A design approach clearly defines all the architectural modules of the product along with securiyy communication and data flow representation with the external and third party modules if any.

Engineering Buzz: IT Information Security – SDLC Notes

Agile introduces the concept of fast delivery to customers using prototype approach. After the product is released in the market, its maintenance is done for the existing customer base. The programming code is generated as per DDS during this stage. The product may i2t042 be released in a limited segment and tested in the real business environment UAT- User acceptance testing. Customer interaction is the backbone of Agile methodology, and open communication with minimum documentation are the typical features of Agile development environment.

Each process model follows a Series of steps unique to its type, in order to ensure success in process of software development. A typical Software Development life cycle consists of the following stages: Based on the requirements specified in SRS, usually more than one design approach for the product architecture is proposed and documented in a DDS – Design Document Specification.

The outcome of the technical feasibility study is to define the various technical approaches that can be followed to implement the project successfully with secruity risks. Don’t You Think this Awesome Post should be shared?? Developers have to follow the coding guidelines defined by their organization and programming tools like compilers, interpreters, debuggers etc are used to generate the code.


Planning for the quality assurance requirements and identification of the risks associated with the project is also done in the planning stage.

Once the product is tested and ready to be deployed it is released formally in the appropriate market. If the design is performed in a detailed and organized manner, code generation can be accomplished without much hassle.

This tutorial also gives you an insight into the pros and cons and the practical applications of the SDLC models discussed. SDLC is a process followed for a software project, within a software organization.

It is performed by the senior members of the team with inputs from the customer, the sales department, market surveys and domain experts in the industry. There are various software development life cycle models defined and designed which are followed during software development process. SDLC is the process consisting of a series of planned activities to develop or alter the software products. Such models are suitable for projects with very clear product requirements and where the requirements will not change dynamically during the course of project completion.

Sequential means that the next phase can start only after the completion of first phase. Agile is the most popular model used in the industry. The software development life cycle SDLC is a framework defining tasks performed at each step in the software development process. The following figure is a graphical representation of the various stages of a typical SDLC. This information is then used to plan the basic project approach and to conduct product feasibility study in the economical, operational, and technical areas.

It is also called as Software development process.

The life cycle defines a methodology for improving the quality of software and the overall development process. The programming language is chosen with respect to the type of software being developed. The information in this tutorial will help the project managers decide what SDLC model would be suitable for their project and it would also help the developers and testers understand basics of the development it204 being used for their project.


Then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment. It consists of a detailed plan describing how to develop, informatiion, replace and alter or enhance specific software. SRS is the nofes for product architects to come out with the best architecture for the product to be developed.

Big Bang model is a random approach to Software development and is suitable for if2042 or academic projects. However this stage refers to the testing only stage of the product where products defects are reported, tracked, fixed and retested, until the product reaches the quality standards defined in the SRS.

This is done through. These models are also referred as “Software Development Process Models”.


It aims to be the standard that defines all the tasks required for developing and maintaining software. Iterative and Spiral models are more accommodative in terms of change and are suitable for projects where the requirements are not so well defined, or the market requirements change quite frequently.

Following are the most important and popular SDLC models followed in the industry: Agile divides the project into small iterations with specific deliverable features. In this stage of SDLC the actual development starts and the product is built.
