Key Insights

• 🎨 Design Rationally provides a comprehensive understanding of a computer system's design, including its structural and behavioral aspects.
• 😤 It serves as a communication mechanism for the design team, facilitating decision making and knowledge transfer.
• 🎨 In HCI, where multiple design alternatives exist, design rationale helps in understanding and choosing the most effective design solutions.
• 🎨 The design space analysis and decision representation language are structured approaches used in design rationally.
• 🎨 Psychological design rationale focuses on capturing the consequences of design for the user, supporting natural task performance.
• 🏑 Designers may not have expertise in various fields, so understanding relevant theories and principles is necessary for effective design rationale.
• 🖐️ Standards and guidelines play a role in design rationale, with standards being specific patterns and guidelines offering more general principles.

Questions & Answers

Q: What is design rationally and what does it include?

Design Rationally is the explanation of the structural and behavioral aspects of a computer system. It includes the entire system's architectural description and details about how it is designed, along with its functionality and behavior.

Q: How does design rationally benefit the design team?

Design Rationally serves as a communication mechanism among the design team members, allowing them to understand the decisions made during the design process. It also accumulates knowledge that can be used to transfer successful designs to other situations.

Q: Why is design rational particularly important in HCI?

In HCI, there is often no single best design alternative. Design Rationally helps in dealing with multiple design options and decisions, such as choosing between visible buttons or hidden actions in a menu. It aids in understanding the reasoning behind design choices.

Q: What are the different types of design rationally?

There are process-oriented design rationales, which focus on identifying the main problem and developing potential resolutions. There is also psychological design rationale, which aims to make explicit the usability claims of an interactive system and how it supports user tasks.

Summary & Key Takeaways

• Design Rationally explains the structural and architectural aspects of a computer system, providing a detailed understanding of its design.

• It includes both the reflection and documentation of the design process, making it useful for communication among the design team.

• In HCI, where there are multiple design alternatives, design rationale helps in decision making and the transfer of successful designs.
