Can you explain in GSC and VAF in function points
Can you explain in GSC and VAF in function points?
In GSC (General System Characteristic) there are 14 factors which are rated on 1 to 5
depending on the complexity of the factor. Below are the 14 factors:
Data communications: - How many communication facilities are there to aid in the transfer or exchange of information with the application or system?
Distributed data processing: - How are distributed data and processing functions handled?
Performance: - Did the user require response at times or throughout?
Heavily used configuration: - How heavily used is the current hardware platform where the application will be executed?
Transaction rate:-How frequently are transactions executed; daily, weekly, monthly, etc.?
On-Line data entry:-What percentage of the information is entered On-Line?
End-user efficiency:-Was the application designed for end-user efficiency?
On-Line update: - How many ILFfs are updated by On-Line transaction?
Complex processing:-Does the application have extensive logical or mathematical processing?.
Reusability:-Was the application developed to meet one or many users needs?
Installation ease: - How difficult is conversion and installation?
Operational ease: - How effective and/or automated are start-up, back up, and recovery procedures?
Multiple sites: - Was the application specifically designed, developed, and supported to be installed at multiple sites for multiple organizations?
Facilitate change: - Was the application specifically designed, developed, and supported to facilitate change?
From the GSC we get the VAF i.e. Value added function points by the below formulae.
VAF = 0.65 + ((sum of all GSC factor)/100).
