Special features Function point approach is independent of the language, tools, or methodologies used for implementation i.e. External Inquiry (EQ): An EQ is an elementary process that is made up to an input output combination that result in data retrieval. External Output (EO): An EO is an elementary process that generate data or control information to be sent out side the system. The EI is an elementary process, which is the smallest unit of activity that is meaningful to the end user in the business. (ii) Transactional function types External Input (EI): An EI processes data or control information that comes from outside the system.

This means that EIF counted for one system, may be an ILF in another system. External Interface files (EIF): A user identifiable group of logically related data or control information referenced by the system, but maintained within another system. The five functional units are divided in two categories: (i) Data function types Internal Logical Files (ILF): A user identifiable group of logical related data or control information maintained within the system. The FPA functional units are shown in figure given below: ILF EIF User Other applications System Outputs Inputs Inquiries ILF: Internal logical files EIF: External interfaces FPAs functional units System

Inputs : information entering the system Outputs : information leaving the system Enquiries : requests for instant access to information Internal logical files : information held within the system External interface files : information held by other system that is used by the system being analyzed. The principle of AlbrechtвЂ™s function point analysis (FPA) is that a system is decomposed into functional units. By this definition, figure shown above has 17 LOC.ДЇunction Count Alan Albrecht while working for IBM, recognized the problem in size measurement in the 1970s, and developed a technique (which he called Function Point Analysis), which appeared to be a solution to the size measurement problem.

This is the predominant definition for lines of code used by researchers. This specifically includes all lines containing program header, declaration, and executable and non-executable statementsвЂќ. вЂњA line of code is any line of program text that is not a comment or blank line, regardless of the number of statements or fragments of statements on the line. One can easily see the potential for major discrepancies for large programs with many comments or programs written in language that allow a large number of descriptive but non-executable statement. The differences in the counts are 18 to 17 to 13. The only executable statements in figure shown above are in lines 5-17 leading to a count of 13.

When comments and blank lines are ignored, the program in figure shown below contains 17 LOC.Д¦ Software Project Planning Growth of Lines of Code (LOC)ДЇurthermore, if the main interest is the size of the program for specific functionality, it may be reasonable to include executable statements. If LOC is simply a count of the number of lines then figure shown below contains 18 LOC. The various steps of planning activities are illustrated shown below : Size estimation Cost estimation Development time Resources requirements Project scheduling Software planning begins before technical work starts, continues as the software evolves from concept to reality, and culminates only when the software is retired. In order to conduct a successful software project, we must understand: Scope of work to be done The risk to be incurred The resources required The task to be accomplished The cost to be expended The schedule to be followed Also, in many cases, customer may like to know the cost and development time even prior to finalisation of the SRS. Presentation on theme: 'Software Project Planning.'- Presentation transcript:ДЄfter the finalisation of SRS, we would like to estimate size, cost and development time of the project.
