How to Generate Possible Solutions in the Improve Phase of Six Sigma DMAIC Process

The Six Sigma Improve phase needs smart thinking for coming up with good ideas. These ideas should help make customers happier, save money, and fit well with the company's ways of working. A tool you can use to sort your ideas is a "prioritization matrix" which ranks each idea based on certain rules. All solutions should have specific goals and should be something that can really be done within a set time. This may sound like a tall order, but it's key to making sure your Six Sigma project really works. Expect to find these strategies useful as you delve deeper into finding the best way forward.

To effectively generate possible solutions in the Improve phase of a Six Sigma project, it is crucial to involve those affected by the problem and experts in the subject matter. Techniques such as brain-writing, benchmarking, assumption busting, creative brainstorming, and modified brainstorming can be valuable tools for idea generation during this phase. Utilizing these techniques will aid in synthesizing potential solutions and selecting the most viable option for implementation.

Prioritizing Potential Six Sigma Solutions

In the Improve phase of Six Sigma, once you've pinpointed several potential solutions, it's crucial to prioritize them effectively. This involves evaluating each solution based on certain criteria, which helps you determine which solution to focus on first. One common approach is using a prioritization matrix, allowing you to rank potential solutions based on predefined parameters.

A prioritization matrix usually entails establishing specific evaluation criteria like impact on customer satisfaction, cost-effectiveness, and compatibility with existing processes. Each potential solution is then assessed against these criteria and given a score or ranking. By using this approach, you gain a clear understanding of which solutions align best with your organization's overall goals.

When assessing impact on customer satisfaction, factors such as the solution's ability to improve product quality, enhance service delivery, or streamline customer interactions come into play. Cost-effectiveness encompasses not just the direct financial implications but also the long-term benefits and potential savings linked to the solution. Compatibility with existing processes is essential for seamless integration and minimal disruption.

Let's say your team has generated three potential solutions: Solution A, B, and C. Using a prioritization matrix, you assign scores to each solution based on their impact on customer satisfaction, cost-effectiveness, and compatibility with existing processes. Evaluating these elements allows you to make an informed decision about which solution provides the most value to your organization.

Keep in mind that different projects or organizations may have unique criteria for evaluating potential solutions based on their specific needs and priorities. Therefore, it's essential to customize the prioritization matrix accurately.

Effectively prioritizing potential Six Sigma solutions is a critical step in ensuring that your improvement efforts yield maximum impact and align with your organization's strategic objectives. By carefully evaluating solutions based on defined parameters such as customer impact, cost-effectiveness, and process compatibility, you can focus your resources on implementing solutions with the highest potential for success.

Transitioning from generating possible solutions to establishing effective criteria is vital for realizing impactful outcomes in the Six Sigma journey.

Six Sigma DMAIC Process - Improve Phase - Generate Possible Solution

Involve those who will be Affected: We need to make sure we solicit the upfront involvement of People affected by the problem or its solution and People with expertise in the subject matter. We should then Focus on the Root Causes i.e. Make the affected parties revisit the significant root causes to get to a solution. Then, pick on Idea Generation Technique.

Five key techniques used for idea generation and synthesis are:

  1. Brain-writing
  2. Benchmarking
  3. Assumption Busting
  4. Creative Brainstorming
  5. Modified Brainstorming

Idea Generation Technique - Brain-writing

Brain-writing is a technique used to generate many ideas in a short period of time. Two key modified brainstorming techniques used are Brain-writing 6-3-5 and Constrained Brain-writing.

Brain –writing 6-3-5 - The name brain-writing 6-3-5 comes from the process of having 6 people write 3 ideas in 5 minutes on a pre-defined parameter.

Constrained Brain-writing: The name constrained brain-writing comes the fact that on certain occasions the team may want to have a set of constrained ideas around a pre-determined focus, rather than ranging freely.

Idea Generation Technique - Benchmarking

Process benchmarking is a technique of continually searching for the best methods, practices and processes, and either adopting or adapting their good features and implementing them to become the “best of the best”.

Idea Generation Techniques – Assumption Busting

Assumption busting as a technique is used to trace back from the current performance problems to identify rules and then surface underlying assumptions.
The key steps involved in assumption busting are:

  • Revisit the current problem at hand.
  • Identify the rule(s) responsible for the problem.
  • Trace the rule(s) back to an assumption in the process.
  • Test to break the assumption – Is it wrong from the start? Or, Can it be made untrue?

For example: In a personal loan approval process the problem is lengthy cycle time for approvals which is leading to dissatisfaction. Investigation of the process reveals that there is a rule existing in the process which makes every vital task in processing the loan pass through a specialist (legal expert, financial expert, credit expert) after it has been processed by an agent. The reason for rule existing in the process is an assumption which says that all loan deals are complex. On investigation and data-collection it is found that only 5% of deals are complex and thus the process assumption is wrong.

Idea Generation Technique – Creative Brainstorming

Nominal Group Technique: The nominal group technique is a structured method to narrow down & prioritize on a list of choices. It is called “nominal” because during the session the group doesn’t engage in the usual amount of interaction typical of a team. Because of this relatively low level of interaction, nominal group technique is an effective tool when some group members are new to each other, relatively low level of interaction is required, issues are of highly controversial nature and a team is stuck in disagreement.

Idea Generation Technique – Modified Brainstorming

Modified brainstorming technique makes some basic and/or simple amendments to the “regular” creative brainstorming in order to help expand the number and quality of ideas. Three key modified brainstorming techniques used are: Analogy Technique, Channeling Technique and Anti-Solution Technique.

Analogy Technique: The ideas generated on the “analogy” then get translated to the real situation (the problem at hand).

Channeling Technique: We begin by listing “categories” of ideas for the issue at hand. Then, as the team brainstorms, over a period of time it can “change channels” when new ideas slow down. The objective is to capture a broad range of ideas (several channels), as well as of quantity (as many ideas as possible in each channel).

Anti-Solution Technique: We begin by brainstorming around the opposite of the issue at hand. This is probably the easiest of modified brainstorming methods. For example, rather than brainstorming on ways to ensure complete information on a personal loan form we brainstorm on how to ensure we get no/incomplete information on the personal loan form.

Criteria for Establishing Six Sigma Solutions

When identifying potential solutions in the Improve phase of Six Sigma, it's crucial to have stringent criteria in place to evaluate and assess their validity. The selection and establishment of these solutions often align with the principles of being Specific, Measurable, Achievable, Relevant, and Time-bound—commonly known as SMART criteria.

Let's break down the SMART criteria:
  • Specific: The solution should be clear-cut and well-defined, leaving no room for ambiguity or misinterpretation.
  • Measurable: There should be a quantifiable method to measure progress and determine the degree of success achieved once the solution is implemented.
  • Achievable: The chosen solution should be realistic and attainable within the given resources, capabilities, and time frame.
  • Relevant: The solution must directly address the identified problem or opportunity for improvement.
  • Time-bound: Establishing clear timelines and deadlines for implementing the solution is crucial.

For instance, imagine a manufacturing company aiming to reduce product defects. An effective Six Sigma solution following the SMART criteria might include specific targets for defect reduction (e.g., reducing defects by 20% in 6 months), measurable quality metrics to track progress (e.g., defect rate per thousand units), achievable process improvements aligned with available resources, relevant training programs for employees, and a time-bound action plan with milestone deadlines.

By adhering to these SMART criteria when establishing potential Six Sigma solutions, organizations can ensure that their efforts are focused on practical, impactful, and achievable objectives. This deliberate approach not only enhances the clarity and effectiveness of selected solutions but also contributes to the overall success of improvement initiatives.
Now, let's explore the various robust techniques used for idea generation through Six Sigma tools.

Idea Generation through Six Sigma Tools

Generating ideas is an exciting step in the process of improving a business. Think of it as grabbing a bunch of puzzle pieces and figuring out how they fit together to create a clear picture. In the world of Six Sigma, idea generation tools are like colorful puzzle pieces that help teams piece together innovative solutions to complex problems.

One such tool is brainstorming. This technique invites diverse perspectives by gathering a group of people from different areas of expertise to generate as many ideas as possible. The brainstorming session doesn't just produce ideas; it's about encouraging creativity and free thinking without judgment, which often leads to a breakthrough solution that might not have been considered by an individual working alone.

Next up, we have affinity diagrams. These are like organizational wizards that help make sense of the chaos of ideas generated during brainstorming. Affinity diagrams facilitate the categorization and consolidation of these ideas into logical groups based on their similarities or themes. By doing this, teams can identify patterns and connections that might have been otherwise overlooked.

Moreover, the Theory of Inventive Problem Solving (TRIZ) is another powerful technique used in Six Sigma. TRIZ introduces a structured approach to problem-solving by analyzing patterns of problems and solutions, and using inventive principles to propose innovative ideas.

Imagine you're part of a cross-functional team aiming to improve the efficiency of a manufacturing process. During a brainstorming session, one team member suggests rearranging the sequence of production steps—this prompts others to come up with related ideas on optimization and resource utilization. Using affinity diagrams, the team organizes these suggestions into categories such as "Workflow," "Equipment Upgrade," and "Skill Training." This visual representation helps the team identify common threads across the suggestions and prioritize which areas need immediate attention.

In another case, the TRIZ method sparks inventive problem-solving by presenting generalized solutions used in various contexts that can be tailored to address specific issues within the manufacturing process.

By incorporating these powerful tools into the Improve phase of Six Sigma, organizations can tap into a rich reservoir of creative solutions that have the potential to revolutionize their processes and drive continuous improvement.

In this quest for continuous improvement, it's crucial to evaluate and measure Six Sigma solutions to ensure their effectiveness and impact. Let's now turn our attention to exploring methods for evaluating and measuring the success of these implemented improvements.

Evaluating and Measuring Six Sigma Solutions

After identifying potential solutions, it's crucial to evaluate and measure their effectiveness. This requires using data-driven metrics and Key Performance Indicators (KPIs) to assess how well the proposed solutions align with the project goals and organizational objectives. These metrics are vital in determining whether the solutions will lead to tangible improvements in quality, cost reduction, efficiency, and customer satisfaction.

One of the fundamental techniques used in evaluating Six Sigma solutions is Statistical Process Control (SPC). SPC involves monitoring and controlling a process through the use of statistical methods to ensure it operates efficiently and within specified limits. By employing SPC, teams can detect variations in a given process, allowing them to take corrective actions before defects occur or quality standards deviate from the target.

Control charts play a significant role in SPC by providing a visual representation of how a process changes over time. These charts help in identifying any patterns, trends, or shifts that may affect the performance of a specific process. Analyzing control charts allows teams to make informed decisions about the stability and capability of processes, aiding in the assessment of solution effectiveness.

Additionally, it's crucial to establish clear Key Performance Indicators (KPIs) that align with the defined project goals. KPIs provide measurable criteria that reflect the success or effectiveness of a solution. They enable teams to track progress, identify areas that require improvement, and make data-informed decisions throughout the implementation phase.

For instance, if a key goal is to reduce customer complaints related to product defects, relevant KPIs might include the percentage reduction in reported defects, customer satisfaction ratings post-implementation, and the decrease in warranty claims. These KPIs are quantifiable measures that allow teams to gauge the impact of the implemented solutions on customer experience and product quality.

Moreover, post-implementation analysis is crucial for validating the effectiveness of the selected solutions. This involves comparing pre-implementation baseline data with post-implementation performance data to ascertain any improvements. The comparison helps in understanding the magnitude of change brought about by the implemented solutions and whether they have successfully addressed the identified root causes.

By employing robust evaluation techniques such as Statistical Process Control (SPC), control charts, and defining relevant Key Performance Indicators (KPIs), organizations can effectively measure and assess the impact of Six Sigma solutions on process performance, quality outcomes, and overall business objectives.
Moving forward from understanding how to evaluate and measure Six Sigma solutions, let's now examine how these solutions are tested for feasibility and success in real-world scenarios.

Feasibility and Testing of Six Sigma Solutions

Before fully committing to implementing a solution, it's crucial to thoroughly test it to ensure its practicality and effectiveness.

This is where Failure Mode and Effects Analysis (FMEA) comes into play. FMEA helps in systematically reviewing every aspect of the solution to anticipate and prevent potential failures. It's like examining a detailed map before starting a journey - identifying potential roadblocks and challenges along the way. By doing this, organizations can take proactive measures to mitigate risks and ensure a smoother path towards success.

Consider this as a trial run before a big event. Just like how you wouldn't organize a wedding without testing out the seating arrangement or catering beforehand, piloting or prototyping Six Sigma solutions on a small scale allows organizations to iron out any wrinkles before rolling them out across the entire operation. During this phase, it's essential to gather feedback from those directly involved in the process, as well as stakeholders affected by the problem. This ensures that the proposed solution meets the requirements and expectations of all relevant parties.

Engaging with those who will be affected by the problem or its solution is crucial at this stage. Their insights not only provide valuable input but also help in building support for the proposed changes. It's like getting everyone's opinion before selecting a movie for movie night - it ensures that everyone is invested in the final decision.
For instance, if a new process is being piloted, involving the employees who will carry out the tasks gives them an opportunity to voice their concerns and suggestions based on their practical experience. This valuable input can lead to adjustments that make the solution more workable and acceptable to everyone involved.

After this period of careful trial and examination, we can make informed decisions about which solutions are feasible and effective for full-scale implementation.

Advanced Methods in Six Sigma Problem Solving

In the world of Six Sigma problem-solving, there are advanced methods that take the process to a higher tier. One such technique is Design of Experiments (DOE). This is not about mixing chemicals in a lab, but rather a systematic approach that helps us understand and optimize process parameters. It's like a chess match where you think ahead and carefully plan your moves, except in this case, we're figuring out how to optimize our processes for the best results.

When it comes to experimenting, DOE allows us to compare different factors and see which ones make the most impact on the outcome. Let's say you're baking a cake - DOE helps determine how different ingredients (like flour, sugar, and eggs) or factors affect the final taste and texture of the cake. By using statistical methods, DOE reveals how each factor impacts the result, allowing us to optimize our process for the best outcome. It's not just about guessing or randomly tinkering with variables; DOE gives us a clear and structured method to test and analyze factors systematically. This ensures that our conclusions are based on solid evidence and not just hunches.

For instance, in an automobile manufacturing plant, DOE can be used to find the optimal settings for machines that produce car parts. By adjusting parameters like temperature, pressure, or speed, we can identify the best combination for achieving high-quality products consistently. This kind of precision can save time, money, and resources by pinpointing exactly what needs to be adjusted.

Next up is advanced statistical modeling and simulation methods. These techniques give us the ability to predict potential outcomes of proposed solutions before implementing them in real life.

Just like playing out scenarios in your head before making a big decision in real life brings clarity and foresight; these tools provide a virtual environment for testing different solutions thoroughly. By entering data into sophisticated programs, we can simulate potential changes or solutions within a controlled digital environment. This allows us to see the potential impact and outcomes of these changes without having to commit resources or time to physically testing them.

Let's look at an example; imagine a company looking to reduce their product delivery time. Through advanced statistical modeling and simulation, they can tweak different variables such as production schedules, resource allocation, or transportation routes to see how each adjustment affects delivery times. By running simulations based on historical data and anticipated changes, they can predict how each solution could perform under real conditions. This enables decision-makers to select the most effective solution based on validated data rather than educated guesses.

In conclusion, advanced methods in Six Sigma problem-solving expand our capabilities by providing structured experimentation and predictive analysis tools that help us make informed decisions and optimizations with precision and confidence.
Whether it's optimizing processes in a manufacturing plant or streamlining delivery logistics, these advanced problem-solving tools in Six Sigma pave the way for smarter decision-making and resource management.
