Overview

As a manufacturing business, one of the main areas of focus is utilization of the production floor. In the case examined here, the factory works 247 and every production stop reduces the total units that can be produced and therefore undermines revenue and profitability. Understanding trends, main root causes and other insights from analyzing this data will enable the organization to focus on the most crucial improvements that need to be made.

Goals

Maximize production utilization in order to achieve higher profitability.

Objectives

  • Analyze the utilization rate for every period of time, error type and product type to figure out what should receive higher focus.
  • Understand total downtime in order to have a numeric reference that can be used to analyze trends and problematic areas.
