Agile and Waterfall are two very popular software development models used in corporations and technology companies these days. So, what exactly are Agile model and Waterfall model? The main difference between these two models? Which one is better? AMELA will help you understand these two models in this article! What is The Agile Model? What is The Waterfall Model? Agile Model [caption id="attachment_9122" align="aligncenter" width="1864"] The process of the agile model[/caption] It's a method of building and developing software projects. This method significantly shortens development time, repeating tests in a short period of time, thereby developing the project quickly. Waterfall Model [caption id="attachment_9124" align="aligncenter" width="927"] The process of the waterfall model[/caption] It is a cyclical loop method. The method helps deploy a software project sequentially and thus the project development team only moves to the next development or testing phase if the previous step is completed successfully. Difference Between the Agile Model and Waterfall Model [caption id="attachment_9126" align="aligncenter" width="472"] Differences between agile and waterfall[/caption] + Agile allows customers to request changes to requirements or additional specifications at any time during the development process. Waterfall must make changes to specs and other specification requirements before development begins. + Agile can provide services at each iteration so it will be fast. As for Waterfall, it only allows providing services after completing all processes, so it will take more time. + Documentation is not required in the Agile development model; however, if it is an effective method of conveying information, documentation should still be created. In contrast, with the Waterfall development model, documentation needs to be created for each process and connected to the next process. Additionally, documentation also serves as proof of the project once the entire process is complete. + Agile requires regular testing for each implementation, while Waterfall requires testing only during the testing phase. + In Agile development, each engineer will perform his or her own development work without having to have a specific area of expertise; but with the Waterfall model, it is imperative that one person is in charge of each process. + The Agile method helps you learn practically through iterative developments. Because you are responsible for all rounds of development, you will have more experience and be more adaptable in many areas. Waterfall development is more about using people with expertise and experience, so training/recruiting human resources is relatively easy. + Agile can improve the process for each iteration; If it's not okay this time, it's completely possible to improve next time. However, with Waterfall, we can only see the points that need improvement after the project is completed, so we can only draw and apply experience to the next projects. Which One is Better? Each model has different advantages and disadvantages, it is important to apply the appropriate model depending on each project case.

If you have read the article App Development For Your Business, you will know that app development in particular, or software development in general has to go through many steps, and the cost is not cheap. Therefore, to ensure that the money and effort spent on software development are right, businesses need to plan meticulously and in detail in choosing the right software developer for them. How to outsource software development? And What does a business need to know before outsourcing software development? Before going into how to outsource software development, we need to know about 2 terms, Procurement, and Request For Proposal (RFP). It sounds so technical, but you can simply understand one is the act of buying, and selling services, and the other is bidding. Procurement as a general business practice can be defined as: “The act of obtaining or buying goods and services. The process includes the preparation and processing of a demand as well as the end receipt and approval of payment. It often involves: ・Standards determination; ・Supplier research and selection; ・Value analysis; ・Price negotiation; and ・Making the purchase.” In other words, procurement refers to the basic process of securing goods or services from an external business or consultant. A request for proposal, as the name suggests, is an invitation for external businesses or consultants to apply to provide your company with specific goods or services. Investopedia.com describes RFP in the following terms: “A request for proposal (RFP) is a type of bidding solicitation in which a company or organization announces that funding is available for a particular project or program, and companies can place bids for the project’s completion. It outlines the bidding process and contract terms and provides guidance on how the bid should be formatted and presented.” Additionally, an RFP establishes specifications describing the particular solution that the company is seeking and the evaluation criteria according to which proposals will be assessed. We understand the key terms and now dig deeper into the way we become a partner with software developers. Make Your Needs Clear Understanding your needs, your proposal will also be clear and easy to understand. So, how do you determine the exact requirements of your business? Just by understanding the term “need assessment” you will be able to identify gaps in your proposal and analyze them. Businessdictionary.com defines needs assessment — otherwise known as “gap analysis” — as: “A technique that businesses use to determine what steps need to be taken in order to move from its current state to its desired, future state. Gap analysis consists of: ・Listing of characteristic factors (such as attributes, competencies, performance levels) of the present situation (‘what is’), ・Listing factors needed to achieve future objectives (‘what should be), and then ・Highlighting the gaps that exist and need to be filled. Gap analysis forces a company to reflect on what kind of business it is at present and to ask what kind of business it wants to be in the future.” In other words, don’t just take another company’s proposal template and apply it…
