Size Estimating Walkthrough PSP's LOC and OLOC counters • Assumption/constraint:

− One physical line = one LOC

− Coding standard followed to assure 1-1

• Simplifying assumption: no comments

• LOC Counter has been done

• OMT (close to UML) domain model Task: Estimate the changes necessary to convert theLOC counter to an Object LOC counter
