||Location (Not Relevant: Although there are different locations for software development (1 on customer site, 2 in OU), but there is no process difference since they all follow the same processes after tailoring.)
Customer (Not Relevant: 1 project has internal customer, the other 2 are external government customer. The difference is covered by Type of Work.)
Size (Not Relevant: Although projects are with different sizes, but there is no process difference for different sizes since they all follow same processes after tailoring.)
Organizational Structure (Not Relevant: All 3 projects are within R&D Department, there is no significant process differences after tailoring.)
Type of Work: There are 2 types of work: Internal development and contract-based development. Contract-based development faces external customer with signed contract, while internal development has internal customer without signed contract. This creates process differences in project kickoff, feasibility analysis, architecture design, testing, and tools used.
