Why spiral model does not contain maintenance phase?
In spiral model the main emphasis is on the management to evaluate and resolve risks in the software project. There is no maintenance phase in spiral model because instead risk is evaluated .
Why do you think software development is risky?
Not all models of software engineering are risky. The spiral model takes care of risk in every phase.
What ia a prototype?
A prototype is a working example of what something will be e.g. a car or a computer system. It is designed to demonstrate to funding sources or company managers how a project to develop new products will look.
Why do waterfall model fails sometime?
Waterfall model uses sequential design process, in which each phase is tested in level by level like a waterflow from top to bottom. In waterfall model once we come out of the phase, there is no possibility to change something according to the new requirement, once the phase is done then it is just done. Waterfall model is applicable for small projects.
Explain the use of a discovery prototype and an evolutionary prototype?
In a discovery prototype, normally built during the analysis phase, the intuit is to better understand people's needs and not functionality. That what's evolutionary prototype is for. It is deemed to prove capabilities according with its technology to meet the business needs. Two questions must be answered when using the prototyping method: -have we proven the technology is going to perform as expected? -has the customer understood its potential of the new system?

Waterfall model and prototyping model can be accommodated in spiral model?
1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.

What are the similarities between Tyler's model and Wheeler's model?
Definition The Tyler model of curriculum was developed by the American educator Ralph Tyler in the 1940s, while the Wheeler model is a cyclic model of curriculum developed by D. K. Wheeler in 1967.Phases Tyler’s model has four main components: objectives, selection of learning experiences, organization of learning experiences, and evaluation. Wheeler’s model, on the other hand, has five phases: aims, goals, and objectives; learning experiences; selection of content; organization and integration of learning experiences and content; and evaluation. Evaluation Although both models have an evaluation phase, in Tyler’s model, evaluation is terminal since it is the last phase in a linear model, but in the Wheeler model, evaluation is not terminal. However, in the Wheeler model, the feedback from the evaluation phase is fed back into objectives and goals. Content and learning experience In the Tyler model, there is no separate component for “content” while in the Wheeler model, content is separated from the learning experiences from which it’s developed. The key difference between the Tyler and Wheeler models of curriculum is that the Tyler model fundamentally comprises four concepts and is a linear model adapted for curriculum development, whereas the Wheeler model comprises five theories and was developed as a cyclical model.
Who made the German 88 flak gun?
The German Krupp company developed some new gun designs after WW1 in partnership with Bofors of Sweden. The original design that led to the 88 was a 75 mm model. During the prototype phase, the army asked for a gun with considerably greater capability than the 75. The designers started over, using another common German calibre, 88 mm.

How does alpha differ from beta when talking about a video game?
Basically alpha is a prototype stage of the game and beta is like a phase of testing.

The response plan is developed in which phase of emergency planning?
A: Preparedness

Which phase consumes the maximum effort in waterfall model for developing a software product and why?
The testing phase consumes the maximum effort in waterfall model.
How does a young plant developed into a mature plant?
A young plant becomes mature when it enters in to reproductive phase from its vegetative phase.
