v 0LAN FOR NAVIGATIONAL FACILITIES !S PROJECTS GET LARGE THE
VOLUME OF DOCUMENTATION ASSOCIATED WITH THE PROJECT CAN
MAKE DOCUMENT MANAGEMENT UNWIELDY &OR EXAMPLE WHAT
HAPPENS IF A REQUIREMENT IS ADDED THAT CROSS CUTS OTHER
REQUIREMENTS .AVIGATION TECHNIQUES SHOULD BE DEFINED THAT
WILL ENSURE THAT IMPORTANT INFORMATION IS NOT LOST AND THAT
THERE IS NO DUPLICATION OF EFFORT
v #AREFULLY DEFINE THE REQUIREMENTS DATABASE SCHEMA
2EQUIREMENTS DATABASES ARE A GOOD SOURCE OF PROJECT METRICS
BUT QUERY RETRIEVAL IS ONLY AS GOOD AS THE METRICS BUILT IN AND
ADHERENCE TO THE PROCESS TO RECORD THEM &OR EXAMPLE
v 0ERCENT OF REQUIREMENTS FAILING REVIEW BECAUSE OF
AMBIGUITY !N EXCESSIVE NUMBER OF REQUIREMENTS THAT
DO NOT PASS REVIEW BECAUSE OF AMBIGUITY INDICATES THAT
ANALYSTS HAVE NOT HAD ENOUGH TRAINING IN REQUIREMENTS
WRITING OR PERHAPS NEED ADDITIONAL MENTORING !MBIGUOUS
REQUIREMENTS ARE A MAJOR SOURCE OF SOFTWARE DEFECTS
v 0ERCENT OF REQUIREMENTS FAILING REVIEW BECAUSE OF
INCOMPLETENESS 4HIS CAN BE AN EARLY INDICATOR OF SEVERAL
PROBLEMS NOT ENOUGH TIME IS BEING SPENT ON THE ANALYSIS
PHASE OF THE PROJECT ANALYSTS MAY BE TIME BOXED OR RUSHED
TO DELIVER OR SUBJECT MATTER EXPERTS ARE NOT AVAILABLE
SUFFICIENTLY TO CLARIFY THE MATERIAL
v 0ERCENT OF REQUIREMENTS COVERED BY TEST CASES 4HIS IS A
MEASURE OF PROJECT PROGRESS )F AUTOMATED TRACING
MECHANISMS ARE IN PLACE A PROJECT DASHBOARD CAN BE
CREATED TO DISPLAY INDICATORS OF PROJECT PROGRESS
v )NCLUDE BUSINESS GOALS AND POLICIES IN CHANGE MANAGEMENT
DEFINE BUSINESS ARTIFACTS SUCH THAT REQUIREMENTS TRACES CAN
FLOW BACK TO ORIGINATING POLICIES OR GOALS
3UMMARY
)N THIS CHAPTER WE HAVE INTRODUCED SOME OF THE PRACTICES USED FOR
REQUIREMENTS MANAGEMENT 4HESE PRACTICES BECOME INCREASINGLY
IMPORTANT AS PROJECTS GROW LARGER 2EQUIREMENTS AND 2% ARTIFACTS
MUST BE CONTROLLED AND TRACED 7HEN CHANGES ARE PROPOSED PROCESSES
MUST BE USED TO ANALYZE THE IMPACTS OF THE CHANGES
