Control Charts with Transformed Data
Partho replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins!
The assumption of normality in IMR (Individuals and Moving Range) control charts is indeed a common practice. However, it is true that in the real world, data often deviates from a perfect normal distribution. While transformed data can be used to address non-normality to some extent, its usefulness in checking process stability depends on various factors, including the nature of the transformation applied and the specific characteristics of the data. Transforming data involves applying mathematical operations to the original dataset to achieve a more desirable distribution or meet certain assumptions. Some common transformations include logarithmic, square root, and Box-Cox transformations. These transformations can help make the data more symmetrical and reduce skewness or variability. To illustrate the usefulness of transformed data for checking process stability, let's consider an example with 20 data points. Suppose we have collected data on the time it takes for a process to complete a certain task in min. Here are the analysis original data points: AHT1 25 30 32 31 29 27 30 28 33 26 24 28 34 40 45 42 50 38 35 30 First, lets perform the normality test and create an IMR control chart using the original data. Control chart was plotted using these data points and analyze the process stability based on the control limits and the presence of any out-of-control points Next, let's apply Logarithmic transformation to the data, perform the normality test and create a new control chart. The transformed data points are as follows: LOG AHT1 1.40 1.48 1.51 1.49 1.46 1.43 1.48 1.45 1.52 1.41 1.38 1.45 1.53 1.60 1.65 1.62 1.70 1.58 1.54 1.48 Interpretaion: By analyzing both control charts, we can assess the process stability based on the control limits and patterns in the data points. If the data points fall within the control limits, show no significant patterns, and exhibit randomness, the process is considered stable. In this example, both the raw and transformed data control charts show data points with same pattern. Therefore, we can conclude that there is no change in the process stability, even though the raw data was more skewed than the transformed data. The transformation allowed us to assess the process stability accurately. In this examples , though the moving range suggests process stability, one needs to understand the reason for shift in pattern along with the one data point that failed at point 17 in the individual chart. The point to remember is that the appropriateness of the transformation and the resulting interpretation depends on the specific context and understanding of the underlying process. It's always recommended to consult with subject matter experts and consider additional analyses if needed. In order to utilize an I-MR Chart, there is no mandatory requirement for the data to be always normal distributed, however extremely skewed data can cause some unwanted outcome including high false-alarm rates. If data appears skewed, we can investigate to see whether that is an indication of an out of control process or as per expectations for this type of process, and if expected, we can look for transformation of the data.- 8 replies

An I-MR Chart is a control chart which is used when data is in continuous category and is collected once at a time. It consists of two charts placed one over above, I Chart which is individual chart and MR chart is plotted for moving range which is absolute value of the difference between two consecutive points. Data following normal distribution is an assumption while drawing I-MR chart however in practical or real-world problem data doesn’t follow normal distribution all the time hence Process stability follows major role. I-MR charts are very sensitive to Normality of the data. Non-Normal data if considered as normal data can cause unexpected behaviors including false alarm rates and difficulty in identifying the special cause variation. If data is not normal, it is always advisable to do transformation using Box-Cox or Johnsons transformation to avoid the false alarm and get the right behavior of data for stability and control. A normal distribution may have the value from minus to plus infinity. In the real-world example this doesn’t occur physically very often. For example, Cycle time cannot be in negative numbers. Following is the Example for drawn I-MR charts when data is considered as normal however data is not normal and respective I-MR charts using data transformation: - Cycle time in Minutes: - Sl.No Cycle Time (In Minutes) S.No Cycle Time (In Minutes) S.No Cycle Time (In Minutes) 1 3196 11 267 21 322 2 241 12 302 22 147 3 372 13 518 23 774 4 42 14 554 24 185 5 481 15 566 25 556 6 6081 16 900 26 555 7 131 17 158 27 361 8 26 18 109 28 556 9 1445 19 167 29 898 10 363 20 51 30 170 Table 1 Probability Plot of dats Using Mini-tab Normality test for data in Table 1: - Normality test is done to illustrate whether data is normal or non-normal. I-MR Charts drawn in Minitab for Table 1 mentioned assuming data following Normal distribution: - The chart clearly illustrates that process is out of control, however out of control points are trigged due to false alarms I-MR Chart drawn in Minitab for Table 1 mentioned after transforming days using Box-Cox transformation: - The Chart clearly illustrates that process is in control, our of control data points mentioned earlier were due to false alarm in wrong assumption of data being normal.

In real world, the data rarely follows a normal distribution. Data is affected by outliers and measurement errors, because of which IMR chart may not be effective in detecting changes, as these charts assume that the data is normal. In such cases, we can use charts for non normal data or we can transform the data, depending on the scenario and the data type. Data transformation techniques, such as the Box-Cox or Johnson transformation, can help stabilize variances and make the data more symmetric, allowing for more accurate interpretations and applications of control charts. Data can also be split into rational sub groups and then buliding control charts on each split data. Checking for process stability using transformed data helps to identify potential problems in a process. By transforming the data, we can highlight any trends or patterns that might not be visible in the raw data. This can help us to identify potential causes of variation. Then corrective actions can be identified to improve the stability of the process and prevent any problems from re-occurring. Example: A call center will monitor the waiting times in the queue. If the data is not normal due to variability, then the distribution will be a non normal distribution and IMR chart may not accurately detect the actual problem or the trends. If the wait time data can be transformed, then the analysis on the data will be more accurate and will help the call center to take effective decisions.

If the data is not normal and is transformed, then that impacts the accuracy and validity of the control charts if in case they are to be monitored. This makes it important to handle the transformation of data in a more cautious way. There are no particular method of transformation that fits a particular scenario. Different method of transformation have different benefits. Some of the key considerations while choosing transformational techniques are, extent of non-normality prevalent in the data, how easy it is to apply the method, how much better is the interpretability of the data, how well the transformation supports the process performance and other factors. Its worthwhile to give due consideration of non-parametric method before considering the data transformation. Median charts, run charts, Weibull distributions are few methods that fit into non-parametric methods. Data smoothing is an approach that can assist in removal of noise from the data, clustering, binning and regression methods are part of noise removal approach. Data generalization is another approach of data transformation, where low level attributes are transformed to high level attributes. This is suitable in case if there are finite number of values in data that have large number of distinct values. Like in case of data set that has data for city, street, country and state, we can define hierarchy of these attributes by ordering them with respect to their relations. Order would be country, state, city and street. These are couple of customized data transformation as needed for specific scenario.

Control Charts with Transformed Data
Gitarchana Roy replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins!
IMR Control Charts is the most commonly used control charts which is a combination of the Individual and Moving range chart which helps us to analyse process stability and variability. It is used when we analyse continuous data and the data is normal. It is true that in the real world we seldom find normal data. In case of IMR charts, results will still be valid in case the data is moderately normal. The data can be transformed in case the data is non normal and highly skewed. The transformations can be done using either Box Cox Transformation, Logarithmic or Johnson’s Transformation. The data can be transformed and then appropriate control charts can be used to check on process stability Example:- 1. Usually time , effort and defect related data is non normal because the data can spread from 0 to infinite. One should investigate the data collection process and if MSA was done correctly before trying to transform data. Data transformation should be the last resort. Non parametric tests can also be used with non normal data. They usually analyse the median instead of the mean. However, it is possible that non parametric tests might not show the minor differences. In such cases data transformation is the only option left.- 8 replies

Control Charts with Transformed Data
Moushmi Kandori replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins!
Using IMR control charts for continuous data assumes that the data follows a normal distribution. If the data does not follow a normal distribution, using transformed data may be useful in verifying process stability. Transforming data can help to make the data conform to a normal distribution. For example, if the data is positively skewed, using a logarithmic transformation can help to normalize the data. Similarly, if the data is negatively skewed, a reciprocal or square root transformation may be used. Using transformed data can be useful in detecting process stability by identifying any patterns or changes in the data that may indicate a shift in the process mean or variability. For instance, if the control chart shows a trend or pattern with transformed data, it may indicate a shift in the process. In this case, further investigation may be required to identify the problem and take corrective action. For example, consider a manufacturing process that produces steel rods. The process involves heating and cooling the rods to achieve the desired tensile strength. The control chart for the tensile strength of the rods shows a trend with the raw data, indicating a possible shift in the process mean. However, after applying a logarithmic transformation to the data, the control chart shows no trend or pattern. This suggests that the process is stable and the raw data is not normally distributed. In another example, consider a call center that tracks the number of calls received per hour. The control chart for the call volume shows a shift in the process mean with the raw data, indicating a possible problem. However, after applying a square root transformation to the data, the control chart shows no shift in the process mean. This suggests that the process is stable and any concerns were due to the non-normal distribution of the raw data. In conclusion, while IMR control charts for continuous data are designed for normal distribution, transformed data can be useful in identifying process stability. If the transformed data shows no patterns or trends, it suggests that the process is stable, regardless of the distribution of the raw data. However, it is important to note that transformations should be used with caution, and the results should be interpreted carefully to avoid incorrect conclusions.- 8 replies

Control Charts with Transformed Data
Khalandar S replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins!
The IMR (Individuals and Moving Range) control chart is widely used to check the stability of a process over time and it is true that the IMR chart assumes that the data follows a normal distribution, but in reality, data often deviates from normal distribution. One approach to resolve such scenario is that data transformation techniques from non-normal to normal using various transformation techniques like Box-Cox transformation, logarithmic and square root transformations. After transforming the data, we can plot a control chart and check for process stability. But the limitation of this approach is that some transformations may not work well for certain types of data (If data set is either not well represented or contain outliers) which led to bias. Therefore, it is recommended to use transformed control charts as a replacement for traditional control charts. Transformed control charts can be useful in detecting process instability when normality assumptions are violated. However, it's important to note that transforming the data doesn't always guarantee that it will follow a normal distribution. Additionally, if the underlying process is non-normal, using a transformed control chart may not accurately reflect the true process behavior. In conclusion, using transformed data can be a useful tool for checking process stability when the underlying data is non-normal Some practical examples of transformed control charts are: 1. Manufacturing: A chemical manufacturing plant wants to monitor the concentration of a certain chemical in their production process. However, the data is highly skewed and does not follow a normal distribution. To address this, they apply a logarithmic transformation to the data and use an X-bar chart with transformed data to monitor the process mean over time. 2. Service: A software development team wants to monitor the number of bugs found in their code during each sprint. However, the data is highly skewed and does not follow a normal distribution. To address this, they apply a Box-Cox transformation to the data and use an individuals chart with transformed data to monitor the process variability over time. In each of these examples, transforming the data allows for more accurate monitoring of the process over time using control charts. It's important to note that choosing an appropriate transformation requires careful consideration of the underlying statistical properties of the data, as well as any practical implications for interpreting and acting on the results.- 8 replies

Moushmi Kandori replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins!
A collaborative strategy called "Way of Working" (WoW) concentrates on building successful work procedures within an organisation. It attempts to establish a pleasant work atmosphere that promotes growth and innovation and covers topics like communication, decision-making, and problem-solving. WoW is most closely tied to the Improve phase of the DMAIC (Define, Measure, Analyse, Improve, Control) framework. This phase entails putting new procedures into place in order to streamline operations, cut down on waste, and boost overall productivity. Businesses build a foundation that promotes a culture of continuous improvement by focusing on improvement opportunities through WoW practises. WoW supports an organization's culture of continuous improvement in a number of ways: 1. Promoting open communication: WoW promotes openness and encourages team members to openly discuss ideas, difficulties, and best practises, which results in a more collaborative workplace. 2. A focus on collaboration: WoW encourages synergistic teamwork by destroying silos, ensuring that everyone is working towards the same objectives. 3. Increasing adaptation: Teams in WoW learn to be proactive in their responses to shifting conditions while still being effective. 4. Fostering problem-solving abilities: Thanks to WoW's emphasis on proactive issue resolution and innovation, staff members become adept at seeing areas where they may strengthen either their individual or collective performance. 5. Creating learning opportunities: WoW encourages employees to continuously hone their skills through education and experience and supports their ongoing skill development. WoW helps foster continuous development inside teams and across the organisation as a whole by integrating these concepts into an organization's fundamental values, producing superior results for both people and enterprises. -

PriyankaBose replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins!
What is Way of Working (WoW)? Way of Working (WoW) refers to the specific practices, methodologies, and approaches that define how work is carried out within an organization. It encompasses processes, tools, principles, and cultural norms that guide employees in their day-to-day activities and decision-making processes. It encompasses various aspects depending on the organization's industry, size, and objectives, include (but not limited to): 1. Processes and procedures: WoW outlines the standardized processes and procedures that govern how tasks and activities are executed within the organization. It provides clarity on the steps to be followed, roles and responsibilities, and the sequence of activities involved in delivering products or services. 2. Methodologies and frameworks: WoW may incorporate specific methodologies, frameworks, or approaches that are used to accomplish work efficiently and effectively.

Performance metrics and measurement: WoW establishes the performance metrics, key performance indicators (KPIs), and targets that are used to measure progress and assess the success of work processes. It defines the criteria for evaluating performance and provides a basis for continuous monitoring, analysis, and improvement. 6. Training and skill development: WoW may encompass training programs and initiatives aimed at developing the skills and competencies necessary for employees to perform their work effectively. It includes training on specific tools, methodologies, or other relevant areas that contribute to the overall work processes. 7. Continuous improvement practices: WoW encourages a culture of continuous improvement by incorporating practices such as regular review, analysis, and feedback loops. It promotes a mindset of seeking opportunities for improvement, learning from mistakes, and implementing changes to enhance processes and outcomes. The goal of establishing a well-defined Way of Working (WoW) is to create consistency, efficiency, and effectiveness in how work is conducted throughout the organization. It provides a common understanding of expectations, processes, and outcomes, enabling employees to align their efforts and collaborate more effectively. By having a clearly defined Which phase of DMAIC is this most closely related to? In the context of process improvement methodologies, "Way of Working" (WoW) is not a specific term or phase within the DMAIC framework. However, while the Way of Working (WoW) is not explicitly associated with a specific phase of DMAIC, it refers to the overall approach, methodologies, and practices that an organization follows to conduct its work/ processes. It includes the standard operating procedures, guidelines, and cultural norms that shape how work is carried out in organisations. A strong WoW aligns with the principles of continuous improvement and can support the DMAIC framework by providing a structured and disciplined way of conducting process improvement projects. Hence, WoW is may be looked at as closely related to the Improve phase of the DMAIC framework. The Improve phase focuses on identifying and implementing solutions to address the root causes of process inefficiencies and deviations from desired performance. How does it help create a culture of continuous improvement in an organization? It is evident that WoW helps create a culture of continuous improvement in an organization in several ways: · Standardization: WoW promotes the standardization of processes and procedures, ensuring consistency and reliability in how work is performed. This allows for easier identification of areas for improvement and comparison of performance across different teams or units. · Collaboration: WoW encourages collaboration and cross-functional cooperation. By establishing clear communication channels and fostering teamwork, employees can share knowledge, insights, and best practices, leading to more effective problem-solving and continuous learning. · Data-Driven Decision Making: WoW emphasizes the use of data and metrics to drive decision making. It encourages employees to collect and analyse relevant data to identify trends, patterns, and areas of improvement. This data-driven approach enables more informed decision making and helps prioritize improvement initiatives based on their potential impact. · Continuous Learning and Experimentation: WoW supports a mindset of continuous learning and experimentation. It encourages employees to be open to new ideas, try out innovative approaches, and learn from both successes and failures. This iterative process allows for continuous improvement and adaptation to changing circumstances. · Employee Empowerment: WoW empowers employees by giving them the necessary tools, knowledge, and authority to make improvements in their own work areas. This sense of ownership and empowerment fosters engagement and motivation, as employees feel empowered to contribute to the organization's overall improvement efforts. Outcome Establishing a culture of continuous improvement through a well-defined Way of Working (WoW), organizations can expect to, · Foster a mindset of improvement: A clear WoW that emphasizes continuous improvement helps employees understand that seeking ways to enhance processes and outcomes is an integral part of their work. It encourages them to constantly question the status quo and look for opportunities to make incremental or breakthrough improvements. · Encourage collaboration and knowledge sharing: An effective WoW promotes collaboration among employees, enabling them to share best practices, lessons learned, and innovative ideas. This exchange of knowledge and experiences enhances problem-solving capabilities and accelerates improvement efforts across the organization. · Standardize processes and reduce variability: A well-defined WoW includes standardized processes and procedures that promote consistency and reduce process variability. This standardization enables better control over operations, easier identification of deviations, and opportunities for improvement. · Emphasize data-driven decision-making: A strong WoW encourages the use of data and metrics to drive decision-making. It promotes the collection, analysis, and interpretation of data to identify trends, root causes, and improvement opportunities. This data-driven approach enhances the accuracy and effectiveness of decision-making, leading to more impactful improvements. · Empower employees: An effective WoW empowers employees by providing them with the necessary tools, resources, and authority to contribute to process improvement initiatives. It encourages them to take ownership of their work, experiment with new ideas, and contribute to a culture of continuous learning and growth. Overall, WoW helps create a culture where continuous improvement becomes ingrained in the organization's DNA. It promotes a proactive approach to problem-solving, a focus on efficiency and quality, and a willingness to challenge the status quo. By embedding these principles into the organization's way of working, it becomes a natural part of the organizational culture and leads to sustained improvements over time. Conclusion: While WoW and DMAIC are not directly correlated, organizations can leverage a strong WoW to support the DMAIC framework and create a culture of continuous improvement. -

Ways of working is also known a Ground rules, working agreements, shared expectations etc. It describes the team's set of expectations for participation & collboration to achieve organization goals. It includes standardized processes, tools and behvaiours that are designed & developed to improve quality, efficiency & collaboration. In DMAIC methodology, WoW is most closely related to Improve phase, which focus on action planning & Implementation to fix the root cause of a problem. WoW helps to create a culture of continuous improvement in an organization by providing framework on following priciples. Standardized Processes and Workflow: Standardized processes and workflows ensure that everyone understands how work is done and how different activities are interconnected. Visual management tools like Standard work (Task Instruction Sheet(TIS)), Kanban boards, Gantt charts, Value stream Maps etc., can help provide transparency and clarity. Continuous Learning and Improvement: Embracing a culture of continuous learning and improvement is vital for a successful way of working. Encouraging experimentation, sharing lessons learned, and providing opportunities for professional development foster a growth mindset and drive innovation. Well defined Goals and Objectives: Having clear & well defined goals provide a sense of direction and focus for the work to be done that align with the overall purpose and strategy of the organization. Continuous Alignment with Strategy: The way of working should be aligned with the overall strategy and objectives of the organization. Perodical reviews and updating the SOP's as per best work practices to ensure they remain in line with the strategic direction Communication and Collaboration: Effective communication plays important role in creating successful collaboration and teamwork within organization. It involves active listening, sharing information, providing 360 deg feedback, clear and open lines of communication. Agile and Adaptive Approach: Many organizations are adopting agile methodologies to enhance their way of working. Agile emphasizes flexibility, iterative development, and continuous improvement. It enables teams to adapt to changing circumstances, respond to customer needs, and deliver value incrementally. Regular Evaluation and Feedback: Regularly evaluating progress, providing feedback, and conducting performance reviews are important aspects of the way of working. This helps identify areas for improvement, recognize achievements, and ensure alignment with goals and expectations. Efficient Use of Tools and Technology: Utilizing appropriate tools, technology, and automation can streamline workflows, improve efficiency, and enhance collaboration. It's important to assess the needs of the organization and choose tools that support the specific work processes. In summarized way, an Organization's Vision & Values describe breifly about it's way of working. Remember that, The way we orgnize our team depends on type of work we do. Hence, the Way of Working may vary across organizations and teams based on KPI's & business requirements, and it is important to customize the above priniciples to suit specific contexts and requirements. -

A top-down diagram, also known as a top-level diagram or system hierarchy diagram, is a graphical representation that illustrates the overall structure or hierarchy of a system or organization. It provides a high-level view of the system's components and their relationships, showing how the system is organized from a top-level perspective. In a top-down diagram, the system or organization is depicted as a single entity at the top, and then it is progressively decomposed into smaller subsystems or components as you move down the diagram. This decomposition represents the hierarchical relationship between the various elements of the system. This diagram typically uses boxes or rectangles to represent the different components or subsystems, and lines or arrows to show the relationships or connections between them. The higher-level components are placed at the top of the diagram, and the lower-level components are placed below, indicating their position in the hierarchy. Top-down diagrams are often used in system analysis, software development, project management, and business process modeling. They help stakeholders understand the overall structure and organization of a system, providing a visual representation that aids in communication, planning, and decision-making. They can be used to identify subsystems, dependencies, and interfaces, as well as to guide the decomposition of a complex system into manageable components for further analysis or development. It can be a useful tool in a DMAIC (Define, Measure, Analyze, Improve, Control) project. Let’s consider a DMAIC project aimed at reducing Average Handling Time (AHT). Here are a few ways in which a top-down diagram can be applied in such a project: Process mapping: Use the top-down diagram to map out the current process flow for handling customer interactions. Start with the high-level process steps and then break them down into sub-processes or tasks. This will help identify areas of inefficiency or bottlenecks that contribute to higher AHT. Root cause analysis: Once you have identified the key process steps contributing to AHT, use the top-down diagram to analyze the root causes of delays or inefficiencies within each step. Break down each step further into its constituent activities or factors that influence AHT. This will help in identifying specific causes that can be targeted for improvement. Impact analysis: Use the top-down diagram to assess the impact of potential improvement initiatives on AHT. When considering changes or solutions, break down the proposed changes into their individual components and assess how each component affects the overall process. This analysis can help prioritize improvement efforts and focus on the most effective interventions. Control plan development: A top-down diagram can aid in developing a control plan to sustain the improvements achieved. After implementing changes and reducing AHT, use the diagram to identify control points and monitoring mechanisms. Break down the process into checkpoints and define key performance indicators (KPIs) to ensure AHT remains within acceptable limits over time. Communication and collaboration: A top-down diagram provides a visual representation of the process and facilitates communication and collaboration among team members involved in the DMAIC project. It helps in aligning everyone's understanding of the current process and improvement goals, allowing for better coordination and teamwork. Just to remember, a top-down diagram is just one of many tools that can be utilized in a DMAIC project. It should be complemented by other tools such as process flowcharts, data analysis techniques, statistical tools, and more, depending on the specific needs and challenges of the AHT reduction project. Here are a few more examples of how a top-down or hierarchical diagram can be used in DMAIC project for different scenarios: Manufacturing Defect Reduction: In the Define phase, a top-down diagram can be created to visualize the overall manufacturing process. It would start with high-level steps like raw material procurement, production, inspection, and shipment. Each step would be broken down into subprocesses such as material handling, machining, assembly, quality control, and packaging. This diagram helps understand the end-to-end manufacturing process and provides a foundation for further analysis and improvement. Customer Complaint Handling: When addressing customer complaints in the DMAIC project, a top-down diagram can be used to map the complaint handling process. Starting with the initial complaint intake, it can be broken down into steps like complaint registration, investigation, root cause analysis, corrective action, and resolution. Each step can then be further detailed with subprocesses, responsibilities, and information flow. This diagram helps identify bottlenecks, inefficiencies, and opportunities for improvement. Order Fulfillment Cycle Time Reduction: To reduce order fulfillment cycle time, a top-down diagram can be created to represent the end-to-end order processing workflow. It would begin with steps such as order receipt, order verification, inventory check, order picking, packing, and shipping. Each step can be further decomposed into subprocesses like data entry, system checks, coordination with warehouses, and logistics. The diagram helps identify areas where cycle time can be minimized by optimizing individual steps or eliminating non-value-added activities. Employee Onboarding Process Improvement: In the context of improving the employee onboarding process, a top-down diagram can be used to break down the process into its constituent parts. Starting with high-level stages like pre-employment, orientation, training, and integration, each stage can be further divided into specific activities such as background checks, paperwork completion, system access setup, and departmental onboarding. The diagram helps identify areas where the onboarding process can be streamlined, standardized, or automated. Invoice Reconciliation Accuracy Enhancement: For improving invoice reconciliation accuracy, a top-down diagram can illustrate the invoice reconciliation process from start to finish. It would include steps such as invoice receipt, data extraction, matching with purchase orders, validation, exception handling, and final approval. Each step can be broken down into subprocesses like data entry, data validation, system checks, and reconciliation reporting. The diagram helps identify areas where errors commonly occur, allowing for targeted improvement efforts. In these examples, the top-down diagrams provide a visual representation of the processes, highlighting their components and relationships. They serve as a basis for analysis, problem identification, improvement planning, and collaboration among team members. -

A Top-Down Diagram / Flowchart helps to visualize a process by listing down the main process steps and the sub steps listed below the main process steps. This helps to understand the entire process or problem at hand and identify the improvement opportunities. This can be used in the various DMAIC phases in a Six Sigma Project. Define phase to: · Define the problem in a hierarchical and structured manner · Understand the process / problem at hand Measure phase to: · Identify primary and secondary KPIs / measurements Analyze phase to: · Understand the areas of process improvement by analyzing all the processes and the sub processes. · Identify the most probable causes and conduct root cause analysis. Improve phase to: · Implement improvement actions in the necessary sub processes and processes so that the overall improvement can be analyzed. Control phase to: · Make necessary process changes and analyse it’s impact in a systematic manner. -

A Top Down Diagram is a visual representation of a process, system, or organization from a high level. It displays the relationships between the many parts or systems as well as the overall structure. The method of creating the diagram begins with the major elements, which are then divided into more manageable sub-elements until the complete system or process is properly depicted. Systems can be planned and designed using top-down diagrams as well. It can be simpler to understand how the many components of a system will fit together and interact if you start with the broadest elements and work your way down to the more precise ones. Top-down diagrams are an effective tool for planning, understanding, and designing systems. A top-down diagram can be applied in a variety of ways to a DMAIC project. It may be utilized for: · Define the project's overarching objective. · Divide the objective into smaller, easier to handle tasks. · Monitor the project's development. · Note any potential issues or dangers. · Share the project plan with all relevant parties. Industry illustration : A high level top-down representation of a medical claims process that is up for audit is shown in the figure below. The procedure displays the claims that have been received, which the users verify to determine the auditable expenditures, which in turn go through many phases to generate the net income for a specific claim. This can be an effective technique to comprehend how a complicated system operates and to pinpoint the various components that must cooperate for the system to operate as intended. -
