enables sensor embedded products to share reliable real time data via radio signals
Unstructured Data
Do not have a predictable format
Data Science
involves managing and analyzing massive sets of data for purposes such as marketing, trends, etc.
Business Processes
Series of steps by which organizations coordinate and organize tasks to get work done.
Formal Processes
documented and have well-established steps. Taking a CC pmt
Standard Operating Procedures
Who performs, What materials, where
Business Process Re-engineering
Methods and efforts to eliminate wasted steps within a process
Agility
being able to respond quickly
Responsiveness
that IT capacity can be easily scaled up or down as needed, which requires cloud computing.
Flexibility
having the ability to quickly integrate new business functions or easily reconfigure software or apps
Rules of SWOT
Be realistic about strengths and weaknesses
Also about size of Ops + Threats
Specific and keep analysis simple
Evaluate strengths + weaknesses
Expect conflicting views, SWOT is subjective
Five Industry Forces
Threat of entry new competitors
Bargaining power of suppliers
Bargaining power of customers or buyers
Threat of substituting products or services
Competitive rivalry among existing firms in the industry
5 Primary Activities
Inbound logistics- acquiring and receiving of raw materials and other inputs
Operations - manufacturing and testing
Outbound Logistics - packaging, storage, delivery, distribution
Marketing and Sales - customers
Services - customer services
Support Activities
Primary Activities rely on them. Infrastructure, accounting, finance HR R&D Procurement or purchasing
Data Governance
is the control of enterprise data through formal policies and procedures
Enterprise Architecture
guides the evolution and expansion of information systems, digital technology, and business processes.
Customer Centeric
best suited for the cutomer
Touchpoint
any influencing action initiated through communication, human contact or physical or sensory interaction
Dirty Data
data of such poor quality that they cannot be trusted or relied upon for decisions
Master Data Management
methods synchronize all business critical data from disparate systems into a master file, which provides a trusted data source
Information management
use of IT tools and methods to collect, process, consolidate, store, and secure data from sources that are often fragmented and inconsistent.
Data Silo
data stores in which their data are not accessible by other ISs that need it or outside of that department
Data Silos Exist When:
there is no overall IT architecture to guide IS investments, data coordination, and communication
Advantages of information management are:
Improves decision quality
Improves the accuracy and reliability of management predictions
Reduces the risk of non compliance
Reduces the time and cost
Problems that Enterprise Architecture is designed to Address
IT systems Complexity
Poor business alignment
Benefits of having the right Enterprise Architecture in place
Cuts IT cost + increases productivity
Determines an organizations competitiveness
align capabilities with strategy
Components of Enterprise Architecture
Business Architecture - The process the business uses to meet its goals
Application architecture - how specific applications are designed and how they interact with each other
Data Architecture - How an enterprise’s data stores are organized and accessed
Technical architecture - the hardware and software infrastructure that supports applications and their instructions.
Database
is a repository or data store that is organized for efficient access, search, retrieval, and update
Information
data that have been processed, organized or put into context so it has meaning
Knowledge
Consists of data and/or information that has been processed, organized, and put in context to be meaningful, and to convey undedstanding
Transaction Processing Systems
designed to process specific types of data input from ongoing transactions
Types of Transactions
Internal - originate within the organization. payroll, purchases
External - originate from outside the organization. customers, suppliers, etc
Batch Processing
TPS in batch mode collects all transactions for a day, shift, or other rime period, then processes the data and updates the data stores
Online Transaction Processing
TPS processes each transaction as it occurs, which is what is meant by the term real time processing. Webiste must be linked via a network to the TPS
Management Information Systems
Their objective is to provide reports to managers for tracking operations, monitoring, and control
Decision support systems (DSS)
INTERACTIVE APPLICATIONS THAT SUPPORT DECISION MAKING.
Unstructured Decision
depend on human intelligence, knowledge, and/or experiences
What if Analysis
refers to changing assumptions or data in the model to observe the impacts of those changes on the outcome.
Data Center
a large number of network servers used for the storage, processing, management, distribution and archiving of data, systems, web traffic, services and enterprise applications
Service Level Agreements
A negotiated agreement between a company and service provider that can be a legally binding contract or an informal contract.
Software as a service(SaaS)
any software that is provided on demand
Google Apps
Salesforce.com

Hardware Layer
What is Virtualization
is a Technique that creates a virtual layer and multiple virtual machines to run on a single physical machine.
PaaS -
set of tools and services that make coding and deploying these apps faster and more efficeint
Iaas- Information as a service
consists of hardware and software that power computing resources servers, storage, os, and networks
Data as a Service (DaaS)
enables data to be shared among clouds, systems, apps, and so on regardless of the data source or where they are stored.
Centralized Databases
Store data at a single location that is accessible from anywhere.
Volatile Data
can change frequently
