Business: AQA A Level (2023 Specification), topic 4.3.2
Lean Production
Lean production focuses on cutting out waste and maximising efficiency across business operations. It is designed to do more with less by using fewer resources while maintaining high quality.
Definition and principles
- Lean production is an approach to management that focuses on cutting out waste whilst ensuring quality.
- It relies on continuous improvement where employees constantly seek small, positive changes.
- It focuses on activities or products customers will pay for, making them on time and with high quality.
Types of waste in operations
- Overproduction: Making products before they are actually demanded by customers.
- Inventory and waiting time: Goods sitting on a factory floor without use or employees waiting for the next step in a process.
- Transport and general motion: Moving materials or products unnecessarily around a facility or between locations.
- Defects: Poor quality requiring rework or customer returns.
- Underutilised people: Staff capabilities not used or demotivated employees.
Real-world examples
- Toyota: Pioneered lean manufacturing by empowering assembly-line workers to halt production if they spotted a defect, preventing mass errors.
- Greggs (Bakery): Optimises bakeries with standardised recipes, efficient layouts, and demand-based baking to eliminate movement waste and overproduction, maintaining low costs.
- NHS (Healthcare): Applies lean principles to eliminate waiting times and unnecessary processes in the patient journey, streamlining referrals and reducing operational costs.
Benefits of lean production
- Lower costs: Eliminating waste directly reduces storage, material, and labour expenses.
- Improved quality: Focusing on doing things right the first time significantly reduces customer returns.
- Better speed and flexibility: Lean operations can adapt rapidly to changes in consumer demand.
- Services and offices: It applies to different services, such as healthcare, call centres or offices.
