Definition. Business applications are information systems that support the routine and strategic functions of an organisation, such as accounting, sales, production, HR and inventory.

Key points.

Functional systems serve one department, for example payroll for HR or billing for finance.
Transaction processing systems record daily events such as sales and payments, and they feed every higher-level system.
Management information systems and DSS turn that transaction data into reports and decision support for managers.
Enterprise-wide applications such as ERP, CRM and SCM integrate the functions so that all departments share one set of data.

Decision Support Systems (DSS): characteristics, problem analysis v/s decision making

Definition. <mark>A Decision Support System is an interactive, computer-based system that helps managers use data and models to solve semi-structured and unstructured problems.</mark>

Key points.

A DSS has three components: a database of internal and external data, a model base of analytical and what-if models, and a user interface (dialogue system) for the manager.
Its characteristics are that it is interactive, flexible, supports judgement rather than replacing it, and handles semi-structured problems.
Problem analysis studies the problem, its causes and data, while decision making chooses the best alternative; the DSS supports both stages.
For control, the DSS compares actual results with plans and shows the variances so the manager can correct them; for decisions, it runs what-if scenarios on alternatives, for example the effect of a price cut on profit.

Asked: [7 marks] (Nov 2022) Explain decision support system for control and decision making.

DSS applications in E enterprise

Definition. DSS in an e-enterprise applies decision support to internet-based business, using online and real-time data to guide managers.

Key points.

Web-based DSS is reached through a browser, so managers in different places use the same models and data.
Typical uses are demand forecasting, dynamic pricing, customer analysis and supply-chain planning.
Data warehouses and data mining supply the large volumes of online data that the models analyse.

Knowledge Management System and Knowledge Based Expert System

Definition. A Knowledge Management System captures, stores, shares and applies an organisation's knowledge, while a Knowledge Based Expert System is software that copies the reasoning of a human expert in a narrow domain.

Key points.

Knowledge is of two kinds: explicit knowledge is documented, and tacit knowledge lives in people's experience.
A KMS works through creating, storing, sharing and applying knowledge, for example a repository of past project reports.
An expert system has a knowledge base of facts and rules, an inference engine that reasons over them, and a user interface.
Expert systems are used in medical diagnosis and loan approval; their limit is that they work only in a narrow domain.

Enterprise Model System and E-Business

Definition. An enterprise model is a structured representation of the organisation's processes, data, resources and rules, and e-business is the conduct of all business activities over electronic networks.

Key points.

The enterprise model gives one common view of the business, which is used to design integrated systems.
E-business is wider than e-commerce because it includes internal processes such as procurement, production and customer service as well as selling.
The main e-business models are B2B, B2C, C2C and B2G.
Its benefits are lower cost, wider reach and faster service.

ERP systems

Definition. <mark>Enterprise Resource Planning (ERP) is an integrated software package that connects all functions of an organisation, such as finance, HR, production, sales and inventory, on one common database.</mark>

Key points.

ERP is modular, so a company buys only the modules it needs, such as finance, HR, manufacturing, sales, inventory and purchase.
All modules read and write one central database, so data is entered once and never duplicated.
Integration means an event in one module updates the others at once: a sales order reduces inventory and raises a purchase or production request.
Because everyone sees the same real-time data, ERP gives data consistency and better decisions.
ERP improves efficiency by automating routine work, cutting manual paperwork, lowering inventory and shortening the order cycle.
It improves collaboration because departments share one information source instead of separate files.
Its limits are high cost, long implementation, staff resistance and heavy dependence on the vendor.

Example. A manufacturer that runs SAP gets a customer order, and the system checks stock, triggers production, schedules purchase of raw material and prepares the invoice without re-entering data. Walmart and Tata use ERP to cut stock and delays.

Answer frame. Open with the definition; draw the central-database diagram; then develop points 1-6 in that order; add the example; close with the limits and a line that ERP gives a single integrated view of the enterprise.

Asked: [14 marks] (Nov 2022) Write short note (on any two): a) ERP system b) Model and approaches to system development c) Structure/Architecture of MIS Asked: [7 marks] (Nov 2023) Explain the key role of Enterprise Resource Planning (ERP) systems in improving organizational efficiency and collaboration. Provide examples of their impact.

Pitfall: Options b and c of the 14-mark question belong to Units 3 and 1; choose ERP plus whichever of them you know better.

E-Commerce

Definition. <mark>E-Commerce is the buying and selling of goods and services, and the transfer of money and data, over the internet and electronic networks.</mark>

Key points.

The types are B2B (business to business), B2C (business to consumer), C2C (consumer to consumer) and B2G (business to government).
Its components are the website or app, a product catalogue, a shopping cart, a payment gateway, order processing and logistics, and security.
Applications include online retail such as Amazon and Flipkart, online banking, e-ticketing for railways and airlines, and online auctions such as eBay.
Further applications are e-procurement between firms, digital content such as music and e-books, and online services such as education and cab booking.
Benefits are 24x7 availability, a global market, lower cost, quick comparison and faster transactions.
Limitations are security and fraud risk, no physical inspection of goods, dependence on internet access, and delivery problems.
In modern business it is now a core sales channel and not only an add-on.

Answer frame. Open with the definition; draw a small tree of the types; then develop the applications in points 3-4 with examples; close with benefits and limitations.

Asked: [7 marks] (Nov 2022, Nov 2023) Define E-Commerce. Explain E-commerce application in detail. Write short note on E-commerce.

E-communication

Definition. E-communication is the exchange of information within and outside an organisation through electronic means.

Key points.

The main tools are email, instant messaging, video conferencing, intranet, extranet and social media.
It is fast, cheap and leaves a record, and it removes distance between staff, customers and suppliers.
Its problems are information overload, security and privacy risks, and the loss of personal touch.

Business Process Reengineering

Definition. <mark>Business Process Reengineering (BPR) is the fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in cost, quality, service and speed (Hammer and Champy).</mark>

Key points.

The need arises from competition, changing customer demand, new technology and slow, costly processes.
BPR is radical redesign from scratch, not small incremental change as in continuous improvement.
Its principles are to organise around outcomes and not tasks, let those who use the output do the work, capture data once at the source, and treat dispersed resources as centralised.
The steps are to identify the process to be reengineered, set the objectives, study the existing process, design the new process, implement it, and then monitor it.
Information technology is the main enabler, since it allows automation, parallel work and shared data.
Benefits are lower cost, faster delivery, better quality and higher customer satisfaction.
Challenges are employee resistance, high cost, weak top-management support and the risk of failure.

Example. A bank reengineered loan approval from many sequential desks into one case handler with a shared system, which cut approval from weeks to days.

Answer frame. Open with the definition; draw the step flow as a chain of boxes from identify to monitor; develop points 1-5, then the example; close with benefits and challenges.

Asked: [7 marks] (Nov 2022, Nov 2023) What you understand by business process reengineering describe in detail? Explain the importance of Business Process Reengineering (BPR) in transforming and enhancing organizational efficiency. Provide illustrative examples.

Last-minute revision

DSS = database + model base + user interface, for semi-structured problems.
DSS for control compares actual with plan; for decisions it runs what-if analysis.
Explicit knowledge is documented; tacit knowledge is in people's heads.
Expert system = knowledge base + inference engine + user interface.
E-business is wider than e-commerce and includes internal processes.
ERP = integrated modules on one central database.
ERP gives data consistency, efficiency and collaboration, but costs a lot and takes long to implement.
E-commerce types are B2B, B2C, C2C and B2G.
E-commerce parts are website, catalogue, cart, payment gateway and logistics.
BPR = fundamental rethinking and radical redesign of processes (Hammer and Champy).
BPR steps: identify, objectives, study, design, implement, monitor.

Memory hooks
