Supermarket fans

With a Plebble-rating (PR) of 3.41, Waitrose is the 11th highest performing business on Plebble. Not bad for a supermarket. Why? Well they clearly have some passionate brand advocates. Take a look the graph. It shows that 74% of its ratings on Plebble score between 4 and 5 ('very good' or 'brilliant').

When you compare Waitrose to Tesco's you can see the importance of consistency of service. Tesco's has a PR of 0.36 and is behind its rival Sainsbury's. As you can see from the chart Tesco's does have some strong advocates (38% score 'very good'), but the rest of the ratings are spread across all the scores, with 17% scoring between -5 and -4. This suggests Tesco's struggles to provide consistently good service, something Waitrose manages so well. It will be interesting to see if this finding remains as the sample sizes increase. If you think it's wrong, have your say and rate!
