When a business is firmly established, a common method used to optimise the business is to apply various techniques used in the Six Sigma methodology which is a scientific way of improving processes.
Six Sigma is about understanding the effectiveness and yield of a business process, by measuring issues and defects.
Then, using a set of tools, techniques and methods, you can resolve issues, eliminate waste, reduce defects, optimise profits and improve customer experience.
| Six Sigma (6σ, Lean Six Sigma)|
A set of management techniques intended to improve business processes by greatly reducing the probability that an error or defect will occur.
Six Sigma is best suited to manufacturing and retailing industries where ‘real defects’ can occur during product manufacturing, but has more recently been applied to professional industries and corporations also who are looking to reduce waste, effort and defects for processes and procedures relating to customer experience – it’s all about Quality Management.
Six Sigma is all about quality control and continuous improvement, improving profitability and productivity to reduce, eliminate and resolve defects and waste in products or services.
Six Sigma is often compared against Human Centred Design which rather applies a customer-centric approach to problem solving and focuses on the experience, rather than profitability and productivity.
Six Sigma is all about achieving the highest-standard in quality which is a maximum tolerable 3.4 defects per one million products or service processes.
A ‘defect’ according to Six Sigma is anything that from a customer’s perspective is not acceptable and means the customer will need to contact the organisation again to either fix the issue, arrange a refund or arrange a repair.
