| Sampling Factors: |
Location (Not Relevant: There are four locations but with no impact on how ML2 processes are being performed)
Customer (Not Relevant: There are different customer groups (external/internal, OEMs/suppliers, region (Chinese/other Asian/European(North American)) but with no impact on how ML2 processes are being performed)
Size (Not Relevant: There are 3 different project size categories Small: 0-20.000€. They don’t work according to CMMI processes Medium: up to 3.000.000€; large: more than 3.000.000€) Size has no impact on how ML2 processes are being performed.)
Organizational Structure (Not Relevant: BE and BT have different products and work for different customers but this makes a difference for engineering only, no impact on how ML2 processes are being performed)
Type of Work (Not Relevant: Pure sw development, system projects consisting of sw and hw subprojects. There is no impact on how ML2 processes are being performed.)
Project structure: Relevant is the project structure: There are complex projects with two levels of management and simple projects with just one level of management. This has an impact on how PP, PMC, REQM are performed. |
| Sampling Factor Values: |
Complex (Project structure): Two levels of management (Overall project, subprojects such as software, hardware, etc)
Simple (Project structure): One level of management (software only projects) |
| Subgroups: |
Complex projects: Two levels of management (project management and subproject management where subprojects may sometimes be just one person)
65 People, 4 Basic Units
– Complex
Simple projects: One level of management, i.e., the project is one homogenous group (which is sw development)
63 People, 11 Basic Units
– Simple |
