Part 1. What is Agile
Before knowing the differences between agile and waterfall, understand their definition first. So, keep reading to learn more.
Agile is an iterative and flexible form of project management. It emphasizes adaptability that embraces changes of direction even late in the procedure. Agile is about collaboration, making customers satisfied, and continuous refinement. Apart from that, it breaks down big projects into small components. With the changing needs of customers, agile flexibility is becoming essential. Thus, it is all about getting better results.
Main Uses
◆ It is usually used in software development projects.
◆ Teams can apply it to various project types. And so, it allows adaptability and continuous improvement.
◆ Teams or organizations can use it to create or enhance products. It supports iterative development based on customer needs.
PROS
- Agile allows changes and adjustments throughout the project.
- It focuses more on customer feedback to ensure the product meets user needs.
- Agile encourages close collaboration among team members. So it enhances communication and teamwork.
- It has better visibility or accountability.
CONS
- Its flexibility can sometimes lead to uncertainty.
- It often prioritizes working software over extensive documentation.
- It is not ideal for projects with well-defined and unchanging requirements.
Part 2. What is Waterfall
The waterfall is a traditional and linear project management approach. It is where you need to complete the task in a step-by-step sequence. Its rigid structure and predetermined phases usually characterize it. Oftentimes, it is effective for straightforward projects that need minimal adaptation. Hence, it may not be suitable for more complex initiatives.
Main Uses
◆ It is good for projects with clear and stable plans. It works well when you know what exactly needs to be done.
◆ It is a step-by-step process. With it, you do step one at a time, and you can’t proceed without finishing the previous step.
◆ One of the uses of the waterfall is for smaller and straightforward projects. Here, you don’t expect tons of changes along the way.
PROS
- It provides a solid plan for the project from start to finish.
- It uses a clear and structured approach.
- Easy to track progress and spot potential risks.
- It has a comprehensive documentation of its results and processes.
- Suitable for projects that are unlikely to change throughout the project.
CONS
- It is not helpful for projects with evolving requirements.
- It is not an ideal model for complex and large-size projects.
- Projects may take longer to complete. Each phase must finish before the next begins.
Part 3. Differences Between Agile vs. Waterfall
Here are 6 vital agile vs. waterfall project management differences you should know:
| Aspect | Agile | Waterfall |
| Approach | Agile is a flexible and adaptable approach. It allows changes throughout the project | Waterfall is a sequential and rigid approach. It has predefined stages and a linear progression. |
| Delivery | Agile gets things done fast with shorter project cycles. It gives you something that works after each small step. | In Waterfall, you have to finish everything before anything is ready to use. |
| Documentation | Agile emphasizes teamwork and self-organizing teams rather than extensive documentation. Yet some documentation is maintained. | On the other hand, a waterfall requires extensive documentation. Each stage and project progress must be defined. |
| Roles Delegation | In agile, team members should collaborate on different parts of the project. Thus, it leads to a more self-organizing structure. | In contrast, waterfall assigns roles to its project team members. Each member has specific responsibilities and duties. |
| Quality Control | Agile prioritizes testing and quality control. It allows for early detection and resolution of problems. | Waterfall, in contrast, performs quality control in the testing phase. As a result, it leads to late issue discovery. |
| Planning Process | In agile, planning is not done in advance. All the planning processes of agile teams are ongoing since they work on an active sprint. | In a waterfall, detailed planning is essential since teams do it once. It allows the team to achieve the goals they set for their project. Plus, they do not make any modifications to the scope and requirements of the project. |
