Let's discuss how Artificial Intelligence (AI) can be a game-changer in our Lean Six Sigma projects, specifically within the DMAIC framework (Define-Measure-Analyze-Improve-Control)

Unearthing Hidden Gems in the Data (Analyze):

One of the biggest headaches in Six Sigma can be data analysis. Traditionally, it's a time-consuming slog through mountains of information. AI, however, can be our secret weapon. Imagine this: we're tackling inefficiencies in the customer service department. We used to spend weeks manually combing through call logs and surveys. Now, with AI-powered tools, we can unleash machine learning algorithms that analyze this data in a flash. These algorithms can uncover hidden patterns and trends that we might miss, like subtle shifts in customer sentiment or recurring pain points.

A Use Case:

A large bank was using AI in the Analyze phase of a project focused on loan application processing times. The AI tool identified a correlation between incomplete applications and longer processing times. This insight allowed them to streamline the application process and significantly reduce processing delays.

Supercharging Root Cause Analysis (Analyze):

AI can also be a powerful ally in the Analyze phase when it comes to root cause analysis. Traditionally, this might involve brainstorming potential causes and then manually testing each one. AI, however, can analyze vast datasets and identify the most likely root causes, saving us valuable time and effort.

A Use Case:

In a manufacturing company, they were experiencing a high rate of product defects. During the Analyze phase, they used an AI tool to analyze data from sensors on the production line. The AI identified a subtle temperature fluctuation that was causing inconsistencies in the product. By pinpointing the exact issue, they were able to implement a targeted solution and dramatically reduce defects.

The Takeaway: AI as Our Partner, Not Replacement

These are just a few examples of how AI can be a valuable asset in our Lean Six Sigma toolbox. It can free us from tedious tasks and empower us to focus on the bigger picture, like developing and implementing effective solutions. Remember, AI is here to build up our skills, not replace them. It's like having a super-powered data analyst on our team, helping us make data-driven decisions and achieve those Six Sigma goals even faster.

To answer this question, we need to understand that the DMAIC methodology is nothing but mindfulness and data driven solution identification for a problem. Thus, ideally this must have data to understand the problem, analyze it and identify root causes, improve through suggestions and validate once executed. Statistics is very helpful in understanding the problem and root causes. And wait a minute, this can be taught to the machine. Yes?

 

Now a project is typically done by constituting a team of experts, who need to resolve this problem over and above their day-jobs. This manning of staff on a project makes it a time consuming, and expensive problem identification and resolution process.

 

If we understand these key aspects of the DMAIC project, it will be fairly easy to understand that Measure, Analyze, and Control Phase can all be done better with technology, with AI/ML driven algorithms to understand and analyze newer trends and patterns in real time and ensure that we deliver on the overall aspects of cost savings, productivity enhancements, and sustainability benefits of using lesser earth resources; and without manning these projects separately. We will still need Subject matter experts to help with approving the improvement, or execution in sub/super systems etc. That is also because as of now, in learning phase, we need to train AI to ensure our learnings are embedded into the systems.

 

All right, going to use cases now:

Case 1 - Predictive maintenance :

 

1- In aviation industry, we have tons of data driven systems, some of them have hard life for change, others have continuous monitoring and we need to replace parts and systems as per their behaviour. In this case, having a digital twin, and analyzing how system is behaving at all points in time outside the actual monitoring on the aircraft, to understand trends and patterns and predict the possible next steps is crucial.

 

2- Likewise, think about the same on a train or metro. 

 

3- Think about this on construction site where we have tons of expensive assets helping us day in and day out. If we can understand the deterioration better, we can do predictive maintenance and prevent the possible downtime on account of arranging the maintenance work and loss of productivity.

 

4- Think of the same in machining environment for producing sheet metal parts, doing milling, CNC machines etc.

 

Case 2 - Inventory management & Control:

5- Across industries, inventory management and control is a negative sum game. No matter how many suppliers are on contract basis, no matter whether we have SAP, or other ERP systems, we fail when we have an unseen change in supply-demand. Each case brings in its own challenges, and teams can't face these challenges with any historical reference. Assume a system that has understanding of various epidemics, financial crashes, seasonality trends, minor changes in supply chain issues etc and how much really we should stock now to prevent a furture stock out; and how much less should we order than what we are currently ordering.

ML/AI will have a great role to play here. We already see ML driven Inventory ordering systems in use across industries.

 

Case 3 - Troubleshooting

6- In industries, it is a challenge to understand what part finally fixed the problem. With ML/AI driven solutions, we can have a more realistic understanding of what % of problem is solved by Path A or Path B or Path C if each of these paths can be taken to resolve the same fault.

Now extend this across industries - whether it is television, or your washing machine or an automobile, or F1, or train or aircraft.

 

The progressive drive to improve has the next action item of ensuring the data visibility is not on need based, but is continuous. AI/ML support is not a choice, it is already becoming a default. The key is for various teams to imbibe these skill sets together, and understand how to optimize resources better and deliver faster and more efficient outcomes.

Following are specific use cases for Lean Six Sigma DMAIC process where artificial intelligence can be utilized effectively:

 

        Define :

 

• If a company receives thousands of customer feedback forms monthly. Using AI-based sentiment analysis, they can automatically categorize feedback into positive, negative, and neutral sentiments. They can then check common issues.
• A finance company can streamline its loan processing process. Using OCR technology, AI can extract data from paper-based loan applications and automatically convert into digital forms, reducing manual entry errors and improving data accuracy.  

 

        Measure :

• A finance company wants to streamline its loan processing process. Using OCR technology, AI can extract data from paper-based loan applications and automatically convert into digital forms, reducing manual entry errors and improving data accuracy.

      Analyze :

 

• A company experiences a high rate of defects in one of its production lines. By applying machine learning algorithms, they analyze historical production data to identify patterns and correlations that point to the root causes of defects.

 

      Improve :

• A car manufacturer uses AI-driven optimization algorithms to adjust the assembly line processes dynamically. The AI system analyzes real-time data and adjusts the workflow to minimize bottlenecks and maximize efficiency.

 

     Control :

 

• A customer service center uses AI to monitor call handling times, customer satisfaction scores, and agent performance in real-time. The AI system then provides immediate feedback and suggestions to agents which helps them to maintain AHT and Quality.

 

Integrating AI into Lean Six Sigma DMAIC projects allows organizations to leverage advanced data analytics, automation, and predictive capabilities to drive more effective and efficient process improvements.

    

Nowadays, AI play big role in all live experience. In this sense, it could be used to increase accuracy and accelerate steps in lean six sigma.

Going through DMAIC steps, it’s easy to establish that in the:

-          Define phase, AI could be used helping on problem statement establishment with SMART objective in a effective way; screening and analysing stakeholder for better management of their expectation and satisfaction.

 

-          Measure phase, AI could help automating data collection accurately elimination human bias and errors

 

-          Analyse phase, AI could be very effective in pattern detection and Root Cause Analysis while avoiding human bias and errors.

 

-          Improve phase, AI could as well help shaping a robust and power simulation model, and optimising algorithms for process improvement

 

-          Control phase, AI could help in very effective way on real time monitoring system setting, continuous learning and process adaption overtime and predicting failure with very accurate maintenance planning.

 

All those advantages show us that AI is very linked to Lean Six Sigma and could help  reduce DMAIC time while having accurate and sustainable results

Artificial Intelligence is a cutting-edge technology shaping the world around us on an unprecedented pace. By 2027, 85M jobs are expected to be displaced globally because of AI, and 60% of employees will need reskilling or upskilling. At the same time, AI will not replace scientists, lawyers, actuaries or consultants. Scientists, lawyers, actuaries and consultants who use AI
will replace those who do not.  AI phases appear linear; in fact, disruption will occur when someone leapfrogs legacy ways of working to make an industry-wide impact.

 

AI like internet has enormous potential to transform our lives in many aspects. It can be very well used in a Lean Six Sigma DMAIC project, below are phase wise potential uses and some of the Use Cases:

 

Define – Using GEN AI (preferably an in-house developed) elements like Business Case, Problem Statement from Project Charter can be enhanced without spending too much time along with a recommended list of CTQs by learning from and extrapolating existing datasets. It can also help to refine or perform a thorough Project Risk Assessment provided a specific Prompt is given.

 

Measure – Its always better to have an additional mind and here we can leverage the GEN AI linked to years of data base from different clients, services, practices and regions to generate ideas about a specific business problem along with prioritization. GEN AI can also help to generate / estimate Sample Size, Sigma Level and Process stability following SPC principals by providing right set of data and specific commands.

 

Analyze – In this phase Gen AI can help to establish initial Hypothesis and Predictive Analytics can help us verify them by analyzing historical and real-time data to forecast future events, trends, or behaviors, enhancing decision-making and strategic planning. This can help us to narrow down a list of potential factors to vital few significant factors.

 

Improve – GEN AI can be used to generate possible solutions or refine / prioritize the ideated solutions. There are number of solutions that can be developed using AI for given business problems. Some of the examples as below:

 

Contact Center and Front Office:

GPT can be used to help customer support staff answer real time complex questions to customer

Copilot can help to generate after call notes

Predictive Analytics can help identify a Caller who has the potential for being a Repeat Customer or also can highlight and prioritize a Repeat Customer

AI can also be used to for call audits, feedback and colleagues coaching / feedback with minimal human intervention

Besides these AI can also be used for Virtual Agents who perform tasks, make decisions, interact with their environment independently, based on programming and learned experiences, without human intervention.

 

Business Development:

GEN AI can be very helpful to perform Client study / analysis before a RFP an also to generate RFP responses if it is linked with a rich data source. This could save a lot of time of Client Facing colleagues which could be used for other more value add works.

 

HR:

GEN AI can be very useful in creating Job Architecture and Job Description besides using historical and real-time data to forecast future events, trends, or behaviors, enhancing decision-making and strategic planning.

 

Client Administration:

Sound OCR tool combined with Predictive Analytics and GEN AI can be used to automatically process and integrate synthesized or enhanced data from various sources into a central system, improving data quality and insights for faster and better decision making.

 

 

There could be many more Use Case for GEN AI even in the field of Legal, Medical Science or Hospitality industry. What we have seen for now is the tip of iceberg and sky is the limit.

GEN AI along with Predictive Analytics using historical and real time data can help differentiate the Significant Improvements / Solutions from the trivial ones.

 

Control:

GEN AI and Predictive Analytics can help us assess the sustainability of improvements in this phase using historical and real time data. GEN AI can also help us identify key Risk areas around the improvement and recommend sound controls around them given specific prompts. It can also help design robust Change Management plans given it is linked to decent data sources and provided specific prompt.

 

At the end GEN AI can also suggest other parts of businesses where the best practices from a given project can be leverage with little tweaks.

Very interesting answers from all participants. Some of the answers could not be published as they either failed the AI generated content or plagiarism checks. 

 

While reviewing the answers, I got a sense that some of us feel that AI has this super power to replace everything  While time will tell whether it is true or not, for the time being thankfully there are many things that AI can still not do!
