Hello everyone, and welcome to my blog entry for this week!For this week’s self-directed professional development, I explored the topic of Software Design Methodologies and Agile Practices. I used several online resources, including tutorials from Atlassian Agile Coach and readings from GeeksforGeeks. Even though the focus was on understanding Agile methodologies, I found that many of the ideas connected directly to our discussions in class about the software development life cycle (SDLC) and software design principles.
Summary of the Resource
Software design methodologies provide structured approaches to building and maintaining software systems. They define how development teams plan, design, implement, test, and deliver software. Traditional methodologies like the Waterfall Model, V-Model, and Spiral Model follow a sequential or plan-driven approach — where each stage must be completed before the next begins. These models emphasize documentation, predictability, and control.
On the other hand, Agile methodologies such as Scrum, Kanban, and Extreme Programming (XP) prioritize adaptability, collaboration, and continuous feedback. Agile breaks development into small iterations or “sprints,” allowing teams to quickly adjust to changes in requirements or user needs. Instead of rigidly following a plan, Agile embraces flexibility — delivering functional software early and improving it continuously.
The Agile Manifesto summarizes this philosophy in four values:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
Why I Selected This Resource
I chose to focus on Agile methodologies because I wanted to understand how modern development teams manage complexity in real-world projects. We often hear about Agile in professional settings, but I wanted to explore why it has become so widely adopted. After learning about structured models like Waterfall, I was curious to see how Agile differs in terms of flexibility, teamwork, and iterative design.
This topic also connects closely to our class discussions on object-oriented design and project management, where adaptability and maintainability are key. Understanding these methodologies helps bridge the gap between theoretical design principles and practical implementation in team environments.
Personal Reflections: What I Learned and Connections to Class
Exploring Agile helped me see how methodology shapes not only the process but also the culture of software development. Here are a few takeaways that stood out to me:
- Iteration mirrors refinement in design. Just like UML diagrams evolve as designs improve, Agile projects evolve through sprint cycles that incorporate feedback.
- Communication is central. In Agile, daily stand-ups and retrospectives ensure the entire team stays aligned, similar to how collaboration in object-oriented design ensures consistent architecture.
- Adaptability is a strength, not a weakness. While traditional models aim for stability, Agile embraces change — which is essential when building modern, user-driven applications.
In class, we often focus on designing systems that can evolve. Agile reinforces that same mindset at the project management level software design should anticipate growth, not resist it.
Application to Future Practice
Moving forward, I plan to apply Agile thinking to my future software projects, especially in group work or larger systems. Instead of trying to perfect a design from the start, I’ll focus on building incrementally, testing continuously, and welcoming feedback early in the process.
For example, in future programming projects, I could organize development into short milestones, use version control branches to represent sprints, and hold mini “retrospectives” after each stage. These habits will not only improve collaboration but also help me develop adaptable, high-quality code.

This exploration helped me connect the structured approaches of traditional methodologies with the flexibility and innovation of Agile. It reinforced that software design isn’t just about code — it’s about creating systems and processes that can evolve as technology and user needs change.
