Six sigma in project management - a quick guide 

What is Six Sigma?

Six Sigma isn't just a fancy term, it's a method for businesses to significantly improve their processes. By focusing on reducing defects and variations, Six Sigma helps achieve near-perfect quality. Imagine a process with only 3.4 mistakes per million opportunities!

This is achieved through a structured approach called DMAIC. It stands for Define, Measure, Analyse, Improve, and Control. Each step helps identify and eliminate the root causes of inconsistencies in a process, ultimately leading to improvements.

The term "Six Sigma" itself has a statistical origin. "Sigma" (σ) is a symbol used to measure how much a process deviates from its ideal state. In a perfect world (represented by a bell curve), six sigmas (three above and three below the average) signifies an extremely low defect rate.

What is Lean Six Sigma?

Think of Lean Six Sigma as a powerful one-two punch for improving your business processes. It combines the strengths of two methodologies - Lean and Six Sigma.

• Lean focuses on eliminating waste. It identifies activities that don't add value and trims them away. This streamlines processes, reduces defects, and improves quality, all while using fewer resources. Basically, it's about doing more with less.
• Six Sigma, on the other hand, is a data-driven approach that minimises variations and defects. It uses a structured method (DMAIC) to define, measure, analyse, improve, and control processes, ensuring consistent and predictable results.

By combining these two techniques, Lean Six Sigma offers a comprehensive approach to process improvement. It can be applied across various industries, from manufacturing to healthcare, to boost efficiency, cut costs, and ultimately, make your customers happy.

The 5 pillars of Six Sigma

Six Sigma isn't just about tools and techniques, it's built on a strong foundation of principles. These five core principles guide the entire process:

1. Customer focus

Everything starts with the customer. Six Sigma emphasises understanding customer needs and expectations. This becomes the benchmark for defining quality in your processes.

2. Data-driven decisions

Forget hunches and guesswork. Six Sigma relies on data to identify problems and measure improvements. By mapping the value stream, you pinpoint areas of waste and inefficiency. Data then helps you target the specific problem areas for transformation.

3. Eliminate waste

Not all process steps are created equal. Six Sigma identifies and removes activities that don't add value for the customer. This streamlining reduces defects and improves overall efficiency.

4. Teamwork makes the dream work

Six Sigma isn't a one-man show. It requires collaboration across all levels. By involving stakeholders and leveraging their diverse expertise, you create a strong team environment for problem-solving.

5. Embrace change

Six Sigma is about continuous improvement. When inefficient processes are removed, it can necessitate changes in work practices and employee mindsets. This principle encourages a culture of flexibility and adaptability to ensure long-term success.

Six Sigma's tool belt - DMAIC and DMADV

Six Sigma offers two main methodologies to tackle process improvement - DMAIC and DMADV. Both involve a series of steps but cater to different scenarios.

DMAIC - The doctor for existing processes

Imagine DMAIC as a doctor for your existing processes. It's a data-driven, five-step approach used to diagnose and improve current products or services, ultimately leading to better customer satisfaction. Let's break down the steps:

• Define - Clearly identify the problem or opportunity for improvement.
• Measure - Gather data to understand the current state of the process.
• Analyse - Use the data to pinpoint the root causes of variations and defects.
• Improve - Implement changes to address the root causes and enhance the process.
• Control - Monitor the process to ensure the improvements are sustained.

DMADV - Designing for success from scratch

If you're building something entirely new, DMADV is your guide. This five-step methodology is part of Design for Six Sigma (DFSS) and focuses on creating processes that are efficient and minimise defects right from the start. Here's how it works:

• Define - Clearly define the project goals and customer needs.
• Measure - Identify the critical factors that affect the success of the design.
• Analyse - Develop and evaluate different design options.
• Design - Select the best design option and create a detailed plan.
• Validate - Test and refine the design to ensure it meets all requirements.

By understanding the strengths of DMAIC and DMADV, you can choose the right approach to optimise your business processes, whether you're revamping existing ones or building entirely new systems.

The DMAIC roadmap of business transformation

While Six Sigma offers various tools, DMAIC is the core methodology used by practitioners. It's a data-driven, five-step approach that guides business transformation. Here's a breakdown of each phase:

• Define - This customer-centric phase sets the stage. You clearly define the problem or opportunity for improvement, ensuring it aligns with customer needs.
• Measure - Here, data takes centre stage. You identify the key metrics relevant to the project and choose the right tools to measure them. This data paints a clear picture of the current process performance.
• Analyse - Time to delve into the "why" behind the problem. This phase involves analysing the process to identify the root causes of variations and defects.
• Improve - Armed with insights from the analysis, you develop and implement solutions to address the root causes. This phase focuses on how to improve the process implementation for better results.
• Control - Sustainability is key. The final phase ensures the implemented improvements are effective and long-lasting. You monitor the process to confirm it meets the performance objectives and adjust if needed.

By following the DMAIC roadmap, Six Sigma empowers businesses to continuously improve their processes, leading to increased efficiency, reduced costs, and ultimately, a higher level of customer satisfaction.

Is Six Sigma a perfect fit for your project?

Six Sigma can be a powerful tool, but it's not a one-size-fits-all solution. Before diving in, consider these factors to see if it aligns with your project needs:

• Strengths and limitations - Six Sigma excels at incrementally improving existing processes in large-scale manufacturing or service delivery. It might not be the best choice for projects seeking radical innovation or those with limited resources.
• Project management - Six Sigma focuses on process improvement, not necessarily project management itself. Consider combining it with a dedicated project management methodology for optimal results.

Training and investment - Implementing Six Sigma company-wide requires extensive training for all team members. This investment in time and resources needs to be weighed against the expected benefits.

Here's how to decide:

• Evaluate different methodologies - Compare Six Sigma to other approaches. Consider factors like project type, budget, and desired outcomes.
• Focus on existing processes - If your project aims to refine established processes for efficiency and quality gains, Six Sigma can be a great fit.

Remember - Six Sigma is a powerful tool, but it's most effective when implemented strategically.
