Understanding Agile Methodology
What is Agile Project Management?
Agile is a project management that is especially incorporated within software development processes. Agile project management methodology was created by Ken Schwaber and Jeff Sutherland during the 1970s. Agile methodology was an answer to the need of more flexible and fast-paced projects that truly answer the market’s needs and the fast-pace.
Agile methodology emphasizes flexibility, collaboration, and customer-centricity. Agile project management allows teams to not follow a rigid, linear plan; instead they are able to adapt to changes quickly and efficiently. Agile methodology addresses projects within the scope of 2 or 4 weeks of sprint cycles. These sprint cycles allow teams to collaborate and adapt to the changes during the development phases of the projects.
Understanding various project management approaches is crucial for tailoring solutions that best fit particular situations. This methodology allows teams to face any unexpected difficulties easily. The core characteristic of agile methodology is iterative development and flexibility. Iterative development processes allow collaboration among different teams across different situations.
Principles of Agile Methodology
-
Customer Satisfaction: Agile methodology aims to answer customer needs and expectations with a faster pace in shorter timescales.
-
Embrace Change: Agile processes’s core difference is that it is adaptable and flexible to any and all kinds of unexpected changes even at a later point through the project.
-
Frequent Delivery: Agile methodology allows teams to deliver software projects faster and more frequently.
-
Collaboration: Agile requires stakeholders and developers to collaborate throughout the project.
-
Motivated Individuals: The fast-pace, flexibility, and collaboration created by Agile motivates teams around the project.

Agile vs. Scrum
What is Scrum?
Scrum is a specific framework within the broader Agile methodology that is much more focused to the specific stages of development. Agile is the overall umbrella methodology whereas Scrum is specific details regarding the sprint phases. The sprint stages in the Agile methodology usually lasts 2-4 weeks. Scrum methodology specifically focuses on organizing these stages, often led by a project manager who ensures that the team meets defined goals, budgets, and timelines.
Comparing Agile and Scrum
Agile is the umbrella philosophy and a set of principles about project management and software development that focuses on adaptability, fşexibility, and user-centric approaches. Scrum is the concrete implementation of Agile principles during the development stages. Scrum offers methods such as Daily Stand-ups and Sprint Reviews that incorporate Agile principles into the practice. You can see the detailed differences between Agile and Scrum shown in the table below:

Scrum is a concrete framework within the broader Agile methodology. Agile is a flexible umbrella philosophy for project management. Scrum is the specific and structured approach with defined roles and requirements throughout the development process.
Agile vs. Waterfall
What is Waterfall?
Waterfall is the traditional project management approach. Waterfall methodology is rigid and sequential, following a defined project life cycle that includes stages from initiation to monitoring and controlling. The waterfall methodology traditionally follows 5 stages: gathering, design, implementation, testing, and deployment. This methodology requires each phase to be completed before moving on to the next and is directional unlike the cyclical and flexible approach of Agile. Since the stages are followed step-by-step, changes and adaptations are difficult to do during Waterfall methodologies.

Key Differences Between Agile and Waterfall
Agile and Waterfall are fundamentally different in their approach to project management. Agile is flexible, adaptive, iterative, and cyclical with its sprints. Agile allows teams to adapt and revise the project at almost every stage. However, Waterfall is linear and structured. There are distinct phases in Waterfall systems that make it difficult to adapt to changes.
In both Agile and Waterfall methodologies, defining the project scope is crucial. It helps in structuring the project team, setting realistic boundaries to prevent scope creep, and guiding project planning to ensure that objectives and deliverables are clearly outlined and understood by all stakeholders.

Choosing Between Agile and Waterfall for Your Project Life Cycle
You need to clearly analyze the nature and requirements of the project you are working on before choosing between Agile or Waterfall methodologies. If your project is dynamic and requires flexibility, it would be best to use Agile methodology. Similarly you should implement Agile, if your project changes depending on frequent customer feedback. However, if you are working on a project with well-defined and stable requirements, you can benefit from Waterfall methodologies greatly since it offers a clear timeline and structure.
Waterfall is a traditional and linear project management approach. Waterfall is rigid and sequential, while Agile is flexible and allows for adaptation. Choosing between them depends on whether the project requires flexibility and frequent changes (Agile) or has well-defined, stable requirements (Waterfall).
