The kaizen approach is a lean production method - employees should be improving their work slightly all the time, instead of just making one-off improvements
This reduces waste as employees are constantly evaluating the way they work and finding ways to be more efficient
To have a culture of continuous improvement in a business, employees need to know how to suggest improvements - there needs to be appointed people who will listen to workers and help to implement any ideas they have
Employees need to be encouraged to question why a problem has occurred and even employees at the bottom of the hierarchy have to be given some control over decision-making
Kaizen helps workers feel involved in quality assurance. It's also cheap for the business to introduce
The downside of kaizen is that, because it makes small changes over time, it's not great for urgently improving quality. It needs the business to be willing to commit to the method in the long term
