4IPS FOR 2EQUIREMENTS -ANAGEMENT
4ABLE SUMMARIZES SOME IMPORTANT TIPS FOR AN EFFECTIVE
REQUIREMENTS MANAGEMENT PROCESS
"EST 0RACTICES
! REAL PROBLEM WITH MANY REQUIREMENTS ENGINEERING PROCESSES IS THAT
THEY DO NOT SCALE WELL ! PROCESS THAT WORKS WITH REQUIREMENTS
MAY EXPLODE WITH 4HE FOLLOWING PRACTICES CAN HELP WITH
MEDIUM TO LARGE SCALE PROJECTS

v 2EQUIREMENTS HIERARCHIES SHOULD BE WELL DEFINED E G PARENT
CHILD RELATIONSHIPS DEPENDING ON THE LEVEL OF ABSTRACTION OF
THE FEATURE OR REQUIREMENT &AILURE TO CREATE A HIERARCHY SUCH
AS A TREE STRUCTURE IN TURN LEADS TO A TWO DIMENSIONAL TRACE
TABLE OF SIZE . ¾ . WHERE . IS THE NUMBER OF REQUIREMENTS
ASSOCIATED WITH TRACES AND AFTER SEVERAL THOUSAND REQUIREMENTS
THE TRACES ARE NO LONGER MAINTAINABLE OR USABLE -ITIGATION
TECHNIQUES INCLUDE THE CREATION OF REQUIREMENT HIERARCHIES IN
THE DATABASE SCHEMA THAT PERMIT DATABASE TRACE QUERIES TO
RETURN A MORE MEANINGFUL SUBSET OF TRACES
v #REATE A GLOSSARY OF TERMS AND USE THE TERMS CONSISTENTLY
THROUGHOUT THE PROJECT &AILURE TO DEFINE A STANDARD GLOSSARY
OF TERMS MAY RESULT IN DIFFERENT TERMS BEING USED TO MEAN THE
SAME THING CAUSING AMBIGUITY AND MAKING IT DIFFICULT TO MINE
FOR TRACE RELATIONSHIPS AT A LATER DATE
v #REATE A PROJECT METAMODEL OR ARTIFACT MODEL AT PROJECT
INITIATION #REATION OF SUCH A MODEL WILL REVEAL ALL THE POSSIBLE
TYPES OF TRACES THAT MAY BE POSSIBLE AND ENABLE THE CREATION OF
AN AUTOMATED IF NECESSARY MANUAL TRACE STRATEGY
