1. This methodology is costly to implement
2. Not suitable for small organizations

#6. Spiral Model:

Being a highly sophisticated design, it is meant to reduce the early risks in the project.

As per the process going by, the developers initiate on a smaller level and explore the included risks in it.

Further to this, the developers are intended towards crafting a plan for iterating of the spiral.

The accomplishment of any Spiral Lifecycle model is based on consistent, observant, and conversant management of the project.

Pros:

1. Risk factors are considerably reduced
2. Excellent for large and complex projects
3. Allows for additional functionality later
4. Suitable for highly risky projects with varied business needs

Cons:

1. Costly model in software development
2. Failure in risk analysis phase may damage the whole project
3. Not appropriate for low-risk projects
4. Might get continued and never finish

#7. Extreme Programing Methodology:

As an agile software engineering methodology, extreme programming methodology is presently known as XP methodology.

It is chiefly used for crafting software within a very unbalanced atmosphere.

It enables greater tractability within the modelling procedure.

The foremost aim of this XP model is to reduce the cost of software essentialities.

It is fairly mutual in the XP model that the price of altering the requirements on future stage in the project can be really whooping.

Pros:

1. It lays focus on customer involvement
2. Establishes rational plans and schedules
3. Developers are exceptionally committed to the project
4. Equipped with modernistic methods for quality software

Cons:

1. Effectiveness depends on the people involved
2. Requires frequent meeting for development raising total costs
3. Necessitates for excessive development changes
4. Exact possibilities and future outcomes are really unknown

#8. Feature Driven Development:

Being an iterative methodology for software development, it is aimed at serving a large number of teams working on a project based on object-oriented technology.

This sort of model is decent for companies that are passing on from a phase-based method to an iterative approach.

It is already known as a FDD methodology and is highly functionable and creative enough to deal with varied complexities.

Pros:

1. Moves bigger projects with continuous success
2. Easiest 5 procedures bring outcome in a better manner
3. Built on pre-set standards of software development, it is programmed for easy development

Cons:

1. Not suitable for smaller projects and single developer
2. Highly dependable on the leading developers, necessitating for the complete structure
3. No written document provided to software owner

#9. Joint Application Development Methodology:

The Joint Application Development Methodology is a requirements-classification and user-interface expansion approach that necessitates for the end-users, clients and developers attend a powerful off-site conference to accentuate and confirm software system.

This methodology serves towards including the client in the design and expansion of an application.
