The software design process
Why Waterfall fails
•Waterfall projects have 3x the failure rate (29% vs. 9%) and 1/3 the success rate (14% vs. 42%) of Agile projects (Standish Group, CHAOS Report 2012)
•Inventor of Waterfall Winston W. Royce described in his academic paper written in 1970 that it was “risky and invites failure” and went on to describe Incremental development.
•Recent failed waterfall projects that scrapped
•UK Govt. £12 Billion for national program for NHS IT
•US Air Force – 6 year project with cost of $1.3 Billion
•QLD Health $1.2 Billion

How will Agile help us?
•Reduce time to market
•Reduce risk by finding errors earlier in the process
•Early access to the software during the life cycle
•Greater flexibility to change
•Early cancellation(or failure) hurts less
•Reduced defect count
•Maintain compliance levels and auditory requirements
•Improved transparency for stake holders/management
