Discussion on Function size measurement in 5WCSQ

Time:2011-11-1 about 16:00~17:15
attendee:
Makoto Nonaka Toyo University, Zhang Keqiang DNV, Ning Dejun IBM ,
Zhu Min Fujitsu, Elwin Xu CDC software , William Zeng Sungard, A girlwho left early

1,Investigation:which function size measurement method do your
organization use?
IFPUG Function Point
Use case point
story point
Nasma FP
CSK customized FP
Cosmic -FFP
man-day
ideal man-day
scope point
KLOC

2, what about Japan in function size measurement
Makoto Nonaka show a database.
There are total 2850 project in database.
IFPUG 388
SPR 263
NESMA试算 2
NESMA概算 112
COSMIC 1
other 428
Blank 1653

3， How to estimate the project's size?
1,use the above size measurement methods
2,use analogy-based estimation, compare the similar project
according to the historic data which need collect many parameters of a
project.

4, Japan have a IPA/SEC organization, this organization will publish 软件
开发数据白皮书。 it can be searched on the internet.

5, example for productivity in 软件开发数据白皮书
Log(工数)=1.156*Log(FP)+0.542
工数 = e的0.542次方*FP的1.154次方 = 1.719*FP的1.154次方
(Keqiang: I guess that the unit of 工数 is work-hour.)

all infomation about Japan is provided by Makoto Nonaka. Thank Makoto
Nonaka very much.
