This is a highly-disciplined model and the next phase starts only after completion of the previous phase. Easy to manage and no formal procedure are required. Begin with a preliminary analysis, propose alternative solutions, describe costs and benefits, and submit a preliminary plan with recommendations. It is an ideal model for the product where requirements are not well understood and the final release date is not given.

As the software evolves through successive cycles, tests must be repeated and extended to verify each version of the software. Analyze and describe the costs and benefits of implementing the proposed changes. Particular emphasis is given to proper preservation and archiving of data processed by the previous system.

The development process can only continue once management approves of the recommendations from the feasibility study. Spiral Model Application The Spiral Model is widely used in the software industry as it is in sync with the natural development process of any product, i. Find solutions to the shortcomings described in step two and prepare the specifications using any specific user proposals. The following illustration is a representation of the Spiral Model, listing the activities in each phase.

This is aEasy to manage and

Then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment. Management complexity is more. In this phase, plans are developed for discontinuing the use of system information, hardware, and software and making the transition to a new system. This phase also includes understanding the system requirements by continuous communication between the customer and the system analyst.
