Consultant

Trool Consulting

As a consultant for Trool my primary job description was to go into different west Michigan automotive businesses that supplied the "Big 3" as an experienced professional in the metal stamping business and find the inefficiencies in the daily production flow of their business. I would usually spend a week at a particular company going through the various processes, evaluating cycle times on presses, change over times, lack of proficient execution and inefficient movement (wasted steps). At the end of the week I would give a power point presentation to a group of management at the given facilities demonstrating the areas of prominent gains through quantitative data and short video clips taken while their staff performed various tasks related to their own admitted faults and areas where improvements needed to be made.I would summarize by giving detailed examples of jobs/ change overs that had run while I was present and show the areas that could most be improved upon, or on certain jobs how properly programming a transfer system to utilize corner round could gain them 5 strokes per minutes while decreasing the strain on a transfer system. I averaged a 35-50% increase in productivity when the Company who acquired our services implemented the plan laid out before them. Through experience and a foundation of Metal Stamping professionals it was a valued way to increase my knowledge, pursue continued growth, while subsidizing my income while I went to college.
