Answer:

Adaptive Life Cycle: Adaptive life cycles (also known as agile methods or change-driven) are projected to ongoing stakeholder contributions and react to the changes of high levels. Adaptive methods are also incremental and iterative, but that iterations are very quick (generally lasts 2 to 4 weeks) and are Oxed in time and cost.

The advantages of the Adaptive life cycle are as follows:

1. The satisfaction of a customer by fast and continuous delivery of the product.

2. The product is delivered regularly (weeks rather than months).

3. In this approach, modification is done at the execution stage.

The disadvantages of the Adaptive life cycle are as follows:

1. In the case of some product deliverables, above all the large ones. it is difficult to assess the effort required at the beginning of the software development life cycle.

2. If the customer is not clear what final product that they want then the wrong project is made.

Predictive Life Cycle: The predictive life cycle is the one where the scope of the project and the time and cost involved in the project are established as early as possible. In a predictive life cycle approach, the project is well defined and the results to be delivered are understood.

The advantages of the Predictive life cycle are as follows:

1. This approach is easy and simple to understand and use.

2. Each phase of the project has specific deliverables and a review process.

3. In this model, phases are completed and processed one at a time.

The disadvantages of the Adaptive life cycle are as follows:

1. It is difficult to change the plan at later stages.

2. The high amount of risk and ambiguity.

3. It is not best suited for long and ongoing projects.
