5.3 Lean production & quality management (HL)
Unit 5.3 - Lean production and quality management (HL only)
Learning outcomes
This section of the IB Business Management syllabus examines two vital aspects of operations management for HL students: lean production and quality management.
Lean production is a philosophy or organizational culture about streamlining production processes in order to increase efficiency and reduce waste. Quality means that a product is fit for purpose, i.e. the good or service meets or exceeds the needs of its customers. It is about achieving customer satisfaction. Approaches to quality management include quality control (QC) and quality assurance (QA).
Consider the case study below and discuss the likely impact such product recalls are likely to have on the company in question.
Case Study - Apple recalls Beats speakers due to fire risk
In June 2015, Apple called for its customers of its Beats loud speaker system to stop using the device and to return these for inspection due to potential fire risks. The speakers sell for around $380 but the batteries were prone to overheating. Reports included a burn to a consumer's finger and damage to another consumer’s desk. The product recall included over 230,000 units of Beats speakers sold in the USA.
The US Consumer Product Safety Commission reported that "Apple has received eight reports of incidents of the speakers overheating, including one with a burn to a consumer's finger and one with damage to a consumer's desk."
Apple offered to fully reimburse customers upon proof of purchase. The company bought Beats Electronics for $3 billion a year earlier in 2014.
