Project Management - Why Waterfall Sucks

You agree with me or not, but following are the limitations and drawbacks of waterfall approach, I have noticed through-out my career.

Serialized Process: MRD - PRD - Design Document - Dev - QA

Longer time to market; developers isolated from customer needs

Planning Far in Advance

Plans no longer match reality by the time they're implemented

Lack of Visibility into Rate of Progress

Teams don't realize they're behind schedule until too late
Features slashed very late to compensate, wasting effort and leading to Swiss-cheese products (e.g. MS Kin)

Long time to project completion

Customers get access to new features infrequently and after long delay

Projects Fall Behind Schedule

Projects miss market window or are killed before launch


Let me know what do you think?
