The weekly shop has become something of a modern day nightmare with stores asking us to either scan as we shop or use self-service tills . But now one of Britain 's biggest supermarkets has turned its back on technology in favour of human staff manning stores . Morrisons 's new CEO , David Potts , who took over last week has scrapped the Intelligent Queue Management ( iQM ) system used in shops after receiving feedback from customers and staff . Morrisons has ditched its Intelligent Queue Management system in favour of returning to using humans to decide how many checkouts to open in stores . The technology , which was introduced in 2008 , used infrared sensors to determine how many checkouts to open by monitoring the number of customer flowing through the store . It meant that during quieter periods staff could be taken off the tills and placed in other parts of the store . The company 's retail team , along with the new boss , concluded that checkout teams would make better and more balanced decisions compared to the iQM computer system . But while they have brought humans back to monitor queues , the controversial self-scan tills will be here to stay . Ex-Tesco executive Mr Potts , who took over as Morrisons ’ chief executive on March 16 , spoke with customers and staff and after feedback decided to scrap some of the modern day technologies . Morrisons was the only British retailer to use iQM , which used infrared sensors both at the entrance to the store and over each checkout lanes . It was supposed to enable checkout managers to predict exactly when shoppers would arrive at the checkouts so the tills were open for them when they got there . When the iQM system was first rolled out as part of a trial with the promise of cutting customer waiting times it had a five per cent success rate , however , staff claimed the system was pointless . Some took to online job review website Glassdoor to complain , with a department manager in Felixstowe , Suffolk , describing it as ' a waste of time and money ' . The unnamed manager had added : 'It [ the iQM ] messes up all the departments in the store and it has a major knock on effect to all other departments with the waste and markdown and rotation . ' A checkout operator from Portsmouth , writing in October last year , said : 'Morrisons needs to go back to basics . We are a superior supermarket and that 's what we need to install in customers old and new . 'Customers want to be treated . Show them we care more than the other leading stores . ' After listening to colleagues executives have also decided to scrap another computerised system which measures the amount of products scanned every minute by checkout staff . The 'scan rate ' was introduced in 2012 after imposing new time targets of one item every three seconds , which prompted an outcry from members of the public , who branded the supermarket as turning into a 'battery hen farm ' . Mr Potts , a former executive at Tesco , said : 'We intend to be an organisation that listens very hard to its customers and staff and , wherever possible , responds quickly . 'Our colleagues in our stores are best placed to use their experience and personal judgement in deciding how best to serve their customers , keeping queues low at the checkouts and improving the customer ’ s shopping trip . '
The Intelligent Queue Management ( iQM ) system has now been scrapped . Morrisons 's CEO David Potts took over October last year and ditched technology . It used special sensors to determine how many checkouts should be open . But feedback from staff and customers determined it was 'waste of time ' Supermarket has also got rid of 'scan rate ' which counts items scanned . The controversial self-service tills are expected to stay despite changes .
