Create a "maker-checker" functionality within a finance platform for all manual operations, ensuring that each action is carried out by two distinct individuals: the executor and the approver.

This inquiry represents a standard product design challenge, requiring the interviewee to suggest a viable solution for implementing a "maker-checker" feature within a financial platform. The 'maker-checker' concept, from a controls standpoint, stipulates that at least two individuals must be involved in completing each transaction. The 'maker' is the first individual who initiates the transaction, while the second individual, known as the 'checker' or 'approver', reviews and authorizes the transaction's completion. When addressing this question, focus on the following essential aspects: Grasping the feature's purpose: It is intended to reduce risk and prevent fraudulent activities and mistakes in financial transactions. Defining the roles: Clarifying the responsibilities associated with each role - the 'maker', who initiates the transaction, and the 'checker', who approves it. Outlining the process: Describe the steps from initiating a transaction to its finalization. Considering edge cases: Reflect on situations such as the unavailability of one person or attempts to circumvent the system.

The "maker-checker" concept is implemented to guarantee the accuracy of transactions and plays a significant role in preventing fraud and errors. Roles : In this framework, the 'Maker' or executor is tasked with performing an operation or task. The 'Checker' or Approver is in charge of verifying or approving the operation. Process : Initially, the Maker starts a transaction. Once completed, a notification will be sent to the Checker. The Checker then examines the process carried out by the Maker and either approves it or returns the request with feedback. Upon approval, the transaction is processed. If it is rejected or sent back, the Maker addresses the concerns raised by the Checker, corrects them, and resubmits the transaction. Edge Case Consideration : If a Maker or Checker is unavailable, the system can be configured to permit a secondary Checker or an escalated approval process to maintain the continuity of the procedure while adhering to the "maker-checker" principle.

Here’s an alternative approach to implementing a "maker-checker" feature in a financial platform: Roles : Maker: This role is responsible for initiating the transaction. Checker (also referred to as Verifier or Approver): This role reviews the work completed by the Maker to ensure its accuracy. Process : The Maker submits a request for a financial transaction, including all necessary details. An automatic alert/notification is sent to the Checker. The Checker reviews the request, deciding whether to accept or reject it. The Checker may also send it back to the Maker with a request for modifications. If the Checker approves the request, the transaction proceeds; if it is rejected, the Maker must begin the process anew. Edge Case Consideration : It is important to incorporate a feature to manage situations where the Checker is unavailable. An approval matrix could be implemented, allowing a secondary Checker to take over if the primary Checker is not present, or escalating the request up the leadership hierarchy.
