There are two popular methods of software development.
- Waterfall Methodologies
- Agile Methodologies
Though both the methodology is efficient and a very much similar in order to achieve their respective goals which is to achieve the path to determine the best strategy in terms of feasibility to complete certain project within a predetermined stipulated amount of time , they follow completely different way.
Waterfall Methodologies: it is the method which is being defined as the traditional process of software development. It is being used for small projects and educational project purpose. The phase it consists of is requirement, design, implementation ,testing, deployment and maintenance. It was first released in 1989. Here any stage in development phase may begin only once the previous phase is being completed
Pros of waterfall model
Due to the nature of project’s , each phase contains review process and deliverable as well it is the most simple types to operate
It is suitable for smaller projects
Both outcomes and procedure is being recorded meticulously
This project management approach is useful for dealing with dependencies
Cons of waterfall model
This methods is not applicable for big projects
If the client’s requirements is not properly defined then this process is less effective
All the phases is interdependent and difficult to travel ahead and make changes to previous stages
Due to the above reason if any major error or bugs found during the testing then it is very difficult and costly to fix it as again all the phase one after another needed to be implement.
Agile Methodologies: it is the method which ci/cd options called continuous development and continuous integration. Here the entire project is being divided into multiple pieces and then all the small pieces are being developed and integrated for a long period of time. This method helps consumers, developers, managers, and testers to communicate more effectively. The process it consists of is product overview, user story workshop, product backlog creation, sprint planning, sprint backlog creation, define scrum, sprint review,sprint burndown, product burndown, s print retrospect and repeats again. In practical all these are being maintained by tools like jira ,git lab etc.
Pros of agile model:
This method is more customer centric so customer as a stakeholder is being involved in throughout the project
This project is being developed bunch f motivated team player as a result they deliver superior results in development projects
In this method functionalities are being developed in small chunks so before integration it is being tested each time so throughout the development phase quality is being maintained
As the product is being developed in an incremental growth after completion of each task it can easily be measured the status of the project like what has and has not been accomplished. It reduce the risk of the development phase.
Cons of agile model:
For small scale project it is not viable in terms of effort and time
Here rather than professional presentation in the meeting crucial choices are being made
It is costly than traditional method
Continuous engagement is client is needed for understanding of the requirement as the requirement can be changed during the product incremental.
Key difference
| agile | waterfall |
| list of lacks are being made everyday by project manager and associates | specifications is being made by the ba at the beginning of the project |
| making any changes during the development phase is easy to implement and always welcome. | making changes is costly as it requires to follow the same procedure again to implement it |
| testing takes places throughout the project in each phase | after build setup testing is done,and coding phase is being completed |
| here it is a compilation of several outlines | here software gets developed as specific outline |
| sprints are used to break down the project into manageable pieces. | In general, the methodology gets separated into several stages. |
Conclusion
Agile works effectively for processes that involve ci/cd (continuous integration/continuous development) whereas waterfall is being used for specific task.unraveling into iterative portions enables for speedier feedback loops, permitting your service to be readily modified to reflect client preferences. It is critical to realize that there is still no one-size-fits-all solution for job management
