one of the basic notions of the software construction — is the software development life cycle model. existek is a custom software development company helping our customers to solve their business challenges with best in its class software. each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product. in the second phase of the software development life cycle, the developers are actually designing the architecture. also, here are defined the technologies used in the project, team load, limitations, time frames, and budget. after the requirements approved, the process goes to the next stage — actual development.

all the code flaws missed during the software development are detected here, documented, and passed back to the developers to fix. moreover, the update of selected components is included in this phase, to make sure, that the software is up-to-date and is invulnerable to a security breach. the sdlc models diversity is predetermined by the wide number of product types — starting with a simple website to complex medical software. the most used, popular and important sdlc models are given below: during the years of the sdlc evolution, different models were developed from the basic cascade model to meet a huge variety of software development requirements and expectations. download “2020 global custom software development rates” to get a comprehensive analysis of the pricing in the three most popular onshore and offshore outsourcing locations. existek is a custom software development company helping our customers to solve their business challenges with best in its class software.

agile methodology is a software development model that encourages the continuous iteration of development and testing in the entire software development lifecycle of the project. so, we are in need of a better approach to developing the software. where, stakeholders design the system and architecture of the software and the development process. after the waterfall model, we got another incremental and iterative based software development model called the spiral model.

individuals and interactions over processes and tools – people, process and tools and the key players of the software development process. working software over comprehensive documentation – in waterfall and spiral model of software development encourages the comprehensive documentation. so, the agile enforces the adaptation and effort to add the changes at any time or phase of the software development process. by comparing the advantages and disadvantages of various software development models and after the comprehensive debate over agile vs waterfall vs spiral model, we can easily say that agile is better among them. enroll now for aws certified devops engineer training by edureka and increase your chances to get hired by top tech companies enroll now for google cloud certification training – cloud architect by edureka and increase your chances to get hired by top tech companies enroll now for big data hadoop certification training by edureka and increase your chances to get hired by top tech companies enroll now for itil foundation certification training by edureka and increase your chances to get hired by top tech companies
