Enhanced Process Capability Reporting using a Free App

In today’s competitive business environment, mastering the art of process capability reporting is essential. This blog delves into the innovative approach of 30,000-foot-level predictive performance reporting within the Integrated Enterprise Excellence (IEE) business management system, offering a novel and powerful perspective on process capability analysis.

 

Revolutionizing Process Capability Reporting: Traditional process capability indices like Cp, Cpk, Pp, and Ppk, though useful, often fall short of offering a clear understanding of a process’s capabilities. The 30,000-foot-level reporting methodology, a core element of the IEE system, transcends these limitations by providing a more comprehensive view of process performance.

 

Understanding 30,000-Foot-Level Reporting: The reporting method is akin to viewing process performance from a high altitude, offering a broader and more strategic perspective. It emphasizes the stability and predictability of processes, providing predictive performance statements that are easy to understand and actionable.

 

Enhanced Process Capability Reporting

Critical Benefits of Enhanced Process Capability Reporting are:

  • Additional Visibility: This method offers a clear, high-level view of process output over time, integrating process variability into the reporting structure.
  • Predictive Analysis: It focuses on creating predictive statements about processes, aiding in proactive decision-making.
  • Process Improvement Focus: When a process futuristic projected response underperforms, the method directs attention towards improvement using methodologies like Lean Six Sigma DMAIC.
  • Applications Across Diverse Metrics: The versatility of this reporting method is evident in its applicability to a wide array of process performance and Key Performance Indicator (KPI) metrics, from customer satisfaction to production yields.

Continuous Improvement and Operational Excellence: By adopting this enhanced approach to process capability reporting, organizations can foster a culture of continuous improvement, aligning process performance more closely with strategic objectives.

 

By integrating the enhanced concepts of 30,000-foot-level reporting in process capability analysis, businesses can gain a more accurate and actionable understanding of their processes. This improved process capability reporting approach identifies areas for improvement and tracks the long-term impact of these enhancements, driving toward operational excellence.

 

Example: Enhanced Process Capability Reporting

A product specification is 72-78. Twenty time-sequenced product measurements were:

 

A Minitab process capability report for this data is:

traditional process capability reporting

 

Assessment of this commonplace process capability indices reporting format:

  • From this report, one does not know whether the data originates from a stable process (for the process capability report to be valid, data needs to be from a stable process).
  • Cp, Cpk, Pp, and Ppk values are difficult to understand and explain to others.
  • The report is not helpful to determine if a process response improved or degraded over time.

 

A 30,000-foot-level report for this data using a free app is:

Assessment of this process capability indices report:

  • The individuals chart on the left side of the report indicates the process is stable.
  • The probability plot on the right in this figure may initially look intimidating. However, after overcoming any initial intimidation, one will find that this probability plot is easy to use and can provide much insight into the process relative to data normality, bi-modality, how a process is performing, etc.
  • The probability plot provides an easy-to-understand methodology for determining a process’s capability when a specification exists or when there is no specification.
  • The statement at the bottom of the report describes the process’s capability (from the probability plot) in words that are easier to understand than Cp, Cpk, Pp, and Ppk units.
  • One report-out provides a process stability assessment and capability statement if the process is stable.

 

30,000-foot-level Free App for Process Capability Reporting

  • A 30,000-foot-level Free App is available (with video instructions on how to use it) through the link “Free Business Process Management Software
  • Applications of the app include variable data (subgrouped and not subgrouped), attribute data, and identification of when a process changes with a new process capability statement.
  • No specification is needed to make a process capability statement. When a response does not have a specification (e.g., WIP – work in progress), the statement at the bottom of the report can provide an estimated mean or median process-output response with an 80% frequency of occurrence (e.g., mean monthly WIP cost of $100,000 with 80% of the months between $92,000 and $108,000).
  • If a futuristic projection of a process-output response is undesirable, there is a need for process improvement. Demonstration of the improvement of a process is the staging of the 30,000-foot-level individuals chart to an enhanced level of performance. The statement at the bottom of the 30,000-foot-level report would reflect the new process capability.
  • Can provide process capability statements for log-normal and data that need a transformation for correct analyses.
