Agile vs Waterfall Advantages of the Agile Methodology
Project Size Decides Method
Agile – LargerAgile excels for larger projects. As grand-scale projects break down intosmaller areas, there is greater attention then given to the quality of thefinal product.Waterfall – SmallerWaterfall suits for smaller projects. The structured process is designed forsimple-to-understand projects, as it takes instructions from the onset,engaging until the end.
Introduction to Project Management Methodologies
Software development has evolved considerably over the past decade. Businesseshave started to build their technology on solid and scalable platforms andprogramming languages with the aim of making the solution extensible forfuture additions of features and capabilities.While the number of frameworks, platforms and programming languages have grownseveral folds, there is an equally important evolution that happened in theway software development initiatives are managed.Project management has diversified into a comprehensive practice that aims notonly to deliver software on time, but also to ensure zero defects, provideaccurate forecasting for stakeholders and enable seamless visibility andtransparency between dependent teams in a project.While traditional project management focused on the waterfall developmentprinciple, today successful technology projects have transitioned into agileand scrum-based project management methodologies to deliver more value for theinvested effort.
Agile vs Waterfall : Difference between Project management Methodologies
Before we proceed further, you need to understand the difference between Agileand Scrum. In simple terms, agile is an implementation principle or philosophythat encompasses a set of practices to complete a development project fromstart to finish.Scrum is one of these practices or in broader terms, a platform to implementthis agile methodology. A scrum is an agile approach while agile does notalways imply you are using Scrum. Kanban is an alternative agile platform youcan use instead of Scrum.So, since the difference is cleared between that, you will have the obviousquestion:-> Which project management method should I choose for software development in my business?Let’s have a brief look at how the most popular methods i.e. Waterfall andAgile fare in modern software development initiatives. The comparison of Agilevs Waterfall will help you make a decision suitable for your unique softwaredevelopment challenges.* * *The waterfall method is a linear and sequential way of building softwarewherein every stage of development happens in a sequence starting fromrequirement analysis to design, coding, testing, implementation andmaintenance.Agile is an iterative and modular form of software development wherein asingle software product or project is broken down into functional componentsand each component is assigned to a person or team and then the development ofthese components are tracked in time-bound phases called sprints.In each sprint, there will be an itemized set of deliverables to be done inthe sprint duration. At the end of each sprint, there will be a retrospectiveanalysis on what went good and what did not in that sprint and lessons learnedwill be used for re-organizing or prioritizing tasks in future sprints.
What are the Project Management Methodologies?
Methodologies provide frameworks to help you to organize your project’sinitiating, planning, executing, monitoring and closing processes. From thisaspect, there are lots of methodologies still in use in the world of projectmanagement. Some of them provide traditional solutions, some others providemore innovative frameworks. Waterfall, Agile, Lean, Extreme Programming, SixSigma are some of the most common ones. Although they have the same goal:carrying out the project to successful completion, their principles arevarious. We recommend you to read this article regarding the projectmanagement methodologies if you don’t know the key differences between them.In this article, we are going to focus on the two methodologies which areagile and waterfall.
Agile vs Waterfall – Advantages of the Agile Methodology
* Since the agile projects are client-focused, the agile makes sure that the client is involved in every stage continuously. * The team members demonstrate better performance. Because coordination and collaboration among team members are key for the success in agile projects. * The agile project management methodology ensures that the quality of the product is maintained. * Risks are minimized because the process is based on incremental progress. * It is applicable to large and complex projects.
Agile vs Waterfall – Limitations of Agile Methodology
* It can not be effective in smaller projects. * If the client is not clear about the final product, the project can easily go off track. * The Agile methodology requires a senior programmer to take important decisions during the meeting. * It is costly considering other methodologies.For better understanding the Agile vs Waterfall concept, let’s talk about theWaterfall Project Management Methodology.
What is the Waterfall Methodology?
Waterfall is a liner sequential model in which the project work is completedsequentially in each phases. This means the predecessor phase ends and thesuccessor phase starts just after. Waterfall is a straightforward methodologyfor project management which helps to perform progress measurement easily. Thetesting phase takes place at the end of the development. The client orstakeholders are not too much involved compared with the agile methodology.
Agile vs Waterfall – Advantages of Waterfall Methodology
* Each sequential phase has specific needs and deliverables. This makes easy to plan and manage. * It suits best to the projects with well-defined scope and requirements. * It suits best to the smaller projects. * It speeds up the deliveries of the project * Everything is well documented
What are the Similarities and Differences Between Agile and Waterfall
Methodologies? Here below you can understand the key differences by checking the Agile vsWaterfall comparison table.
Agile vs Waterfall Comparison Table
Agile Methodology | Waterfall Methodology —|— Divides the project development lifecycle into sprints. | Divides the softwaredevelopment process into distinct phases. Follows an incremental approach | Follows a linear sequential approach It s a flexible methodology | It is a rigid structural methodology Agile can be considered as a collection of various projects | It will be doneas one single project. It is easy to make changes because of its flexibility | It is difficult tomake changes Test plan is discussed after the completion of each sprint | Test plan isreviewed during the testing phase Project requirements are subject to change | The waterfall is suitable forprojects with definite requirements. Changes are not easy. Agile vs Waterfall Agile is a customer-focused methodology. Changes on the product is as per thecustomer’s requirements | Waterfall methodology relies on definite projectrequirements Fixed project budget is not suitable for the implementation of agilemethodology. There may be some flexibility. | Since all the requirements andthe project scope is defined well, the project budget does not change toomuch. High communication and collaboration among the team members | Lowcommunication and collaboration among the team members Products owner and the project team collects the requirements every day. | Allthe requirements are defined before to start the project. Follows an iterative development approach so that planning, development andtesting phases may appear more than once. | Phases are linear and sequential.Once a phase is completed, the next phase starts. Testing is performed in conjunction with software development. | Testing phasecomes once the build phase is completed.
Introduction to Agile Methodology
Software development is at its peak today with every major player in the techdomain wanting a piece of the pie.Most of these major corporations seem to have been attracted to a particularmethodology of choice for their needs. This methodology, known as agile is atthe crux of the software development process today.Agile hasn’t been here forever, though it has only made its mark in the lastcouple of years.The waterfall methodology was the one that used to dominate the softwaremarket before agile kicked in. But what is so unique about agile thatdifferentiates it from every other software development methodology out there?More importantly, what is agile, anyways? Let’s find out.
Journey to a More Agile Process – From Waterfall Methodology to Agile
The waterfall methodology streamlined software development in the 90s. Itprovided a concrete developmental strategy that was widely adopted by theworld over.It functioned primarily based on the assumption of uniformity and a non-dynamic environment. It was adequate, considering most software back in the1980s didn’t evolve with time or weren’t flexible enough to incorporate newand more robust changes.However, the era of the internet brought in a new generation of dynamicframeworks that had to be adopted to keep up with the industry.It is where the waterfall methodology failed to deliver. It was so rigid inits approach that it couldn’t keep up with the ever-evolving environment. As aresult, businesses, especially small startups, began looking for ways toapproach product development.During this time, a team of highly intelligent software developers realizedthat they had come up with an entirely new approach to developing programsthan was traditionally practised via the waterfall framework.Contrary to what you’d think, not everyone in this team was from a startup.Some of them were technical geniuses in big corporations including Kent Beck,Martin Fowler, Ron Jeffries, Ken Schwaber, and Jeff Sutherland. They came upwith the agile manifesto that documented their ideas and approach to softwaredevelopment.The manifesto played a critical role in laying the foundation for the agilemethodology. It stressed extensively on the ideas on collaboration andflexibility that gave birth to a robust framework of modern softwaredevelopment.
