What are the 5 stages of SDLC?
SDLC (Software Development Life Cycle) Phases, Methodologies, Process, and Models#1) Requirement Gathering and Analysis.#2) Design.#3) Implementation or Coding.#4) Testing.#5) Deployment.#6) Maintenance..
Which one is the most important feature of spiral model?
The most important feature of the spiral model is handling these unknown risks after the project has started. Such risk resolutions are easier done by developing a prototype. The spiral model supports coping up with risks by providing the scope to build a prototype at every phase of the software development.
Which model is suitable for large projects?
The Spiral model is typically used for large projects. It enables development teams to build a highly customized product, and incorporate user feedback early on in the project. Another benefit of this SDLC model is risk management.
Why waterfall model is best?
The advantages of waterfall development are that it allows for departmentalization and control. A schedule can be set with deadlines for each stage of development and a product can proceed through the development process model phases one by one.
What are the 7 phases of SDLC?
Mastering the 7 Stages of the System Development Life CyclePlanning Stage. In any software development project, planning comes first. … Feasibility or Requirements Analysis Stage. … Design and Prototyping Stage. … Software Development Stage. … Software Testing Stage. … Implementation and Integration. … Operations and Maintenance.
What is RAD model?
Definition: The Rapid Application Development (or RAD) model is based on prototyping and iterative model with no (or less) specific planning. In general, RAD approach to software development means putting lesser emphasis on planning tasks and more emphasis on development and coming up with a prototype.

What is spiral model and its advantages and disadvantages?
The spiral model is a traditional agile model which contains 4 different stages:Planning, Risk Analysis, Engineering and Evaluation. … Software projects are constantly passing through phases in iterations,in other words spirals.
Where is spiral model used?
The Spiral Model is widely used in the software industry as it is in sync with the natural development process of any product, i.e. learning with maturity which involves minimum risk for the customer as well as the development firms. When there is a budget constraint and risk evaluation is important.
Is SDLC waterfall or agile?
SDLC is a process whereas Agile is a methodology and they both SDLC vs Agile are very important to be considered where SDLC has different methodologies within it and Agile is one among them. SDLC has different methodologies like Agile, Waterfall, Unified model, V Model, Spiral model etc.
Which model is not suitable for large projects?
The iterative waterfall model is probably the most widely used software development model evolved so far. This model is simple to understand and use. However, this model is suitable only for well-understood problems; it is not suitable for very large projects and for projects that are subject to many risks.
What is the major drawback of using RAD model *?
What is the major drawback of using RAD Model? Explanation: The client may create an unrealistic product vision leading a team to over or under-develop functionality.Also, the specialized & skilled developers are not easily available.
Which process model is best?

What kind of projects are suitable for waterfall model?
Alternatives to the waterfall methodology Due to the strictly linear sequence of the sequentially successive project phases, the waterfall model is suitable – if at all – only for small software projects.
Which tool is use for structured designing?
2. Which tool is use for structured designing ? Explanation: A Structure Chart (SC) in software engineering and organizational theory, is a chart which shows the breakdown of a system to its lowest manageable levels.
What is the waterfall model?
Definition: The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach. It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion.
