Answer 2

Answer:

“Spiral model” is called as “meta model” because it comprises of other software development life cycles. Spiral model is a “risk driven process” model and hence risk handling is by default inherited in it. Depending upon the risk factors, it suggests what type of life cycle – incremental, waterfall, prototype, etc., needs to be implemented. It is suitable for complex development projects that are high risk prone. Compared to other life cycle models, this is considered to be the most complex one.
