SYSTEM ANALYSIS AND DESIGN
Introduction
Telehealth project was introduced for the improvement of access to the healthcare in
most of the hospitals and healthcare services, present in the rural areas (Weinstein et al.,
2014). The professionals of healthcare are eventually separated by longer distance and this
makes it extremely tough for any individual to reach out to health experts or hospitals. It is
very common in rural areas that due to the problem in communication with the health experts,
the patients have intense problems in completing their treatments (Phillips et al., 2016). The
project Telehealth was introduced for this particular purpose so that the treatment can be done
without visiting to the hospitals. The idea was to treat the patients with the help of
technology.
This report provides a detailed description on the project of Telehealth. This report
will help in understanding the several non-functional requirements of the project, which
include functionality, usability, reliability, performances and security. The cloud based
solution, including the strengths and weaknesses is also given here. Moreover, the system
development life cycle approach is described with proper details. Relevant recommendation
are also given in the report.
Discussion
1. Non-Functional Requirements of the System
The identification of any critical quality of a system is done by the non-functional
requirements (Chung et al., 2012). FURPS are the non-functional requirements of Telehealth
project. Functionalities, usability, reliability, performances and also security are explained
below.

SYSTEM ANALYSIS AND DESIGN
1.1 Functionality
The most significant requirement for this Telehealth project is the functionality
requirement. This project is responsible for the better treatment of patients, who have a
problem in communication with hospitals due to their place of residence (Chung et al., 2012).
Telehealth project requires a distinct function for the regular updates and easy access to data
from all devices s per the user requirements. The significant requirement for the Telehealth
project is adaptability.
1.2 Usability
This is the second major requirement for the Telehealth project of rural areas. The
major advantage of this project is that it can be easily utilized with perfect effectiveness and
efficiency (Kulkarni et al., 2012). Usability can be defined as the simplicity of learn ability
and utilization of any human made project or object. This project does not consider the
distance between the patient and the health experts or hospitals.
1.3 Reliability
The third major non-functional requirement of the Telehealth project is the reliability.
This particular project is extremely reliable as real health experts or professionals are hired
for the treatment of the patients (Chen & Zhao, 2012). The difference between normal
hospitals and Telehealth is only that the patients do not have to visit to the hospitals for their
treatments and they can be treated by audio or video conferences. This can bring major
changes in the adaption of technology in rural areas and thus improving the entire system of
treatments.
1.4 Performances
Performance is the fourth non-functional requirement for the Telehealth project. This
project has the ability to provide better performance in the medical field than the traditional

4
SYSTEM ANALYSIS AND DESIGN
ways of treatment. The performance of any project is the most important requirement. As
proper and relevant health experts will do the treatment, it is needless to mention that the
performance of the project will be as good as the traditional treatment system.
1.5 Security
Security is the final non-functional requirement for the Telehealth project. Security is
extremely important for this particular project, as it will be dealing with the life of several
patients (Jain & Nandakumar, 2012). The unauthorized access to this project can be very
dangerous for the treatment of the patients. Biometric system would be the best alternative
for the security of Telehealth project, which would eventually prevent every unauthorized
access.
2. Cloud Based Solution
Telehealth project is initiated by a group of health experts for the proper treatment of
patients, who reside in rural areas. This perfect combination of information and
communication technology and medical field would be extremely useful for these patients
(Phillips et al., 2016). It has been observed that the combination of medical field and
information and communication technology can give the best solutions to all the problems of
rural areas. This project will become if they will opt for a cloud based solution. Eventually,
there are four distinct types of clouds, namely, public, private, community and hybrid. The
public cloud is an open cloud, with no limitations and everybody can access data (AlZain et
al., 2012). Private cloud is different from public cloud. The data access is possible only
within a specific group of clients. Community cloud is the third type and the main feature of
this cloud is that a specific group of clients, with similar or same requirements can access the
data. Hybrid cloud is the mixture of any two clouds.

SYSTEM ANALYSIS AND DESIGN
The best solution for the Telehealth project will be the hybrid cloud. As this is the
mixture of any two clouds, it comprises of all the features of those two clouds (Li et al.,
2015). This particular characteristic is extremely beneficial for any project and can bring
success to the project. Hence, hybrid cloud is the best solution for Telehealth project.
2.1 Cloud Environment Strength
Every type of cloud has significant features. Similarly, the types of clouds have
various strengths and weaknesses (Chen & Zhao, 2012). The recommended cloud for
Telehealth is the hybrid cloud. The important strengths of any hybrid cloud are given below:
i) Cost Effectiveness: The most significant advantage of a hybrid cloud is the cost
effectiveness. A typical hybrid cloud is the proper mixture of two other clouds and thus
comprises of all the features of those two clouds (Galibus & Vissia, 2015). However, in spite
of having features of two different clouds, hybrid cloud is extremely cost effective and does
not incur huge cost.
ii) Security: Security is again another important strength of hybrid cloud. Hybrid
cloud is absolutely secured for any kind of data transfer online (Kulkarni et al., 2012). There
is almost zero chance of data loss and unauthorized data access in hybrid cloud.
2.2 Cloud Environment Weakness
The main weaknesses or demerits of a hybrid cloud are given below:
i) Implementation Cost: Hybrid cloud incurs extremely high cost in implementation
and thus small organizations do not have the capability to afford it (Li et al., 2015).
ii) Data Movement: The second disadvantage of hybrid cloud is the data movement.
The continuous movement of data from the public or private clouds to the hybrid cloud
makes the data easily available for any hacker (Li et al., 2013).

3. SDLC Approach
System development life cycle or SDLC approach subdivides the life cycle of any
system into various stages (Balaji & Murugaiyan, 2012). The main advantage of SDLC
approach in any project is that it reduces the complexities of development of the system.
Predictive and adaptive are two types of approaches of SDLC.
3.1 Predictive Approach
This approach refers to the complete life cycle before starting any project. The
predictive approach is applicable only when the schedules of Telehealth project are
absolutely clear (Mahalakshmi & Sundararajan, 2013). The several pros or cons of this
predictive approach are given below:
Pros:
i) Project planning is perfect.
ii) Project scope and project schedule are absolutely clear to each and every member.
iii) Project requirements are properly understood by all members.
iv) Project progress is tracked during the life of the project.
Cons:
i) Changing of the project plan is impossible.
ii) Feedback of the clients cannot be considered.
3.2 Adaptive Approach
This adaptive approach is the exact opposite of predictive approach. Project planning
is not completed before project initiation. Relevant project deliverables are given in all stages

SYSTEM ANALYSIS AND DESIGN
of the project (Mahalakshmi & Sundararajan, 2013). The pros or cons of the adaptive
approach are given below:
Pros:
i) Project plan can be modified in all stages.
ii) Client feedbacks can be considered.
Cons:
i) Incurs huge cost.
ii) Project scope and project schedule are unclear (Balaji & Murugaiyan, 2012).
Hence, the predictive approach would be the best SDLC approach for the Telehealth
project.
Conclusion
Therefore, conclusion can be drawn that, Telehealth is a project that was initiated for
the successful improvement of access to all the healthcares in the healthcare services and
hospitals, present in the rural areas. The experts of healthcare or the doctors, nurses are
unconnected by the longer distance and this specifically becomes difficult for any person to
communicate with the hospitals or health experts. For the communication problem with the
hospitals or health experts, it is extremely common in the rural areas that the patients have
major problems in completion of their treatments. The project Telehealth was initiated for
this specific reason so that the treatment of the patients could be easily done even when the
patients cannot visit the hospitals. The proposal was simple that they can treat the patients by
technology. The above report has described about the FURPS requirements or functionalities,
usability, reliabilities, performance and security of the project. The solution that is based on

cloud is also given here. The cloud environment has various weaknesses and strengths within
it. These weaknesses and strengths can help to select a proper solution for the project.
Furthermore, the SDLC approach is described with the pros and cons of the adaptive and
predictive approaches.
