When a project falters, it’s often the time for ‘superheroes’ to step in: People who roll up their sleeves and get things done – right in the middle of the troubled project. They turn things around and get the project back on track as quickly as possible. Their approach is rigorous and uncompromising. But the causes of the problems – which vary greatly in nature – are rarely eliminated in the long term. Often, they are the result of many different project participants failing to work together in a coordinated manner. And schedule and cost pressures are also increasing – along with the demand for safety, sustainability and smart technologies. The fact is that building construction and infrastructure projects are becoming increasingly complex. 

So imagine having a management approach that gets everyone in a project or organization working together and that invites them to adapt and constantly improve processes. And imagine a mindset and methodology that is relatively easy to understand, even though it is different from the way we manage today.

Drees & Sommer’s Lean Solutions offer an alternative to the conventional approach to projects and focus on broadening the perspective from a purely resource-oriented view to a ‘flow-oriented’ view – making superhero interventions unnecessary.

Lean Solutions at a glance

Customized Lean Solutions that are right for you

Every company finds itself at a different point on its Lean journey. Many organizations are already familiar with Lean methodologies, so for them it is a matter of understanding and establishing Lean as a culture. Because it is only when people take up their central role and work together in a goal-oriented manner that they can make improvements. At the same time, the construction industry is in a state of transition. The increasing degree of digitization, automation and autonomization is radically changing the nature of construction – and, as a result, the way projects are executed with Lean.

A diverse range of customized solutions is needed that pick an organization up exactly where it is on its path to Lean.

We systematically align processes and the different levels of the organization with project and customer requirements. Whether the project involves real estate, the public sector, production or logistics: Every year, we guide more than 350 Lean projects to success for our customers from a range of sectors. Some Drees & Sommer 150 Lean experts – trained in-house us at our Expert Center – play a key role in achieving these outcomes.
