My Process of Designing and Architecting Software

Summary

In this video, the speaker shares a unique approach to designing software and writing books, inspired by the 'write to think' method. By blocking out 2-3 hours of uninterrupted writing time, using simple, distraction-free tools, and iterating through detailed workflows and design documents, the speaker creates clear, actionable plans for both software and book creation. This method emphasizes simplicity, collaboration with stakeholders, and disciplined reflection to clarify ideas. The speaker outlines a structured process for extracting the minimum viable product and crafting technical documents, followed by simple diagrams to finalize the design.

Takeaways

• 😀 Writing to think is a core principle in both software design and writing books. You don’t think to write; you write to think.
• 📅 Block off 2-3 hours of uninterrupted time to focus deeply on writing and problem-solving without distractions like emails or meetings.
• 📝 Use clutter-free, full-screen writing apps like WriteMonkey or FocusWriter to avoid distractions and promote focus.
• ❓ Writing down workflows helps generate questions and clarifications from stakeholders, which improves the design process.
• 🔄 Collaborate with stakeholders by compiling and discussing questions that arise during the workflow drafting phase to ensure alignment.
• 🔧 The minimum viable product (MVP) is a crucial step. Start by defining the MVP before expanding to the full vision of the software.
• 🖥️ A design overview document is written after defining the MVP. It provides a technical representation of the workflow using detailed terms like reverse proxies, databases, and server-side technologies.
• ⚙️ Break down the system into components and describe each one in detail, focusing on how it interacts with other parts of the system and its technical specifications.
• 📊 Diagrams should be kept simple and serve to visualize how the components interact, not to overcomplicate with technical jargon or UML diagrams.
• 🔄 Iterate and refine your designs by continually writing, questioning, and discussing with your team to improve the system’s architecture and functionality.
• 💡 The writing process is not just for final products but for thinking through complex problems and articulating solutions that lead to a better-designed product.

Q & A

What is the core principle behind Hussain's approach to software design and writing?

The core principle is that writing helps you think. Rather than thinking to write, Hussain suggests just writing to discover and refine ideas, which he applies both to writing books and designing software.

How does Hussain recommend organizing time for writing and software design?

Hussain recommends blocking off two to three hours of uninterrupted time for focused work. During this time, there should be no meetings, emails, or notifications to minimize distractions.

What tools does Hussain use to maintain a clutter-free writing environment?

Hussain uses WriteMonkey for Windows and FocusWriter for macOS. Both tools offer a distraction-free environment with features like full-screen dark mode to help maintain focus on the writing task.

How does writing a workflow help in the software design process?

Writing the workflow in detail helps clarify how the software will be used from start to finish. It also raises important questions about the project, which need to be clarified with stakeholders, ensuring the design is aligned with the users' needs.

Why is it important to state the obvious when writing the software workflow?

Stating the obvious allows ideas to flow freely and makes the design process more transparent. It ensures that even the smallest details are considered, which may raise valuable questions or insights from stakeholders.

How does Hussain approach stakeholder feedback in the workflow phase?

Hussain compiles questions from the workflow draft and meets with stakeholders to gather their feedback and clarify any ambiguities. This helps finalize the workflow and align the project with the stakeholders' expectations.

What is the role of the Minimum Viable Product (MVP) in Hussain's design process?

The MVP is extracted from the finalized workflow. It defines the minimal set of features needed for the first release. The goal is to ship a functional product quickly and iteratively improve it over time.

What details are included in the 'Design Overview' phase?

The Design Overview phase includes a technical description of how the software will be implemented, including user interactions, technical specifications like reverse proxies and databases, and how components of the system will communicate with each other.

Why does Hussain avoid using complex diagramming languages like UML?

Hussain prefers simple diagrams with boxes, arrows, and text because they are more intuitive and less complex than formal diagramming languages like UML. He believes these simple diagrams are more effective in conveying the system's architecture.

How does Hussain ensure the design stays aligned with the original workflow?

Throughout the design process, Hussain emphasizes referencing the original workflow to ensure that the technical specifications remain aligned with the user-facing requirements. Any deviation is checked to ensure it still supports the user's needs.

What role do component-level documents play in the design process?

Component-level documents describe each part of the system in detail, including how each component works, what it interfaces with, and its technical specifications. These documents help to ensure that all aspects of the system are thoroughly considered before finalizing the design.

What is the significance of iteration and feedback in Hussain's design approach?

Iteration and feedback are critical in Hussain's approach. After each phase, such as writing the workflow or design overview, Hussain schedules reviews with the team to refine the design. This ensures that the final product meets the technical and user requirements while allowing for continuous improvement.
