CHAPTER 2: BUSINESS PROCESSES, INFORMATION, AND DECISION MAKING
WHAT IS A BUSINESS PROCESS?
Business process: a network of activities, resources, facilities, and information that interact to achieve some business objective
oEx: inventory-management processes, manufacturing processes, sales processes, customer-support processes
WHAT ARE THE COMPONENTS OF A BUSINESS PROCESS?
Activities: transform resources and information of one type into resources and information of another type
oCan consist or be made up of strictly manual activities, automated, or combination
oExample: inventory-management process
Payment (activity) transforms
Quantity Received (information) and Shipping Invoice (information)
Payment to Supplier (resource)
Resources: items of value
Facilities: structures used within the business process
oInventories and databases
Information: used by activities to determine how to transform the inputs they receive into the outputs they produce
Business process modeling notation (BPMN): provides a standard set of terms and graphical notations to document a process
WHAT IS INFORMATION?
Knowledge derived from data (facts or figures)
Data presented in a meaningful context
Processed data (processed by summing, ordering, averaging, grouping, comparing, performing other similar operations)
Characteristics of Good Information
Accurate  based on correct and complete data and has been processed correctly as expected
Timely  produced in time for its intended use
Relevant  both to the context and to the subject
Sufficient  for the purpose for which it is generated, but just barely so
Worth its cost  appropriate relationship between the cost of it and its value
WHAT IS THE ROLE OF INFORMATION IN BUSINESS PROCESSES?
Any time a good is moved or a service is provided, data and information are always created
Any time there is a physical flow, there is the potential to capture a flow of information
Business process generates information by bringing together important items of data in a context
Lets us know when we need to make payments for goods/services received
Keep track of what’s been delivered and what hasn’t  keeps inventory up to date
Business Process Management (BPM)
Business process management (BPM): the process of generating information that will be useful for management and strategy
decisions
Promotes the development of effective and efficient processes through continuous improvement and innovation
Methods of BPM:
oTotal Quality Management (TQM), Six Sigma, Lean Production
