Overview
This book addresses the fundamental challenges of building high-quality, user-friendly software by exploring the often conflicting priorities of user-centered design and software engineering.
My primary audience is managers of user-interface programming projects, those most responsible for balancing these conflicting priorities. Students of programming considering a career in user-interface development will also find the book’s interdisciplinary approach valuable. Additionally, the book serves as a call to action for software engineers and researchers to bridge the gap between their respective disciplines and embrace a more human-centered approach to software development.
My central argument is that while traditional software engineering principles are essential for building robust and maintainable systems, they are often insufficient, even counterproductive, when applied to user interfaces. Users are unpredictable, their needs are often poorly understood by developers, and the iterative nature of user interface design often clashes with the structured, pre-planned approach favored by software engineers. I explore this clash through a variety of real-world anecdotes, horror stories, and case studies, drawing on my own experience leading the user-interface component of the Andrew Project.
I propose a set of principles and practices for building user-centered software that acknowledges the limitations of both software engineering and user interface design. These principles emphasize iterative design, user feedback, the importance of simplicity and flexibility, and the need to cater to both novice and expert users. I also discuss the crucial but often underestimated role of non-technical stakeholders, such as managers and lawyers, in shaping software design.
Finally, I offer a framework for human-oriented software engineering, a hybrid approach that combines the best practices of both disciplines. This framework emphasizes iterative prototyping, user testing, and ongoing feedback as essential components of the development process, recognizing that user interfaces are constantly evolving artifacts, and successful design requires continuous adaptation and refinement. This framework, while not a guaranteed recipe for success, offers a practical approach for managing the complex human element in software development and increasing the likelihood of creating software that is both user-friendly and well-engineered.
Book Outline
1. The Hostile Beast
Building user interfaces presents unique challenges for software engineers due to the unpredictable nature of human behavior and the need for flexibility in design. While software engineering principles prioritize efficiency and maintainability, user interfaces must prioritize ease of use and user satisfaction, often requiring iterative design and adaptation. These conflicting priorities create a gap between user-centered design and traditional software engineering approaches.
Key concept: The ‘hostile beast’ refers to the early computers that were difficult to use and required specialized knowledge. This highlights the initial challenges in human-computer interaction and the need for user-friendly interfaces.
2. Who Are All These People?
The field of Human-Computer Interaction (HCI) is diverse, comprised of various groups with different approaches. While this diversity brings a wide range of perspectives, it also creates a lack of cohesion and a neglect of core software engineering principles. This diversity often leads to user interfaces that are innovative but lack robustness and maintainability.
Key concept: The different groups in HCI research, from Technological Experimenters to AI Visionaries, each bring different perspectives and methodologies but often lack a shared understanding of software engineering principles. The lack of software engineering awareness within the HCI community poses a significant challenge to building robust and maintainable user interfaces.
3. Stopwatches, Videotapes, and Human Nature
While the scientific approach of controlled experiments offers valuable insights and can help validate (or invalidate) theories about user interfaces, its practical application is limited. The difficulty in obtaining statistically significant results, the oversimplification of user models, and the potential for misinterpreting results pose challenges. Additionally, the ‘escape’ of experimental software into the real world can lead to the proliferation of unreliable and unmaintainable user interfaces.
Key concept: “Science is simply common sense at its best—that is, rigidly accurate in observation, and merciless to fallacy in logic.” (T.H. Huxley). This quote highlights the importance of rigorous experimentation and logical reasoning in HCI, emphasizing the need for a scientific approach to understanding user behavior and interface design.
4. That Reminds Me of the Time…
Anecdotes, while unscientific, offer valuable practical lessons in software development, particularly for user interfaces. They capture the unexpected consequences and hidden complexities that arise when software interacts with humans in the real world. These stories serve as a rich source of practical wisdom and highlight the importance of considering the human element in software design.
Key concept: Anecdotes, like the story of the library automation system, serve as valuable lessons in software development, particularly in highlighting the unexpected consequences of seemingly small changes. These stories, while unscientific, offer practical wisdom and insights that are often missing from formal education.
5. The Quest for the Perfect Line Editor
Introducing new technologies, even those with clear advantages, faces resistance. Practicality concerns, user inertia, and the need to convince people of the value proposition are major hurdles. User interfaces, in particular, are susceptible to this resistance, as people are often reluctant to change their established workflows and learn new tools. The story of the line editor demonstrates this resistance to change.
Key concept: The evolution of the line editor to the screen editor demonstrates how new technologies face resistance due to practicality concerns and user inertia. Despite obvious improvements, new technologies must overcome these hurdles to gain acceptance, emphasizing the importance of addressing both technical feasibility and user psychology in design.
6. The Men in Suits
Non-technical stakeholders, often referred to as “the men in suits” (lawyers and executives), play a significant role in shaping software, particularly user interfaces. Their decisions, driven by legal, business, or personal considerations, can positively or negatively influence the design process. Issues such as software patents, licensing agreements, compatibility requirements, and arbitrary decisions can have a dramatic impact on user interface quality.
Key concept: “The men in suits” represent lawyers and executives who, driven by legal and business considerations, can influence software development in ways that may not align with user-centered design. Their decisions, often driven by profit or risk aversion, can stifle innovation and lead to compromises in user interface quality.
7. Information Wants to Be Free
The concept of software ownership and intellectual property creates a tension between the desire for freely accessible information and the economic realities of the software industry. This tension is reflected in the rise of the ‘hacker’ subculture and movements like ‘shareware’ and the Free Software Foundation, which challenge the traditional notion of software ownership and advocate for open access to software and information.
Key concept: “Information wants to be free” (Stewart Brand) is the rallying cry of software anarchists who believe that software ownership is a flawed concept. This philosophy, while not always practical, highlights the tension between the desire to create freely accessible software and the economic realities of the software industry.
8. Never Underestimate Your Users
Never underestimate your users’ intelligence, but recognize their limited patience for learning complex systems. User interfaces should be designed to accommodate users with varying levels of expertise, offering simplicity for novices while retaining power and flexibility for expert users. Assuming users are ‘dumb’ can lead to condescending and ultimately ineffective designs.
Key concept: Never underestimate your users; they are likely more intelligent than you assume but less willing to invest time in learning complex systems. Design for a clever, sophisticated, but impatient user. Catering to novices without sacrificing features for expert users is crucial for broader adoption.
9. Pretend That Small Is Beautiful, but Don’t Believe It
Strive for simplicity in your interface, but don’t sacrifice power and flexibility. Complexity should be hidden, progressively revealed as the user becomes more expert. The appearance of simplicity is often more challenging to achieve than actual simplicity, but is essential for attracting and retaining users.
Key concept: While simplicity is desirable, powerful programs do not have to appear complex. The key is to hide complexity behind a simple interface, progressively revealing more advanced features as users gain experience. The example of Scribe demonstrates how a complex program can present a simple user interface.
10. Tune Defaults to the Novice
Tune the default settings of your software to the needs of the novice user. First impressions are crucial, and an overwhelming or confusing initial experience can discourage further use. Iterative testing with real novice users and refining the defaults based on their feedback is essential for creating a truly user-friendly experience.
Key concept: Tune defaults to accommodate novice users, making the initial experience as smooth and intuitive as possible. First impressions are crucial, and overwhelming users with complexity at the outset can discourage further use.
11. Don’t Neglect the Experts
While catering to novices is essential, don’t neglect the needs of expert users. Experts often drive innovation and influence purchasing decisions. By providing shortcuts, advanced features, and opportunities for customization, you can cater to the needs of experts without compromising usability for novices.
Key concept: Don’t neglect the needs of expert users; they may be a smaller audience but often influence purchasing decisions and drive innovation. Cater to experts by providing shortcuts and advanced features, without compromising usability for novices.
13. Listen to Your Users, but Ignore What They Say
While user feedback is essential, don’t blindly implement user suggestions. Users are often good at identifying problems but less adept at proposing effective solutions. Listen carefully to their complaints to understand the underlying issues, but use your own expertise and judgment to design the best solutions.
Key concept: User feedback is invaluable, but users often don’t know the best solutions to their problems. Listen to their complaints to identify underlying issues, but don’t blindly implement their suggested solutions.
12. Your Program Stinks, and So Do You
Accept that your program is imperfect and will eventually be replaced. This acceptance is crucial for maintaining mental health in the face of constant criticism and the pressure to achieve perfection. View your software as a constantly evolving work in progress, and embrace the iterative nature of software development.
Key concept: Recognize the inherent imperfection of software and avoid striving for unattainable perfection. Iterate, learn from mistakes, and accept that your code will eventually be replaced. Manage your psychology to handle this reality.
14. Lie to Your Managers
Sometimes it’s necessary to ‘lie’ to your managers, particularly when their directives, based on non-technical considerations, threaten the quality of the user interface. Wrongheaded solutions must be resisted, even through deception, to ensure that the best possible user interface is ultimately produced.
Key concept: Don’t be afraid to ‘lie’ to your manager about the status or design of your project, especially if it buys you the time or freedom to explore better solutions. Sometimes, deception is necessary to protect your project from well-intentioned but ultimately harmful interference.
15. Cut Corners Proudly
Cut corners strategically during prototyping, focusing on speed and functionality over robustness and completeness. This allows for faster iteration and user feedback. Document the corners you cut, as they will likely need to be revisited during the production phase.
Key concept: Cutting corners in prototyping can be beneficial, so long as those corners are documented and revisited for the final product. Focus on getting the prototype running quickly to enable user testing and feedback.
16. Remember Your Ignorance
Acknowledge your limitations and seek expert advice. User interface design often requires expertise in areas beyond traditional programming, such as writing, graphic design, and human psychology. Recognizing your own ignorance and seeking help from relevant experts is crucial for creating a high-quality user interface.
Key concept: Recognize and acknowledge your own ignorance and limitations as a programmer, particularly in user-interface design. Seek assistance from relevant experts in areas such as writing, graphic design, or human-computer interaction.
17. Dabble in Mysticism
Be open to inspiration from unexpected sources. Good ideas can come from anywhere, from users, artists, other programmers, and even from seemingly unrelated fields. Cultivate a mindset of continuous learning and be receptive to ideas that challenge your preconceived notions.
Key concept: Be open to inspiration and good ideas from unexpected sources. Adopt a mindset of continuous learning and exploration, seeking insights from various domains and perspectives.
18. Break All the Rules
Rules are meant to be broken. While guidelines and principles can be helpful, they should not be followed blindly. Ultimately, the success of a user interface depends on the designer’s judgment, creativity, and willingness to break the rules when necessary to meet the needs of the users.
Key concept: Rules and guidelines in user-interface design are not absolute. Be willing to break the rules when necessary, prioritizing the needs of your users and the overall quality of the interface over strict adherence to any single philosophy.
19. The Tools of the Trade
Leverage the tools and techniques of software engineering. While user interface development has its unique challenges, many standard software engineering practices, such as version control, coding conventions, and code reviews, remain essential for building robust and maintainable user interfaces.
Key concept: Software engineering tools and techniques, such as version control, source code management, and coding conventions, are essential for user interface development. Leverage these tools to manage complexity, promote collaboration, and ensure maintainability.
20. The Ivory Tower

Essential Questions
1. What is the central conflict addressed in “Programming as if People Mattered”?
The core problem lies in the clash between user-centered design and traditional software engineering. User interfaces prioritize ease of use and require flexibility to cater to unpredictable human behavior. Software engineering, conversely, emphasizes efficiency, reliability, and maintainability, often through rigid pre-planning and structured processes. This conflict manifests in projects producing either reliable but disliked software or user-friendly but unmaintainable software. The book explores how to navigate this conflict by adapting software engineering methodologies to accommodate the iterative and user-focused nature of interface design, thereby creating products that satisfy both user needs and engineering requirements.
2. How can software developers effectively address the unpredictable nature of user needs and preferences when designing interfaces?
Given the inherent unpredictability of human behavior and preferences, creating truly “user-friendly” software is a continuous challenge. User studies, though helpful, provide limited predictive power. Users often struggle to articulate their needs, and their feedback may not always lead to the best solutions. The book suggests iterative prototyping, user testing, and an openness to feedback as essential strategies for approaching this problem. It also emphasizes separating user interface code from core functionality to facilitate adaptation and change based on user input.
3. What role do non-technical stakeholders play in shaping software, and how can developers effectively manage their influence?
Non-technical stakeholders, like managers and lawyers, exert significant influence on software development, often without a deep understanding of user interface design. Their decisions, driven by legal, business, or personal biases, can lead to arbitrary requirements or stifle innovation. To navigate this, developers must communicate effectively, using prototypes and user feedback to demonstrate the value of user-centered design and sometimes resorting to strategic “lies” or deception to protect their projects from well-intentioned but misguided interference.
4. How can software effectively accommodate the needs of both novice and expert users?
The book emphasizes that user interfaces must cater to both novice and expert users. Novices require simple defaults and intuitive designs to avoid intimidation and promote quick learning. Experts, conversely, demand power, flexibility, and shortcuts to maximize efficiency. Successfully accommodating both groups necessitates a layered approach to interface design, offering simplified views for novices while providing access to more advanced features and customization options for experts. Striking this balance is crucial for broader software adoption and long-term usability.
5. What is the ‘Golden Path’ or ideal approach proposed for human-oriented software engineering?
The book proposes a framework for human-oriented software engineering, which blends traditional engineering principles with user-centered design practices.

Key Takeaways
1. Prioritize iterative prototyping and user feedback.
Users are central to the success of any software, especially user interfaces. Their needs and preferences are often unpredictable and poorly understood by developers. Iterative prototyping, user testing, and continuous feedback are essential for uncovering these needs and adapting the software accordingly. This iterative process allows for flexibility and responsiveness to user input, leading to a more user-centered and ultimately more successful product.
Practical Application:
An AI product engineer developing a chatbot should prioritize user testing and feedback throughout the development process. Initial prototypes might focus on core functionality, but subsequent iterations should incorporate user feedback regarding conversation flow, response accuracy, and overall user experience. By prioritizing user needs and preferences, the chatbot can be refined to be both effective and engaging.
2. Embrace simplicity without sacrificing power.
Software, especially that involving user interfaces, should strive for simplicity without sacrificing power and flexibility. Complexity can intimidate and overwhelm users, particularly novices. Hiding complexity behind a simple, intuitive interface, while progressively revealing advanced features as needed, allows users to gradually learn and master the system at their own pace.
Practical Application:
When designing a new feature for an AI-powered image editing tool, avoid overwhelming users with numerous complex options. Instead, present a simplified interface with essential tools readily available. More advanced features and customization options can be progressively revealed through tutorials, tooltips, or expandable menus as users become more familiar with the system.
3. Cater to both novice and expert users.
User interfaces must cater to both novice and expert users. Novices require simple defaults and intuitive navigation to avoid frustration, while experts demand power, flexibility, and efficiency. Balancing these needs requires a multi-layered approach to interface design, with progressively revealed complexity and customization options. Understanding the different needs and expectations of these user groups is crucial for designing truly effective interfaces.
Practical Application:
An AI product manager launching a new recommendation engine should gather feedback from both novice and expert users. Novice users might be surveyed about the ease of understanding recommendations, while expert users might be asked about the engine’s ability to cater to specific preferences and edge cases. This approach ensures that the product meets the diverse needs of its target audience.
4. Leverage software engineering best practices.
Software engineering best practices, while often overlooked in UI design, are essential for building robust and maintainable interfaces. Version control, in particular, is crucial for tracking changes, managing revisions, and facilitating collaboration among developers, especially during iterative prototyping. It enables developers to experiment freely with different designs, knowing that they can always revert to a previous version if needed. Similarly, source code management, coding conventions, and regular code reviews can enhance code quality, maintainability, and long-term stability.
Practical Application:
An AI development team can use version control to track changes made during the development of a new machine learning model. Each iteration of the model, with different parameters or training data, can be tagged with a unique version number. This allows the team to revert to previous versions if needed, compare performance across versions, and track the evolution of the model over time. When designing the UI for an ML model, the specific version of the model should be visible to the user and in any bug reports.

Comparative Analysis
While “Programming as if People Mattered” predates many contemporary works on UX and HCI, its core message resonates with later books like Steve Krug’s “Don’t Make Me Think” and Jakob Nielsen’s “Usability Engineering.” All three emphasize user-centered design and the importance of simplicity and intuitiveness. However, Borenstein’s book delves deeper into the organizational and cultural challenges of integrating user-centered design into the software development process. Unlike Krug’s focus on web usability, Borenstein addresses broader software development. Nielsen’s book, while more technically oriented, complements Borenstein’s by offering practical guidelines and heuristics for usability evaluation. A significant difference is Borenstein’s emphasis on the limitations of traditional software engineering methodologies and the need for a more flexible, iterative approach to UI development, a concept less explicitly addressed in other works. His book offers a valuable historical perspective on the evolution of HCI and the ongoing tension between user needs and engineering constraints.
Reflection
Borenstein’s book offers a compelling narrative about the challenges of user interface design, but it’s important to view it in its historical context. The book was written in 1991, when software development practices and the tools available were considerably different from today’s. The rise of agile methodologies, rapid prototyping tools, and user-centered design frameworks have addressed some of the challenges he describes. However, his core arguments about user unpredictability, the tension between UI design and engineering, and the importance of iterative development remain relevant. While his anecdotes are entertaining and insightful, they are not empirical evidence. His emphasis on “lying to managers” is provocative and context-dependent; it may be less applicable in today’s more collaborative and transparent work environments. The book’s strengths lie in its clear articulation of the challenges faced by UI developers, its emphasis on user psychology, and its practical advice for navigating the often-political landscape of software development. Its weakness is its reliance on anecdotal evidence and its lack of detailed technical solutions. Overall, it remains a valuable read for anyone involved in software development, offering historical perspective and timeless insights into the human element of software design.
