Firstly I'm a bit confused by the below paragraph......
"The Common Platform Programme (CPP) was supposed to be complete by March 2019 at a total cost of £350m. However, a spokeswoman for HM Courts & Tribunals Service (HMCTS) said the program will not be complete until 2020 at a revised cost of £270m."
Secondly, the introduction of agile was a reaction to the failures of the Waterfall methodology to deliver within budget and on time.
