Assignment 2 Use Casesdue Week 6 And Worth 200 Points

As an intern software developer for a retail bank, you have been tasked with developing use cases to support the ATM service. Prepare a 5-6 page paper in which you:

Describe (in a one to two (1-2) page narrative) a use case, complete with typical and alternate courses, that documents the event of a bank customer withdrawing money from an ATM. Illustrate the use case using Visio or a similar product.

Describe (in a one to two (1-2) page narrative) a use case dependency for making an account deposit. Illustrate this use case with Visio or a similar product.

Describe (in a one to two (1-2) page narrative) a use case dependency for making an account transfer. Illustrate this use case with Visio or a similar product.

Identify and explain at least one (1) ethical issue that the use case exposes in connection with the development or use of the ATM system. Research and cite at least three (3) authoritative academic sources.

Your assignment must: Be typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format.

Include charts or diagrams created in Excel, Visio, MS Project, or similar tools such as Open Project, Dia, or OpenOffice. The completed diagrams/charts must be imported into the Word document before submission.

Introduction

Understanding use cases is fundamental to systems analysis and development, especially when designing user-centric functionalities such as ATM services in banking. Use cases serve as vital tools that describe interactions between users and systems, ensuring that all functional requirements are captured accurately. This paper explores three specific use cases within the context of ATM operations in a retail bank: ATM cash withdrawal, account deposit, and account transfer. Moreover, it discusses the dependencies among these use cases and addresses the ethical considerations intrinsic to ATM system development and deployment.

Use Case for ATM Cash Withdrawal

The process of withdrawing cash from an ATM encapsulates a series of interactions between the customer and the banking system. The primary goal is to enable a customer to withdraw a specified amount securely and efficiently. The typical course begins with the customer inserting their debit card into the ATM and entering their PIN. Upon successful authentication, the system prompts the user to select the withdrawal option and input the desired amount. The system then verifies sufficient account balance before dispensing cash. If sufficient funds are available, the ATM dispenses the money, updates the account balance, and prompts the user for further transactions or to end the session. Alternate courses include scenarios such as incorrect PIN entry, insufficient funds, or technical errors in cash dispensing.

In Visio, this use case can be illustrated with actors such as Customer and ATM System, along with process steps including Insert Card, Authenticate PIN, Select Withdrawal, Enter Amount, Verify Funds, Dispense Cash, and End Session.

Use Case Dependency for Making an Account Deposit

The deposit use case depends on the system's capability to accept, verify, and record deposited funds. When a customer chooses the deposit option, they insert cash or checks into the ATM, followed by entering their account credentials. The system verifies the account status, accepts the deposit, updates the account balance, and issues a receipt. This process depends on the prior authentication use case to ensure user identity. In diagram form, actors include Customer and ATM System, with process steps: Insert Deposit, Authenticate User, Verify Deposit, Record Transaction, and Provide Receipt.

Use Case Dependency for Making an Account Transfer

The account transfer process is more complex, requiring validation of both source and destination accounts. The customer initiates the transfer by selecting the transfer option, entering source and destination account details, and specifying the transfer amount. The system verifies account validity, checks for sufficient funds in the source account, processes the transfer, updates both accounts, and confirms the transaction. This use case relies on prior authentication and account verification use cases. Visio diagrams would depict actors such as Customer and ATM System, with sequence steps including Authenticate User, Select Transfer, Enter Accounts and Amount, Verify Funds, Transfer Funds, and Confirm Transfer.

Ethical Issue in ATM System Development

A significant ethical issue related to ATM systems concerns data security and privacy. Ensuring the confidentiality of customer information, such as PINs and account data, is crucial. Any breach or vulnerability could lead to identity theft or financial fraud. Developers must ethically safeguard sensitive data, employing encryption and secure authentication methods, respecting customer privacy rights, and preventing unauthorized access. Furthermore, ethical considerations include transparency about data usage and compliance with banking regulations and data protection laws.

Research indicates that breaches of data security in banking systems undermine customer trust and potentially cause financial and reputational damage (Kumar et al., 2020). Ethical responsibility mandates that developers implement robust security measures and adhere to legal standards to uphold customer rights and maintain system integrity.

Conclusion

The development of use cases such as ATM cash withdrawal, deposits, and transfers is integral to designing functional and efficient banking systems. Understanding dependencies among these use cases enhances system coherence, while awareness of ethical considerations ensures responsible system development. Incorporating these elements facilitates creating secure, user-friendly banking services that uphold customer trust and align with legal standards.
