This is the second phase of the Software Development Life Cycle (SDLC). This phase clearly illustrates the entire project’s scope with the related issues, risks, and opportunities.
Requirement Gathering is a process of researching and documenting the project requirements. Requirement gathering plays a vital role in the overall success of the project.
Business Requirements relate to a business objective, goals, and vision. They provide the scope of business needs and problems that should be addressed.
Software requirements break down the steps that are needed to meet the business requirements. While business requirements state the ‘Why’ of a project, software requirements focus on the ‘What.’
This phase is crucial and involves stakeholders’ input into this document. Then, an overall system architecture is defined, which serves as an input for the next SDLC phase.
Software design is a process to transform user requirements, i.e., an SRS document into a suitable form, which helps the software developer in software coding and implementation. It is the first phase of SDLC, which moves from the problem domain to the solution domain.
Architecture Design is the highest level of the abstract version of the system. It also identifies the system as many components interacting with each other. At this level, the designers get a better idea of the proposed solution domain.
Here, the problem is decomposed into a set of modules. The control relationship and the interface among the various modules are identified in this phase of SDLC. Structure charts and diagrams are used as representation techniques.
Detail design is taken into consideration after High-level design is completed. In detailed design, each module is examined to design the data structures and algorithms. This phase is more detailed about the module and its implementation.
SUFFICIENCY AND COMPLETENESS: A good software design ensures the software’s sufficiency and completeness and ensures that the software is adequate and fully built.
Prototyping or software prototyping is creating an incomplete version of a software product or application being developed. We can say it is a working model of software with limited functionality.
There are different types of prototyping used in the software development industry. The following are the major types of prototypes preferred by software developers in the software development process.
Throwaway / Rapid Prototyping: Throwaway Prototyping is also called Rapid or Close Ended Prototyping. Minimum requirements analysis and fewer efforts are required in this type of prototyping. As soon as requirements are understood, this prototype is discarded, and the original software is developed with a better understanding of user requirements.
Evolutionary Prototyping: Evolutionary Prototyping, also known as Breadboard Prototyping, is based on creating an actual functional prototype with minimum functionalities at the beginning of the software development process. When using Evolutionary Prototyping, only the well-understood requirements are added to the prototype.
Incremental Prototyping: Incremental Prototyping refers to building multiple functional prototypes of various subsystems. Then, all the available prototypes are integrated to form a complete system. This method is beneficial to reduce the feedback time between the user and the software development team.
Extreme Prototyping: Extreme Prototyping is used in Web Development, and it consists of three sequential phases. In the first phase, a basic prototype with all the existing pages is presented in HTML format. Then in the second phase, data processing is simulated using a prototype service layer. And in the third phase, the services are implemented and integrated with the final prototype.
Reduced Time & Costs: When changes are detected later in the software development, it costs much to implement them. The early determination of what the user wants through prototyping can result in faster and less expensive software.
Improved and Increased Users Involvement: The prototype allows the user to interact and provide feedback on it. The user knows and understands the problem domain better than the software developer or software development team. Prototype solves the misunderstanding through user involvement. Also, it helps the final product be developed to give more satisfaction to the user.
Improve Product Quality: With the prototype, users can anticipate the needed changes and potential project hurdles, and potential end-result disasters. Strong prototyping can ensure improved product quality for years to come.
Software Development Company In BangladeshInsufficient Analysis: Focusing on a limited prototype can distract a software developer from properly analyzing the software project. It can lead to poorly engineered final products or incomplete specifications. This also causes end software products to be very hard to manage.
User Confusion: Often, users, by mistakes or confusion, consider the prototype as a finished product. Also, they expect the prototype to function accurately as the end product, whereas that is not the intent of the software developer.
Developer Misunderstanding of Users Objectives: For a successful software development project, it is important to have a software developer and user be on the same page and share the same project objectives. If the user requires all the features of a prototype to be included in the final software product, this can create team and mission conflicts.
Excessive Development Time: The key property of a prototype is that it is supposed to be done quickly. If software developers lose sight of this fact, it can lead to complexities. In such cases, the user can be stuck in debate and hold up the software development team underlying the software development project.
Expenses of Implementing Prototyping: The startup cost of building a dedicated development team focused on prototyping may be expensive. Besides, many software development companies have their software development methodologies in place, and changing them can mean retraining and retooling their software developers. This may add to the extra costs.
Developer Attachment to prototype: Software developers can also become attached to the prototype as they have spent time and effort on it. This may create development issues like converting a limited prototype into a final software product.
Once the design phase is over, the next phase in the Software Development Life Cycle (SDLC) is coding. This is the actual phase where software development is done. This SDLC phase is also known as implementation.
Once the design phase is over, the next phase in the Software Development Life Cycle (SDLC) is coding. This is the actual phase where software development is done. This SDLC phase is also known as implementation.
In this phase, software developers start to build the entire software product or application by writing code. Multiple programming languages are used to write code in the software development process.
In the coding and implementation phase, tasks are divided into smaller units or modules and assigned to developers. Few developers might write a small project, while a large project may need a complete software development team. Coding is the most extended phase of the Software Development Life Cycle.
Front End Development, also known as client-side development, is developing HTML, CSS, and Javascript for a website or Web Application that users can see and interact with directly. The web designer and web developer creating the user interface are called front-end developers.
The challenges associated with front-end development are that the tools and frameworks used to create a front-end application, website, or web application change constantly. So, front-end developers need to be aware of how the field is developing.
Front End Frameworks are the pioneer blocks of the software development process. But there are various options to choose from when it comes to building web applications that rank higher on UI and UX. Here is the curated list of Top Front End Frameworks for web development in 2023.
React: Being one of the simplest frameworks to learn, React was developed at Facebook to fix code maintainability issues. Reactjs is basically an open-source front-end javascript framework for building user Interfaces or UI components. React Official Website.
Angular: Officially launched in the year 2016, Angular JS was developed by Google to bridge the gap between technology and conventional concepts. If you want to build mobile or web apps, Angular is the perfect framework for you. Besides, this front-end framework is also used to develop multi-page and progressive web apps. Due to this reason, companies like BMW, Blender, Xbox, Forbes, and others deploy applications with Angular. AngularJS Official Website.
Vuejs: VueJS is a very simple and straightforward Front End Framework. VueJS is versatile and can do multitask. It can handle Web Applications, Mobile apps as well as Progressive Web Applications. Companies like Alibaba, 9gag, Xiaomi, and Reuters are some well-known users of this framework.
jQuery: jQuery was introduced in 2006 and is one of the oldest front-end frameworks. is easy and simple to use. It also minimizes the need for writing lengthy JavaScript codes. The recent update in this framework enables front-end developers to build native mobile applications.
