Control purposes
• To control (compare actual results against the plan) internal information is required. Variance reports are very useful at
arriving at control action
○ Identify sales variances , why has sales fallen; competition?quality issues?
○ Stock inventory levels within org helps to identify ways to increase sales of slow moving items
• External info is useful for benchmarking (with competitors in the same industry; competitive benchmarking).

, • An Intranet is a private network within an organization purpose of an intranet is to share information internally. An extranet is an intranet that can be
partially accessed by authorized outside users enabling businesses to exchange information over the Internet in a secure way. An extranet can limit both
the amount of information available and users who have access to it
Information systems and data analytics
DATA PROCESS INFORMATION
• Managers need information to formulate plans and take decisions if actual results are different from the plan control is needed
• Structured data refers to any data that is contained within a field in a data record or file for example data contained in a
spreadsheet and database
• Unstructured data is data that is not easily contained within a structured data field web pages emails pictures emails blogs are
typically examples of unstructured data. It needs to be analyzed to uncover trends and other information to aid decision making

The big data pyramid by Milan Zeleny Competitive advantage
1987 Improving productivity, reduce idling time
Know why - gives insight and ability to make relevant appropriate business decisions.
Know how - information gotten through data mining can be further processed to
support decision Making.
Know what -move from raw data through a process of data mining; identifying trends
and Patterns in large sets of data. Also identifies relationships such as associations
sequences and Correlation. Through methods such as statistics, machine learning and
database systems. Adding meaning to data structure and context.
Know nothing - unprocessed facts and items such as texts and numbers, vids
Defines a sequence of efforts; model representing structural and functional relationship between
Data, information, knowledge, and wisdom.
Information is defined in terms if data, knowledge in terms of info and widom in terms of knowledge.
Each step up the pyramid answers the questions about and adds value to initial data.
Predicitve analysis - data mining to predict future events. Gives valuable insights based on past data to allow analysts to extrapolate
from the past to assume behaviour and outcomes in the future. Uses statistical models to estimate future outcomes based on past
data.
Data analytics can't be relied upon to predict the future with absolute certainty therefore managers must be skeptical and recognize
limitations of such analysis as predictions can only be based on reasonable probabilities and assumptions.
Big data management
• Storage administration control of a vast quantities of both structured and unstructured data
• Aim is to ensure the data is stored is of high quality and accessible
• Effective data management and analyzing large sets of data from a variety of relatively new sources such as social media sites
• Big data analytics is the process of scrutinizing big data to identify patterns correlations relationships and other insights, this will affect
companies competitive strategy and marketing campaigns and directly affect their future profitability.
• Big data sources may require more advanced software tools than in traditional data mining. Open source technologies such as Hadoop are
constantly evolving,
• Hadoop is an open source programming framework which enables the processing of large datasets from the first phase of the big data
pyramid to the information phase.
