4O EFFECTIVELY USE METRICS THEY SHOULD BE PLANNED AT THE BEGINNING
OF THE PROJECT )T MAY ALSO BE BENEFICIAL TO RETAIN METRICS POSTPROJECT
AND USE THEM FOR OVERALL ORGANIZATIONAL PROCESS IMPROVEMENT
-ETRICS CAN LOOSELY BE DIVIDED INTO TWO CATEGORIES PROJECT AND
QUALITY 0ROJECT MEASUREMENTS OF USE TO MANAGEMENT ASSIST IN
UNDERSTANDING PROGRESS AND PRODUCTIVITY 1UALITY METRICS PROVIDE
INFORMATION ON THE QUALITY OF THE VARIOUS WORK PRODUCTS %XAMPLE
QUALITY AND PROJECT METRICS ARE DESCRIBED IN MORE DETAIL IN THE
FOLLOWING SECTIONS
0ROJECT -ETRICS
0ROJECT MEASUREMENTS ARE USED FOR DAY TO DAY EVALUATION OF PROJECT
STATUS AND TO DETERMINE THE COMPLETENESS OF AN ARTIFACT OR TASK TO
TRIGGER THE REVIEW PROCESS 0ROCESS MEASUREMENTS AND TOOLS ARE
MUTUALLY INTERDEPENDENT 4HAT IS WITHOUT THE PROCESS THERE COULD BE
NO MEASUREMENTS WITHOUT THE MEASUREMENTS PROJECT PROGRESS AND
WORK PRODUCT QUALITY COULD NOT BE ACCESSED AND WITHOUT TOOL SUPPORT
TAKING MEASUREMENTS WOULD BE EXTREMELY TIME CONSUMING POSSIBLY
TO THE POINT OF BEING IMPRACTICAL 4ABLE LISTS A FEW SUGGESTED PROJECT
METRICS
1UALITY -ETRICS
1UALITY METRICS ARE THOSE METRICS THAT MEASURE THE QUALITY OF
REQUIREMENTS ARTIFACTS INCLUDING THE FINAL PRODUCT BUT DO NOT
NECESSARILY CONVEY INFORMATION ABOUT PROJECT PROGRESS OR PRODUCTIVITY
SEE 4ABLE !S QUALITY IS MEASURED AGAINST A STANDARD QUALITY
STANDARDS NEED TO BE DEFINED IN ORDER TO UTILIZE QUALITY METRICS E G
DOES THE REQUIREMENTS SPECIFICATION MEET OR EXCEED THE STANDARD FOR
GOOD REQUIREMENTS SPECIFICATIONS
