- IT increases personal and organizational productivity.
IT and Digital Transformation
- Digital transformation rewires how an organization operates, building competitive advantage by deploying technology and creating a better customer experience, all while lowering costs.
- Information systems provide support for personal productivity, network interactions, and enterprise business processes.
Creating Successful Digital Transformations
- Four pillars of successful digital transformations are:
- Customer Experience: Providing excellent customer service and meeting their needs
- Operational Efficiency: Streamlining processes and maximizing resource usage
- New Products & Services: Developing innovative offerings to meet new market demands
- Data & Analytics: Utilizing data insights for better decision-making and strategy
- Functional information systems enable the pillars by providing tools for personal productivity, communication, and streamlining business processes.
Crowdsourcing
- Crowdsourcing relies on the wisdom of the crowd to generate ideas and solutions from people outside of the company.
- Examples of crowdsourcing include Wikipedia and Waze.
How Business Processes Drive Value
- A business process is a series of activities designed to accomplish a specific organizational goal, like payroll, hiring, or sales.
- Information systems carry out business processes by capturing data and executing activities.
Robotic Process Automation (RPA)
- RPA uses software bots to automate repetitive, high-volume, rule-based tasks.
- AI can enhance RPA by handling variations and complexity, such as missing data and ambiguity.
Business Process Modeling
- Business process modeling visually represents a business process to understand, communicate, and diagnose existing processes.
- It also aids in managing process change by investigating alternatives and proposing changes.
- Business process models serve as organizational roadmaps.
Business Process Modeling Notation (BPMN)
- BPMN is a standard notation for modeling business processes, ensuring a common understanding across users and tools.
Common Symbols in BPMN
- Start and End Nodes: Indicated by circles, representing the beginning and ending points of a process, with multiple endpoints for different outcomes.
- Activities: Represented by rectangles, these are named tasks that transform inputs into outputs and are performed by specific roles.
- Flows: Depicted by arrows, flows indicate the sequence and movement of data or materials, with labels to describe the content.
- Gateways: Diamond-shaped symbols representing decision points, labeled with a question and exit arrows.
- Pools and Swim Lanes: Pools define the perimeter of a process, subdivided into swim lanes representing actors involved in the process.
Donut Ordering Process Example
- The Donut ordering process uses BPMN to illustrate how roles (customer, cashier, kitchen) interact through activities (order taking, money collection, donut preparation) and flows (communication, materials).
Unit 3: Turning Business Ideas Into Technology Solutions
- Application Software: Programs designed for specific tasks, examples include Word, iMessage, and SAP.
- System Software: Software that makes hardware accessible to applications and manages files, examples include Windows, macOS, and Android.
- Software can be created using programming languages (Python, R, JavaScript) or low-code/no-code platforms (Thunkable, Altair AI Studio).
Implementing IT Solutions
- IT solutions are products delivered through projects.
- Projects are temporary efforts designed to create value, while products deliver value to customers.
- Information technology projects have defined start and end dates, specific objectives, scope, and a budget.
- IT products can include hardware, software, apps, websites, user interfaces, services, or product features.
Project Management
- Project Manager: Operates by breaking initiatives into tasks and timelines.
- Product Manager: Holds a strategic role, responsible for researching, communicating vision, and creating strategic plans.
- Two approaches to project management:
- Waterfall: Well-defined, sequential steps prioritizing efficient, reliable delivery based on initial specifications.
- Agile: Sequential steps of limited scope that repeat (iterations), enabling quick, continuous, and adaptable delivery.
- Hybrid: Combines both waterfall and agile approaches.
Managing Projects: Comparing Waterfall and Agile
- Both approaches have strengths and weaknesses. Success depends on the project specifics and the chosen approach.
- Waterfall is ideal for projects with clearly defined requirements.
- Agile is better for projects where requirements are less clear and need constant adaptation.
- Hybrid is useful for projects with both well-defined and adaptable aspects.
Generating Business Value With Data
- Data: Observations or symbols recorded for future use.
- Information: Data placed in a meaningful context.
- Knowledge: The application of information to achieve goals.
- We are facing a deluge of data, generating 2.5 quintillion bytes daily.
The Business Analytics Process
- Prepare: Collect, gather, clean, and transform data for analysis.
- Perform: Analyze prepared data, including sentiment and trend analysis, and machine learning.
- Use: Make recommendations to aid decision making and generate business value.
Types of Data Analytics
- Descriptive: Summarizing and aggregating raw data to understand what has happened.
- Diagnostic: Identifying relationships within data to understand why something happened.
- Predictive: Utilizing past data to predict future events using AI to identify patterns.
- Prescriptive: Combining descriptive and predictive analytics to recommend future actions, using AI to generate recommendations.
Pitfalls of Analytics Initiatives
- Tyranny of Averages: Averages can be skewed by outliers, leading to inaccurate conclusions.
- Multiple Versions of the Truth: Having conflicting data can lead to confusion and poor decisions.
- Decisions Precede Data: Relying on assumptions instead of data can result in reinforcing incorrect conclusions.
- Misguided Data Driven Incentives: Targeting the wrong data to achieve a desired outcome can be detrimental.
Analytics and Digital Transformation
- Analytics can improve IT systems by identifying bottlenecks and finding new ways to improve processes (IT uplift).
- Analytics helps digitize operations to increase efficiency and productivity.
- Analytics strengthens digital marketing campaigns by optimizing targeting and overall marketing strategy.
- Analytics predicts sales for new ventures, especially using predictive analytics techniques.
Communicating Well With Data
- Effective Data Visualizations:** They speed up data processing, reduce time to insight, and help clarify complex information.
Best Practices for Data Visualization
- State key points: Clearly communicate the main message of the data.
- Conciseness: Avoid unnecessary clutter and focus on essential information.
- Acknowledge source: Provide the origin of the data for transparency.
- Use color wisely: Choose colors carefully to highlight important elements and maintain consistency.
- Text can be powerful: Sometimes, text is the best format to convey information.
- Start axes at 0: Ensure accurate representation by starting axes at zero.
- Avoid chart junk: Minimize unnecessary elements that distract from the data itself.
How AI and Machine Learning Create New Business Opportunities
- Explainable AI: Provides transparency into the reasoning behind AI decisions.
- Dangers of AI:
- Emergent Behaviors: Unexpected and potentially harmful actions.
- Privacy Concerns: Potential misuse of personal data.
- Bias: AI can reflect biases present in the training data and the people who built it.

-
Churn Analysis (Predictive): Identifying customers most likely to switch to competitors.
- Issue: High customer churn.
- Solution: Incentivize customers with high churn likelihood and ignore those with low likelihood.
- Insight: Not all customers have the same value.
-
Cross Selling (Prescriptive): Determining which products customers are likely to purchase.
- Issue: Identifying target customers for cross-selling.
- Insight: Likelihood of purchase depends on previously purchased items.
- Solutions: Offer coupons to customers who have purchased associated items or place related products together.
Types of Machine Learning:
- Supervised Learning: Trains models with data containing correct answers to predict future outcomes.
- Unsupervised Learning: Discovers patterns and relationships within data without labels or specific training data.
Supervised Machine Learning Techniques:
- Decision Trees: Classify data based on pre-defined characteristics to predict outcomes.
- Large Language Models: Predict the next word in a sequence based on vast training data, combining supervised and unsupervised learning.
Unsupervised Machine Learning Techniques:
- Association Mining: Identifies associations between events, like determining which products are frequently purchased together.
Challenges of Machine Learning Models
