Kaizen, JIT and Quality Management
This complete preview comes from the Lean Production and Quality Management unit. It introduces the core language, shows the method in context, and gives you a real example of the lesson quality before you create an account.
Lean Production
Lean production is a philosophy, not a single technique — it is about eliminating waste in all its forms, from excess inventory to unnecessary motion to defects that require rework. After this lesson, you will be able to contrast JIT and JIC inventory management (including JIT's critical supply-chain vulnerability), explain how Kaizen differs from one-off large-scale changes, and distinguish quality control from quality assurance and TQM.
Kaizen (Continuous Improvement)
A philosophy of making small, ongoing improvements throughout the business, often driven by frontline staff suggestions — rather than occasional large-scale overhauls.
Just-in-Time (JIT) vs Just-in-Case (JIC)
JIT — materials/stock arrive exactly when needed in production, minimising stock-holding costs but increasing reliance on a dependable supply chain. JIC — holding buffer stock as a safety margin against disruption, at the cost of higher inventory-holding costs.
Quality Management
Quality management sits at the intersection of operations and marketing — the quality a business delivers directly shapes customer satisfaction, brand reputation, and the cost of rework and returns. After this lesson, you will be able to explain how quality circles harness frontline knowledge for continuous improvement, and how benchmarking against best-practice competitors identifies performance gaps that internal analysis alone might miss.
Quality Control, Assurance and TQM
Quality control inspects outputs after production. Quality assurance builds quality checks into the process itself, to prevent defects occurring. Total Quality Management (TQM) is a company-wide philosophy making quality everyone's responsibility, not just one department's — often paired with quality circles (small staff groups meeting to identify and solve quality problems) and benchmarking (comparing performance against best-practice competitors).
Common ErrorDon't treat JIT as risk-free — it minimises stock-holding costs, but a supply chain disruption can halt production almost immediately, since there's no buffer stock to absorb the shock.
Scenario
A car manufacturer using JIT experiences a major production stoppage when a key supplier's factory floods, since it holds no buffer stock — illustrating the trade-off between JIT's cost savings and its vulnerability to supply chain disruption.
Practice QuestionExplain one advantage and one risk of a business adopting just-in-time (JIT) inventory management.
