Help ABC Bank pick a solution

We've been asked by our clients at ABC Bank for help in choosing a technical solution.

• Regulators have asked the bank to demonstrate how an order executed by a trader flows from system to system and eventually ends up on a financial report.
• The process has been extremely manual and time-consuming, and the bank wants to know if there is a way to speed up the process.
• They have the budget for two technical solutions. Which would you recommend?
