Answer 1

Disadvantages of Iterative Model:

Even though, iterative model is extremely beneficial, there are few drawbacks and disadvantages attached to it, such as, each phase of an iteration is rigid with no overlaps. Also, system architecture or design issues may arise because not all requirements are gathered in the beginning of the entire life cycle. Other disadvantages of iterative model are:

• More resources may be required.
• Although cost of change is lesser, but it is not very suitable for changing requirements.
• More management attention is required.
• It is not suitable for smaller projects.
• Highly skilled resources are required for skill analysis.
• Project progress is highly dependent upon the risk analysis phase.
• Defining increments may require definition of the complete system.
