There are some very good test tools around, and some very good requirements management tools. But all too often, there is little to interface the two.
That wouldn’t be so bad if projects really followed the text book V-model so that project phases were perfectly aligned, such that requirements stayed fixed throughout the development lifecycle, design reflected the requirements perfectly, and implementation fulfilled the design precisely. But they don’t. Changing requirements, coding rule violations, failed unit tests, and a host of other facts-of-life mean a constant flux of feedback between test and requirements management tools, and the resulting need for manual intervention represents a breeding ground for error.
As software becomes more complex, the challenge of demonstrating traceability between phases makes tedious, error-prone, manual methods increasingly unworkable. Automating the interface between DOORS NG and LDRA tools presents one way of turning such a weakness into a strength.
