Last week I was reminded of my aeons ago primary school experience of having to bring in something for the 'nature table' and then being made to stand up and show it to my classmates and tell them about it. I liked the clump of sheep's wool I'd pulled off some barbed wire complete with all the claggy bits of mud and twigs – but I got no takers to my offer of giving them some of it to show their mums and dads.
Nowadays this type of thing is called a 'show and tell' which Netmums tell us 'is a key part of the school day and an important part of your child's learning development, as it helps them to organise information and builds their confidence.'
The 'show and tell' (aka sprint review) that I was in was somewhat similar: a valiant presenter and polite audience. These 'show and tell' events are a key part of agile methodology giving the team the time 'to present the work completed during the sprint. The Product Owner checks the work against pre-defined acceptance criteria and either accepts or rejects the work.' A show and tell, however, 'is not a meeting designed to criticise or for the team to take further actions for improvement to the product.'
