Progress Mutual is a bank with eight branches, based in the West Midlands. Its main business is to provide savings accounts to local people. The bank has been open for nearly 100 years and has over 500 000 customers. Many of these customers use a passbook that lists all of their transactions and is updated every time they visit a branch. A new online banking system has recently been launched and a number of customers have started to use this. As well as a mainframe, the bank has a number of other servers housed in a data centre in its head office. It also has a back-up data centre in an off-site location.
