Web Application Development Process and the Agile Methodology
The Web Applications Lifecycle Model was developed as a way to describe software development cycles used in creating web applications. This is also known as the Software Development Life Cycle or the SDP. This model was created by Robert C. Martin, who used it in his popular book, A Brief History of Software Development. The aim of this model is to provide developers with an idea about the overall development cycle. The model can be considered as a tool for software project management, which aims to manage and track the life cycle of software projects from conception to delivery.
The software development life cycle (SDLC) is the lifecycle within which an application is designed and built. The development team begins by defining the purpose and essence of the project. Next, they create the software itself. They integrate it into the organization’s existing platform and finally test and complete it. Once completed, they make minor adjustments that the team needs to implement.
The main purpose of the web applications lifecycle model is to facilitate the multiple programmers working on the project. In a typical software development process, there are usually two or more programmers working on different branches. Due to the branching nature of the development process, there is a risk of duplicate code in both the source code and the resulting compiled form. The web application lifecycle model effectively prevents developers from duplicating their efforts and ensuring that only the final product is released.
Most importantly, the web applications lifecycle model allows developers to become familiar with the source code. This will ensure that the developers can make reasonable changes to the source code without disrupting the working of the project. In some cases, the source code may become complex. In order to avoid breaking the code and disturbing the working environment, developers should become familiar with the source code prior to making any changes. In a typical software development cycle, the process goes like this:
During the project management stage, there are three phases which include the pre-phase, the preparation phase, and the post-phase. During the pre-phased phase, there are several issues that need to be addressed. These include issues related to functionality definition, infrastructure specification, and usability and security testing. With proper planning, these issues can be addressed by developers in an efficient manner, leading to an efficient web application development process.
In the preparation phase, developers need to gather technical and business data as well as customer requirements. With the data in hand, they can now work on the infrastructure specification and design phase. With the design phase, they can now work on implementing software architecture. With this functionality defined, developers can now integrate the software architecture with custom web application development.
With this integration process, companies need not start from the designing stage. Instead, they can start from the development phase and build a prototype for testing. This allows companies to make significant savings on both time and money. However, most companies still prefer to start by designing and then integrate new web applications into the business impact solution.
When companies adopt an agile methodology while working on the web application development process, it helps them meet the requirements of clients more quickly. The team members are also more productive as projects come at a quicker pace. Additionally, each team member is better utilized as teams come together in an integrated manner. With these benefits, project managers are able to ensure maximum customer value by using an effective web application development process. More importantly, they are able to meet the business impact needs of their customers.
