DFSS concept

Design for Six Sigma (DFSS) is an engineering design process, business process management method related to traditional Six Sigma. It is used in many industries, like finance and marketing. It is based on the use of statistical tools like linear regression and enables empirical research similar to that performed in other fields, such as social science. Rather than the traditional Six Sigma method of improving an existing product or process to reduce defects, DFSS utilizes the five stages of Define, Measure, Analyze, Design, Verify (also known as DMADV) to determine the needs of customers and then design a solution to meet those needs. Quality Function Deployment (QFD) is a focused methodology for carefully listening to the voice of the customer and then effectively responding to those needs and expectations. Design for Six Sigma and the House of Quality QFD helps transform customer needs into engineering characteristics for a product or service, prioritizing each product or service characteristic while simultaneously setting development targets for a product or service.

Staff Union (SIASU), Singapore Government and other regulatory authority at destination country. Alpa-S is SIA’s pilot union, as pilot are normally highly trained and difficult to replace, they have a much power over the airlines and will severely affect the business if they were to go on strike. SIA often had to invite government involvement to mediate major dispute unresolved [Yun, 24th Apr 2009]. As compare with Alpa-S, SIASU had a lesser bargaining power as other staff and crew have less expertise comparing with Alpa-S and are very diversify in its members background and job scope.

This directly impact on the route SIA able to offer and competition it will face [Calingo. P141. 1997]. As major share holder of SIA through Temasek Holding, Singapore government have the power to intervene policy and business process it needs to.

Other regulatory authority may also affect the business process of SIA, for example, recent allegation by Australian Competition and Consumer Commission (ACCC) that Singapore airline cargo enter into a price fixing cartel [ACCC, 22nd Dec 2008]. As these foreign regulatory body have limited restriction on SIA and difficult to affect SIA’s business process, the power is consider low.
