Want this question answered?
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 .
There are many differences exists between waterfall model and spiral model. In waterfall model if any sudden change takes place in the project, then its very hard to fix the issue. Wherein spiral model we can change according to our requirement.
spiral model is iterative model hence its easy to implement it .
The spiral model is called a meta model since it encloses all other life cycle model.
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.

Spiral model was developed by Dr. Barry Boehm . This model was mainly used to evaluate and resolve risks in the software project.

we use this model when user is not sure of project need.....when risk and cost evaluation is important for project .........and when project has complex requirement or new product line is introduce...
spiral model is just like incremental model but in spiral emphasize is on risk analysis.
The win-win spiral approach is very similar to the spiral model in that it is simply an extension of the spiral model. In the win-win model approach, everyone discusses things together to figure out what should go into the new version of the software.
