…the implementation described [is] risky and invites failure. The testing phase which occurs at
the end of the development cycle is the first event for which timing, storage, input/output
transfers, etc., are experienced as distinguished from analyzed. [If] these phenomena fail to satisfy
the various external constraints, then invariably a major redesign is required. [The] required design
changes are likely to be so disruptive that the software requirements upon which the design is
based and which provides the rationale for everything are violated. Either the requirements must
be modified, or a substantial change in the design is required. In effect the development process
has returned to the origin and one can expect up to a l00-percent overrun in schedule and/or
costs.
