INTRODUCTION
Information systems can be defined as the socio technical system which is designed to
collect and process the data in a secure manner. It mainly composed of the task, people, structure
and technology. It is basically the collaborative set of elements for storing and providing the
information and knowledge. It is used to control the performance of the business. It is the
integration of information and networks of hardware and software which work together to filter
ans distribute the data. It turns raw data into useful information for decision making process by
properly organising and analysing of the data (Rainer and Prince, 2021). The following
discussion is based on the McAfee and MS Office software. Discussions are also made on the
DSS, ESS, TPS, MIS and KMS information systems. Concept of globalisation and effects of
information technology on it are also discussed. Discussion on digital infrastructure, advantages
and disadvantages are also made. Report also covers the risks associated with information
systems outsourcing and why is IT infrastructure so critical to digital transformation with proper
conclusion.
Task 1
Describe theories, methods and techniques which relate to the design and development for
McAfee
It is one of the leading international computer security software founded in 1987 and
headquartered in US. It is responsible for the combining of anti virus, anti spyware, firewall and
intrusion prevention technologies. This is done to stop or remove the malicious software. It
covers the new security risks and reduces the high cost of maintaining the outbreaks with
minimum impact on system performance. Key features of the software are such that it provides
maximum defence against malware. It protects proactively from attacks. It is one of the easy and
centralised along with the proper management tool for computer security. Its advantages includes
that it is unbeatable in malware detection and removal. It protects from zero day attacks as well.
It leverages the McAfee global threat intelligence. It manages the security by quarantine the
important and private files. Moreover, it is efficient in enhancing the email scanning (Stair and
Reynolds, 2020).

MS Office
It is one of the leading international server client software founded in 1988 and
headquartered in US. This software specially consist different documents and tools of assorted
formats with variety of functions and features. Microsoft Word is one of the tool which is a text
application used to create contents, letters and many more. It is used for the purpose of
education, personal use and professional as well. Microsoft Excel is an another tool which
consist the spreadsheet containing rows and columns for calculations an using functions for the
same. Microsoft PowerPoint is also one of the tool which consist the slides and presentation view
used in conferences to perform some demonstration though it. Microsoft Outlook is also an
another tool which are used to manage and send emails. Microsoft Access is one of the tool
which is used to record the data in the data bases and process them as per the needs and
requirements (Beynon-Davies, 2019).
Task 2
Explain the systems below with relevant examples
DSS (Decision Support System)
It is a type of information system which supports the businesses in the activities of
decision making. Such as judgement, determination and sequencing of actions. There are three
components of decision support system such as model management system, user interface and
knowledge base. It associated with the different types of DSS such as communication driven,
model driven, knowledge driven, document driven and data driven. Its advantages includes that it
increases the speed and efficiency in the activities of decision making. It collects and analyse the
real time data. It encourages the training to develop the specific skills to implement and run the
DSS software. It is automates the functions such as monotonous managerial process which
means that manager can spent more of its time in the decision making process. Decisions made
with the help of DSS are strategic in nature which focuses on the company's goals and objectives
and align its decision accordingly (Rajaraman, 2018).
