9. What are the merits of incremental model?

1. The incremental model can be adopted when tere are less number of people involved in the project.

2. Technical risks can be managed with each increment.

3. For a very small time span,at least core product can be delivered to the customer.

10. List the task regions in the Spiral model.

Customer communication – In this region it is suggested to establish customer communication.

Planning – All planning activities are carried out in order to

define resources timeline and other project related activities.

             Risk analysis – The tasks required to calculate technical and

management risks.

Engineering – In this the task region,tasks required to build one or more representations of applications are carried out.

Construct and release – All the necessary tasks required to construct,test,install the applications are conducted.

Customer evaluation – Customer’s feedback is obtained and based on the customer evaluation required tasks are performed and implemented at installation stage.
