What are the problems that develop in software systems over time? How does agile design overcome these problems?

Agile Design: Preventing Software Decay

Problems Developing in Software Systems Over Time

  • Increasing Complexity: Features added without a holistic view create tangled code.
  • Technical Debt Accumulation: Quick fixes and shortcuts lead to unstable and difficult-to-maintain code.
  • Reduced Maintainability: Understanding and modifying existing code becomes increasingly challenging.
  • Feature Creep: Uncontrolled addition of features beyond initial scope, bloating the system.
  • Lack of User Focus: Initial design becomes outdated, losing alignment with user needs and expectations.
  • Security Vulnerabilities: Over time, security flaws may emerge in older codebases.
  • Integration Difficulties: Integrating new features or systems becomes more complex with age.
  • Performance Degradation: Systems may slow down as more features and data are added.

How Agile Design Overcomes These Problems

  • Iterative Development: Breaking down projects into smaller, manageable iterations allows for continuous feedback and adaptation.
  • User-Centric Design: UI/UX is integrated throughout the process, ensuring continuous user feedback.
  • Continuous Testing and Integration: Frequent testing and integration prevent large-scale failures and identifies issues early.
  • Prioritization and Scope Management: Agile methodologies emphasize prioritizing features and managing scope to prevent feature creep.
  • Adaptive Planning: Agile plans are flexible and allow for changes in requirements and priorities based on feedback.
  • Refactoring and Code Quality: Regular refactoring maintains code quality, prevents technical debt buildup, and enhances maintainability.
  • Collaboration and Communication: Agile fosters close collaboration between developers, designers, and stakeholders, improving communication.
  • Continuous Improvement: Regular retrospectives analyze past iterations to identify areas for improvement and prevent future issues.

Explain uniquely decodable code with example.

Uniquely Decodable Codes: A Deep Dive into Data Compression What is a Uniquely Decodable Code? A uniquely decodable code ensures that any encoded message can be decoded into only one possible original message. Ambiguity in decoding is eliminated. This is crucial for reliable data transmission and storage. The Importance of Unique Decodability in Data Compression Avoids information loss during decompression. Enables lossless data compression techniques. Guarantees data integrity. Example: A Uniquely Decodable Code Consider a code where: - A = 0 - B = 10 - C = 11 The encoded string "01011" can only be decoded as "ABCB". No other interpretation is possible. Example: A Non-Uniquely Decodable Code Consider a code where: - A = 0 - B = 01 - C = 011 The encoded string "011" could be interpreted as "B" or "C". This is not uniquely decodable, leading to ambiguity. Prefix-Free Codes (A type of...

Differentiate between Bottom-up versus Top-down Design.

Bottom-Up vs. Top-Down Design: A Developer's Guide Key Points: Bottom-up design: Starts with individual components and integrates them into a larger system. Top-down design: Begins with a high-level overview and breaks it down into smaller modules. Key Difference: Bottom-up focuses on component-level detail first, while top-down prioritizes overall architecture and functionality before delving into specifics. **Understanding Bottom-Up and Top-Down Design Approaches** Feature Bottom-Up Design Top-Down Design Starting Point Individual components, modules, or features Overall system architecture and high-level requirements Process Develop individual parts, then integrate; iterative refinement Define overall structure, break into smaller modules, then develop each Suitability Reusable components, complex systems ...
