- Knowledge Worker
- A Knowledge Worker is a professional who preforms knowledge work
- Knowledge Work
-
Knowledge work is the intellectual activity that is preformed by people upon data, information and knowledge in order to discover business options
Often refered to as decision support - Information System
- is an organized collection of people, information, business processes and information technology, designed to transform inpouts into output in order to achieve a goal
- Business
-
an organization whith one or more people who:
1) decide upone one or more goals to pursue
2) work together to locate and organize resources
3) create processes in order to achieve the desired goal or goals -
Transaction Processing System
(TPS) -
What do they do? Capture and process transactions to make thema vailable to the organization
How does this create business value? Enables a business to efficiently and accurately track the transactions that are at the heart of all business activities- used to support decision making -
Management Information System
(MIS) -
What do they do? Provide timely information to decision-makers through processing and reporting features
How does this create business value? Timely reporting can enable managers to monitor critcal processes and to avoid costly mistakes -
Decision Support System
(DSS) -
What do they do? Provide analytical and visualization tools to support and enhance decision making
How does this create business value? Enables decision-makers to make decisions based on datd and to discover new business opportunities through the use of tools provided by the IS -
Enterprise Resource Planning
(ERP) -
Whst do they do? Integrate and standardize processes and centralize and standardize the storage and management of data
How does this create business value? Can reduce costs associated with duplication of processes and effote. Alos, can reduce decision-making mistakes made due to multiple versions of the same data, information and knowledge - Efficiency
- Doing the thing right- getting the most outpt from a given input
- Effectiveness
- Doing the right thing- the goal or task is appropriate for the given situation
- Productivity
-
Doing the right thing right- achieving an appropriate goal using the least amount of resources
Productivity = Efficiency + Effectiveness - Data
- raw, unorganized facts
- Information
- data that's been processed (organized) so that it is useful to a decision-maker
- Knowledge
- Information plus the human ability to use or correctly apply the information. The "how-to" of knowledge is often based on experience
-
Explicit Knowledge and
Tacit Knowledge -
Knowledge that is readily codified such as the knowledge in text books
Knowledge that is withing you that you gained though experience and through insight and discovver- gives business competitive advantage - Hardware
- is the electronic and mechanical components that you can see and touch
- Software
- is the set of instructions that direct the hardware
- Networking technology
- increase the power of our devices by allowing us to share resources including hardware, software and information
- computer network
-
Is bulit with nodes that can represent computer hardware and the network users, linked together by various types of hardware, software and communication media
Purpose: to share data, information, knowledge and IT resources - LAN and WAN
- Local area Network and Wide area network
- Peer to Peer Architecture
-
Each node is equally responsible for overseeing the functions of the network
The two nodes that are communicating with each other share the responsibility for making sure that the communication is carried out
There are no central computers or severs to make sure that the network is funnctioning correctly - Client/ Server Architecture
-
Each computer or application on the network is either a server or a client
Servers are computer with a lot of processing power that are dedicated to managin network operations and there will usually be more than one type of server on a network - Data Transmission
- is the sending of data usinng electronic signals fomr one computer to another over a communication channel
- Analog
- Uses a continuous electronic signal that you can think of as a wave. Example: dial up internet
- Digital
- used to represent binary values
- Trasmission speed
- relates to how fast a single message can be transmitted between two nodes
- Transmission capacity
- relates to how many messages can be sent over the sonnection simultaneously
- Bandwidth
-
is one way to measure data transmission
measures how much data can be carried during a givent ime period by a communications link and high bandwidth implies higher speed data transmission - Network Protocols
-
Protocols are rules that are agreed-upon so that computers can exchange data
Network protocols are similar int hat they are important in preparing the networked devices for communication with each other - Network Topologies
- the topology (like a street map) of a network defines how the devices that are connected to the network are organized and how they communicate together
- Network Opperating Systems
-
software that manages communication between computers via a network
(Peer to Peer or Client Server) - Network Application Software
-
similar to application software for stand alone personal computers
Any software that incorporates features and capabilities for communicating data over a network - Discovery
- finding of data, informationa nd knowledge relevant to a task, problem, issue, opportunity etc.
- Transformation
- requires you to organize the results from discovery activities
- Analysis
- Thoughtful investigation and examination of the available data, information and knowledge
- Synthesis
- changing idead and parts into solutions and wholes, understanding into plans and actions
- Communication
- sharing your insights, plans and suggestions with others
- decision
- a choice you make about what actions you will take ( or not take) in a given situation and is the outptu of the decision making process
- Structured decisions
- a routine or repetitive decision suggestive of an accepted procedure for making the decision
- Semi-structured decisions
- a decision that combined elements of a structured and unstructured decision (where to live)
- Unstructured Decisions
- a novel, complex or consequential decision that suggests no obvious procedure to deal with the given situation
- CARROTS
- Complete, Accurate, Reliable, Recent, Objective, Timely, Source
- IADD model
- Investigate-Analyze-Decide-Do
- IT Platform
- Consists of hardware, software and network working together
- ubiquity
- existence or apparent existence everywhere at the same time- IT technology has the appearence of ubiguity
- 8
- number of bits in a byte
- System software
-
controls hardware related with a system
Supports the execution of application software - Two main types of system software
- utility software and opperating software
- utility software
- provides additional tools to maintain and service your system i.e disk defragmentation
- operating systems
- coordinates and manages computer resources i.e windows
- Application software
- is a complete, self-contained program or set of programs that is available to the user to perform a specific job
- Business Organizations
-
Organizations that consist of one or more people who
decide upon one or more goals to pursue
work together to locate and organize resources
creat processes in order to chieve the desired goal or goals - A systems view
- organizations transform inputs into goods or services for their customers therby creating business value for themselves
- A value chain view
- organizations can be seen as a chain of activited each or which adds value or supports the addition of value to the firm's goods or services
- A team is
- a small number of people with complementary skills who are committed to a common purpose, performance goasla nad approach for which they hold themselves mutually accountable
- How has God Blessed you life this semester
- SO MANY WAYS!! New Friends, new ministries, revealing to me what I really WANT in my life and constantly challenging me to be a better Christian and not become stagnant
