout the implementation process. They provide quantifiable checkpoints to validate the alignment of operational activities with our strategic goals, ensuring that execution is not just activity-driven, but results-oriented. Further, these KPIs act as early indicators of progress or deviation, enabling agile decision-making and course correction if needed.


What gets measured gets done, what gets measured and fed back gets done well, what gets rewarded gets repeated.
     – John E. Jones

  • Customer Satisfaction Scores: Indicates the level of customer happiness and is a direct reflection of service quality.
  • Process Cycle Time: Measures the efficiency of the service delivery process.
  • Defect Rate: Tracks the frequency of errors in the service process, aiming for reduction.
  • Cost of Poor Quality: Quantifies the financial impact of defects and inefficiencies.

Implementation Insights

During the implementation of the Six Sigma project, it became evident that leadership commitment is paramount. A study by McKinsey showed that 70% of complex, large-scale change programs don't reach their stated goals, largely due to employee resistance and lack of management support. Executives must not only endorse the project but also actively participate in creating a culture of continuous improvement.

Another insight is the value of cross-functional teams. Diverse perspectives lead to more innovative solutions and increased buy-in across the organization. Furthermore, involving front-line employees who are intimately familiar with the day-to-day operations can unearth practical insights that might be overlooked by management.

Customizing Six Sigma for Service Industries

While Six Sigma originated in manufacturing, its principles are equally applicable to service industries, albeit with necessary customizations. In the hospitality industry, for instance, variability in customer expectations and the intangible nature of service delivery necessitate a modified approach to the traditional Six Sigma toolset.

Accenture reports that successful application of Six Sigma in services involves a greater focus on the customer experience and less on the statistical tools that are often emphasized in manufacturing. This adaptation ensures that improvements are meaningful to customers and directly contribute to increased satisfaction and loyalty.

Measuring the Return on Investment

Measuring the return on investment (ROI) for Six Sigma projects is a complex but vital aspect of justifying the methodology's adoption. Executives often look for quantifiable metrics that can demonstrate the financial benefits of process improvements. The ROI can be calculated by assessing the cost reductions and efficiency gains against the investment made in training, resources, and time.

As per PwC, organizations that implement Six Sigma can expect an average return of about $2 for every $1 invested in the first year of implementation. However, this figure can vary widely depending on the scope and effectiveness of the projects. It's crucial to have a robust measurement system in place to track these financial outcomes accurately.

Scaling Six Sigma across Multiple Locations

Scaling Six Sigma across multiple locations presents a unique set of challenges, particularly in ensuring consistency and maintaining quality standards. A standardized approach to training and certification can help in achieving uniformity in methodology application. Moreover, leveraging technology to share best practices and collaborate on projects can bridge the gaps between geographically dispersed teams.

Deloitte's insights indicate that organizations with a centralized repository for Six Sigma resources and a dedicated support infrastructure are better equipped to scale their initiatives across various locations. This centralization fosters a culture of continuous improvement and allows for more efficient knowledge transfer and resource allocation.

Addressing Change Management and Cultural Resistance

Change management is a critical component of implementing Six Sigma projects. Resistance to change is a natural human tendency, and in the context of process improvement initiatives, it can manifest as skepticism or reluctance to adopt new methodologies. To counter this, it is imperative to involve all levels of the organization in the change process, from executives to frontline employees.

According to McKinsey, successful change programs often include comprehensive communication strategies, training programs tailored to different employee roles, and visible support from leadership. By cultivating a culture that values data-driven decision-making and continuous improvement, organizations can overcome resistance and embed Six Sigma principles into their operational DNA.
