SOME OF THE -2S WILL RESULT IN CHANGES TO REQUIREMENTS OR OTHER
ARTIFACTS 4HE ##" IS ANALOGOUS TO AN ENGINEERING REVIEW BOARD %2"
THAT IS USED TO REVIEW PROPOSED CHANGES TO THE FORM FIT OR FUNCTION OF
THE ELECTRICAL COMPONENTS IN ELECTRONICS DESIGN AND MANUFACTURING )N
THIS CASE ENGINEERING CHANGE REQUESTS %#2S ARE MADE ANALYZED AND
SOME OF THE REQUESTS ARE IMPLEMENTED AS ENGINEERING CHANGE ORDERS
%#/S ! SUMMARY OF THE DECISION MAKING COMPONENTS FOR
REQUIREMENTS ENGINEERING CHANGE MANAGEMENT IS GIVEN IN 4ABLE
4HE DEGREE OF FORMALITY IN CHANGE MANAGEMENTE G THE MAKEUP
OF ANY ##"IS A FUNCTION OF THE NATURE OF THE PROJECT CONTRACT OR THE
LIKE &OR EXAMPLE IN RESEARCH PROJECTS FREQUENT CHANGES ARE SOMETIMES
EXPECTED AND CONSEQUENTLY REVIEWS MAY BE FREQUENT AND INFORMAL
/N THE OTHER HAND SOME PROJECTS REQUIRE THE DELIVERY OF
ELECTROMECHANICAL SYSTEMS WITH WELL DEFINED SOFTWARE AND HARDWARE
FEATURES E G A RAILROAD SIGNALING SYSTEM WHERE UNAUTHORIZED FEATURE
CHANGES CAN HAVE A CATASTROPHIC EFFECT ON THE PROJECT S BOTTOM LINE OR
DELIVERY DATE SO THESE SYSTEMS MUST HAVE FORMAL ##" PROCESSES
3EVERAL DIFFERENT TYPES OF ANALYSES ARE DONE BY THE MEMBERS OF A
CHANGE CONTROL BOARD OR PROJECT MANAGEMENT STAFF TO SUPPORT CHANGE
MANAGEMENT .OTE THAT ANY KIND OF ##" ANALYSIS RELIES ON IN PLACE
TRACEABILITY MECHANISMS 4HEY WILL BE DISCUSSED IN THE NEXT SECTION !
