In build to another you need to come

In this report I will be providing
information about different types of project methodologies and the similarities
and differences between each , furthermore I will be stating  what project type it will be useful for, (big
or small) this will serve useful for individuals who are trainee application
developers.

Incremental development shares many
similarities with the waterfall model; this is in terms of being very simple
and easy to use.

 

Inside the incremental, project requirements
are collated. After this the project requirements are divided into different
modules within the project. After this the developed modules are combined with
other modules that have also been developed.

 

Iterative Development

 Iterative development is a way of breaking
down a specific part of the application; after this is done any specific issues
that have been identified can be solved at that particular phase, an example of
this will be in the testing phase.

 

Incremental Development and Iterative
Development

 

Incremental software development and the
iterative development is a method of software development that is modeled and
based around the gradual increase of features within the system.

 

The incremental development model  and the iterative
development model is used when the requirements of the system is clearly
defined and outlined so models such as prototypes when used in the model will
be fairly accurate towards their target base . It should also be used when
there is a need to get the product to the market early.

 

The main benefit of this is to maintain
control and stability with the software whilst continuously developing it.

 

Incremental and Iterative Development and what is the
difference?

 

Iterative Model of development is
where we rehearse through the idea and keep improving it this is done through a
cynical process so that it is done to outline as we rehearse through numerous
versions. As you move from one build to another you need to come to a
conclusion based on the feedback received between these models on what is the
better build and what needs to be discarded.

An Incremental model is where you
build the solution in parts but at the end of each phase. This solution is not
implemented however until the final stage of the software development, this is
due to the fact it follows the same principle in terms of the waterfall model:

Design, Implementation,
Testing/Verification and Maintenance.

 

Incremental Development Iterative and Continuous
Integration 

Similarly to Continuous integration
Incremental development is also beneficial for a variety of projects. This is
due to the fact it shares the same advantage as continuous integration it is
very easy for the project manager to test and debug as the model is a small iteration,
this means it can be easily identified amongst other phases that may be within
the model.

 

Incremental development is done in bits
therefore it is a slower process, to reach the final stages of development
compared to that of the continuous integration model. This is evident as the
continuous Integration model focuses on finishing tasks systematically and
quickly compared to the incremental development model which is done in small
parts.

 

Incremental Development and Rapid Application
Development

 

Similarly to the Rapid Application
development model, risks and shortcomings can be identified earlier on in the
project. This is evident as both model, have a certain stage in which the
project team and manager will carefully assess and evaluate the test phase
before moving onto the next phase.

 

One Difference between the Incremental
Development and Rapid Application development is that the Rapid Application
development model will be that it is planned for short delivery of
implementation and delivery, whereas the Incremental Development model is
developed into a divided set of timelines, known as “Iterations”.

 

Incremental and Spiral Development

Incremental development model and the
Spiral Development model are both similar in terms of the amount of risks and
uncertainty that may occur during the creation of the Application.

 

One difference between the Incremental
development model and the Spiral model is that an incremental model will need
to have a clear and complete definition of the whole system and software before
it can be broken and separated incrementally, this is not the case for spiral development.

 

Incremental and Agile

The Incremental development and agile
model are both similar in terms of identifying and defining a clear requirement
for the product. This is due to customer feedback on earlier builds of the
software that is created using this model.

 

One difference between the Incremental
model and the Agile model is that the Incremental model is easier to interpret
compared to the agile model. This is due to the fact that in the agile model
only senior and experienced programmers are capable of making accurate
decisions inside the development process; this however is not the case for the
incremental model as the quality of programmer does not need to be as high
compared to the agile model.

Incremental model and V model

 

V model and the Incremental are very similar
in terms of having rigid and systematic procedures to advance through the
model.

 

One difference between the v Model and the
Incremental model is that the Incremental model is more adept at analyzing risks;
this will prevent any shortcomings that may arise during the future,
furthermore it will be able to better adapt to requirements that have changed
due to external factors such as the economy

 

What is the Rapid Application Development Model?

 

Rapid Application Development

Rapid application development is a type of
methodology that uses minimal planning. This is done in consequence of creating
a working model quickly to develop the final product very quickly. Rapid
application development is used when a project, product or system is in need of
being created in a certain period of time. This is usually 2-3 months.

 

 

In addition to this Rapid application
development is used when there is a high availability of designers for modeling
and creating the product, this of course will be need to be accompanied with a
high budget.

 

The Rapid Application Development model
should be used when requirements are clearly identified. In addition to this it
should also be used when there experienced programmers and modelers available
in the project team.

 

Rapid Application Development Model and Waterfall
Model

 

One Similarity between the Rapid
Application Development model and the waterfall model is that

 

One difference between the waterfall model
and the RAD model is that the Waterfall model is generally used for smaller
projects as there is too much of a risk and uncertainty whilst in creation of
the software, as requirements may change, due to external factors such as
economic levels. In addition to this in the waterfall a prototype model is not created
but instead only the final product is given to the client, this however is not
the case for the RAD as uncompleted versions and builds before the final release
are given to the client, this is done so the client can critically assess if
they are meeting the right requirements.
