I am new to function point(FP) estimation. I am considering the following cases would be considered as External Inquery(EQ)/ External Output(EO) in function point sizing perspective. Please correct me if I am wrong.
- Lookup of hard coded country code in a master data entry screen.
- Master data information maintained by a system
- lookup of a language code information that is hard coded in the application
Any notification/error message comes out of a system would be considered as External Input(EI) only because EI is maintains round trip in nature (batch job may be the exception) and the notification/error message is a part of the round trip. Is my understanding correct?
For Non functional requirement estimation can we use FP technique or Use case estimation technique?
