| Sampling Factors: |
Location (Not Relevant: All control systems software are developed in house, in shanghai.)
Customer (Not Relevant: Internal customers only, which should follow the standard processes and has no big impact on develop processes implementation.)
Size (Not Relevant: Standard embedded control systems software development. All has similiar size and duration. Neither product size nor team size has big impact on processes implementation.)
Organizational Structure (Not Relevant: All under the same organization structure in Control Systems Department within Technology Center of AECC CAE.)
Type of Work (Not Relevant: The works are very similiar for control systems software development following the V model from system requirement analysis, system solution design, requirement allocation, software requirement analysis, software design and implementation, software integration and testing, system integration and verification, etc.)
Product Line: Different engine product line has different characteristics and performance, economic targets which drive the control systems development process with big tailoring. |
