4. Total quality management (TQM)

Total quality management (TQM) is the process of applying a zero defect philosophy to the management of all resources and relationships within an organization as a means of developing and sustaining a culture of continuous improvement which focuses on meeting customer expectations.

Remark: TQM的三个关键词

1 Total = 全员

2 Quality = 目的是使客户满意

3 Management = 主动管理,而非事后控制

Three basic principles of TQM

(1) Get it right, first time.

One of the basic principles of TQM is that the cost of preventing mistakes is less than the cost of correcting them once they occur. Every mistake, delay and misunderstanding directly costs money through wasted time and effort, including time taken in pacifying customer. The lost potential for future sales because of poor customer service must also be taken into account.

(2) Continuous improvement

TQM is dissatisfaction with the status: the belief that it is always possible to improve and so the aim should be to ‘get it more right next time.’

(3) Customer focus

Quality is examined from a customer perspective and the system is aimed at meeting customer needs and expectations.

Cost of quality is the ‘Difference between the actual cost of producing, selling and supporting, products or services and the equivalent costs if there were no failures during production or usage.’

Cost of quality can be analysed into:



Prevention costs - costs incurred prior to or during production in order to prevent defective products or services from being produced.

例如: quality engineering; design or inspection equipment; maintenance; training; acquiring higher quality material

Appraisal costs - are the costs incurred to ensure that materials and products meet quality standards.

例如:acceptance testing; inspecting purchased parts,work in progress and finished goods; performance testing

Internal failure costs - are costs arising within the organisation of failure to achieve the quality specified.

例如:failure analysis; rework and reinspection cost; loss from lower selling price for sub-quality goods; cost of scrap.

External failure costs - are costs incurred when the products or services fail to conform to requirements or satisfy customers’ needs after they have been delivered.

例如:costs of handling customer complaints; warranty replacement; repair of returned product etc. Costs within this category can have a dramatic impact on future sales.

哈喽!努力学习的小天使:

质检是检查计划的执行情况,检查是否符合计划的预期结果。是贯穿生产和服务整个过程的一项管理活动。并非生产或服务过程的最后一步。

质检出问题才能促使提出更好的解决办法进行以后的生产和服务,如采取优化流程,引进设备等手段。

每个努力学习的小天使都会有收获的,加油!
