Types of Software Engineering

Agile Development
Agile Development

The term agile management is applied to an iterative, incremental method of managing the design and build activities of engineering, information technology and other business areas that aim to provide new product or service development in a highly flexible and interactive manner, based on the principles expressed in the Manifesto for Agile Software Development.

Big Bang Model
Big Bang Model

The Big Bang model is an SDLC model where we do not follow any specific process. The development just starts with the required money and efforts as the input, and the output is the software developed which may or may not be as per customer requirement.

Evolutionary Prototyping Model
Evolutionary Prototyping Model

1. The prototyping model 2. The spiral model 3. Concurrent development model 1. The Prototyping model. Prototype is defined as first or preliminary form using which other forms are copied or derived. Prototype model is a set of general objectives for software. It does not identify the requirements like detailed input, output.

Iterative and Incremental Method
Iterative and Incremental Method

The Incremental approach 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. It involves both development and maintenance.

Iterative Model
Iterative Model

SDLC Iterative Model - Learn Software Development Life Cycle starting with SDLC overview and covering various models like waterfall model, Iterative Model, Spiral Model, V-Model, Big Bang Model, Agile Model, RAD Model and Software Prototype Model.

Spiral Method (SDM)
Spiral Method (SDM)

The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model). The baseline spiral, starting in the planning phase, requirements are gathered and risk is assessed. Each subsequent spirals builds on the baseline spiral.

The Incremental Development Model
The Incremental Development Model

Incremental model in software engineering is a one which combines the elements of waterfall model in an iterative manner. It delivers a series of releases called increments which provide progressively more functionality for the client as each increment is delivered.

The Phases of Iterative Development
The Phases of Iterative Development

Iterative and Incremental development is any combination of both iterative design or iterative method and incremental build model for software development. The combination is of long standing and has been widely suggested for large development efforts.

The Principles of Agile Methods
The Principles of Agile Methods

The Process of Prototype Development
The Process of Prototype Development

Software prototyping is a way for software publishers to get a preview of a product they would like to develop before they go to all the trouble to manufacture, advertise, and sell that product. The prototype gives an idea of how the product can be manufactured and if it will meet the needs of the end user.

The Spiral Model
The Spiral Model

A spiral model is made up of set different framework activities made by the software engineering team. Take a look at the following spiral model diagram: A spiral model is divided into some framework activities, also called task regions.

The Waterfall Model
The Waterfall Model

The waterfall model is a sequential design process, often used in software development processes, where progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance.

V-Shaped Model
V-Shaped Model

In software development, 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. Instead of moving down in a linear way, the process steps are bent upwards after the coding phase, to form the typical V shape.
