CONTEXT

One of the world leading manufacturer of elevators. 

Re-use approach was inefficient, and design rework for each new product generated avoidable costs and development time.

Every high-rise project required a high level of customization, due to :

  • Regions
  • Building (customer) specificities

No global modular approach to address these customization challenges while developing common components.

OUR APPROACH

The customer context led CESAMES to the development of a Product Line approach based on independent modules.

Here are the 4 main phases that we followed:

1.

Definition of Standard Interfaces, and decoupling strategies for all components (interfaces fixed, and defined for several sets of constraints),

2.

Development of a modular architecture, based on a a few platforms, independent modules, enabling the development of new products by combination of modules

Standard and capacitive Interfaces

Modular architecture definition, highlighting standard and customized components

3.

Product Philosophy : “Standardize what’s hidden, Customize what’s visible”,

4.

Setting up of an Out-ot-cycle governance, managing portfolios, defining and developing out-of-cycle processes. 

CREATED VALUE

  • Modularization of the whole architecture : 3 platforms, ~100 modules and ~1000 modules variants.
  • This new approach has led to savings :
  • Recurring cost reductions between 15 and 30%, depending on the different platforms,
  • Time to market reduction, between 10 and 40% (all platforms),
  • Reduced development effort between 5 and 40% (all platforms).
