Chapter 4 - Performance Measurement & Control Flashcards
What are the main purposes of information systems?
- Support day to day operations via processing and storing transactions
- Support the managerial activities of planning, decision making, performance management and control
What is a system?
A set of interacting components that operate together to accomplish a purpose
What is an information system?
All systems and procedures involved in the collecting, storage, production and distribution of information
What is information technology?
The equipment used to capture, store, transmit or present information. IT provides a large part of the information systems infrastructure.
What is a system boundary?
A system boundary separates the information system from its environment. Anything outside the system boundary belongs to the systems environment and not the system itself.
What is a management information system (MIS)?
Any system which provides information for use in the decision making at all levels within an organisation
What is an executive information system (EIS)?
They provide board level with summarised information for strategic decisions
What is an expert system?
They provide access and assistance with tax legislation, companies act requirements, etc.
What is a decision support system (DSS)?
They provide information in a flexible format to facilitate “what if” analysis. Often used to assist resource planning at a management/tactical level.
What is an enterprise resource planning system (ERPS)?
An inter grated computer-based system used to manage internal and external resources, including tangible assets, financial resources, materials and Human Resources. It integrates the various business functions into one system and is usually looked after by information management specialists centrally. Management can directly access informations rather than relying on management accounts.
What is a transaction processing system?
Systems that are used to capture all the day-to-day routine transactions within a business, mostly at an operational level.
What is a customer relationship management system (CRM)?
It helps to manage customer data, the business can use it to track and organise its contacts with both existing and potential future clients.
What are the costs of information systems?
- The equipment or software cost
- Implementation/maintenance
- Training costs
- Management and staff time required (opportunity cost)
- Expert knowledge/time required
- System security
- Costs associated with a reduction in the size of the workforce
What are the benefits of information systems?
- Management and staff time saved
- Increased knowledge and expertise
- Improvement in customer experience
- Reduction in other costs (e.g. bad debts)
- Increased quality of information (more likely to be ACCURATE)
What are some examples if privacy and security risks?
Natural disasters, malfunction of computer hardware or software, computer viruses, hackers, electronic eavesdropping or human errors
What are the two types of controls organisations should have in place to safeguard against threats?
- General controls
- Applications controls
What are general controls?
Controls over the IT environment such as access controls, segregation of duties and business continuity planning (e.g. passwords)
What are application controls?
Transaction processing controls automatically performed by the system such as, completeness checks, data validity checks and authorised checks.
What is a LAN?
Local area network
What is a WAN?
Wide area network
What is included within the networked enterprise?
- Internet
- Intranet
- Extranet
- Wireless Technology (WI-FI)
What is the internet?
An electronic communications network that connects computer networks, individual users and organisational computer facilities around the world
What is the intranet?
An internal ‘mini’ internet sines the company’s own networked computers and internet technology.
What is the extranet?
A secure extension of a company’s private intranet. It can be accessed by authorised outsiders.
What is wireless technology?
Technology enabling the linking of devices to networks wherever WI-FI networks are available
What is an open system?
Systems that interact with other systems or the outside environment
What is a closed system?
Systems having relatively little if not no interaction with other systems or the outside environment
What are the internal sources of management information?
- The accounts
- Original budget
- Supplier and customer databases
- Meetings (formal and informal)
- Inventory management systems
- Payroll department/systems
What are the costs of internal sources of management information?
- Direct data capture costs
- Processing costs
- Indirect costs
What is Big Data?
The capturing and processing of data on a vast scale and converting it into information that is able to be utilised by the organisation
What is structured data?
Data stored within defined fields, often with defined lengths, within a defined record, in a file or similar records
What is unstructured data?
Data does not have a prescribed format, it comes in all shapes and sizes and is therefore much more difficult to analyse. Unstructured data may be ‘tagged’ using meta data to make organising and analysis of data easier.
What is metadata?
Other data
What are the characteristics of big data?
- Volume
- Velocity
- Variety
- Veracity
- Value
What are the 5V’sand what do they show?
- Volume (Amount)
- Velocity (Speed)
- Variety (Different formats/systems)
- Veracity (Accuracy)
- Value (The data needs to be able to be analysed and information extractable)
It shows the characteristics of Big Data
What does the DIKW pyramid show?
How we can extract value from big data
What is data?
Raw facts and figures
What is information?
Adding value to raw data
What is knowledge?
Putting information into context
What is wisdom?
Understanding the knowledge and using it in future decisions
What is data analytics?
The processing of big data?
What is data mining?
Analysing data to identify patterns in the data to turn it into useful information
What is predictive analytics?
Using the patters identified from data mining to make predictions
How can you use big data?
- To obtain a competitive advantage
- To identify and/or analyse opportunities to increase revenues
- Build a more complete picture if their customers
- Systems need to ensure information is available and acted upon quickly
What are the uses and benefits of big data, data mining and data analytics for planning?
- Help make budget estimates more accurate by providing missing data
- Provides more reliable information about the impact of factors in the wider environment
What a re the uses and benefits of big data and data analytics for costing?
- Help identify ways of reducing costs through process efficiencies or removing non-value-adding activities
What are the uses and benefits of big data and data analytics for decision making?
- Better decisions can be made due to the new insights into areas
- Information becomes more transparent and more accessible
What are the uses and benefits of big data and data analytics for performance management?
- Provide more detailed and up to date performance management
- Provide a better idea of non-financial performance, indicating better long- term direction and earlier corrective action
What are the challenges and risks of implementing and using big data and data analytics in an organisation?
- Significant costs involved in setting up a system to effectively use big data
- organisations need to adhere to the relevant data protection legislation
- Risk the data may contain data outliers
