Method & Evidence

AimTo assess the effectiveness of implementing Lean Manufacturing (One-Piece-Flow) elements in a shock absorber production company.
MethodMixed-methods: Value Stream Mapping (VSM), 5 Whys root cause analysis, and simulation, followed by implementation and verification.
ProcedureThe production process was analyzed using VSM to identify key issues. The 5 Whys tool was employed to determine the root causes of these problems. A simulation was used to model the introduction of a One-Piece-Flow system, and the most optimal solution was then implemented and its results verified.

Strengths & Limitations

Strengths

  • +Practical application of theoretical Lean concepts.
  • +Quantifiable results demonstrating significant improvements.

Limitations

Real-world production environments can be complex, and resistance to change from stakeholders may impact implementation success.

Reliability & validity

The study's validity is supported by the use of established analytical tools (VSM, 5 Whys) and the verification of implemented changes. Reliability could be enhanced by longer-term monitoring of the implemented system.

Think critically

To what extent can the success of this Lean implementation be attributed to the specific product (shock absorbers) versus the methodology itself?
