Although I can't know the specific software development strategy of HSBC, according to the general situation, large financial institutions usually adopt a mixed model in software development, that is, they use both internal development teams and external resources.
Internal development teams are usually responsible for the development of critical business systems and sensitive data to ensure security and data protection. At the same time, HSBC may also cooperate with external software development companies or outsource some non-core business software development work.
One advantage of outsourcing software development is that it can use the technology and experience of external professional teams to speed up the project progress and reduce costs. But outsourcing also needs to pay attention to partner selection and contract management to ensure the quality, safety and confidentiality of the project.
It should be noted that the most accurate and detailed information about a specific HSBC software development strategy may require direct consultation with HSBC or reference to official public information.
