Study Notes

Course Overview

Topics include course outline, mathematical models for decision making, and basic spreadsheet skills.
Decision-making process involves analysis, model creation, and interpretation of results.

Managerial Decision Making Process

Starts with defining the problem followed by identifying alternatives and criteria.
Involves modeling, evaluating alternatives, recommending, implementing decisions, and evaluating results.
Iterative approach allows for feedback and adjustment.

Mathematical Models

Models are abstractions representing real processes, incorporating decision variables to enhance system performance.
Used for improving decisions, enhancing understanding of systems, and making explicit trade-offs.

Elements of Models

Decisions: Controllable variables guiding possible actions.
Outcomes: Performance metrics and criteria determining results.
Data: Information impacting conditions and parameters.
Structure: Relationships expressed through equations or inequalities.

Example: Bakery Advertising Decisions

Decision entails selecting advertising spend for November and December.
Outcomes involve maximizing monthly profit.
Data includes selling price (96/dozen),costofingredients(96/dozen), cost of ingredients (96/dozen),costofingredients(50/dozen), and fixed monthly costs ($10,000).

Structure of Model

Net income calculated as revenue minus costs.
Revenue defined as selling price multiplied by demand, while cost includes production expenses and advertising.

Spreadsheet Model Components

Inputs, calculations, outputs, and decisions organized within the spreadsheet.
Use of absolute references in formulas ensures consistency when copied to new columns.

Best Practices for Spreadsheet Design

Sketch layout prior to building the sheet, organizing into modules with isolated input parameters.
Keep formulas simple and use cell references for easier auditing.
Utilize formatting options for clarity and documentation of vital data and formulas.

"What-If" Analysis Tools

Scenarios assess variable changes in advertising expenses and break-even pricing.
Excel offers scenario analysis, data tables, scenario manager, and Goal Seek for output recalibration under different parameter settings.

Advantages and Disadvantages of Spreadsheet Modeling

Common tools include Microsoft Excel, Google Spreadsheets, and others.
Advantages feature widespread usage, availability of add-ins, and cost-effectiveness compared to specialized software.
Limitations include data size constraints, slow processing for large models, and challenges in documentation.

Key Takeaways

Emphasis on structured decision-making backed by mathematical modeling.
Spreadsheet design significantly affects usability and effectiveness for decision analysis.
