The Role of Information Systems in Businesses Today and their Challenges
The Role of Info Systems in Business Today
- Wireless technologies (iPhones, e-mail, social media, video conferencing)
- You can do online shopping
- Read E-newspaper
- Conduct online chat/meetings (Skype and Facebook)
What’s new in Management Information Systems (MIS)
- In the technology area there are three interrelated changes
o The emerging mobile digital platform
o The growth of online software as a service
o The growth in cloud computing with more business software runs over the Internet
Why do we need MIS?
- Improve quality of information and information systems
- Connect information system together
- Increase information sustainability – to share info, locally and globally
- Achieve customer and supplier intimacy
- Improve decision making
- Seek competitive advantage
Perspectives of Info Systems
- What is data?
o They are the facts. E.g. 5 foot tall person with brown hair and blue eyes.
o Unstructured (information that doesn’t reside in a traditional row-column database. E.g. Text and
multimedia content)
o Structured (resides in a fixed field within a record or file. E.g. Databases)
- What is information?
o Captures data as information. E.g. Is a picture was taken, the photographs is information, but what you
look like is data.
- DATA IS ALWAYS CORRECT. INFORMATION CAN BE WRONG (E.G. 2 RECORDS)
- What is knowledge?
o Knowledge is what we know
o Data + Information = Knowledge
- What is a system?
o A set of interacting or interdependent components forming an integrated whole (Student enrolment
system, timetabling system, payroll system)
o System function: Input Processing, classifying, arranging, calculating Output (feedback as well)
o Environment: Suppliers, customers, regulatory agencies, stockholders, competitors
- What is an information system?
o A combination of hardware, software, infrastructure and trained personnel organised to facilitate
planning, control, coordination, and decision making in an organisation.
o 6 components that assemble together to provide information and knowledge:
Data
Software
People
Procedure
Telecommunication
Hardware

Information Systems Challenges
- Data could be incorrect
- Information may be incomplete
- People may lack skill, experience, knowledge
- Usability including number of clicks or limited fields
- Procedures with undetailed steps
- Processes with the wrong interface, or too many steps
- Software should be shared and distributed
- Hardware must be reliable, speedy, good time, loading, etc.
- System behavior – input correct data but no correct data output matching
31266_INTRODUCTION TO INFORMATION SYSTEMS– LECTURE 2 – 2ND MARCH
Business Information Management (Organization and Information Systems)
Information Challenges
- Relevancy: How do we find information relevant to our decisions?
- Accessibility: How do organisations make relevant information available to employees and partners through
computer applications, web and email? How is the knowledge used to apply information captured and shared
between employees?
- Security: How do we protect this information from accidental or deliberate threats?
- Value: How can this information help organisation reach their business objectives?
- Legality
Business Management System Impacts
- Workers: Use Transaction Processing Systems – To perform transactions
- Middle Managers: Use Management Information Systems
- Senior Managers: Use Decision Support Systems – Used decision making; Past, present and future predictions
- Executives: Use Executive Information Systems – Primarily, want to foresee the future, long term investments.
E.g., building another office/building. Looks at resources needed, etc.
- As the position gets higher, there is a lower population. As the position gets lower, there is a higher population
Transaction Processing Systems
- Batch processing systems
- Online transaction processing
- Online entry with delayed processing
- Process data generated by, for and about transactions
- Activities: Data collection data editing, data correction, back up and regular maintenance
- Examples: Sale ordering system, customer relationship management, scheduling system, tracking system,
invoicing and billing
Management Information Systems
- Used to analyse strategic and operational activities
- Supply information to management to manage them effectively and efficiently
- Examples: Food and beverage; Front office and back office; Security; Housekeeping; Financial control and
accounting
Operational Management
Operations manager/Self directed teams
Tactical Management

Why Enterprise Resource Planning (ERP)?
- We want to align between information technology, business processes, organisation structure, and strategy
- Real-time monitoring of business functions
- Supports human resource, sale, marketing, distribution
- Business integration and automated data update
- Linkage between all core business processes and easy flow of integration
- Flexibility in business operations and more agility to the company
- Better analysis and planning capabilities
- Critical decision-making
- Competitive advantage
- Use of latest technologies. E.g. Oracle, JD Edwards, PeopleSoft
- Advantage
o Eliminates costly and inflexible legacy systems
o Improved technology infrastructure
o Improved work processes and data access for decision-making
- Disadvantages
o Expense and time
o Radical change
o Integrating with other systems
o One vendor risks

TPS and MIS
Decision Support Systems
- DSS gives direct computer support to managers during the decision making process
- Provides interactive and ad hoc support for the decision making process of managers and other business
professionals:
o Product pricing
o Profitability
o Forecasting and risk analysis systems etc.

31266_INTRODUCTION TO INFORMATION SYSTEMS– LECTURE 2 – 2ND MARCH
- DSS Examples: Medical field; Natural disaster; Real estate investment companies; Universities
- Advantages:
o Improves performance and effectiveness of the user
o Allows faster decision making
o Reduces the time taken to solve problems
o Has been seen to improve collaboration and communication within groups
o Reduces training times because the experience of experts is available within the programs algorithms
o Provides more evidence in support of a decision
o May increase decision-maker satisfaction
o Providing different perspectives to a situation
o Helps automate various business systems
- Disadvantages:
o Too much emphasis/control given to the machines
o May reduce skill in stagg because they become dependent on the computers
o Reduction in efficiency because of information overload
o Shift of responsibility – easy to blame the computer
o Disgruntled employees who feel they are now only doing the clerical work
o False sense of being objective – humans still feed information in and decide how exactly to process it
Business Values in Information Management
- Definition: An informal term that includes all forms of value that determine the health and wellbe ing of the firm
in the long-run
Summary
- Information needs vary, according to magerial level (top, middle, low)
- An info system can be divided into two types:
1. Those that meet the needs of low-level manages
2. Those that meet the needs of middle and upper-level managers
- Low-level managers: Those who run day-to-day operationg and make routine decisions – use operations support
systems, which usually fall into three categories: transaction processing systems, process control systems, and
CAD software
- Mid and upper-level managers may use one of two types of management support system to assist in decision-
making activities:
o Management information systems
o Decision support systems
1. MIS extracts data from a database to compile reports, such as sales analysis, needed for making routine
decisions
2. DSS is an interactive system that collects and integrates data from multiple sources to assist in making non -
routing decisions

Stakeholders
Stakeholder
- Definition: A stakeholder is any individual who can affect or is affected by an organisation, strategy or project.
They can either be:
o Internal or external (Inside the business, or customers)
o Senior or junior
o Power or non-power
- “People or small groups with the power to respond to, negotiate with and change the strategic future of the
organisation” (Eden and Ackermann 1998: 117)
Stakeholder Categories
- Providers Suppliers; partners;
- Users/beneficences Customers; staff
- Governance Audit; steering groups; regulatory; boards
- Influencers Media; trade unions; local interest groups
Stakeholder Theory
- The purpose of a business is to create as much value as possible for stakeholders
- To be successful and sustainable
- Innovation is the way to keep these interests aligned
- Businesses can decline if there is no sale, no profit, no service, no stakeholder
Stakeholder Analysis Matrix (SAM)
- SAM is a method that is used for developing a useful engagement plan
- The aim is to provide a clearer understanding of stakeholders and, as a result, provide insights as to how best to
engage them
- There are many ways to develop the two dimensional matrix. Influence against impact, power against interest of
importance against influence
-

Box C: Stakeholders with high influence, who can
therefore affect the project outcomes, but whose
interests are not necessarily aligned with the overall
goals of the project. They might be financial
administrators, who can exercise considerable
discretion over funding disbursements. This
conclusion implies that these stakeholders may be a
source of significant risk, and they will need careful
monitoring and management.
Box A: Stakeholders appearing to have a high
degree of influence on the project, who are also of
high importance for its success. This implies that the
implementing organisation will need to construct
good working relationships with these stakeholders,
to ensure an effective coalition of support for the
project. Examples might be the senior officials and
politicians or trade unions.
Somewhat

Little/no
influence Box D: Stakeholders in this box, with low influence
on, or importance to the project objectives, may
require limited monitoring or evaluation, but are of
low priority.
Box B: Stakeholders of high importance to the
success of the project, but with low influence. This
implies that they will require special initiatives if
their interests are to be protected. An example may
be traditionally marginalised groups (e.g.
Indigenous people, youth, seniors), who might be
beneficiaries of a new service, but who have little
‘voice’ in its development.
