TELEHEALTH PROJECT
Introduction
This report aims to discuss the aspects of the implementation of the solutions of
Telehealth Project. A review of the cloud based solutions along with the advantages and the
disadvantages are provided in this report. The advantages and the disadvantages of the
predictive SDLC approach and the advantages and the disadvantages of the Adaptive SDLC
approach is provided in this approach is provided in this report. Lastly, this report concludes
with an appropriate conclusion for this report.
The telehealth is the project that was introduced for improving the access to quality
healthcare in the rural public hospital or the health service. When the separation of the
professionals of healthcare is done, the communication among them became hard for
delivering the enhanced quality health or the related processes like the education.
Discussion
Non-functional requirements
The telehealth is commonly the use of any technology for delivering the health,
medical and the education connected services and the information.
The critical qualities of the system of the telehealth are the:
 Ease of access to the health experts
 Time saving for the patients as this methods does not require the regular visit to
the doctor
 Availability of the advice of the specialists
 Reduction of the transport expenses of the patient
User interface for the telehealth: The use of the telehealth is easy for any person. The process
involved in the use of the telehealth project are as follows:

TELEHEALTH PROJECT
Stage 1: Scheduling: With use of the apps of the telehealth, the patients could request the
appointment with their respective doctor and the confirmation of the appointment is provided
within minutes.
Stage 2: records: The sending of the records of the patients is done using email or the app and
the storing is done in a file
Stage 3: Connect for any call: The patient gets the call from the appointed doctor at the
specified time.
Stage 4: Diagnosis: Analysis of the condition of the patient is done on the basis of the records
and the conversation with patient.
Stage 5: Prescribing: The prescription is sent to the patient by the doctor.
Stage 6: Payment: The payment is done when all the above process is complete.
System constraints
Technical infrastructure: The technical infrastructure is necessary for the successful
implementation of the health project and because of the fact that it is connected to the
internet, the patients require an internet service.
Funding: This aspect is necessary for the costs of the infrastructure and the payments
to the people associated to the staff of telehealth.
Usability: In the recent years, the utilisation of the telehealth technologies is swiftly
increasing due to the feature of the service of being minimal time consuming and hugely cost
saving and the availability of several specialists is there on one single platform.
Reliability: The increase in the projects of the telehealth displays the dependence of
the people on the health services based on the technology.

TELEHEALTH PROJECT
Performance: Activities of the telehealth are progressively rising with the awareness
among the public.
Security: The telehealth consists of their appropriate technical term and the
management of the data is done in secure methods for restricting the access to any data by
unauthorised users.
Advantages and disadvantages of cloud
The environment of cloud that is to be deployed for the telehealth project is the SaaS
environment. This service provides the capability of renting the software and the
infrastructure for enabling the effective cloud storage for the project.
Discussing about the advantages of the SaaS environment of the cloud computing, the
following benefits are presented with the focus on some of the points for the telehealth
project:
Advantages
Simplified access to the information: As soon as the registration of the users is done
in the cloud environment, the access to the information on the cloud is provided to them from
anywhere where there is an internet connection.
Recovery and backup: As all the data has been stored in cloud, the backup and the
restoring of the same is comparatively easier than the storing of the same on any physical
device. Moreover, most of the service providers of cloud are commonly able to handle the
responsibility of information recovery.
Integrated automation of software: In the technology of cloud, the integration of the
software is commonly a feature that is done automatically by the cloud. This denotes that no
extra efforts are required by the cloud users to integrate the customised application according

5
TELEHEALTH PROJECT
to their own preferences (Almorsy, Grundy & Ibrahim, 2014). This aspect commonly takes
care on its own.
Cost efficient: The technology of cloud computing is considered to be the most cost
efficient solution for using, maintaining and upgrading (Stavrinides & Karatza, 2016). The
cloud on other hand, could be available for the companies at significantly cheaper rate and
therefore, it can significantly lower all the IT expenses of the company. Moreover, there are
many scalable options that are available like the pay-as-you-go, one-time-payment and
several other options of scalability that are available for the companies that makes the
solution of cloud significantly reasonable. It can also be perceived that the solutions of cloud
lowers cost for the smaller firms that intends to apply the techniques that are compute
intensive.
Disadvantages of the cloud services
Even though the cloud provides several advantages to the organisations, there are
several disadvantages of the cloud implementation in any organisation. Some of the
disadvantages of the cloud technology are:
Cloud security: The major issue of the cloud is represented by the security. Prior the
adoption of the technology, the beneficiaries must have the idea of the dangers that they
might face with the surrendering of all the sensitive information of the business to any third-
party provider of cloud services (Kavis, 2014). Therefore, the businesses must ensure that the
right solution of cloud have been chosen by them from any reliable provider of this service
who would ensure the security of the information.
Technological issues: It has been commonly observed that the cloud storage
sometimes face serious malfunction and it leads to the temporary shutdown of the services for
the organisations (Dillon & Vossen, 2014). The businesses must have the proper means for

6
TELEHEALTH PROJECT
handling such situations the outages and any other technical issues can damage the business
process of the organisation. The best providers of cloud can face this issue even though
maintaining the cloud service at significant high functions.
Susceptible to attack: The information storage cloud could create significant
vulnerability for the companies to any external threat and any hack attacks and hence it raises
the issue of the theft of the sensitive data.
Advantages and disadvantages of SDLC approach
Adaptive approach:
Adaptive software offers the opportunity of the extensive engagement of the
stakeholders prior the start of the project, during the project and after each stage of the project
life (Kumar, Zadgaonkar & Shukla, 2013). With this engagement, the approach offers the
higher collaboration degree with the clients and with the team of development as it includes
the comprehensive interaction among team and client in each stage. Some of the benefits and
the risks of adaptive SDLC approach of the project are provided in this discussion.
Advantages of adaptive SDLC
Easy delivery is allowed by the Adaptive SDLC: Because of the comprehensive
involvement of the clients prior the project, during and each of the stage of the development
of the software, it leads to the swift development of the process that provides early delivery
of project (Gupta et al., 2018). As the business value is mainly focussed in this approach,
when the realisation of the significant value is done, and the intended satisfaction level of the
client is achieved then the delivery of the project is done earlier than the intended date.
Transparency is allowed by the adaptive SDLC: This approach consists of the
working together by each team in every stage of the project (Sahu, Shree & Kumar, 2014).
Any explanation can be provided by the developers explaining the status of the project to the

7
TELEHEALTH PROJECT
respective clients prior the start of the project, during and also after each of the stage and this
providers the clients with an abstract view of the expectation and it provides the clients with
the opportunity of sharing the opinions with the team of development.
Disadvantages of Adaptive SDLC
The integration of the testing in the adaptive SDLC is done all through the lifecycle.
The testing at each of the stage delivers the products with enhanced quality but it also raises
the project cost in the future (Batra & Barua, 2013). It has been discovered from the studies
that the extensive testing is one of the reason for failure of project. The cost of test phases
that are frequent and long could increase the overrun of the project and then it results in the
project failure.
Extensive involvement of the users is required in the Adaptive SDLC and it consumes
most of the time of the representative of the user and the complete commitment in the project
lifetime. Most of the time of the user agent leads to wastage as in several cases it has been
observed that the engagement of the users is mostly in the sessions of the testing and reviews
and then they are disengaged in the sessions of development.
Advantages of predictive SDLC
The easy and simplified prediction of the timelines and the budget is provided in the
SDLC approach. As an idea of the end result is available and the visualisation of the final
product is done in the stage of initiation of software development, the predictive SDLC
creates an easy understanding for the team to develop the expected budget and the expected
timeframe required for completing the project.
The understanding and the analysis of the predictive SDLC is simple and easy. This
methodology consists of the pre-defined stages that are followed from initiation to
deployment of the software. The steps that are laid down and provision of the methods by

8
TELEHEALTH PROJECT
which the steps are followed allows the developers to provide the developed software in the
timeframe and within the specified budget.
Disadvantages of Predictive SDLC
The usability of the predictive SDLC is not so much for any complex projects that are
object oriented. This use of this methodology is mostly in the smaller projects where the
defining of all the requirement is done in initial stages and the expected outcome is
determined at the stage of project initiation. This methodology is not appropriate for the
projects where the defining of all the requirements is not done or they might be at the risk of
alteration with respect to time. The application of this method is not done for the long and the
currently running projects because of the firmly defined stages and the rigidity.
In the predictive SDLC, the production of no working software is done till the late
phases of software development. Any working of the software product could be generated at
the last stage of the process of software development. The reviews and the testing is executed
only at the late stages of lifecycle model. In several situations, any additional requirement is
identified that was not required in the development phase, and it makes the efforts that are put
in the complete process as null and it is wasted as the repetition of the whole process is done
for accommodating the new requirement.

Recommended SDLC for the Telehealth project
The recommended SDLC for the project is the adaptive SDLC as the project would be
exploited by several users and the environment of the SDLC, the extensive involvement of
the user is done prior, during and each of the step in development. The completeness of all
the requirements of the user is essential for the telehealth project and this would be possible
with the utilisation of the adaptive SDLC.
Conclusion
Therefore, it can be concluded that the best cloud based environment for the telehealth
project is the SaaS based solution as it provides the extended security measures and it
provides comprehensive scalability. The telehealth is the project that was introduced for
