The Prototype Methodology is the software development process that allows developers to create only the prototype of the solution to demonstrate its functionality to the clients.
Make all the necessary modifications before developing the actual application using this methodology. The best feature of this software development methodology is that it solves a plethora of issues that often occur in a traditional waterfall model. Feature Driven Development is an iterative approach out of all the software methodologies, intended for use by large teams working on a project using object-oriented technology.
This type of model is good for organizations that are transitioning from a phase-based approach to an iterative approach. Feature Driven methodology is also known as an FDD methodology. Rapid Application Development RAD is an effective methodology that provides much quicker development and higher-quality results than those achieved with the other software development methodologies.
It is designed in such a way that it easily takes the maximum advantage of the software development. The main objective of rapid application development methodology is to accelerate the entire software development process. The goal is easily achievable because it allows active user participation in the development process.
The Spiral Model is a sophisticated model that focuses on the early identification and reduction of project risks. In this software development methodology, developers start on a small scale then explores the risks involved in the project, make a plan to handle the risks, and finally decides whether to take the next step of the project to do the next iteration of the spiral.
The success of any Spiral Lifecycle Model depends on the reliable, attentive, and knowledgeable management of the project. Dynamic Systems Development Model is a software development methodology originally based on the Rapid Application Development methodology. This is an iterative and incremental approach that emphasizes continuous user involvement. Its main aim is to deliver software systems on time and within budget. This model simply works on the philosophy that nothing is developed perfectly in the first attempt and considers it an ever-changing process.
Extreme Programming is an agile software engineering methodology. This methodology, which is shortly known as XP methodology, is mainly used for creating software within a very unstable environment. It allows greater flexibility within the modeling process. The main goal of this XP model is to lower the cost of software requirements. It is quite common in the XP model that the cost of changing the requirements at later stages in the project can be very high.
Joint Application Development JAD is a requirements-definition and user-interface development methodology in which end-users, clients, and developers attend intense off-site meetings to work out and finalize software systems. This methodology aims to involve the client in the design and development of an application.
JAD sessions easily accomplish targeted goals with a series of collaborative workshops. The main focus of this model is to resolve the business problem rather than technical details.
Thus it is most suitable for developing business systems. Lean Development Methodology focuses on the creation of easily changeable software. This Software Development model is more strategically focused than any other type of agile methodology. The goal of this methodology is to develop software in one-third of the time, with a limited budget, and a very less amount of required workflow.
The above software development methodologies are very important which are mostly used for various software development projects. Moreover, all these popular software development methodologies work well in certain projects depending upon the nature of the project.
It often happens that one methodology that is suited for a particular project may not be suited for another project. Moreover, none of these software development methodologies are foolproof as each has its pros and cons.
So, software developers must have information about all these methodologies before selecting any of these development methods for their software development projects.
For better results, it is advisable to consult a professional software development company. He is an accomplished Business Strategist and Tech Visionary with wide-ranging experience in the technology sector.
Home Insights Software Development. Last Updated on Dec 25, Agile Software Development Methodology Agile Software Development methodology is one of the best software development approaches that is used to design a disciplined software management process which also allows some frequent alteration in the development project.
Every step in the development life cycle gives rise to the end-product needed by the next stage in the cycle. Layout design for the product is made from the gathered requirements. The design determines the codes to be written.
This step is the development phase. The testing confirms the resulting product from the development stage, and checks to see if it meets the requirements. In the software development service, six basic steps define the process of software development.
They are:. In software development , requirements for the products to be designed are sourced in this step. For most projects, this step happens to be the primary focus.
Project managers, interested stakeholders gather around to meet and put together the requirements. Utilization of the product, what kind of data goes into the product? And what kind of data is returned by the product as output? After the requirements have been gathered, and questions like above have been answered, analysis of the conditions comes next. The plausibility of putting the elements assembled into the final product is analyzed and carefully studied in detail.
A requirement specification document is created. After completion of the requirements analysis, the development team can then proceed to the next level of making out a product design to be followed throughout the development process. During this step, the creation of the product design from the requirements documentation ensues. Product design assists in the specification of the necessary hardware required to run the product, in other words, the deployment.
It also helps in clearly marking out the general product architecture, depicting the software modules required to be developed and their relationships. The process, also known as the Software Development Life Cycle SDLC , includes several phases that provide a method for building products that meet technical specifications and user requirements. The SDLC provides an international standard that software companies can use to build and improve their computer programs.
It offers a defined structure for development teams to follow in the design, creation and maintenance of high-quality software. The aim of the IT software development process is to build effective products within a defined budget and timeline. There are six major steps in the software development life cycle, including:. Needs identification is a market research and brainstorming stage of the process.
Before a firm builds software, it needs to perform extensive market research to determine the product's viability. Developers must identify the functions and services the software should provide so that its target consumers get the most out of it and find it necessary and useful.
There are several ways to get this information, including feedback from potential and existing customers and surveys. The IT teams and other divisions in the company must also discuss the strengths, weaknesses and opportunities of the product. Software development processes start only if the product satisfies every parameter necessarily for its success. Requirement analysis is the second phase in the software development life cycle. Here, stakeholders agree on the technical and user requirements and specifications of the proposed product to achieve its goals.
This phase provides a detailed outline of every component, the scope, the tasks of developers and testing parameters to deliver a quality product. The requirement analysis stage involves developers, users, testers, project managers and quality assurance. This is also the stage where programmers choose the software development approach such as the waterfall or V model.
The team records the outcome of this stage in a Software Requirement Specification document which teams can always consult during the project implementation. Design is the third stage of the software development process. Here, architects and developers draw up advanced technical specifications they need to create the software to requirements.
Stakeholders will discuss factors such as risk levels, team composition, applicable technologies, time, budget, project limitations, method and architectural design. The Design Specification Document DSD specifies the architectural design, components, communication, front-end representation and user flows of the product. This step provides a template for developers and testers and reduces the chances of flaws and delays in the finished product.
The next stage is the development and implementation of the design parameters.
