Standardiserat arbetssätt för kunskapsprocesser
? En fallstudie på en prototypverkstad
In recent years, Lean has been implemented in a variety of companies with focus areas that differ from the conditions that characterizes manufacturing. This transfer has contributed to fairly superficial results because companies almost exclusively focus on Toyotas methodology and not on the goal of Lean. The effort of transforming Lean from manufacturing to any organization requires a definition on a general level and a view of Lean as a system. One of the core principles of Lean and the foundation of continuous improvements is standardized work. In product development there is a negative view on standardized work, where the engineers state that the principle is not applicable for knowledge processes that include non-repetitive and creative work.In the framework of this master thesis literature has been studied to find support that standardized work is applicable for product development and areas that include knowledge processes. Standardized work within product development and manufacturing at Toyota will be presented in this master thesis to emphasize that this principle supports the philosophy even if the application is made on different levels. Standardized work at Toyota is not based on similar work; it is rather saturated by Lean philosophy and associated values and principles.This thesis aims to identify problems and its root causes at the prototype workshop UTPW, at Scania, and conclude what measures that can be established for improvement. The thesis is based on methodology with close relations to action research because the workshop is continuously improving. The results obtained during the work have therefore been presented during three occasions to contribute to these improvements. The methodology used for achieving the purpose of this thesis is based on both scientific theory and Lean theory.The manufacturing process at mechanical workshop works great, but is characterized in some aspects of abnormalities, long deliveries and complex information- and product flows. The majority of the identified abnormalities in the mechanical processing are based on a flawed communication between customer and workshop. The additive manufacturing has a high workload and has therefore difficulties to keep up with the work. The additive manufacturing is working standardized but needs to eliminate waste in the process and further investigated the takt time in order to reduce the workload. The mechanical processing must primarily stabilize manufacturing through standardization at a high level to eliminate the identified abnormalities and problem areas.
