Framework related to audit as well as process improvement. Discussion related to recent issues
related to network security and need of business to act on proposals. It should have to
accompanied through proper action plan.
Audit is intelligent as well as critical examination of company books and accounts. By an
independent person auditing one who is qualified for the job with the assistance of statements,
information, papers and comments which received from authorities (Broadhead, 2015). So that,
examiner can confirm authenticity related to financial accounts which prepared for specific

inside control framework for deciding the degree of checking out the audit.
Process improvement include business practice of identifying, analysing as well as
improving existing business processes for optimizing performance, meet best practice standards,
improving qualities and meeting customers expectations (Desimone and Pak, 2017). Procedure
improvement have various names, for example, business process the executives, business process
the board, business process improvement, business process re-designing and constant
improvement process. There are several process improvement techniques which Tesco have to
implement in their working (What is Process Improvement in Organizational Development?,
1

2020). As they can secure their data as well as services with the assistance of it. Explanation of
these are as follows :-
 Kaizen – This advances constant improvement with having solid accentuation on lean
just as coordinated practices. Kaizen strategy of procedure improvement centre around
improving quality, profitability and proficiency by little moves with day to day activities
or corporate culture for foster an environmental which give punishment for any mistake
but focus on that same thing will never happen again (Dimmock, 2016). Thus, with the
assistance of this approach process improvement will take place place in effective manner
and company will be able to conduct their operations effectively.
 5S – This model is a piece of Kaizen just as Lean systems and it represents significant
five stages i.e., sort, sparkle, fix, institutionalize just as support. 5S model give help with
bringing more consistency for method improvement and can likewise institutionalize
process improvement.
 PDCA – It stands for plan, do, check and act as well as this PDCA provide assistance to
company in more efficient while identifying process which need improvement (Inuwa
Napoleon Daniel Usman and Dantong, 2015). For Network manager it is essential to
identify the problem (plan), implement and create solution (do), data evaluation for
effectiveness (Check), after that final result will document and plan will implement if it is
successful (act).
Tesco is facing issue related to security of both data and services. For them it is essential to
implement some better technique which provide them assistance in securing data as well as
services. Thus, company have to implement VOIP technologies in their operations because it
will provide them assistance in security of both data as well as services. Explanation of this are
as follows :-
VOIP (voice over internet protocol) is technology which allow individual to make calls
through broadband internet connection rather than using regular phone line. In addition to this,
some VOIP services allow individual to make call other people who are also using same services
but others allow to call anyone who have telephone number involving long distance, mobile,
local as well as international numbers (VoIP (voice over IP), 2020). Moreover, there are some
VOIP services which work only over computers and also on special phone. Furthermore, it is the
transmission of voice as well as multimedia content on IP networks (internet protocol). Voice
2

over internet protocol use codecs for encapsulate audio in data packets and also transmit packets
across Internet Protocol Network as well as unencapsulate packets within audio on the other end
of connection. There are several type of VOIP which company can implement in their operation
for security of data and services. But for Tesco Business VOI service is most essential as it help
them in security of their data as well as services.
Business VOIP services are designed for serving numerous users as well as traffic within
single account (McCann and Brown, 2018). This services begin at 20 specific phones numbers
and it can scale up to thousand large scale companies. With traditional landlines organisation
face technical as well as cost problem in this VOIP is best technique which provide assistance to
them in sharing information in effective manner with any security issues. In addition to this,
Voice over internet protocol also help in estimating internal and long distance toll charges.
Moreover, VOIP for business comes within two options such as On-Premises as well as cloud
based. Both will provide assistance to Tesco in conducting secure as well as cost effective
communication which traditional landlines will not offer. It involve several services such as
audio and video conferencing interactive voice response, screen sharing, call queues & reports,
automated attendants and many more(Opperman and et. al., 2016). All these mention features are
scalable and Tesco will gain proper and complete technical support in relation to this.
For on-premise VOIP system, company require to buy all the necessary equipments and
place them in office. This entire process of purchasing required things will result in huge capital
cost for business. For PRI circuit or SIP trunking company have to pay monthly charges along
with this, for IT staff who will maintain it, repair as well as upgrade it on regular basis when
required also paid by business firm. In this important thing is that individual have total control
over hardware as their will be proper security of data and services. On the other hand, Cloud
based VOIP system outsource the phone related system to Voice Over Internet Protocol
providers. This simply means that company don't need to purchase any hardware or invest
resources for maintaining the system (Regan, Laschinger and Wong, 2016). VOIP service
provider have to take care of everything because users providing them monthly fees. Within
could based VOIP system it will be easy to remove users easily. But their will be no control over
hardware and company have to rely on for ensuring system reliability and security.
Implementation of VOIP technology will result in several advantages for Tesco
explanation of these are as follows :-

business environment. In this situation VOIP (voice over internet protocol) provide
assistance to business firm in sharing information as well as data in effective manner
without any chances of theft.
 Lower Costs – For every business which can be small or large will focus on considering
such approaches which result in cost saving. By adopting VOIP phone system Tesco can
save cost significantly. For instance, for an business landlines phone system cost $50 per
line every month. This rate is comprises of local calls only in relation to this, VOIP plans
are available for less than $20 per line. Thus, no organisation want to expand huge money
in such practices so for them VOIP (voice over internet protocol) will be effective as it is
not much expensive in comparison of landlines.
 Increase accessibility – For VOIP business accessibility is one of the biggest benefit as
well as major benefit is the cloud based VOIP service that provide capability in which
individual do call from where ever they want. It organisation have appropriate data
connection then they can make as well as receive calls for business (Rhode, 2016). In the
situation when individual is unable to answer call then call will directly make to another
person or voice email will receive.
 Advance features for small and large team – There are some advance features in VOIP
system i.e., auto attendant as well as call transferring. Moreover, it help large scale
organisation in becoming more approachable. In simple term VOIP helps in making best
uses of all the features available. Major advantage which voice over internet protocol
offer over traditional phone system is multi party calling capabilities. In addition to this,
organisation can be large or small but both need separate conference call which enable
several people to join same call.
 Supports multitasking – With traditional phone calls Voice over internet protocol help
company in sharing documents, images as well as also help in doing video call. This will
help in getting more integrated meeting with customers as well as staff members from

any corner of world. Thus, VOIP provide support to Tesco in performing multi task at
same time.
 Increase security – In an organisation security related to phone system security is big
deal because within this demand related to personally identified information never been
asked. These type of security threats can mitigate through VoIP by leveraging the
improvement which has been made within Internet Protocol technology involving
encryption as well as developed personality management (Tribe, 2015).

process improvement is essential for an business firm because it will help them in conducting
their operations more effectively. Apart from this, it is responsibility of companies to secure their
data as well as services because any distribution in this may give wide negative impact on
working of company. As any important data or information of customer may get leak due to this
which is crucial for company.
Moreover, for data and service security VOIP technology is better as it provide assistance
in several manner. Along with this, chances of data and services misuse will also get reduce with
the assistance of Voice over internet protocol. There are several type of VOIP system and for an
organisation business VOIP services are designed for serving numerous users as well as traffic
within single account. This services begin at 20 specific phones numbers and it can scale up to
thousand large scale companies. With traditional landlines organisation face technical as well as
