The model states that the phases are organized in a Linear Order. In other words, the output of one phase becomes the input for the next phase. Various phases have already been explained under a general model of system development. The different phases of the waterfall model are:
Proposal Definition
Feasibility Study
Requirement Analysis
System Design
Coding & Testing
Implementation
System Maintenance
Limitations of the Waterfall Model. 1. The waterfall model assumes that the requirements of a system can be frozen (i.e. baseline) before the design begins. This is possible for systems designed to automate an existing manual system. But for new systems, determining the requirements is difficult, as the user does not even know the requirements. Hence, having unchanging requirements is unrealistic for such projects.
2. Freezing the requirements usually requires choosing the hardware (because it forms a part of the requirements specification). A large project might take a few years to complete. If the hardware is selected early, it is likely that the final software will use a hardware technology on the verge of becoming obsolete. It is a document driven process that requires formal documents at the end of each phase.
3. This model stresses that the requirements should be completely specified before the beginning of the next phase. But it is not possible in all the systems...

Describe about the sdlc for library management system?
Waterfall Model
Which model is suitable for library management system?
waterfall model is suitable for this as the requirements are clear and it is a simple model to develop.
How do you make a waterfall model?
The waterfall Project Management model is a skeleton for system development. It advances consecutively through a succession of phases, preliminarily with system feasibility analysis and concluding up to system release and maintenance.
What are steps to develop waterfall model for railway reservation system?
What are the steps for waterfall model for Railway reservation system
What is system developing?
Im pretty sure that is an API.
What is a waterfall model and describe it?
Waterfall is a system development life cycle
Waterfall model is suitable for which system with justification?
SDLC + Software Prototyping commonly used to develop organisational information systems
Apply waterfall model for railway reservation system?
i need water fall model of railway reservation system.
Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
Three types of systems or system upgrades that may be ideal candidates for a Waterfall Development Model strategy?
The Waterfall Model is the oldest and most well-known SDLC model. The distinctive feature of the Waterfall model is its sequential step-by-step process from requirements analysis to maintenance.
Which SDLC paradigm will be selected in library information system?
The Spiral model seems as an ideal choice here. No other model seems a reasonable alternative to accept as a different answer.This model combines the features of the prototyping & the waterfall model.As library information system for a university is a large project,therefore spiral model is intended for large,complex,expensive & complicated projects.
What are the dimerits of waterfall model?
In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.
