The IT systems and applications are everywhere now, from simple to complex systems to run basic data entry to control autonomous cars and autonomous planes and more complicated systems.
Unfortunately, after a lot of research in software process models and project management frameworks, Software and IT projects still have a very high failure rate. According to a study has been made by Mckinsey in 2012
On average, large IT projects run 45% over budget and 7% over time while delivering 56% less value than predicted. That’s beside the common issues of deliverable quality of final software product according to specifications.
