Ventana Production Models focus on the technocal and human factors affecting a manufacturing or service delivery process. they are used by managers to find the root cause of throughput and productivity limits, understand and accelerate production learning curves, and determine in advance the likely payoff of process improvement initiatives.
for an aircraft manufacturing, ventana modeled the production process to learn why manufacturing costs continued to climb despite significant investment to reduce them. sorting out the massive volume of data and the complexity of the business, ventana showed that the company's in- house econometric model for understanding the sources of operating problems was invalid, and that the company was vastly overestimating the impact of parts shortages on thier assembly poerations while underestimating the effects of using inexperienced assembly labor.
For a business unit of a large chemicals manufacturer, ventana combined a technical model of the product and the quality testing process with a model of the financial implications. by identifying a previously unrecognized opportunity inherent in tests, significantly reducing the unit's controllable expenses.
