If the design is performed in a detailed and organized manner, code generation can be accomplished without much hassle. A design approach clearly defines all the architectural modules of the product along with its communication and data flow representation with the external and third party modules if any.

The internal design of all the modules of the proposed architecture should be clearly defined with the minutest of the details in DDS.

Big Bang model is a random approach to Software development and is suitable for small or academic projects. Agile introduces the concept of fast delivery to customers using prototype approach. This DDS is reviewed by all the important secueity and based on various parameters as risk assessment, product robustness, design modularitybudget and time constraintsthe best design approach is selected for the product.

Planning for the quality assurance requirements and identification of the risks associated with the project is also done in the planning stage. A typical Software Development life cycle consists of the following stages: It is securitu called as Software development process.


Don’t You Think this Awesome Informatiln should be shared?? Software Requirement Specification document which consists of all the product requirements to be designed and developed during the project life cycle. Sequential means that the next phase can start only after the completion of first phase.


In this stage of SDLC the actual development starts and the product is built. 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.

It aims to be the standard that defines all the tasks required for developing and maintaining software. These models are also referred as “Software Development Process Models”. 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. The product may first be released in a limited segment and tested in the real business environment UAT- User acceptance testing.


The life cycle defines a methodology for improving the quality of software and the overall development process. Agile is the most popular model used in the industry.

After the product is released in the market, its maintenance is done for the existing customer base.

The following figure is a graphical representation of the various stages of a typical SDLC. Noets outcome of the technical feasibility study is to define the various technical approaches that can be followed to implement the project successfully with minimum risks.


SDLC is a process followed for a software project, within a software organization. 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 ingormation in the SRS. This is done through.

SDLC is the process consisting of a series of planned activities to develop or alter the software products. Once the requirement analysis is done the next step is to clearly define and document the product requirements and get them approved from the customer or the market analysts. Requirement analysis is the most important and fundamental stage in SDLC.


SRS is the reference for product architects to come out with the best architecture for infoemation product to be developed. 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. 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.

Sometime product deployment happens in stages as per the organizations. This tutorial also noges you an insight into the pros and cons and the practical applications of the SDLC models discussed.

Then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment.

The software development life cycle SDLC is a framework defining tasks performed at each step in the informationn development process.

The programming code is generated as per DDS during this stage. Once the product is tested and ready to be deployed it is released formally in the appropriate market.

It consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The programming language is chosen with respect to the type of software being developed.
