A major problem in seafood companies is the increased reliance on automated or semi-automated plant for packing areas. Continuing new product development means that these lines are regularly faced with new types of packaging or packing steps. This particular project was an investigation, using the Six Sigma approach, of the causal factors of breakdowns of a particular labeling machine. A team comprised of students on the MSc in Productivity & Innovation, together with staff from the Grimsby Institute, was assembled to work on problem identification and root cause analysis. A series of treatments was identified and a 'design of experiments' approach was used to study the effects of changing a range of parameters, the possible benefits of these solutions and to derive confidence in the final solution. Modifications were made to the labeling machine and these have resulted in a reduction of 2% reject rate and Six Sigma has been seen as a useful approach to effectively manage the change process.
