Journey for Quality

 

Quality thinking developed with manufacturing systems, and could be considered both order qualifier and order winner. APICS Operations Management Body of Knowledge Framework defines order qualifiers as “screening criteria that must be fulfilled before a firm’s products or services can even be considered as possible candidates for purchase”, and order winners as “unique characteristics or combinations of characteristics that result in a competitive advantage and obtaining (winning) an order from the customer.” Both terms originated from Oxford professor Terry Hill. Palgrave Macmillan has updated and re-issued his old books on Operations Management.

An abridged history of Quality

Going back to our main topic, quality hasn’t always been considered as order qualifier or order winner. During times dominated by philosophy of mass manufacturing, quality was defined from technical aspect, rarely considering the opinion of the end customer and little was done to improve the quality of the system. In such environment quality came at a high price. Works of William Edwards Deming, Philip Bayard Crosby, Joseph Moses Juran and Kaoru Ishikawa shaped modern quality movement.

Table 1 provides a timeline of how quality thinking developed throughout the history as described by Graeme (2011). It should be noted that in this case time period does not represent the first appearance of the theory or approach, instead it represents which theories and approaches were dominant in respective era.

Table 1: Development of quality thinking

Era Title Description
Pre-1900s Craftsmanship era Skilled workers, peer-assessment
1900s–1950s Standardisation, Mass Production, Quality Control Industrialisation, scientific management, unskilled labour, 100% inspection
1930s–1950s Quality Assurance era Statistical Process Control, supplier assessment
1950s-1970s Total Quality Management era Deming, Leadership, Systems Thinking, Customer Focus
1970s–1990s Standards and Awards ISO 9000, Baldrige Award, European Foundation for Quality Management Excellence Award
1990s–present Initiative era Lean, Six Sigma, Business Process Re-Engineering

 

Progressive conceptual development is presented in Table 2, based on the phases identified in works by James (1996), Dale et al. (2007), Kaye and Dyason (1995), and Devadasan et al. (2003).

Defining Quality

Before moving to Quality Management, let’s consider the following definitions of quality:

The totality of features and characteristics that bear on the ability of a product or service to satisfy a given need. – BS 4778-2:1991
Fitness for purpose. – Juran and Godfrey (1999
Conformance to requirements. – Crosby (1980
Satisfaction of the customer. – Ishikawa (1985)
The total composite product and service characteristics of marketing, engineering, manufacture, and maintenance through which the product and service will meet the expectations of the customer. –  Feigenbaum (1961
Quality conformance means consistently delivering services and products in line with their design specifications, which, in turn, need to reflect customer needs. – Hill and Hill (2011
Quality is a dynamic state associated with products, services, people, processes, and environments that meets or exceeds expectations and helps produce superior value. – Goetsch and Davis (2014)

According to Arnold et al. (2012), the following definition of the quality contains the most commonly accepted ideas in business:

Quality means user satisfaction: that goods or services satisfy the needs and expectations of the user. – Arnold et al. (2012

From the presented definitions we can delayer quality into several core ideas:

  • customers define quality,
  • quality should add value to the product or service,
  • the product or service should meet or exceed the expectations of customer,
  • customer may have unspoken expectations, and
  • quality is an organizational effort.

Increased emphasis on quality soon revealed how inadequate traditional systems were for handling quality related issues. Quality Management  was devised as an approach to ensure quality of products and services. Differences between the traditional approach to the quality and managing for quality is presented in Table 3.

Table 3: Traditional approach to quality versus managing for quality

Traditional approach to the quality Quality Management
Emphasis on management Emphasis on leadership
Short term focus Long term focus
Conformance to internal standards, lack of customer focus Conformance to customers standards, aims at exceeding the expectations of the customer
Quality is achieved at high cost Cost of quality is assessed
Mechanistic organisation, functional departments, barriers between departments Focus on system thinking
Managers think, workers do Empowering the workers

 

Managing for Quality

Since quality is a complex concept, it should be addressed by joint effort of all departments within the company. Dr. Joseph Juran was a big proponent of actively managing for quality, instead of trying to inspect it into the product. One of his notable contributions to Quality Management field was his Quality Trilogy (Figure 1). Inspired by financial processes of (1) budgeting, (2) cost control, expense control, and (3) cost reduction, profit improvement, he created (1) quality planning, (2) quality control, and (3) quality improvement. In other words, modern Quality Management consists of:

  1. Quality Planning
  2. Quality Assurance
  3. Quality Control
  4. Quality Improvement

Core principles of Quality Management are (Graeme, 2011Goetsch and Davis, 2014):

  • Customer focus
  • Strategic focus
  • Leadership focus
  • Process focus
  • People focus
  • Scientific focus
  • Continuous improvement
  • Systems thinking

Some of the tangible and intangible benefits of Quality Management are:

Concluding Remarks

This is the first post in my “Quality Management” series, and as such it was appropriate to start with concise historical overview, from quality inspection to strategic quality management. After that we took a look at various definitions of quality and used them to delayer quality into several core ideas. Finally, I concisely described core elements of Quality Management, as well as its benefits.

In following posts I will write more about William Edwards Deming, Philip Bayard Crosby, Joseph Moses Juran and Kaoru Ishikawa, and their contributions to the Quality Management field. After presenting aforementioned quality philosophers I will write more about various Quality Management Systems and Quality Management Frameworks. I will wrap up my Quality Management series with a post on Continuous Improvement.
