Among these, waterfall project management is one of the more interesting ones, seeing as it stems from the old days of the construction and manufacturing industries; it was not specifically designed with software development in mind.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">So, what is the waterfall methodology? Essentially, we\u2019re talking about a <strong><a href=\"https:\/\/www.proprofsproject.com\/blog\/project-management-methodologies\/\">project methodology<\/a><\/strong> in which the project is completed across distinct stages, itching step by step to the final release to end-users. <strong>To put it simply &#8211; you create a big plan in the beginning, and proceed along with a linear execution<\/strong>; hoping that no changes to the plan will be needed.&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">The <strong>waterfall approach to project management is what you get when you apply traditional project management to software development<\/strong>. With that in mind, there\u2019s no single inventor of Waterfall; that\u2019s just the name that this methodology got once other methodologies were implemented &#8211; such as <strong><a href=\"https:\/\/www.proprofsproject.com\/blog\/agile-project-management-software\/\">agile project management<\/a><\/strong>.&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Many people believe that the waterfall methodology of project management isn\u2019t the best one when it comes to software development. As we\u2019ve mentioned above, this methodology was inherited from the construction industry, in which further iterations weren\u2019t an option.<\/span><span style=\"font-weight: 400;\">&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">In order to give you an idea of a waterfall model example project, imagine the construction of a bridge. Once you\u2019ve completed the foundation, you can\u2019t improve it any further. But seeing as software is much more dynamic and prone to changes, the waterfall approach to project management isn\u2019t always the best idea. However, there are some pros to using this approach as well; so we\u2019ll explore both sides of the coin below!<\/span><\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_17 counter-hierarchy ez-toc-grey\">\n<nav><ul class=\"ez-toc-list ez-toc-list-level-1\"><li class=\"ez-toc-page-1 ez-toc-heading-level-2\"><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.proprofsproject.com\/blog\/waterfall-project-management-methodology\/#Phases_of_Project_Management_in_Waterfall_Methodology\" title=\"Phases of Project Management in Waterfall Methodology\">Phases of Project Management in Waterfall Methodology<\/a><\/li><li class=\"ez-toc-page-1 ez-toc-heading-level-2\"><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.proprofsproject.com\/blog\/waterfall-project-management-methodology\/#Advantages_of_Using_Waterfall_Project_Management_Methodology\" title=\"Advantages of Using Waterfall&nbsp;Project Management Methodology\">Advantages of Using Waterfall&nbsp;Project Management Methodology<\/a><\/li><li class=\"ez-toc-page-1 ez-toc-heading-level-2\"><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.proprofsproject.com\/blog\/waterfall-project-management-methodology\/#Disadvantages_of_Waterfall_Project_Management_Methodology\" title=\"Disadvantages of Waterfall&nbsp;Project Management Methodology\">Disadvantages of Waterfall&nbsp;Project Management Methodology<\/a><\/li><li class=\"ez-toc-page-1 ez-toc-heading-level-2\"><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.proprofsproject.com\/blog\/waterfall-project-management-methodology\/#Where_You_Should_Use_Waterfall\" title=\"Where You Should Use Waterfall\">Where You Should Use Waterfall<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Phases_of_Project_Management_in_Waterfall_Methodology\"><\/span><b>Phases of Project Management in Waterfall Methodology<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Naturally, the specific phases for any project may vary according to the details; especially in regards to which <\/span><strong><a href=\"https:\/\/www.proprofsproject.com\/blog\/best-project-management-software\/\">project management software<\/a><\/strong><span style=\"font-weight: 400;\"> you use. Generally, though, they include the following steps:<\/span><\/p>\n\n\n\n<h3><b>#1 Requirements<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">In this phase of the project, the team gathers a lot of information regarding the requirements of the project. This is done in many different ways; from questionnaires and interviews to team brainstorming sessions. If you were designing software for cash registers, for example; this is where you\u2019d do market research on the expenses and different features you need. Once this phase is done, you should be clear about what project requirements you\u2019re facing &#8211; and produce a document on this that should be circulated throughout your team.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>#2 Design<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Using the documents that you\u2019ve established in the requirements phase, your team will work on the system design. In this phase, there will be no specific coding; you\u2019ll just be settling specifics like hardware requirements or the programming language you\u2019ll use. This is particularly important for the waterfall methodology, as it focuses on getting everything right in the first iteration.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>#3 Implementation<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">This is the first phase where you\u2019ll actually do some coding. The team\u2019s programmers will use the information from the design stage to come up with a functional product. Generally, they\u2019ll create different segments of the code in different pieces, to be assembled and integrated at the end of the implementation phase or at the beginning of the testing phase.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>#4 Testing<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Once you\u2019re finished with all of the coding, the actual testing of your software can begin. So, going back to the example of cash register software, this is where you test your product on applicable hardware. The testers file methodical reports that document any issues, often supported by <a href=\"https:\/\/testrigor.com\/blog\/test-automation-tools\/\" target=\"_blank\" rel=\"noreferrer noopener\">automation testing tools<\/a> that help validate features and catch defects more efficiently before release. And if there are any truly big problems, you may need to bring your project back to phase one.\u00a0<\/span><\/p>\n\n\n\n<h3><b>#5 Deployment<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">At this stage in our waterfall model example project, all of the production work is largely complete; all that\u2019s left is for your team to submit the final iteration for release and further maintenance.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>#6 Maintenance&nbsp;<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">At this point, the product is finished and the clients are already using it. In our waterfall project example, your software for cash registers is being implemented in retail stores. At this point, you may have to produce updates and patches that deal with potential issues.<a href=\"https:\/\/www.ninjaone.com\/blog\/patch-management-overview-with-explanations\/\">&nbsp;<\/a><\/span><\/p>\n\n\n\n<p><pre><strong>Read More: <a href=\"https:\/\/www.proprofsproject.com\/blog\/critical-chain-project-management\/\">Critical Chain Project Management: Everything You Need to Know<\/a><\/strong><\/pre><\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Advantages_of_Using_Waterfall_Project_Management_Methodology\"><\/span><b>Advantages of Using Waterfall&nbsp;Project Management Methodology<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">While the waterfall project management method isn\u2019t the most viable when it comes to software development, there are some advantages to using it as well.<\/span><\/p>\n\n\n\n<h3><b>1. Detailed Documentation<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Seeing as this project management methodology doesn\u2019t make it easy to return to a previous step, you are guided into making a really comprehensive and detailed project documentation from the very beginning; listing any requirements that come to mind.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>2. No Lost Knowledge<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">With such a comprehensive knowledge base in the project, you don\u2019t stand to lose much if anyone decides to leave. And also, if you take on someone new, you won\u2019t have to spend a lot of time to acquaint them with the project. They can easily familiarize themselves by going through the project documentation.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>3. Better Time Management<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Seeing as everyone knows what their work will be from the very start, they can plan out their workflow better from the beginning. This <strong><a href=\"https:\/\/www.proprofsproject.com\/blog\/productivity-hack-tips-managing-time\/\">reduces the instances of wasting time<\/a><\/strong> in back and forth interactions that can cause project delay.&nbsp;&nbsp;<\/span><\/p>\n\n\n\n<h3><b>4. Clarity<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">As you may have gathered, waterfall projects have very clearly understandable and separate phases. Because of that, the management is pretty straightforward, and even people who aren\u2019t developers can understand what\u2019s going on.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>5. Precise Client Expectations<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">With the waterfall method, clients are aware of both the project timeline and the production costs in advance. That way, they\u2019re able to manage their own cash flow with more ease.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>6. No Client Input Needed<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Once the first requirements stage is complete, there is next to no client input required. Sure, there might be occasional status meetings, approvals, and reviews; but you don\u2019t have to coordinate with the client on a daily basis.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>7. Progress Measuring<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Seeing as waterfall projects have a very clear outline, measuring progress is quite easy; <strong><a href=\"https:\/\/www.proprofsproject.com\/blog\/what-is-a-gantt-chart\/\">using a Gantt chart<\/a><\/strong> is more than enough.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>8. Better design<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Because of the importance of the design phase for the waterfall project management methodology, the design of the product is bound to be better and more detailed than it otherwise would. Thus, products made this way are generally more cohesive, as all the features are designed right from the start.&nbsp;<\/span><\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Disadvantages_of_Waterfall_Project_Management_Methodology\"><\/span><b>Disadvantages of Waterfall&nbsp;Project Management Methodology<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">On the other hand, there are also some disadvantages to using the Waterfall method. We\u2019ll take a look at them in detail here.<\/span><\/p>\n\n\n\n<h3><b>1. No Going Back<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">When you\u2019re done with one stage and activity, going back to make alterations proves to be expensive and difficult. While this does make the design and <strong><a href=\"https:\/\/www.proprofsproject.com\/blog\/project-planning-guide\/\">planning<\/a><\/strong> better, it also puts a lot of pressure on the initial plan being correct.<\/span><\/p>\n\n\n\n<h3><b>2. Can\u2019t Make A Mistake In The First Phase<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Seeing as everything relies so heavily on the first requirements phase going over well; the project is basically doomed if you make any sort of error here.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>3. Deadline Inflation<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">With the linear nature of the waterfall methodology in mind, if you\u2019re late with one activity &#8211; all the subsequent activities won\u2019t be finished on time either; including the final project deadline.&nbsp;<\/span><\/p>\n\n\n\n<h3><b>4.&nbsp;<\/b><b>Buggy Software&nbsp;<\/b><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Seeing as the testing is only done once the project nears its end, many development teams rush that phase of the project in order to meet their deadlines and acquire the incentives. Consequently, this small win produces a sub-par product with a lot of bugs.&nbsp;<\/span><\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Where_You_Should_Use_Waterfall\"><\/span><b>Where You Should Use Waterfall<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">When it comes to where you should use the waterfall project management methodology, consider it for projects where:<\/span><\/p>\n\n\n\n<ul><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">The requirements, scope, and budget are initially fixed; a one-off thing where you wouldn\u2019t do any further development;<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">There is an accurate work estimation; you\u2019ve already performed the same kind of work before, and you know the technology well;<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">There is no space to iterate (like developing software for heart rate monitors)<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">The project is not high-risk (you\u2019re making a clone of a functional and tested product)<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">You have a particularly hard deadline.<\/span><\/li><\/ul>\n\n\n\n<p><strong>On the other hand, we don\u2019t recommend using waterfall in projects where:<\/strong><\/p>\n\n\n\n<ul><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">The quality is less important than the working prototype (if you need to test for market demand first);<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">When you\u2019re not sure what the final product needs to look like;<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">When a client is not sure of what they require from the start;<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">When the product is designed for an industry in which standards change rapidly;<\/span><\/li><li><span style=\"font-weight: 400;\"> &nbsp; &nbsp; <\/span><span style=\"font-weight: 400;\">When user feedback is an essential part of the production cycle<\/span><\/li><\/ul>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<p><span style=\"font-weight: 400;\">Now everything being said and covered about waterfall management, let\u2019s take a look at some frequently associated questions with project management types:<\/span><\/p>\n\n\n\n<p><b>Q. What is the Difference Between Waterfall and Agile?<\/b><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">In many cases, Agile is often mentioned besides Waterfall, as a stark contrast. And the primary difference between these two methodologies is that waterfall isn\u2019t good for projects which require constant change and adaptability; while agile is the opposite. That\u2019s why more software development projects use the agile methodology. With agile, the project culture allows for making significant changes at any point in the development cycle.&nbsp;<\/span><\/p>\n\n\n\n<p><b>Q. How does a Waterfall Model Work?<\/b><\/p>\n\n\n\n<p>Waterfall Model works in sequential order, wherein all the developments are divided into specific stages. The whole project is planned and designed in a linear manner and there is no room for big errors or changes. It is a conceptual model completely in sync with SDLC processes.<\/p>\n\n\n\n<p><b>Q. Is Agile more Expensive Than Waterfall?<\/b><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">If you\u2019re asking about whether agile is more costly than waterfall &#8211; there is no right answer. Or rather, this solely depends on the nature of the project. Should the project require making any significant changes at any phase past the initial one; agile will be more affordable than waterfall.&nbsp;<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>There are many approaches to project management, especially in software development.
