How do you monitor and control the variation and capability of your processes?

While defining operational processes I like to emphasize with the end user too, highlighting the importance of understanding the practical aspects of how the process is executed on the ground. Thus I find it valuable not only to break down the complexity of the process itself but also to look into it through the lenses of a person who runs the process. I am interested in understanding not only the actions he needs to take to succeed but also which tools he uses. By considering the tools and actions involved from the user's perspective, I'm likely to uncover insights into potential inefficiencies, pain points, or areas for improvement. This can inform decisions about optimization, automation, or even redesigning aspects of the process.

In my experience, to have an agile approach in defining the processes is important. One should not be afraid to reassess if needed instead of plowing ahead once the defining phase is completed.

In logistics, start by clearly defining your process, identifying inputs, outputs, and key steps. Determine customer requirements for the output, including target value, specification limits, and tolerance range. This establishes standards and criteria for assessing process performance and quality, crucial for maintaining high efficiency and customer satisfaction in logistics operations.

A coleta de dados é fundamental para o monitoramento e o controle da varia??o e da capacidade dos processos, pois permite uma análise detalhada do desempenho e das possíveis causas de varia??o. Aqui est?o algumas maneiras específicas de como isso auxilia: 1- Identifica??o de Varia??es 2- Controle Estatístico do Processo (CEP) 3- Capacidade do Processo 4- Tomada de Decis?o Baseada em Dados 5- Melhoria Contínua

Defining a process flow involves several key steps: 1. Gather your process steps. 2. Decide on the actions to be taken. 3. Set clear goals. 4. Ensure all steps are well-defined. With these elements in place, your process flow will be ready to go!

Collecting accurate data is a cornerstone of monitoring and controlling process variation and capability. In the construction industry, this means systematically recording key metrics such as material usage, labor hours, and equipment efficiency. Leveraging technology, such as IoT sensors and construction management software, can significantly enhance data accuracy and accessibility. Reliable data collection enables project managers to identify patterns, measure performance against benchmarks, and make informed decisions to improve process efficiency and reduce variability.

Collect data on process inputs and outputs using check sheets, histograms, control charts, Pareto charts, scatter diagrams, and run charts. The data type and quantity depend on your process's complexity and desired accuracy. Ensure data collection spans a time period representing your process's normal variation for a comprehensive understanding.

In my experience, one should be careful in the data collection phase to make sure there is no biases, preconceived ideas skewing data, etc. Too small or to focused data collection should also be avoided.

Picture yourself panning for data nuggets. You’re the prospector! Measure flow rates, temperatures, chemical concentrations—the whole shebang. Sensors and analyzers are your trusty pickaxes. They chip away at uncertainty. ??

Para recopilar datos de calidad, primero es crucial calcular el tama?o de la muestra adecuado, lo cual depende de la métrica a estudiar. Un nivel de confianza del 95% con un margen de error del 5% suele ser lo común, aunque puede variar según el proyecto. Una vez definido el tama?o de la muestra, elige un sistema de medición efectivo que se ajuste al plazo disponible. Posteriormente, realiza un estudio Gage R&R para validar que el sistema de medición es confiable. Solo después de este proceso, comienza a recopilar los datos, asegurándote de que sean precisos y de calidad. ??

Calculate your process variation and capability using statistical methods. Utilize measures like standard deviation, range, mean, and median to quantify output variation. Apply indices such as Cp, Cpk, Pp, and Ppk to assess how well the process meets customer specifications. These indices compare process variation to specification limits, indicating the process's centeredness and spread, providing a clear statistical view of process performance and quality.

Para calcular la variación y la capacidad de tu proceso, utiliza métricas como Cp, Cpk, Pp y Ppk. Estas te ayudarán a medir qué tan bien tu proceso cumple con las especificaciones del cliente. Por ejemplo, un Cp o Cpk superior a 1.33 indica que tu proceso es capaz y cumple con las especificaciones. Si están por debajo de 1, el proceso necesita mejoras. Imagina un auto estacionándose en un garaje. Si el Cp es alto, el auto entra fácilmente sin tocar las paredes (dentro de las especificaciones). Si el Cp es bajo, el auto podría chocar, lo que indica que el proceso necesita ajustes. ??

Calculate standard deviations, ranges, and histograms. Peek at process capability indices (Cp, Cpk) like they’re gold purity tests. If Cp and Cpk sparkle, our process is 24-karat. If not, time to refine our methods. ??

In warehouse management, after calculations, analyze the results to identify variation sources and capability issues. Employ tools like fishbone diagrams, 5 whys, root cause analysis, and failure mode and effects analysis for a structured problem analysis. Compare these results with set benchmarks and goals to evaluate how well they are being met, enabling a targeted approach to addressing inefficiencies and improving process performance in the warehouse environment.

Analyzing the results of data collection is crucial for understanding process performance in construction projects. This involves using statistical tools to interpret data and identify trends, outliers, and areas for improvement. Techniques like control charts and process capability indices (Cp, Cpk) can provide insights into the stability and capability of your processes. By thoroughly analyzing these results, project managers can pinpoint inefficiencies, predict potential issues, and develop targeted strategies to enhance process reliability and overall project outcomes.

Para analizar los resultados cuando los índices Cp o Cpk no son adecuados, es fundamental utilizar herramientas que te ayuden a identificar la causa raíz del problema. Algunas: -Diagrama de Ishikawa (Espina de Pescado): Para visualizar y clasificar las posibles causas -Análisis de Pareto: Para identificar las causas más frecuentes. - AMFE (Análisis Modal de Fallos y Efectos): Para evaluar el riesgo asociado a las posibles causas. - Histogramas y Gráficos de Control: Para observar la distribución de datos y la estabilidad del proceso. Estas herramientas te permitirán profundizar en las causas de los problemas y tomar decisiones informadas para mejorar la capacidad del proceso.

Gather data like a treasure hoard. Are there outliers? Trends? Maybe the autoclave temperature dances the cha-cha during night shifts. Control charts (our process’s crystal ball) reveal secrets. Is the process hitting the bullseye or shooting arrows into thin air?

Implementar uma melhoria pode ser algo simples. O difícil é criar e consolidar um ambiente propício para que esta melhoria se sustente a longo prazo. Por exemplo, come?ar a implanta??o do 5S é mais simples, pois podemos movimentar as pessoas para organizar seu local de trabalho. Mas o grande desafio e mudar a cultura das pessoas, para que venham manter seu espa?o de trabalho organizado. Ent?o, se queremos ter melhorias consistentes, é preciso trabalhar a cultura das pessoas, pois se a cultura mudar, a sustenta??o da melhoria será algo natural para as pessoas.

Implement improvements based on your analysis using methods like brainstorming, experimentation, simulation, optimization, and design of experiments. Document and communicate these changes, ensuring they align with customer needs and expectations for effective and targeted process enhancement.

Channel your inner alchemist. Add a dash of automation, sprinkle in preventive maintenance, and stir with operator training. Kaizen vibes: Small, continuous improvements—like turning lead into gold, but less mythical. ??

Para implementar mejoras de manera efectiva, puedes usar un brainstorming para generar posibles soluciones. Luego, utiliza una matriz de priorización para evaluar y seleccionar las soluciones considerando impacto, costo y tiempo. Una vez priorizadas, es crucial desarrollar un Project Charter para la solución del problema, asegurando que el proyecto esté definido y alineado con los objetivos. No olvides incorporar el modelo ADKAR de Human Change Management para garantizar que el cambio sea adoptado con éxito en la organización. Además, realiza un mapeo de brechas con Process Change Management para identificar las diferencias entre el estado actual y el deseado, facilitando así una transición fluida y sostenible hacia la mejora implementada.

This is the phase where we should make sure the brainstorming activities are done by a team with diverse background. The diversity of the team members will allow a more complete brainstorming and the recommendations will be more thorough and rich.

After implementing improvements, consistently monitor and control your process. Continue gathering and analyzing data on process inputs and outputs, ensuring they meet desired limits and specifications. Use control charts and other tools to identify changes or trends in process variation and capability, taking corrective actions as necessary. Regularly update process documentation and standards, and actively seek feedback from customers and stakeholders to maintain and enhance process efficiency.

This might be the phase where one needs to reiterate the steps from definition to implementation as part of the monitoring and control phase. Environnement, situations, technologies, needs all can change over time. Hence, it’s important to reiterate the whole optimization phases over time in order to again improve and optimize the processes. Process optimization is a never ending project.
