11. Environment corrections
vague or unclear system requirements
additions or modifications accepted
other type of users
real time systems
unclear or complex interfaces with other systems
modifications to other people’s programs
badly defined rules, procedures or standards
ICT-people have no experience with similar projects
system bigger than in previous projects
