This Is In Two Parts Both Parts Should Be Completed And Submitted In

This is in two parts. Both parts should be completed and submitted in a single Word document (.docx) file.

Part 1: List key requirements of your individual design project. Include functional, data, environmental, user characteristics, usability goals, and user experience goals (see page 360 of the text and surrounding pages for more context).

Part 2: Create a hierarchical task analysis for your interface/project (see page 380 for examples and context).

Part 1: Key Requirements of the Design Project

In conceptualizing and designing an effective user interface, it is imperative to identify and articulate the key requirements that will guide the development process. These requirements encompass multiple dimensions including functional needs, data requirements, environmental considerations, user characteristics, usability goals, and user experience (UX) goals.

Functional Requirements

Functional requirements define what the system must do to meet user needs. For a user interface, this includes core capabilities such as data input and output, process execution, user interactions, and system responses. For instance, in designing a mobile banking app, functionalities would include financial transaction processing, balance inquiries, bill payments, and secure login features. These functions form the backbone of the project, ensuring that all essential user tasks can be performed efficiently and reliably.

Data Requirements

Data requirements specify the information that must be managed within the system. This involves data collection, storage, processing, and retrieval. For the banking app, data considerations include customer account information, transaction history, security credentials, and real-time financial data. Ensuring data accuracy, privacy, and security is paramount, particularly given the sensitive nature of financial data.

Environmental Considerations

The environmental context involves physical and technical factors that influence interface design. Environmental considerations include device types (smartphones, tablets, desktops), ambient lighting conditions, network reliability, and hardware capabilities. For example, designing for mobile devices requires attention to smaller screen sizes and touch interactions, whereas desktop interfaces might prioritize larger displays and keyboard functionalities. Additionally, environmental factors like noise levels and lighting impact usability and should be considered during testing and deployment.

User Characteristics

Understanding the target user demographic is critical. User characteristics encompass age, technical proficiency, language, physical abilities, and accessibility needs. For a banking app, target users may range from tech-savvy millennials to older adults who require simplified interfaces and assistive technologies. Tailoring the interface to accommodate diverse user groups enhances usability and inclusivity.

Usability Goals

Usability goals focus on making the system effective, efficient, and satisfying to use. These include reducing task completion time, minimizing errors, providing clear feedback, and ensuring ease of navigation. For instance, minimizing the number of steps required for a transaction and offering real-time confirmation messages can significantly improve usability.

User Experience (UX) Goals

UX goals extend beyond usability to encompass the overall emotional and experiential aspects of interaction. Goals may include creating an engaging, trustworthy, and aesthetically pleasing interface. For a banking app, establishing a sense of security and confidence is vital, along with fostering a smooth and enjoyable user journey, thereby encouraging continued use.

Part 2: Hierarchical Task Analysis for the Interface/Project

Hierarchical task analysis (HTA) is a methodical approach for decomposing user tasks into sub-tasks and actions, providing clarity on the steps users take to complete goals within an interface. This analysis aids in identifying potential usability issues and optimizing task flows.

Main Task: Conduct a Financial Transaction

- Sub-task 1: Log into the system

- Enter username and password

- Authenticate using two-factor authentication (if applicable)

- Sub-task 2: Navigate to the “Transfer Funds” section

- Access menu options

- Select "Transfer Funds" from available options

- Sub-task 3: Enter transaction details

- Specify recipient account details

- Input transfer amount

- Choose transfer date (immediate or scheduled)

- Sub-task 4: Review transaction

- Confirm details are correct

- View applicable fees and exchange rates (if international)

- Sub-task 5: Complete transaction

- Submit transfer request

- Receive confirmation message

But what are the key actions involved in each sub-task? For example, during "Enter transaction details," actions include typing account numbers, selecting options, or scanning QR codes.

- Sub-task 6: Logout securely

This detailed hierarchical breakdown ensures that each step is logically organized, facilitating interface design that aligns with user mental models and minimizes errors. For instance, clear navigation paths and confirmation prompts at each step can improve usability.

Developing the HTA allows designers to visualize the entire workflow, identify redundant or complicated steps, and streamline processes. Incorporating user feedback during the analysis phase can further enhance the intuitive flow of tasks, leading to more user-centered and effective designs.
