What is Enterprise Excellence, Operational Excellence, Lean, Six Sigma and Lean Six Sigma?

Grianan Consulting delivers Enterprise Excellence, Operational Excellence, Lean, Six Sigma, and Lean-Six Sigma services.

All these methodologies are used to improve processes, enhance quality, and achieve better overall performance.

For simplicity, Grianan Consulting typically uses the umbrella term ‘Enterprise Excellence’ when describing our services, however, for clarity, some specific differences are detailed below:

Title	Focus	Scope	Goal
Enterprise Excellence	Enterprise Excellence extends beyond operational aspects and includes strategic, cultural, and leadership elements in addition to operational improvement.	It encompasses Operational Excellence and other methodologies but also integrates strategic planning, leadership development, and other organisational aspects.	The goal is to align an organisation's strategy, culture, and operations to achieve exceptional results in terms of efficiency, customer satisfaction, employee engagement, and long-term sustainability.
Operational Excellence	Operational Excellence is a business philosophy that emphasises continuous improvement in all aspects of an organisation's operations, with a focus on efficiency, customer satisfaction, and cost reduction.	It is a broad approach that encompasses various methodologies and tools, including Lean and Six Sigma, but it is not limited to any specific methodology.	The primary goal is to create a culture of continuous improvement, where all employees are engaged in identifying and eliminating inefficiencies to enhance overall organisational performance.
Lean Six Sigma	Lean Six Sigma combines the principles of Lean and Six Sigma to address both efficiency and quality issues in processes. It aims to eliminate waste while reducing defects and variations.	Lean Six Sigma integrates Lean's waste reduction techniques with Six Sigma's data-driven problem-solving approach to achieve a comprehensive process improvement.	The primary goal of Lean Six Sigma is to create efficient, streamlined processes with high-quality outputs, all while reducing costs and enhancing customer satisfaction.
Six Sigma	Six Sigma is a data-driven methodology that focuses on reducing defects and variations in processes to achieve higher quality and consistency.	Six Sigma uses a structured problem-solving approach (DMAIC - Define, Measure, Analyse, Improve, Control) to improve processes, and it's often applied to address specific quality-related issues.	The main goal of Six Sigma is to reduce defects, minimise process variations, and improve overall quality.
Lean	Lean, or Lean Thinking, is a methodology that concentrates on the elimination of waste (non-value-added activities) from processes to improve efficiency.	Lean principles primarily target process optimisation, reducing lead times, and increasing efficiency.	The primary goal of Lean is to streamline operations and improve productivity while maintaining or enhancing product or service quality.
