RRS (an acronym for Runners, Repeaters and Strangers) is an analysis tool used to remove excess transportation wastes from your processes. Let’s define each element:
- Runner – A product or process which is carried out most frequently (~80% of the time).
- Repeater – A product or process carried out less often but on a regular basis.
- Stranger – A product or process which are rare and have specific requirements – the demand for these are low or intermittent.
Why is it needed? Many organisations have a large number of jobs to be completed and which are all carried out in the same workplace. So, having all of the necessary tools and equipment can lead to an unorganised workplace – slowing down the business’s productivity. RRS analysis allows parts, equipment and tools to be stored appropriately in order of importance, relevance and necessity (i.e. the products and transactions which occur most frequently, the runners, should have the necessary tools stored in locations which minimise transportation).
How does it work? To identify the runners, repeaters and strangers a Pareto Analysis can be used, a statistical technique used to calculate cumulative counts for each product/process. With the highest count being the runners, then the repeaters and finally the strangers.
What next? After identifying the runners, repeaters and strangers, effort can then be made to work around the runners, accommodating the repeaters and developing strategies for the strangers.
