Lean Principles at KAEFER

Getting things right the first time.

Imagine yourself on a construction site. A worker is idly waiting for materials to be delivered. But they haven't turned up yet. Many times in these cases, people will be afraid to say ‘boss, I have a prob­lem’ because they don't want to be seen as not working. That wastes time. That’s not lean.

Lean is ensuring that it's ok to talk to the boss and identify issues. As well as solutions and suggestions for improvement. And Lean Site Management guarantees that the right materials are at the right place at the right time, in the right amount and right quality.

It is not about reinventing the wheel, but rather about optimising a proven concept and ensuring that the wheel runs smoothly without any interruptions. Which means employing simple measures such as planning and performance management – thinking about what to do before, during and after a shift and how to achieve agreed goals.

We call getting things right the first time heading towards ‘True North’. That involves creating stable work­flows, working with optimal crew sizes, comparing actual and expected performance as well as root cause analysis to further improve the process.

The new PPM-Board gave me a better night’s sleep – I do not have to worry as much about tomorrow's problem.

To apply the four principles of lean - flow, takt, pull and zero defects - we employ the following seven points:


Chal­lenge con­ven­tional be­liefs – without chal­lenge there can be no pro­gress.


Ex­per­i­ment – try it or you’ll never know.


Tol­er­ate fail­ure – im­prove­ment re­quires pa­tience.


Trust – im­prove­ment can­not res­ult in loss of jobs.


Work as a team – total op­tim­isa­tion rather than local (in­di­vidual) op­tim­isa­tion.


Be flex­ible – ri­gid struc­tures/​policies will limit pro­gress.


Be dis­cip­lined – stick to the stand­ards.
