There are various software development life cycle models defined and designed which are followed during software development process. It aims to be the standard that defines all the tasks required for developing and maintaining software. The life cycle defines infogmation methodology for improving the quality of software and the overall development process.
The SDLC aims to produce a high quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. Requirement analysis is the most important and fundamental stage in SDLC.
The programming code sedurity generated as per DDS during this stage. This is done through.
SRS is the reference for product architects to come out with the best architecture for the product to be developed. A design approach clearly defines all the architectural modules niformation the product along with its communication and data flow representation with the external and third party modules if any.
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 model being used for their project. If the design is performed in a detailed and organized manner, code generation can be accomplished without much hassle.
Sometime product deployment happens in stages as per the organizations. Planning for the quality assurance requirements and identification of the risks associated with the project is also done in the planning stage. Following are the most important and popular SDLC models followed in the industry: Software Requirement Specification document which consists of all the product requirements to be designed and developed during the project life cycle.
The product may first be released in a limited segment and tested in the real business environment UAT- User acceptance testing. Then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment.
A typical Software Development life cycle consists of the following stages: Customer interaction is the backbone of Agile methodology, and open communication with minimum documentation are the typical features of Agile development environment. These models are also referred as “Software Development Process Models”.

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. 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. After the product is released in the market, its maintenance is done for the existing customer base. Agile is the most popular model used in the industry.
This DDS is reviewed by all the important stakeholders and based sceurity various parameters as risk assessment, product robustness, design modularitybudget and time constraintsthe best design approach is selected for the product. Each process model follows a Series of steps unique to its type, in order to ensure success in process of software development.
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. The software development life cycle SDLC is a framework defining tasks performed at each step in the software development process. It consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. However this stage refers to the testing only stage of the product where products defects are reported, tracked, ssecurity and retested, until the product reaches the quality standards defined in the SRS.
Based on informaton requirements specified in SRS, usually more than one design approach for the product architecture is proposed and documented in a DDS – Design Document Specification.
It is performed by the senior members of ibformation team with inputs from the customer, the sales department, market surveys and domain experts in the industry.
This information is then used to plan the basic project approach and to conduct product feasibility study in the economical, operational, and technical areas. Sequential means that the next phase can start only after the completion of first phase.
Big Bang model is a random approach to Software development and is suitable for small or academic projects. Itt2042 tutorial also gives you an insight into the pros and cons and the practical applications of the SDLC models discussed.
The outcome of the technical feasibility study is to define the inormation technical approaches that can be followed to implement the project successfully with minimum risks. The internal design of all the modules of the proposed architecture should be clearly defined with the minutest of the details in DDS.
It is also called as Software development process. SDLC is a process followed for a software project, within a software organization.
In this stage of SDLC the actual development starts and the product is built. Once the product is tested and ready to be deployed it is released formally in the appropriate market. Agile introduces the concept of fast delivery to customers using prototype approach.
