Questions and Answers

Contrast the fundamental differences in material transformation between discrete and process manufacturing by providing an example where the distinction might blur, such as in the manufacturing of certain composite materials.

Discrete manufacturing deals with distinct, countable items assembled from components (e.g., cars), allowing disassembly. Process manufacturing involves transforming raw materials through formulas or recipes into inseparable products (e.g., chemicals). The distinction blurs with composite materials like carbon fiber car parts, where the process involves chemical reactions (process) but results in a discrete component (part).

Explain how the 'engineer-to-produce' approach differs fundamentally from 'design-to-produce' in the context of product customization and complexity, particularly concerning the level of pre-defined specifications.

'Design-to-produce' involves creating customizable products from a set of pre-designed options, offering flexibility within established boundaries. 'Engineer-to-produce' handles highly specialized products with no pre-defined design, requiring engineers to create bespoke solutions from initial specifications, often for complex, unique projects.

Analyze the implications of choosing a 'make-to-stock' strategy for a company experiencing highly volatile demand, considering both potential benefits and significant risks associated with inventory management.

Make-to-stock in volatile demand can ensure immediate order fulfillment during peaks, capitalizing on potential sales. However, it risks high inventory holding costs and potential obsolescence during demand troughs, leading to significant financial losses if demand forecasts are inaccurate.

Describe how a Bill of Materials (BOM) not only lists components but also serves as a critical document for production planning and cost estimation, especially when dealing with multi-level BOMs.

A BOM details all components for a finished product, crucial for production planning by specifying material needs and quantities. For cost estimation, especially with multi-level BOMs, it enables calculating the total cost by aggregating costs of raw materials, sub-assemblies, and purchased parts at each level.
