Guide to lean six sigma in project management 2024

Imagine this: your project team consistently delivers flawless work, on time and under budget.

Sounds like a dream, right?

That dream can become a reality with Lean Six Sigma project management.

This powerful approach helps you bridge the gap between where you are and where you want to be, streamlining processes and minimizing errors for peak project performance.

Let’s explore Lean Six Sigma in project management in detail. We will dive deep, from defining its core principles to uncovering its benefits and limitations.

Not just that, we will also demonstrate how Lean Six Sigma methodology can bring improvement in your operations using a project management software like ProofHub.

But before moving ahead, let’s understand Lean Six Sigma first.

What is Lean Six Sigma?

Lean Six Sigma is a powerful methodology that combines two popular approaches to continuous process improvement: Lean and Six Sigma.

What is lean?

Lean project management focuses on eliminating eight types of waste in processes. Waste refers to any activity that consumes resources but doesn’t add value to the final deliverable. This could be anything from unnecessary meetings to redundant approval processes.

Project Management Institute defines Lean as, “To be Lean is to provide what is needed when it is needed, with the minimum amount of materials, equipment, labor, and space.”

It was originally developed by the Toyota Production System (TPS) in the late 1940s. It continued to evolve and refine up till the 1980s. The implementation led to reduced costs, improved performance, and optimal efficiency.

What is Six Sigma?

Six Sigma methodology is driven by minimizing defects and process improvement through a data-driven approach. It emphasizes identifying and eliminating the root causes of errors to achieve near-perfect project execution. Six Sigma uses statistical analysis to pinpoint variations and measure the effectiveness of solutions.

Six Sigma summed up by PMI Institute – “The Six Sigma method focuses on understanding customers’ requirements better and eliminating defects and waste. These objectives are achieved through profound knowledge of statistics, engineering, and project management, as well as the underlying processes and systems.”

Motorola pioneered Sigma principles in 1986, and it continued till it was widely recognized in 1992 by General Electric (GE). It is widely adopted across many organizations and industries to improve quality, save money, and decrease defect rates.

Overall, the combination of the two results in Lean Six Sigma.

Per the definition provided by the American Society for Quality (ASQ),” Lean Six Sigma is a fact-based, data-driven philosophy of improvement that values defect prevention over defect detection.”

Lean acts as the detective, spotting any unnecessary bumps in your project flow. Six Sigma then jumps in as the fixer, using data and clever solutions to smooth out those bumps and get your project back on track.

Lean Six Sigma project management methodology

The Lean Six Sigma methodology complements project management by eliminating unnecessary waste and defects from the processes. This improvement further extends to increasing efficiency, streamlining processes, and achieving some fundamental improvements in operational processes.

The core framework of implementing the Lean Six Sigma methodology is DMAIC. It is a five-phase method—Define, Measure, Analyze, Improve, and Control, and is a problem-solving approach to process improvement.

1. Define

Outline the most value-driven opportunities and possibilities for improvement. Map out all the value-driven elements, focus, scope, issues, and ultimate goals. Determine the performance standard that will highly impact customer satisfaction. Defining these parameters ensures your team shares the same vision.

2. Measure

Draw out project baselines to assess the current performance of your project. This acts as a benchmark measurement against which you can evaluate the effectiveness of implemented improvements. By collecting historical data, customer feedback, and metrics, you can view your goals through a contextual lens.

3. Analyze

Aim to uncover all the possible root causes of the underlying problem. These are the potential factors that contribute to the variation in your process, and end up costing you time, resources, and money. You can visualize these factors by utilizing data visualization tools like Kanban board, Gantt charts, etc.

4. Improve

When all the issues are in front of you, start developing and implementing your functional process improvement plan. You should incorporate team suggestions, brainstorm solutions, and iterate to obtain the optimal solution to eradicate the issue. You can even test your solution to validate the optimal outcomes.

5. Control

Monitor the implemented solutions to ensure sustained improvement of your process. Continually evaluate the improvised processes to look for unusual occurrences and adjust the approach accordingly. Also, to be on the safer side, ensure a response plan is in place to address discrepancies continually.

Lean Six Sigma principles

Lean Six Sigma (as stated above) is a powerful blend of two methodologies. It has five key principles that help organizations achieve operational excellence and predictable project outcomes.

Let’s understand each principle one by one:

1. Customer focus

Companies that prioritize customer experience, witness an 80% increase in their revenue.

And LSS’s principles align perfectly with the trend. That is why its ultimate goal is to deliver value-driven products to customers. This highlights the importance of prioritizing customer needs, satisfaction, and expectations over anything else. That is why, customer feedback is given high priority when refining processes and implementing projects.

2. Data-driven decision-making

Learn Six Sigma doesn’t go vague when it comes to making decisions to improve processes. Instead, you can utilize a statistical analysis of project data insights to improve process effectiveness. By using historical data, current metrics, and various key performance indicators, you can guide process improvement efforts accordingly.

3. Continuous improvement

Continuous improvement is better than delayed perfection. – Mark Twain

LSS is a continual improvement process that promotes sustained improvements. Teams are encouraged to not settle for desired output achievement. But to always strive for better project outcomes. So, multiple evaluations and adjustments are performed to ensure the project’s sustainability over time.

4. Teamwork

The zero-waste ideology of Lean Six Sigma is a team-based strategy. It brings employees from all levels, functions, and departments together to share their diverse perspectives. This results in increased employee engagement levels and enhanced knowledge sharing.

5. Process optimization

The prime goal of LSS is to improve process efficiency and quality by eliminating waste and reducing variations. The improvement strategies are designed to eliminate inefficiencies, ensure smoother operations, and enhance quality production.

When should you use Lean Six Sigma in project management?

No doubt, Lean Six Sigma possesses substantial strengths. But it is not applicable in every scenario

Consider implementing LSS only if you want to

• Eliminate defects and inefficiencies from your processes
• Standardize repetitive projects with well-defined stages
• Increase employee engagement and morale
• Enhance customer experience and satisfaction
• Deliver high-quality results
• Introduce data-driven strategies
• Reduce operational costs caused by rework and delays

Do not consider adopting LSS if

• Your project faces a tight deadline. As LSS is a time-consuming concept.
• You lack access to historical data and cannot stay abreast of current trends.
• You oversee novel or one-time projects with unique requirements and conditions

Advantages of Lean Six Sigma in project management

By optimizing your business processes using LSS, you get:

1. Improved processes

LSS is more of a problem-preventing approach than problem-solving.  It eliminates non-value-added activities, variations, and delays in processes. This results in faster project completion with less time, resources, and wasted materials.

2. Lower expenses

With no waste and defect-free activities to impact your processes, companies can save a significant amount of money in each process cycle. Also, companies can avoid costly inspection-and-rework cycles by embracing a ‘defect prevention’ ideology.

3. Increased profit

By applying a systematic approach to life-cycle assessments, LSS streamlines and accelerates product delivery. Companies can leverage this approach to achieve higher bottom-line results and maximize ROI.

“Companies have saved millions of dollars with this (LSS) approach and anyone can do it.” – Bob Myers, Lean Six Sigma Black Belt, Lecturer in Operations Management at the Georgia Tech Scheller College of Business.

4. Higher productivity

The zero-defects ideology of LSS frees up employees for the core tasks that matter. Also, with minimal bottlenecks in processes, employees can focus more on attaining the organizational vision. This efficiency leads to faster task completion and delivery.

5. Happy customers and employees

Both employees and customers are the two strong pillars of an organization. By delivering high-quality projects and improving operational efficiency, you benefit both categories. Where employees gain positive work experiences through streamlined processes, customers feel satisfied as their needs are met efficiently and effectively.

How can project managers benefit from Lean Six Sigma?

Lean Six Sigma is one of the project management skills that project managers aspire to acquire. But not every project manager is equipped with the same.

However, if you choose to strengthen your command in Lean Six Sigma, you can benefit in several ways:

• It helps you identify the most beneficial aspects that provide the most value to the organization.
• By aligning diverse perspectives and talents toward achieving shared goals, managers can create a collaborative environment.
• Your problem-solving skills advance as you look for effective solutions to eliminate waste and defects.
• It enhances your ability to identify and deal with risks by empowering your strength to tackle unforeseen challenges.

These are just a few examples of Lean Six Sigma wins. You name the industry, and LSS is operational there.

Limitations of Lean Six Sigma in project management

LSS, despite its effectiveness, is not without drawbacks. Here are a few of them:

• Complex in nature

Lean Six Sigma is quite intricate because it requires managers to have prior procedural knowledge of two methodologies – Lean and Six Sigma. Not having the right training and development opportunities in either of the two can lead to frustration and inefficiency.

• No one-size-fits-all solution

If you think every project can be addressed with LSS, then you are wrong. You need to invest a considerable amount of time to analyze and evaluate the processes that may yield profitable results when integrated with LSS.

• Emphasize established procedures

The entire LSS framework focuses on optimizing the existing processes. So, any new projects or processes can not benefit substantially from its implementation.

• Additional resource consumption

While no doubt Lean Six Sigma aims to reduce costs to businesses. But the investment that goes into training and educating your employees in the first place is quite significant. You can not even overlook the factor because the acquired knowledge is substantial enough to operate efficiently.

• No quick results

LSS is a time-intensive process that requires an average of two years to reflect tangible results in the process. This is a huge timeframe for companies that want quick improvements. So, if you are seeking immediate results, do not consider wasting your efforts and talent in LSS.
