McGraw Hill Operations Management Simulation module 6 focuses on guiding teams toward decisions that maximize net worth. By blending quantitative analysis with strategic trade offs, this module challenges you to balance capacity, inventory, and financing choices for long term value.
Below is a structured overview of the core levers and outcomes you should track in this module. Use this table as a quick reference when making scenario decisions and reviewing your performance.
| Decision Lever | Impact on Net Worth | Primary Risk | Recommended Action |
|---|---|---|---|
| Production Capacity | Higher utilization increases contribution margin | Over capacity leads to excess inventory | Match capacity to realistic demand forecasts |
| Inventory Levels | Balanced stock reduces stockouts and holding cost | Excess raw work in process ties up cash | Adopt lean pull principles and limit WIP |
| Financing Mix | Lower cost debt improves net worth when managed safely | High leverage raises default and stress risk | Use debt for profitable expansions only |
| Product Mix | High margin products boost return on assets | Narrow mix increases demand and cycle time variability | Diversify while prioritizing highest contribution per constraint |
Analyze Cost Structure And Capacity Decisions
Examining direct, indirect, and fixed costs reveals where every dollar of capacity is spent. In module 6, you must compare the cost of adding capacity against the expected contribution from additional output. Focus on the constraint step, because it governs overall throughput and net worth.
Use data from the simulation dashboards to compare scenarios such as adding shifts, cross training, or outsourcing. Each option should be evaluated on incremental cost, lead time impact, and effect on inventory carrying cost. Choose options that improve throughput while keeping operating expenses in check.
Optimize Inventory And Working Capital
Inventory decisions directly affect cash flow and net worth. Reduce cycle stock by tightening lot sizes and improving schedule adherence. Safety stock should be set at levels that balance service targets against the cost of trapped capital.
Apply pull signals and takt time pacing to prevent overproduction. Cutting work in process frees up space, reduces handling costs, and shortens lead times. Monitor inventory velocity and adjust policies quickly when demand patterns shift in the simulation.
Refine Demand Forecasting And Product Mix
Accurate demand forecasts allow you to align production plans with market needs. In module 6, evaluate forecast error metrics and adjust plans using rolling updates. A stable demand pattern reduces schedule chaos and improves resource utilization.
Prioritize products with the highest contribution margin per constraint hour. Rebalance the product mix toward high margin items while managing variability. This approach increases throughput per unit of capacity and supports stronger net worth outcomes.
Key Takeaways For Maximizing Net Worth

- Reduce work in process and cycle stock to free cash
- Prioritize high margin products while managing variability
- Use debt conservatively and tie it to clear value creation
- Monitor KPIs such as inventory turns and contribution per constraint
- Update forecasts frequently and adjust plans in the simulation
FAQ
Reader questions
How do I decide whether to invest in additional machinery in module 6?
Compare the net present value of the investment against the current constraint utilization. Invest only when the added throughput exceeds the capital and operating costs, and when demand forecasts support the extra capacity.
What is the best way to reduce inventory without causing stockouts?
Tighten lot sizes, move toward pull based production, and right size safety stock using service level targets. Monitor inventory turns and adjust reorder points as demand patterns change in the simulation.
How does product mix affect my net worth score in the simulation?
Shifting mix toward higher margin products at the constraint increases throughput per hour and improves net worth. Avoid over specializing if it raises variability or exposes you to demand shocks.
Is it better to use more debt to finance growth in module 6?
Use debt strategically for profitable capacity or mix changes, but keep leverage at a level your operation can withstand. High interest cost and rigid repayment schedules can damage net worth if demand underperforms.
