These days, information technology is table stakes. The specific technologies used are merely a means to the solution. Any technology will do so long as it meets the functional and "non-functional" (QoS, uptime, reliability, resilience in face of cyber-attacks, etc) requirements. The critical expertise is in the domain. For example, if the business is insurance, how do you assess adverse claims? How is re-insurance priced? procured? How is re-insurance re-insured? syndication? etc. How to incorporate the works of actuaries, underwriters, investigators, etc. There are hundreds of business edge cases. Knowing their impact and how to address them is what constitutes domain specialization.
