The Journey from Little ‘q’ Quality to Big ‘Q’ Quality
Quality is a fluid concept—difficult to define and
hard to manage, largely because it is subjective. Every individual has their
own perception of quality. Various authors have defined quality differently,
leading to ongoing discussions about its meaning. Juran’s Quality Handbook
provides two essential definitions of quality:
1. Quality
means those features of products that meet customer needs and thereby provide
customer satisfaction.
2. Quality
means freedom from deficiencies—freedom from errors that require rework or
cause field failures, customer claims, and so on.
Dr. Joseph M. Juran states that quality
means fitness for use and emphasizes that it is the customer who defines
fitness. In the 1980s, he introduced the concepts of little 'q'
quality and big 'Q' Quality, which were widely discussed during that
decade.
Juran introduced this distinction to shift
organizations' focus from narrow, product-based quality control to a strategic,
organization-wide approach. His goal was to encourage management leaders to
embrace quality across all levels and functions, not just during
production or service delivery. The evolution from little 'q' quality to big
'Q' Quality marked a significant transformation in how quality was perceived
and managed.
Historical Evolution of Little 'q' and Big 'Q'
Quality Concepts
Juran, known for his Juran Trilogy (Quality
Planning, Quality Control, and Quality Improvement), observed that most
organizations focused too heavily on inspecting product quality—a
practice he referred to as little 'q' quality. He argued for a broader,
more strategic perspective: organizations needed to align quality management
with their strategic goals to achieve sustainable success.
At the time, Japanese industrial products
were outperforming Western counterparts, which compelled Western organizations
to rethink their quality strategies. This transformation extended beyond
inspection and control; it introduced a new vision of quality as an
integral part of the entire business system.
Juran emphasized the role of leadership and system
thinking in achieving quality. He advocated for integrating quality into
the organization’s culture. In his view, focusing solely on little 'q'
quality was insufficient to meet evolving customer needs. Instead, quality
needed to permeate all areas of an organization, from R&D and
finance to customer relations and supply chain management.
In 1987, the International Organization
for Standardization (ISO) introduced the ISO 9000 family of quality
management standards, marking a shift toward systematic quality
management. By the 1990s, the concept of big 'Q' Quality
became aligned with Total Quality Management (TQM) principles,
emphasizing cross-functional collaboration, customer focus, and continuous
improvement.
This evolution also influenced subsequent versions
of ISO 9001, which moved from simple product or service control to a comprehensive
management approach. The newer standards stressed leadership
involvement, error prevention, continual improvement, and customer satisfaction,
thus fully embracing the big 'Q' Quality concept.
Little 'q' Quality
The little 'q' quality concept focuses on operational-level
activities and has a narrow scope. It reflects the traditional
understanding of quality, concentrating primarily on product or service
outcomes.
This approach emphasizes quality control,
inspection, and defect prevention or correction during the production or
service delivery process. Little 'q' quality ensures that each
manufactured part or rendered service meets the required specifications
and expectations.
Big 'Q' Quality
The big 'Q' Quality concept has a broader,
organization-wide focus. It represents a holistic and strategic approach
to managing quality, involving the entire organization and all its
processes.
Big 'Q' Quality focuses on long-term goals,
such as customer satisfaction, continual improvement, and organizational
excellence. This approach incorporates TQM practices, the
implementation of national and international standards, leadership
involvement, and stakeholder engagement. It also requires regular
monitoring and measurement to ensure that quality goals are achieved
consistently.
The ultimate aim of big 'Q' Quality is to
foster a quality culture across all levels of the organization. It
integrates quality into the organization's mission and promotes continuous
improvement practices, such as Kaizen and 5S.
Summary
The concept of big 'Q' Quality encourages
organizations to move beyond individual product or service quality and
develop a comprehensive quality management system. This system requires top
management’s involvement, along with processes and people at all levels,
to ensure sustainable success.
In short, little 'q' quality focuses on "doing
things right," while big 'Q' Quality emphasizes "doing
the right things" for long-term, sustainable success. The
journey of quality has evolved from little 'q' quality to big 'Q' Quality,
reflecting a shift from operational efficiency to strategic excellence.
