Waterfall Methodology

Here is the regular, safe approach for managing software development. Teammembers and managers layout all requisites up front. From that point, strictschedules are closely monitored. Before teams move to a new phase of thesequential development schedule, requisites must be met and tasks must bedone. Rather than testing changes throughout the process, teams develop anear-complete product and push it to user testing at a predefined date.Popular products: LiquidPlanner, Microsoft Project, Smartsheet and Basecamp.

The Waterfall Methodology

Waterfall is a linear approach to software development. In this methodology,the sequence of events is something like: 1. Gather and document requirements 2. Design 3. Code and unit test 4. Perform system testing 5. Perform user acceptance testing (UAT) 6. Fix any issues 7. Deliver the finished productIn a true Waterfall development project, each of these represents a distinctstage of software development, and each stage generally finishes before thenext one can begin. There is also typically a stage gate between each; forexample, requirements must be reviewed and approved by the customer beforedesign can begin.There are good things and bad about the Waterfall approach. On the positiveside: * Developers and customers agree on what will be delivered early in the development lifecycle. This makes planning and designing more straightforward. * Progress is more easily measured, as the full scope of the work is known in advance. * Throughout the development effort, it’s possible for various members of the team to be involved or to continue with other work, depending on the active phase of the project. For example, business analysts can learn about and document what needs to be done, while the developers are working on other projects. Testers can prepare test scripts from requirements documentation while coding is underway. * Except for reviews, approvals, status meetings, etc., a customer presence is not strictly required after the requirements phase. * Because design is completed early in the development lifecycle, this approach lends itself to projects where multiple software components must be designed (sometimes in parallel) for integration with external systems. * Finally, the software can be designed completely and more carefully, based upon a more complete understanding of all software deliverables. This provides a better software design with less likelihood of the “piecemeal effect,” a development phenomenon that can occur as pieces of code are defined and subsequently added to an application where they may or may not fit well.Here are some issues we have encountered using a pure Waterfall approach: * One area which almost always falls short is the effectiveness of requirements. Gathering and documenting requirements in a way that is meaningful to a customer is often the most difficult part of software development, in my opinion. Customers are sometimes intimidated by details, and specific details, provided early in the project, are required with this approach. In addition, customers are not always able to visualize an application from a requirements document. Wireframes and mockups can help, but there’s no question that most end users have some difficulty putting these elements together with written requirements to arrive at a good picture of what they will be getting. * Another potential drawback of pure Waterfall development is the possibility that the customer will be dissatisfied with their delivered software product. As all deliverables are based upon documented requirements, a customer may not see what will be delivered until it’s almost finished. By that time, changes can be difficult (and costly) to implement.

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 – 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.

A Detailed Review of Waterfall Methodology vs Agile Methodology

When we talk about waterfall methodology vs agile, it is essential to notethat they are mature and useful. The use of a specific methodology comes downto the particular project and the organization carrying it out. In this post,you will learn much about waterfall vs agile pros and cons regarding systemdevelopment.

What is the Waterfall Methodology?

Waterfall is the older, more traditional method. Its roots lie in the 1950s,when software was in its infancy and was developed using methods similar tothose used to develop hardware. Most software at that time was developed forgovernment, and especially military purposes, and this method is still highlysuitable for bureaucratic, top-down organizational structures.Waterfall means a linear approach to development. Well, it’s a traditionalapproach that’s founded on strict planning and undertaking the planning bit bybit. When comparing waterfall methodology vs agile methodology, we cancomfortably say that the waterfall methodology is perfect for theorganizations with a hierarchical structure.Here is the sequence of events you need to follow if you plan to use thismethodology: * Gather and document all the needs. Upon commencement of the next work stages, all the tasks will be undertaken depending on this documentation. Here, the customer only takes part in the first and last stage of project performance. * The next step is the design stage. Here the system developers try to get a perfect form to meet all the consumer’s needs. * Coding and unit testing. The primary task of this stage involves coding and perform unit tests. * The next step involves testing the system and user acceptance. * Fixing issues. * The final step entails delivering the completed system to the client.Need Help With App Development?Our experts can help you in developing your next world class apps.The main difference when it comes to agile development vs waterfalldevelopment is that agile methodology has no strict structure when it comes todesigning software. Naturally, there’s no need for documentation in agilebecause the client can see the work’s progress at all times.Basically, agile methodology is more flexible than the waterfall. As a result,it satisfies the customers’ needs and end-users much better. That’s why agileis more helpful for most projects. Additionally, more and more softwaredevelopers are opting for the agile methodology.

Pros of Waterfall Methodology

Superb documentation – every phase of the process is precisely documented toeradicate any shortcuts or misunderstandings.Clear framework – before project commencement, the waterfall methodologyprovides a precise understanding of the project deliverables and timeline.Basically, the project’s full scope is agreed upon in advance by the customersand the development team.Hand-off approach – the technique creates room for a more hands-off approachfrom the client. After finalizing the initial project plan and design, there’sminimal demand for continuous client presence until the review phase.Shared load – the methodology doesn’t take the entire development team’sattention and time. Based on the phase, your development team can focus onother essential tasks within the company.

Cons of Waterfall Methodology

Remember, there is no single system without one or two defects. Here are thecons of waterfall methodology:Changes can be tricky – the fundamentals of the waterfall technique are thatit adheres to a set timeframe and precise steps. After setting these elements,it becomes tricky to undertake changes once the development personnel faces ahurdle. Adaptability is an essential part development team needs to considerbecause it can be difficult for clients to have an entire perception of thesystem before it starts.Little client involvement – a hands-off approach isn’t ideal for all systems.You’ll often come across consumers who need much more participation as theproject proceeds. Waterfall methodology may turn out to be a hindrance forboth parties if there’s no participation framework.Last-minute testing – another con of waterfall is that waterfall isn’t time-bound. Due to this, you may find that your projects may start running behindschedule. Since a lot of time is dedicated to the development phase, your teamwill always have a limited time when it comes to testing out the system.

Comparison- Agile vs waterfall methodology

Agile vs Waterfall comparison tableIn simple terms, agile means ‘the ability to move easily and quickly,’ andthat’s what you’ll get upon utilizing this development methodology. Agile is adevelopment methodology characterized by splitting activities into strict worksegments with regular reviews and plan adaptations.On the other hand, waterfall methodology is a linear sequential model wherethe progress primarily flows in a single direction. Generally, it flowsdownwards via different phases such as requirement collection, systemanalysis, system design, system development, system testing, systemdeployment, and system maintenance.There is a difference between agile and waterfall methodologies, as indicatedabove, but the two are perfect in their individual ways.To summarize this article, let us outline the difference between agile vswaterfall methodology in this section. * While the waterfall is ideal for projects with precise requirements where you don’t expect changes, agile, on the other hand, works best in projects where you’ll need constant requirement changes. * The waterfall is a sequential and easy to manage approach while agile is flexible and lets you undertake changes in all phases. * While it’s not possible to alter the project’s description in the waterfall, you can easily edit in agile. * In waterfall, you can’t edit project needs, and the business analyst defines them once at the start of the project. When it comes to agile, you can frequently change the project requirements.

What is Agile methodology in project management?

The Agile method is a management process that empowers you and your team torespond to the ever-changing nature of business. It uses iterative worksequences, which are also known as sprints.At the heart of any Agile project management is the work. Maintaining focus onthe project allows teams to reflect on immediate needs regularly and adjustcourse as necessary. Following the Agile style also helps create a moreefficient, sustainable and supportive environment that makes it easier foreveryone to deliver their best work.But like anything, Agile doesn’t offer a one-size-fits-all path to success.With Agile, there are options, so let’s take a look at two popularmethodologies, Scrum and Kanban, so you can decide which one is best for yourteam. Additionally, we’ll explore a hybrid approach to project managementwhere Agile meets Waterfall (which is a different, more rigid approach thanAgile altogether).

A hybrid approach: Agile + Waterfall

If your project or work style doesn’t fit into just an agile methodology,infusing it with a Waterfall model might be just what you need. The Waterfallmethodology is simply a list of project activities, broken out into linearsequential phases. Each phase depends on the deliverables of the previous one.By combining this traditional Waterfall methodology with the feedbackmechanisms built into Agile project management, you can uncover issues duringdevelopment and address them quickly. Some scenarios that might benefit from ahybrid approach include:1. You have a short project with defined deliverables and a fixed budget. Byusing the structure of Waterfall and the speed and teamwork that agile projectmanagement is known for. This approach allows you to break the project intosmaller chunks, encouraging further collaboration between the team and theclient/stakeholder, and most importantly, create a product that delivers onits promises.2. You have a project that needs to account for a wide range of stakeholders,mitigate risks and completion within a tight timeline. While an Agile approachis great for limiting risks and staying on deadline, a Waterfall solution isoften best for incorporating information and feedback from a variety ofstakeholders – and by using a hybrid solution, you can accommodate both needseasily.
