Explaining 5S Lab Management

The Stress Physiology Research Group is working according to international standards, complementing each other at all levels.

5S Explained:

The 5S methodology has found its origin in Japan. Aim is to deliver high quality results, in the most efficient way, within the shortest time frame, at the lowest cost while maintaining full quality control and client satisfaction.

The system of 5S is a team effort on all levels that will create structure, optimize every aspect and stimulate continued improvement of all aspects of StressChron. 5S stand for 5 phases, in Japanese seiri, seiton, seiso, seiketsu and shitsuke.

The 5 phases in short:

  • Sort (Seiri): Know your lab and define what is needed per aspect. Eliminate unnecessary steps, paperwork, materials and obstacles.
  • Set in Order (Seiton): Set up a structured flow. Ensure all necessary aspects and items are arranged in such way that they can be easily used at the location needed. Define locations, itemize, standarize and organize materials, equipment, usables and consumables.
  • Shine (Seiso): Check if the flow is complete and adequate. Maintain high standards in hazard and contamination prevention by keeping workspaces and rooms clean and organised.
  • Standarize (Seiketsu): Work accordingly and orderly. By introducing SOP’s (standard operation procedures) will improve efficiencies, support training and enable quality audits.
  • Sustain (Shitsuke): Sustain the flow and improve where possible. Maintain the 5 principles and introduce MOP’s (measures of performance). Evaluate process and improve.

With implementing the 5S lab management methodology, in combination with ISO 17025, ISO 14001 and ISO 45001, the Stress Physiology Research Group is frontrunning in maintaining the highest possible quality standards.
