Different models in software engineering

Rational Unified Process model fragments the development process in the inception phase, elaboration phase, construction and transition phase. Uses: Projects that are large-sized and carry high amount of risk prefer this model. It is one of the software engineering models which do not adhere to a particular process per se. Uses: This methodology is best suited for small projects. It does not require high-level planning and it is an easy model.

Rapid Application Development methodology does not require planning and best applied in projects that require customization from the customer. This model builds prototypes of functional modules which are incorporated into the software after completion. The advantage of this model is that it is less time-taking, and also engages the customer.

Their feedback is sought and the product is developed. RAD might fail, if the project cannot be divided into modules. Although there are many types of software development models which are applied across various development projects, the ideal model is applied depending on the project size and requirements.

Here is a statistical chart on cost comparison of the above-mentioned software models. The statistics for models with minor applications that encapsulate a thousand functions. The Waterfall model is comparatively an expensive software development model. The other models are less in terms of cost. However, Waterfall is the most widely applied model in spite of the fact that it requires high cost.

It is a process that is followed by a software development project by a software organization. This results in more frequent incremental releases with each release building on previous functionality. Thorough testing is done to ensure that software quality is maintained. Visual Paradigm provides a rich set of project management tools that help software team perform major development activities and manage the artifact created throughout the process.

Kick-start any size of IT projects with automated guide-through process, with step-by-step instruction, input references and samples. Develop deliverables incrementally and collaboratively with your team members. People are facing great deal of difficulties on Project Management such as steep learning curve and high costs hiring certified professionals.

There are many different software processes but all involve: Specification — defining what the system should do; Design and implementation — defining the organization of the system and implementing the system; Validation — checking that it does what the customer wants; Evolution — changing the system in response to changing customer needs.

Types of Software Process Model Software processes, methodologies and frameworks range from specific prescriptive steps that can be used directly by an organization in day-to-day work, to flexible frameworks that an organization uses to generate a custom set of steps tailored to the needs of a specific project or group. The most used, popular and important SDLC models are given below: Waterfall model V model Incremental model RAD model Agile model Iterative model Spiral model Prototype model Waterfall Model The waterfall model is a breakdown of project activities into linear sequential phases, where each phase depends on the deliverables of the previous one and corresponds to a specialisation of tasks.

V Model The V-model represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Incremental model The incremental build model is a method of software development where the model is designed, implemented and tested incrementally a little more is added each time until the product is finished. Iterative Model An iterative life cycle model does not attempt to start with a full specification of requirements by first focusing on an initial, simplified set user features, which then progressively gains more complexity and a broader set of features until the targeted system is complete.

Spiral model The spiral model, first described by Barry Boehm in , is a risk-driven software development process model which was introduced for dealing with the shortcomings in the traditional waterfall model. Agile model Agile is an umbrella term for a set of methods and practices based on the values and principles expressed in the Agile Manifesto that is a way of thinking that enables teams and businesses to innovate, quickly respond to changing demand, while mitigating risk.

Managing Software Process with Visual Paradigm Visual Paradigm provides a rich set of project management tools that help software team perform major development activities and manage the artifact created throughout the process.

This process continue until the customer is satisfied with the system. Once a user is satisfied, the prototype is converted to the actual system with all considerations for quality and security.
