| Sampling Factors: |
Location (Not Relevant: All projects use the same processes at all locations)
Customer (Not Relevant: Processes aren”t different for different customers)
Size (Not Relevant: All projects use the same processes regardless of size)
Organizational Structure (Not Relevant: All departments use the same processes)
Type of Work: L1 project software controls machines directly, L2 provides Operator/System interface to control L1 software in devices; both means that L1 and L2 software is included in the project. The processes used for these three types of development have differences. |
| Sampling Factor Values: |
L1 (Type of Work): Embedded software that controls machines
L2 (Type of Work): Control software, that controls L1 software in machines
L1 & L2 (Type of Work): Combined Level 1 and Level 2 projects, that include the machine code as well as the control and HMI software |

L1: Production line automation software
12 People, 5 Basic Units
– L1
L2: User interface and production line control
7 People, 3 Basic Units
– L2
L1 & L2: Combined production line control and automation
14 People, 3 Basic Units
– L1 & L2 |
