o “What are the cost-effective business applications of social media? ▪ Companies use social media data to process capabilities on the cloud ▪ Business User’s of these technologies need to be able to analyze the cost-effectiveness of these features to see if they are worth investment. ▪ Users must be able to asses, evaluate and apply information in business decision-making. Moore’s Law → Any routine skill will be outsourced o “How can I attain job security?” ▪ Attain job security by having a marketable skill and the confidence to use it ▪ Routine skills are not enough for success, because of Moore’s law they will be outsourced → Which is why you need Non-Routine Cognitive Skills Component Abstract Reasoning Systems Thinking Collaboration

Ability to Experiment

Jobs:

4 Components of Non-Routine Cognitive Skills Definition The ability to make and manipulate models. The ability to model the components of the system to connect the input and outputs among those components The activity of two or more people working together to achieve a common goal. Making reasoned analysis of an opportunity, envisioning potential solutions, evaluating those possibilities and developing the most promising ones, consistent with the resources you have.

Example Construct a model or representation Being able to connect a can of beans to US Immigration policy. Develop ideas and plans with others. Provide and receive critical feedback Create and test promising new alternatives, consistent with available resources.

ISA235 Notes

Exam 1 ● Jobs with studies in information systems have higher after graduation placement rates. ● Tradable Jobs: One that was not dependent on a particular location, meaning it can be outsourced. o Figure 1-3 ▪ Many jobs are being outsourced ▪ Computer Systems jobs are sky rocketing, and is expecting to continue ● The myth that all computer science jobs are overseas is false.

Historically -Education -Industry

Wage Determination Now -Nature of work -As the price of technology decreases, the value of jobs that benefit from it increase dramatically.

Bottom Line: This course is the most important course in business because… 1. It will give you the background you need to assess, evaluate, and apply emerging information systems in technology into business 2. It can give you the ultimate job security- marketable skills- by helping you learn abstraction, systems thinking collaboration and experimentation 3. Many MIS jobs are available and the market for them is going to grow.

ISA235 Notes

Exam 1 Information systems improve process quality: which is measured by process effectiveness and process efficiency. ● Effective Business Process: One that enables the organization to accomplish its strategy. ● Process Efficiency: The ratio of benefits to costs. Using Information Systems to Store Vendor Data Actors Hardware Follows instructions from software

Instructions Software

Bridge Data

Instructions for hardware

Instructions Procedures Instructions for people

Computer Side

Actors People Follows instructions from procedures

Human Side

Automation: Moves from human side to computer side, activities formally done by people are moved to computers who follow directions of the software. Data: Plural Datum: Singular Store Vendor Product and Performance Data in a Database ● Business users must be able to develop processes in order to create a system worth the costs

Q4: What is information? Data: Recorded facts or figures Information: ● Knowledge derived from data= Information ● Data presented in a meaningful context

Exam 1 ● ● ● ●

Processed data = information Processed data by summing, ordering, averaging, grouping, comparing or other operations Human conceives data from information In the mind of a human, which is why humans are most important to information systems.

Q5: What data characteristics are necessary for quality information? ● Quality of information you create depends in part on your thinking skills 1. Accurate a. Must be correct an complete b. Crucial for management c. Cross-Check information to ensure accuracy i. When you begin a new information system, be skeptical 2. Timely a. Available in time for its intended use 3. Relevant a. To context- summarized to a level meaningful to the viewer b. To subject- focused on the data/information needed 4. Just barely sufficient a. You will have to ignore some data given the vast amount of data available to you 5. Worth the cost a. Relationship between cost and value, must be worth the cost b. Hurdle Rate—percentage of return on investment (factoring in risk) i. Developing the IS ii. Operating and maintaining the IS iii. Salary for reading and processing the data the system produces

ISA235 Notes

Exam 1 Two Dimensions of Process Quality: 1. Efficiency: It does not waste resources a. Use of resources 2. Effectiveness: It accomplishes what it is supposed to do. a. Accomplish strategy Change in Technology ● The second reason for managing processes ● Causes the entire process to be re-evaluated to make sure that it can keep up Changes in Business Fundamentals ● The third reason for changing managing processes is a change in business fundamentals A change in any of the following might result in the need to alter business processes: ● Market ● Product lines ● Supply Chain ● Company Policy ● Company organizations ● Internationalizations ● Business Environment

Q2: What are the stages of business process management? (BMP) 3 Options for Changes in Business Processes 1. Plan to develop or modify business processes 2. Wait and let the need to change happen a. Usually results in crisis or emergency

Assessing the business model a. Evaluating is done by the same users who create the model 4. Create Process Components i. If the solution involves an information system then it is created or adapted at this point ii. New changed business processes, along with any necessary IS, are implemented.
