Usage
KitchenhamMadeyskiBudgen16.COCOMO
Format
A data frame with variables:
- Project
Project ID
- Type
A categorical variable describing the type of the project
- Year
The year the project was completed
- Lang
A categorical variable describing the development language used
- Rely
Ordinal value defining the required software reliability
- Data
Ordinal value defining the data complexity / Data base size
- Cplx
Ordinal value defining the complexity of the software / Process complexity
- Aaf
??
- Time
Ordinal value defining the stringency of timing constraints / Time constraint for cpu
- Stor
Ordinal value defining the stringency of the data storage requirements / Main memory constraint
- Virt
Virtual Machine volatility
- Turn
Turnaround time
- Type2
A categorical variable defining the hardware type: mini, max=mainframe, midi
- Acap
Ordinal value defining the analyst capability
- Aexp
Ordinal value defining the analyst experience / application experience
- Pcap
Ordinal value defining the programming capability of the team / Programmers capability
- Vexp
Ordinal value defining the virtual machine experience of the team
- Lexp
Ordinal value defining the programming language experience of the team
- Cont
??
- Modp
/ Modern programming practices
- Tool
Ordinal value defining the extent of tool use / Use of software tools
- ToolCat
Recoding of Tool to labelled ordinal scale
- Sced
Ordinal value defining the stringency of the schedule requirements / Schedule constraint
- Rvol
Ordinal value defining the requirements volatility of the project
- Select
Categorical value calculated by BAK for an analysis example
- Rvolcat
Recoding of Rvol to a labelled ordinal scale
- Modecat
Mode of the projects: O=Organic, E=Embedded, SD-Semi-Detached
- Mode1
Dummy variable calculated by BAK: 1 if the project is Organic, 0 otherwise
- Mode2
Dummy variable calculated by BAK: 1 if the project is Semi-detached, 0 otherwise
- Mode3
Dummy variable calculated by BAK: 1 if the project is Embedded, 0 otherwise
- KDSI
Product Size Thousand of Source Instructions
- AKDSI
Adjusted Product Size for Project in Thousand Source Instructions - differs from KDSI for enhancement projects
- Effort
Project Effort in Man months
- Duration
Duration in months
- Productivity
Productivity of project calculated by BAK as AKDSI/Effort, so the the larger the value the better the productivity
