- Work Breakdown Structure Three Point Estimate effort of Activity = ((Most probable Value * 4) + Pessimistic Value + Optimistic Value)/6 2. Lines of Code Measure after the coding phase Measure at the beginning of maintenance or conversion project 3. Delphi several engineers individually produce estimates and converge on a consensus estimate at last. 3.1 A group of experts is each given the program's SPECs and estimation form 3.2 the experts discuss 3.3 anonymously list project tasks and a size estimate 3.4 moderator collects the estimates and tabulates the results and return them to the experts 3.5 only each expert's personal estimate is identified; all others are anonymous. 3.6 experts discuss and review the tasks 3.7 continues from step 3.3 again utill converge to within an acceptable range 4. Function Point Five aspects considered: * External Inputs(EIs), Add&Update&Delete Records * External External Outputs(EOs), Records Summary&Details * External Inquiries(EQ),an input/output flow where input immediately generates the output, no logical data files modified * Internal logical files(ILFs),maintained data model entity * External Interface files(EIFs), maintained outside of the application step1: determine the type of project: development project, enhancement project,installed application step2: identify the Counting Boundary step3: determine an unadjusted function point count step4: Determine a value adjustment factor step5: Calculate the adjusted function point count
