What is LEAN MANAGEMENT?

Historically, born in Japan in the automotive industry, more precisely within the Toyota production system in the 1970s, Lean management is a production management method that has the principle of effectively improving the quality and profitability of your company: productivity, cost control, delivery time, development of all employees.

The definition of "Lean" being "lean" or "fat-free" focuses on reducing sources of waste, in order to gain in performance. This is a prerequisite for identifying opportunities to improve production processes in the company. The main objective should not be to focus on reducing financial costs, but to develop an approach from the field as close as possible to the company's employees and collaborators.

Lean is mainly a method used in industry (the automotive industry in particular), but is nevertheless adaptable everywhere regardless of the sector and size of the company.

What are the principles of Lean management in companies?

The principle of this management technique is the search for performance while satisfying the customer.

In companies, the LEAN model aims to eliminate the 3 main enemies of work organization:

  • MUDA

    Waste that does not add value to the product (what ends up in the trash, breakdowns, unnecessary travel, waste of time, things that are added to the product, but that the customer does not want, etc.).

  • MURI

    Excess, overload of work caused by unsuitable processes (personnel, when the workload is not adapted to the number of workers; installations, when the load is greater than what an installation can do (its capacity); stocks, when parts or products do not "turn".

  • MURA

    Variability, or irregularity (machines that do not always take the same time to do the same thing and whose quality varies; operators who do not all and not always do the same work when assigned to the same position; suppliers who do not always deliver the same quantities of raw material).

Lean management particularly tackles seven sources of MUDA in a company: overproduction, delays, waiting, unnecessary stocks, handling and transport activities, superfluous treatments, unnecessary movements (productive or administrative), to which must be added an eighth waste, which is the non-use of the intellectual resources of the staff. To effectively implement Lean Management and therefore, change in the company, there is a range of model tools and methods at your disposal:

If the results are not compliant, it is clear that the process is not compliant and management will invest in identifying and correcting process problems.

Why do Lean Management?

Lean puts the customer and the employee at the heart of the company. It is a real business project aimed at improving performance while improving the working conditions of employees. To achieve change, Lean mobilizes the company's actors in the field, including and especially managers.

This type of management has advantages, but also disadvantages

The Lean management method is mainly based on the continuous improvement of workflows in the company:

  • Reduce waste of all kinds that cost unnecessarily and hinder processes,
  • Manage manufacturing and marketing costs more efficiently,
  • Increase the level of just-in-time by streamlining production flows according to customer expectations,
  • Optimize the communication and training of employees in the company,
  • Motivate employees by consulting them and involving them in changes,
  • Promote the autonomy and responsibility of employees using the agile method,
  • Reassure customers and other interested parties.

Despite the attractive prospects of increasing the company's productivity, we must not forget that Lean Management is thought of in the long term and impacts all the actors of the company.

In addition, it is important not to neglect the health of employees in favor of increasing at the risk that they feel tired, stressed or have a drop in morale. It is essential that everyone can, without constraint, find their place and their role in the long term. In addition, an employee doing useful and impactful work within the company, rather than on worthless busy work, has a better sense of purpose.
