Shift Change Optimization

Shift Change Optimization

A simple way to improve your company's efficiency is to do the following: choose a process that is repeated every day or even several times a day, and optimize it to reduce waste in terms of time that is not value-added to the business and inefficient production starts.

Background and objectives

Customer details:

  • Company dedicated to the manufacture of household chemical products
  • Performance on a semi-automatic high-production line
  • Analysis of the shift change process

Starting point:

  • 40 minutes of end-of-shift cleaning
  • 15-minute startup
  • A total of 55 minutes per shift

Aim:

  • Reduction of time to 30 minutes, without increasing the number of people
  • A gain of 50 minutes of daily production, equivalent to an efficiency increase of 5% per shift

Calendar

Scope of work:

  • Analysis – Design: plant observations
  • Brownpaper & brainstorming workshop
  • Design of standards and procedures
  • Implementation and adjustments: on-site observations
  • Implementation control: monitoring results

Requirements and suggestions for improvement:

  • 3 people trained to meet the defined standard
  • Task allocation and operator balancing
  • Outsourcing tasks with the machine running
  • Definition of cleaning frequencies during the shift
  • Recovery of units during the shift
  • 5S solutions adapted to the shift change process
  • Proposal for improving existing tools and utensils
  • Control and monitoring of times
