In Big bang model the product development process just starts with the required money and efforts as the input, and the output is the software developed product which not gives the guaranty to the customer about the successfully developed the software product as per customer system requirement.īig Bang Model is SDLC model in which no formal development steps and procedure followed and very little planning is required before beginning the project development. Usage of waterfall model is generally in developing parts of larger systems with fixed requirements.The Big Bang model of SDLC ( software development life cycle ) is applicable where we do not follow any specific process and pre proposed sequences of steps to develop of application software. It is costly if the project requirements has chances of frequent changes.Then we have to pause the current stage and make changes to documents and rework current stage to suit the changes. can be discovered at a time while another stage has already been started. In practical, gaps or bugs or errors of any stage like design, requirements etc.It is hard to implement changes at any stage as each stage documented in earlier stage.Waterfall model fits with other engineering process models which is an advantage as software engineering is different from other types engineering.Each stage produces a document thus the whole development process remain documented.The maintenance part continues with system enhancement and along with changes in requirements which might cause new development or changes in system. Software team solves errors or bugs that pop up in this stage. In this stage, the fully functional system goes live for real life usage. Software team locates and solves these issues, if any. Issues are common in this stage, as the software moves from development environment to live. These test goes through all the requirements to make sure everything is in place and operating as expectations. However, the software team now makes integration and system testing. Approved system parts join together to build up the complete system. Integration & System TestingĪt this stage, integration takes place. At the end of this stage, all parts of the system are should be working accurately. Developers implements solutions to issues found in the tests. In this stage, software team tests each unit or module separately to find out if those meets requirements or expectations.

At the end of this stage, the software team will exactly know what they are going to develop, what are the problems, what are the risks and how to manage the risks and how the parts integrates with each other etc. Software team builds the software architecture which will include modules and their relations, databases and their relations. The system design process then, based on the approved project documentation, defines the software and hardware requirements for the project. The next stage starts with this approved document. Secondly, the developers will analyze the given information to create the documentation both for developers and for the clients. Firstly, the clients will provide their necessities along with constraints and flow of work. Members from the software consults with the client and prepares complete service documentation in this stage. Stages of Waterfall model Stages of Waterfall Software Process Model
