INTRODUCTIONBy Ayesha Saeed
ESTIMATING SOFTWARE COSTS
More projects are doomed from poor cost and schedule estimates rather than from technical, political, or development team problems.
Software estimating can be a science, not just an art.
It really is possible to accurately and consistently estimate development costs and schedules for a wide range of projects.
ESTIMATING SOFTWARE COSTS Time Cost Effort Risk Return on Investment
These project elements can describe a software development success or decry a project failure. They also frequently cause management nightmares.
Wide range of software cost estimating tools on the market to help with this process.
COST XPERT
Industry leading software cost estimation tool
Transform plans into concrete and quantifiable results
Cost Xpert is specially designed to help organization improve and manage processes, mitigate risks, and exceed bottom line expectations.
COST XPERT- ADVANTAGES
Easy to use for novices
Sophisticated features for advanced user
Integrates multiple estimating models
Most extensive options for project type, lifecycle and documentation standards
Interfaces with standard management and analysis tools
COMPETITIVE EDGE:
Cost Xpert Tool differentiates itself from competitors by integrating multiple estimation models into one user-friendly solution that provides the most accurate and comprehensive estimates possible.
Cost Xpert can be used to forecast any software development project, regardless of size or objective. The tool has been endorsed by both the private and public sector.
ALGORITHMIC COST MODELING
Cost is estimated as a mathematical function of product, project and process attributes whose values are estimated by project managers
The function is derived from a study of historical costing data
Most commonly used product attribute for cost estimation is LOC (code size)
Most models are basically similar but with different attribute values
COST XPERT EFFORT AND SCHEDULE CALCULATIONS
Algorithmically, Cost Xpert started with the COCOMO models, Revised Enhanced Version of Intermediate COCOMO (REVIC) extensions, and then layered functionality on top of this base.

SLOC
Lines of code (often referred to as Source Lines of Code, SLOC or LOC) is a software metric used to measure the amount of code in a software program.
FUNCTION POINTSFunction Point Analysis is an objective and structured technique to measure software size on the basis of the functionality provided to the user.
EQUIVALENT FUNCTION POINTS
Equiv Function Points=7.67*7 +46.83*10 +2*4 +27*5 +37.33*4 =814.31
EQUIVALENT SLOC
For JAVA 2 estimated SLOC per Function Point=46 soEquivalent SLOC=46*814.31=37458.26=>37459 Lines of code
MEAN
EQUIVALENT POINTS
Equiv Points=Mean Value * F.P Conversion Factor
STANDARD DEVIATION
Std. Dev=Worst-Best 6
FUNCTION POINTS
Function Point Analysis is an objective and structured technique to measure software size by quantifying its functionality provided to the user, based on the requirements and logical design.
External interface files are files that the system creates for use by other applications, or that are created by other applications for input into this system.
FUNCTION POINTS
Function Point Analysis is an objective and structured technique to measure software size by quantifying its functionality provided to the user, based on the requirements and logical design.
Each table in a relational database would be an internal table.
FUNCTION POINTS
Function Point Analysis is an objective and structured technique to measure software size by quantifying its functionality provided to the user, based on the requirements and logical design.
External queries are functions you publish for external use (as in an API) or functions/messages from an external system that you will be using.
FUNCTION POINTS
Function Point Analysis is an objective and structured technique to measure software size by quantifying its functionality provided to the user, based on the requirements and logical design.
External outputs are reports and read only screens.
FUNCTION POINTS
Function Point Analysis is an objective and structured technique to measure software size by quantifying its functionality provided to the user, based on the requirements and logical design.
External inputs are data entry screens or dialogs.
INTERNET POINTS
DOMINO POINTS
UML-USE CASE POINTS
Enter the best, worst and expected estimates of the number of Use Case scenarios that will be ultimately identified
UML CLASS METHODEnter the best, expected and worst case estimate of the number of control classes. Control classes represent coordination and sequencing mechanisms.
MKII FUNCTION PTSThis is a method for analysis and measurement of information processing applications based on end user functional view of the system.
Data entities are logical data structures that contains information meaningful to the user.Count the Input Data Element, the Data entity Types Referenced, and the Output Data Element
OBJECT METRICS
Enter the best, worst and expected estimates for the number of new objects (e.g. classes, components) in the system.
GUI METRICS
Enter the best, worst and expected estimates for the number of GUI metrics used in the system. These include dialog boxes, menus, reports and windows.
CAPABILITY REQUIREMENTSEnter the best, worst and expected estimates for the number of new capability requirements.

LIMITATIONS
Highly extensive estimates needs to be determined which can be complex and tedious.
For example lines of codes, number of queries & functions , working labor and working hours.
Difficult to predict at the start of project.
