Slow developmentQuality issuesFuzzy project status
Slow development
Constant version delivery date delays
We are unable to estimate some tasks
We are unable to hold TCO of documentation• No srs• Crude design document• Outdated STP• Who updates what and where?
Quality issuesEmbarrassing bugs, but not many
Rigid softwareFragile softwareImmobile codeNeedless repetitions
Needless complexityTests issues• Client has no tests• Server has some tests
