About Lean

Lean is a management philosophy that allows employees to think about a better design of processes. This philosophy utilizes a collection of methods (toolbox). To turn it into a success, a change in culture is necessary. Because Lean focusses on client value and prevents waste, processes become more efficient and organizations more profitable.

Lean: Common sense

The ideas that resulted in Lean’s existence have been around since the industrial revolution (amongst e.g. Ford). In the nineties, Lean received its name. Toyota owes a massive part of its success of producing passenger cars to its application, and has become a textbook example ever since. Lean is also called the method of common sense. Its emphasis lies on observing the process, and less on its foundation.

Lean and iPM-Method

Preferably, iPM starts by aiming the organization together with the management team. We establish strategic goals and appoint client chains. After this, an analysis of difficulties and chances in said chain is made. A conclusion of this analysis can be: structurally change the way things are operated. Often, it is not necessary to start a program or project to achieve this, but in certain complex cases, it can be useful. For these cases, we use Lean. This management philosophy is a good addition to the iPM-Method, because its starting point is employee involvement as well.

Lean/Six Sigma rather not separated from iPM

Organizations that start working with Lean, approach it as a sum of projects for process improvements. They do not always succeed in linking it to daily management, let alone strategy. Clients often request to revive a Lean-project. We do not, however, recommend Lean without iPM, because it is not sufficiently linked to strategy and client chains. It can take a while for Lean to yield positive results on its own, which can discourage employees. And if Lean finally bears fruit, the tendency to think it is ‘finished’ arises. Whereas the idea behind iPM is to keep adjusting every day.


iPM does not consider Lean as an aim on its own. We use our years of experience in applying it to make sure Lean lives and embeds itself in the organization. The attitude of your employees is very important. We emphasize culture change. Organizations are looking for improving performances, day after day.
