INTRODUCTION
For the purpose of carrying out business in an effective manner, it is quite vital for the
organizations to assimilate information precisely. Information plays a crucial role in good
decision making and if it is not managed adequately, the outcomes are unexpected. The
current research also deals with evaluating the manner in which information systems helps
the management in taking important decisions at varied levels within the organization. The
organization chosen for the current research study is Hyperlink InfoSystem which is one of
the leading mobile application development company of UK. Further, the research study will
also going to analyse techniques and methods pertaining to the design as well as development
of IT solutions and influence of IT on globalization. The final section will throw light on
risks associated with information system outsourcing.
TASK – 1
Theories and techniques related to design and development of two IT solutions
Microsoft Office
Talking in relation with the Microsoft Office, it is a family of server software as well
as services being developed by Microsoft. The first version of this includes Word, excel,
PowerPoint, however over the years these applications have grown significantly and shared
many new features such as data integration, spell checker and so forth. Office is being
manufactured in different versions based on the different target users and environment. One
of the most utilized version is desktop version which is present for personal computers. It was
started officially in the year 1990 and came out for the utilization with Windows 2.0 before
Office 1.0. The fundamental components of the packages were still present as a different
programs however for MS-DOS (Boland, 2019). Microsoft has re-coded the program number
of times from the past several years in order to make it function on varied operating systems
encompassing disk operating system as well as Macintosh. For the purpose of designing and
development of Microsoft office, the theory and technique of concurrent engineering was
being utilized. It is being referred as a systematic method of integrating, simultaneously
designing of products and related processes such as support and production. Seeking help
through this process, the design process of the software can be improved.
Moodle
Talking in relation with the design and development of Moodle information
technology solutions, it is generally founded on a social constructivism development concept

as well as designing of the course management system. Moodle can be utilized as a
traditional classroom teaching course supplement plus aided. Furthermore, it can be used in
any type of support PHP computer platform installation. The interface of this IT solution is
very simple, compatible, stable performance and simple functioning. In addition to this, it is
developed on the basis of network learning evaluation which is a sub-category of the
education evaluation. Education evaluation further includes there components that is analysis
of the development, value judgement and finally, reference standard (Costello, 2017). It is
specifically accumulating network learning activities from the psychology of the learners and
behaviour of the materials. It evaluates the processing and afterwards as per the teaching
objective of the reservation to the procedure of learning activities. It then results to the
procedure of value judgement. Other than this, Moodle is also being developed on the
principles of pedagogy which is mostly been considered as an approach of teaching, theory
and practice of learning and explains the manner learning is being influenced by different
social, political as well as psychological development of learners.
TASK – 2
DSS (Decision Support System)
It is being referred as an information system which helps the business in making
decisions which needs judgement, series of activities and strength of mind. A decision
support system helps the middle and high level management of the company through
evaluating the large amount of unstructured information and at the same time supports in
gathering information which can help in solving issues and decision making. Furthermore, a
DSS can be powered by human and automatic or combination of both. For example,
Hyperlink InfoSystem makes sue of decision support system for planning more effective
advertising as well as analysing market plans in contradiction of other things (About Us,
2021).
ESS (Executive Support System)
This is defined as a software being utilized by the organizations involved in the
information concerning business. This software allows the top level management to make
effective decisions in favour of the firm. Executive support system accumulates information
from both internal as well as external sources and support the top management by offering
data on critical activities of the organization. Executive Support System is chiefly concerned
with information pertaining to accounting, scheduling, staffing as well as billing.
Additionally, it also helps the firms in forecasting and planning and make them prepare for
