Unrelated: Refactoring A Must-Have Skill for Any Programmer

When restructuring existing code, refactoring maintains its external behavior. Methods should facilitate reuse and modification, just like classes. Breaking down code into smaller methods results in better design and easier rearrangement of behavior. Refactoring code can even clarify design when the ultimate goal is unclear.

Each class must be responsible for achieving maintainable and flexible object-oriented software. Object-oriented programming languages model reality, but objects become dependent when they know another class. To avoid coupling objects and the need for a complete rewrite in the future, dependencies must be injected.

Ruby makes it easy to differentiate between data structure and meaning by wrapping instance variables using methods or the Struct class. It's crucial to ensure that methods have a single responsibility, which involves summarizing their duties in a single sentence and asking questions about their job.

Data should be hidden from oneself to protect the code from unexpected changes. Data often have behavior that may not yet be known, so it's best to send messages to access variables instead of thinking of them as data. Keeping this knowledge in one place is essential. Refactoring improves the internal structure of code while preserving its external behavior, promoting flexibility, and simplifying future changes. It prioritizes simplicity, readability, and changeability over complexity, and code manageability is crucial when making changes.

Off Topic: How Impact Mapping Transforms Software Projects into Business Triumphs

When working on a project, the main focus should be contributing to business outcomes rather than just creating software. Impact mapping is a helpful technique that goes beyond a formal requirements document to determine what impacts the business is trying to make. This includes increasing sales, market share, or customer engagement. By working closely with the business, you can better understand its goals and create a shared vision for the product. An impact map helps identify the business's assumptions and goals, and your technical expertise can suggest alternatives they may have yet to consider. Impact mapping helps to communicate assumptions and align team activities with business objectives.
