Information System and Big Data Analysis Report for Decision Making

This report delves into the realm of information systems and big data analysis, exploring their critical role in organizational decision-making. It begins by defining information systems and illustrating their function in converting raw data into actionable insights, using BJSS as a case study. The report then examines how different information systems, including Transaction Processing Systems, Management Information Systems, and Decision Support Systems, are utilized across various organizational levels within BJSS to facilitate effective decision-making. Furthermore, the report outlines methods, techniques, and theories associated with IT solution design, specifically focusing on the Software Development Life Cycle (SDLC) methodology. It details the various stages of SDLC, from planning and requirement analysis to deployment and maintenance, highlighting their importance in developing tailored IT solutions. The report emphasizes the significance of appropriate information systems and methodologies for achieving enhanced organizational performance and delivering services effectively.

Introduction
Information system refers to software which aids within organisation as well as analysis
of data. Basically, it is accountable for converting raw data within useful information through
which decisions can be made (Logan, 2020). They furnish firms with relevant storage,
computational power, sharing as well as interaction with distinct aspects. To acknowledge this
concept, BJSS is considered that is headquartered in Leeds, UK. They are IT consultant and
provide their customers with customised solution. This report will provide an insight into ways
in IS supports within decisions making and models for designing of solution.
LO3 Illustrate how information system is responsible for supporting management decisions
The scrutiny of complementary networks of software as well as hardware that is utilised
for collection, filtering, processing, creation and its transmission is known as information system.
It is being utilised by organisation to make sure that they are able to carry out their operations as
per desired standard. BJSS has opted to make use of distinct information systems as per
requirements of unlike levels or departments of organisation. They are specified below:
 Transaction Processing System: This is being utilised for maintaining everyday
transactions that are being conducted within organisation. They are used by operational
management levels with a rationale to have answer to daily queries such as how many
software’s have to be developed, what is the inventory left and many others. These can be
answered through TPS in timely manner (Shuman and et. al, 2020). The decisions are
being made via operational managers in highly structured as well as routine manner and
reports that are being produced are detailed. In this context, BJSS can make use of stock
control systems for keeping track of their inventory levels.
 Management information system: Within BJSS, MIS is being utilised via tactical
managers for monitoring current performance of organisation. The outcomes attained
from transaction processing system are used like a input in MIS. It is liable for analysing
input within routine algorithms which are liable for aggregation, making comparison as
well as summarising the outcomes to furnish reports that are being used by tactical
managers for monitoring, controlling and prediction of future performance (Turner,
Weickgenannt and Copeland, 2020). For an instance BJSS can make use of human
1

resource management system for overall welfare of employees, furnishing training to
them, processing salaries and many other essential aspects.
 Decision Support System: They are being used by senior management for building up
non-routine decisions. DSS takes input from TPS as well as external systems and MIS.
The purpose of decision support system is to render solutions for problems which are
unique and can alter regularly. This involves having answer to queries like if production
is doubled that what will be impact on performance of employees, what if new
competitors enter market, etc (Zabukovšek, Tominc and Bobek, 2020). With respect to
BJSS, they can opt for financial planning systems for evaluation of substitute ways for
attainment of objectives and goal. This can be utilised for having an optimised way for
attainment of goals.
The above information systems are being utilised by different hierarchy of employees
within BJSS as per operations they are carrying out. This aids them within formulation of
effectual decision making that will lead them to have enhanced performance.
LO4 Portray methods, techniques and theories associated with design along with formulation of
IT Solutions.
BJSS deals with IT sector means they are liable development of software for their client
along with this they also provides them with consultation, application testing and many others.
The firm has opted for making use of software development lifecycle methodology to make sure
that they are able to accomplish requirements of their potential customers.
SDLC: The process that is being followed for software projects and comprises of detailed
plan for illustrating ways of development, maintenance, replacement and alterations or
improvisation within peculiar software is referred to as SDLC (Logan, 2020). Basically, it
illustrates methodology for improvisation of quality of software and overall process of
development. The various steps that are being used by BJSS with respect to this are illustrated
below:
 Planning & requirement analysis: It is one of the most essential as well as fundamental
stage within SDLC. This is being carried by senior members of BJSS in which they take
input from customers, carry out market surveys, and sales department. The information is
then used for formulation of plan for carrying out feasibility study.

 Defining requirements: When need analysis have been carried out then next step
involves defining requirements of product and then get it approved by their clients
(Shuman and et. al, 2020). For this BJSS makes use of software requirement specification
that is designed during project life cycle.
 Designing product architecture: SRS acts as reference to product architects for coming
up with best designs for software that has to be developed. In design document
specification this involves more than one design so that stakeholder can review them and
on the basis of risks involved, budget, time and modularity the design will be chosen.
Illustration 1: SDLC Stages
 Developing product or software: Here, actual development is initialised and products are
built. On this, on the basis of DDS the programming codes are being generated by
developers of BJSS. In case if designs are performed within in a detailed manner and
code generation will be attained without many complications (SDLC – Overview, 2020).
 Testing the product: This is subset of all stages which are illustrated above, testing
activities are involved within all the stages. In this, product will be tested for reporting,
tracking, fixing and retesting defects that have been incurred until product attains relevant
quality standards that are specified within SRS.
 Deployment in market as well as maintenance: Once the products have been tested as
well as are ready for deployment then they can be released formally by BJSS from
permission of clients (Turner, Weickgenannt and Copeland, 2020). If client want that
3

limited segment must be released and it must be tested within real business environment
then firm needs to go for that. As per the feedback attained further modifications can be
carried out.
Conclusion
From above, it can be concluded that, firm need to make sure that they have relevant
information system as per levels of organisation. This will enable them to deliver their services
as per required standards. For this distinct models like SDLC can be used for designing of
solution to deal with different business aspects.
