2SYSTEM ANALYSIS OF CRM
Part A
Task 1: Report
Spiral Model: This particular model is mainly considered to be perfect combination of
both iterative and waterfall model. It is inclusive of both controlled processing and systematic
progress of waterfall model in the iterative model (Sharma, Sabharwal and Sibal, 2014). This
particular process comes up with four kinds of phases. The four phases consist of stages like
identification, design, construction, evaluation and lastly proper analysis of risk. Identification
stage mainly initiate by proper collection of various requirements of business. The design mainly
deals with designing the various phase of the system. The design of software is mainly inclusive
of following things like logical, architectural and physical design. The actual software is mainly
developed in construct phase. Developed software is mainly created by taking into consideration
the requirements and design (Kazim, 2017). Analysis of risk is all about identification,
monitoring, analysis and estimation of various kinds of risk in the given project.
Benefits: There are large number of benefits of this model like:
 Changing of requirement is mainly supported by this particular model.
 Making use of prototypes is considered to be very positive thing about this model.
This particular model is considered to be useful in development of huge quantity
of prototypes.
 Process or method of requirement analysis is mainly done accurately and very
finely.
 Application of user can be easily seen in the earlier stage.
Drawbacks: There are several kinds of drawbacks of this Model like:

3SYSTEM ANALYSIS OF CRM
 Managing of the given task is considered to be very complex in nature.
 In some of the cases it can be easily encountered that project manager may fail to
understand the fact that the whole project has ended.
 Number of spirals which are used in the project may fail to easily handle by the
project manager as the given quantity have increased over the period of time.
 This particular model is not considering to be suitable for low risk kind of
projects.
Agile Model: It is considered to be as one of the popular model of SDLC as it allows
various project manager to handle projects in different ways. In agile Model, various kinds of
modification can be done about the current phase so this model can easily work with the given
requirement. Various kinds of activities in agile model are mainly put within the given time
frame so that this particular model can easily work at each and every stage of the given project
(Fuggetta and Di Nitto, 2014). Agile model comes up iterative approach which is used for
delivering application unit at each and every unit after the completion of given project at the end
of each and every iteration. Each unit of software is considered to be modified version of
previous model. The feedback of the various users comes up with great impact on the given
model. This model is considered to be adaptive in nature of SDLC in comparing to waterfall
model which is considered to be predictive in nature.
Benefits: Agile model comes up with large number of benefits like:
 This model is considered to be very realistic kind of approach
 This method mainly provides support for cross training along with team work.
 Providing partial solution at beginning is considered to be crucial benefit
 This particular kind of model does not require any kind of extensive planning

4SYSTEM ANALYSIS OF CRM
 This model generally requires or needs minimum amount of sources.
 Development of functionality is mainly done on quickly basis.
 It is very easy to manage the projects
 This particular model is generally considered to be flexible for large number of
developers
Disadvantages: There are many drawbacks of this model like:
 This particular model does not provide support for complex query management.
 The potentiality of taking of risk which is associated with sustainability,
maintenance and extensibility is mainly considered to be of much higher value.
RAD Model: RAD stands for rapid action development which is totally based on various
kinds of ideas or logic related to iteration and prototyping. This model does not require any kind
of specific planning (Alshamrani and Bahattab, 2015). This particular model focus on the fact
that existing kind of prototypes allow better kind of gathering of requirements of various
customers. By the help of testing of various kinds of prototypes, the project manager can easily
have some better idea regarding the progress of given projects. A prototype can be easily stated
as a working model which is considered to be practically to any part of any given item. In RAD
model, various kinds of utilitarian modules are made as prototypes are mainly incorporated for
making the whole thing conveyance. As there no kind of gritty preplanning so it makes the
whole much simpler for fusing the given progressions which mainly works under the
advancement procedure. RAD venture is mainly considered to be iterative and kinds of iterative
model. It can be having little groups which involves designers, space specialist, agents for client
and other kind of IT assets working in the logical on the part or even prototype. The most

5SYSTEM ANALYSIS OF CRM
important part is this particular model is to mainly ensure the fact that this model is fruitful so
ensuring the fact that the prototypes are created for reusability.
Advantages: There are large number of advantages of making use of this RAD model
like
 Progress of the given report can be easily measureable in nature
 Time for development is considered to be much lesser in comparison to other kinds of
models.
 This particular model is mainly concentrated on the feedback of large number of users.
Drawbacks:
 The dependency on this particular kind of modelling can easily make the whole project
more vulnerable.
 Management of project is considered to be very complex in nature.
Recommendation
According to the given case study, it is much suitable for stating the model which is
considered to be less complex for management and benefit of scope for creep handling which is
the best kind of option available. For the development of software for AFD, the best kind of
software provided is Agile. This particular model will allow project for development of team
which can be used for developing system as per the requirement of users.

Re: Implementing User Centred Design and Human Computer Interaction
Respected Sir,
The ultimate goal of the memorandum is to easily provide a basic kind of idea regarding
the implementation of User Centred Design and HCI (Human Computer Interaction) which can
be easily used for the purpose proposed application of CRM application in an organization. User
centred Design is mainly concentrated on the various users of the system. The design is not for
usability of any kind of application. The designer can easily understand the basic idea regarding
the usage of system. They have come up with specific kind of user requirement and design
solution which is mainly analyzing against the requirements for various kinds of identification.
HCI that is Human computer interaction is all about studying the various identity of
interaction of users with any kind of system. HCI mainly allows various kinds of designers to
specify how various kinds of users can access the function of the system. They come up with
various kinds of principles based on Human computer design.
UCD principles are mainly applied for proposing of CRM which is taken to be some kind
of basic thought for being powerful. AFD CRM is designed in such a way that various kinds of
users of the given system and kinds of task they will perform. Consistency in the given task
process and behavior of system will make a great kind of advantage.

7SYSTEM ANALYSIS OF CRM
Plan for UCD based HCI for various application of CRM is manly done during the
presence of project manager. In the beginning phase the project manager and various kinds of
analyst will have to identify various kinds of requirements related to business and system.
