Initial situation

Medium-sized elevator manufacturers, such as Lutz Aufzüge, can successfully compete in the market by offering customized solutions tailored to individual customer requirements. However, the high degree of customer individuality means that many elevators have to be developed as one-offs and manufactured individually. Without appropriate measures, this inevitably leads to greater complexity within the company and ultimately to higher costs. 

Objective

• Lutz Aufzüge 
• Reduction of development and production costs while simultaneously providing customized new systems
• Modular kit strategy
• PKT
• Improvement of method integration for continuous and independent variance control in SMEs
• Further development of the integrated PKT approach
• Inclusion of boundary conditions for computer support of the approach

Procedure

In an initial analysis of internal and external variance, the product range was restructured and the scope of services for the new modular system was developed jointly by management, sales, and design. The new module boundaries were defined in the project using the methodological building blocks of "variant-oriented product design" and "life cycle modularization." The modular structure of the new system was adapted to the requirements of all life phases of the company.
