Final Projectlong Assignment Due By May 15th 2020the Goal Of This Fi

Final Project/Long Assignment Due by May 15th, 2020 The goal of this final project is to design a simulated automated teller machine (ATM) for a bank. For this project, you can think that all the customers who are using the system will be associated with the bank (i.e., the ATM system will not recognize an ATM card which is not associated with this bank). As soon as a customer opens an account with this bank, they receive a valid ATM debit card. The machine will be able to read from the magnetic stripe reader of the debit card, will have a customer console (keyboard and display) for interaction with the customer, a slot for depositing envelopes, a dispenser for cash (in multiples of $20), a printer for printing customer receipts, and a key-operated switch to allow an operator to start or stop the machine.

Your deliverable for this project is to:

– Highlight the major project features as part of the Business Requirements Document (BRD) and elaborate on the project scope in the Functional Specification Document (FSD).

– Justify the choice of software development methodology suitable for resolving the problem and explain the reasoning. Discuss whether any components will be outsourced and specify which outsourcing model will be utilized.

– Provide a detailed design document using UML diagrams (selecting appropriate UML models).

– Develop detailed test cases based on the design document.

– Conclude with an implementation or communication plan.

Paper For Above instruction

The development of an Automated Teller Machine (ATM) designed specifically for a single bank presents unique design and implementation challenges that require thorough planning and precise specifications. This paper details the major features of the project, explores the scope, justifies the development methodology, discusses outsourcing strategies, and offers UML-based design models and test cases to ensure a robust system.

Project Features and Scope

The core features of the ATM system include secure account access via magnetic stripe card reading, customer interaction through a user-friendly interface, cash dispensing in specific denominations, deposit envelope acceptance, receipt printing, and operational control via an operator switch. The system must integrate with the bank's existing customer database for authentication and transaction processing. The scope encompasses user authentication, account management, cash withdrawal, deposit handling, receipt generation, and operational security controls.

The system's primary functionality is to facilitate banking transactions such as cash withdrawals and deposits, account inquiries, and transaction receipts. It must adhere to security standards to prevent unauthorized access, incorporate real-time transaction processing, and log all activities for auditing purposes.

Development Methodology Justification

For this ATM system, an Agile development methodology is recommended due to its flexibility and iterative nature, which is suitable for developing secure, user-centered systems. Agile allows continuous stakeholder feedback during development, ensuring that user requirements are accurately captured and implemented. Given the complexity of security requirements, iterative testing and feedback loops facilitate early detection of vulnerabilities and usability issues.

Outsourcing components—such as the manufacturing of hardware modules like the cash dispenser or card reader—can be advantageous. The outsourcing model best suited is the Design and Build model, where external vendors are responsible for hardware components based on precise specifications, allowing the internal team to focus on software development and integration.

Design Documentation Using UML

The system design adopts several UML diagrams:

  • Use Case Diagram: Illustrates interactions between users (customers, operator) and the ATM system, including login, withdrawal, deposit, receipt printing, and system maintenance.
  • Class Diagram: Defines key classes such as Customer, Account, Transaction, ATM Machine, CashDispenser, CardReader, ReceiptPrinter, and OperatorControl, along with their attributes and methods.
  • Sequence Diagram: Captures the flow of actions during a typical transaction, such as customer authentication, cash withdrawal, or deposit.
  • State Diagram: Represents the states of the ATM machine, including Idle, Authentication, TransactionSelecting, Processing, and OutOfService.

Test Cases Derived from Design

Test cases are crafted to verify each functional component and system transition. Examples include:

  1. Test Customer Authentication:
    • Input valid account number and PIN; expect access granted.
    • Input invalid PIN; expect error message and retry option.
  2. Test Cash Withdrawal:
    • Request withdrawal of an amount within the account balance; confirm cash dispensed and balance updated.
    • Request amount exceeding account balance; expect transaction denial.
  3. Test Deposit:
    • Insert valid deposit envelope; expect deposit credited and receipt printed.
  4. Test System Out-of-Service:
    • Simulate operator switching system off; expect ATM to display out-of-service message.

Conclusion and Implementation Plan

The implementation involves phased deployment starting with a prototype, rigorous testing, and user acceptance testing. The communication plan emphasizes stakeholder engagement through detailed documentation, demonstrations, and training sessions. Post-deployment support includes monitoring transaction logs, security audits, and routine maintenance to ensure system reliability and security.
