MGMT90141 Business Analysis and Decision Making develops linear and integer programming, decision analysis, probability and regression for managerial choices. It is taught within The University of Melbourne Faculty of Business and Economics. It is a graduate coursework management subject. It carries 12.5 points.
- Model before Solver Define variables, objective, constraints and units before opening Solver; a spreadsheet cannot repair a mistaken decision model.
- Information has a ceiling Perfect-information value is an upper bound on what any sample or research programme should be worth.
- Regression is conditional A coefficient describes an estimated conditional relationship under the model; it does not by itself prove causation.
- Timing conflict visible Official sources disagree on presentation duration, so use the current LMS instruction rather than memorising a number from this guide.

What MGMT90141 covers
Build the course in three arcs: Decision Models, Variables and Objectives establishes the frame, Descriptive Statistics and Probability Basics deepens it, and Presentation and Examination Integration tests the complete method.
Decision Models, Variables and Objectives
decision variable · objective function · constraint · translate an organisational problem into a dimensional mathematical model before using software02Feasible Regions, Binding Resources and Sensitivity
feasible region · binding constraint · shadow price · interpret an optimal solution through resource scarcity and the range over which marginal information remains valid03Integer and Logical Business Decisions
binary variable · integer programming · logical constraint · model indivisible, setup and either-or decisions without accepting infeasible fractions04Decision Trees and Expected Outcomes
decision tree · expected monetary value · risk profile · sequence choices and uncertain events before comparing probability-weighted consequences05Perfect Information and the Value of Learning
perfect information · sample information · posterior probability · set an upper bound on research value and update decisions when evidence is imperfect06Descriptive Statistics and Probability Basics
descriptive statistic · probability model · random variable · summarise observed business data and state the probability assumptions used for a decision07Probability Distributions for Business Risk
probability distribution · expected value · variance · select and interpret a distribution that matches the outcome support and business process08Simple Regression and Residual Evidence
linear regression · residual · coefficient · estimate and diagnose a one-predictor relationship before using it for explanation or prediction09Multiple Regression, Confounding and Collinearity
multiple regression · confounding · multicollinearity · interpret a coefficient conditionally while diagnosing omitted structure and unstable predictors10Sensitivity, Validation and Managerial Recommendation
sensitivity analysis · model validation · managerial recommendation · stress-test a result and communicate a decision that remains explicit about assumptions and implementation11Presentation and Examination Integration
managerial recommendation · decision variable · residual · explain a model to non-experts and retrieve the quantitative workflow under time pressureIt is positioned as a quantitative business-analysis and decision-science subject.
Students select an organisational optimisation problem, review relevant modelling literature, build and solve a model, communicate it to non-experts and sit a 50% examination.
Assessment in MGMT90141 is distributed as follows: 15% 2,000-word group assignment, 30% 4,000-word group assignment, 5% group presentation and 50% two-hour end-of-semester examination
The operational assessment conditions matter here.
The examination is two hours during the examination period.
The official sources do not publish question count or format, and the current Subject Guide prohibits AI in every assessment.
What makes MGMT90141 demanding is concrete: Translating a messy organisational decision into variables, objective, constraints and data, then interpreting solver or statistical output without treating a mathematically optimal answer as automatically feasible or causal.
The rendered Semester 2 Handbook table contains no hurdle marker or published component pass threshold;
live LMS instructions still control operational requirements.
For enrolment planning, Use the current Handbook eligibility page for enrolment requirements; the build does not infer them from the subject code.

Coverage note: the Handbook says a 10-12 minute presentation while the current Subject Guide specifies 10 minutes and a separate instruction sheet says 8 minutes;
the LMS controls delivery timing.
Formulate a product-mix decision before solving it
- 1Define non-negative decision variables A and B as units produced.
- 1Write the objective: maximise 30A plus 24B.
- 1Write the labour constraint: 2A plus B is at most 8.
- 1Write the demand constraint: B is at most 5.
- 1State whether divisibility is reasonable before selecting linear or integer variables.
Key terms
- Decision tree
- A branching representation of decisions, uncertain events, probabilities and consequences evaluated in sequence.
- Multiple regression
- A regression model relating a response to two or more predictors while estimating each coefficient conditional on the others.
- Decision variable
- A controllable quantity whose value is chosen by an optimisation model to represent a managerial action.
- Objective function
- A mathematical expression of the performance measure that a model seeks to maximise or minimise.
- Constraint
- A mathematical restriction representing a resource limit, requirement or relationship among decision variables.
- Feasible region
- The set of all decision-variable values satisfying every constraint in an optimisation model.
- Shadow price
- The marginal change in the optimal objective value associated with a one-unit increase in a binding constraint's right-hand side within its valid range.
- Integer programming
- Optimisation in which specified decision variables must take integer or binary values rather than arbitrary fractions.
- Expected value
- A probability-weighted average of possible outcomes used to compare alternatives under stated beliefs and payoffs.
- Bayes theorem
- A rule for updating a prior probability with evidence represented by a likelihood to obtain a posterior probability.
