Munro's Approach

Munro & Associates has a unique mix of formal technical credentials and hands-on practical skills, coupled with hundreds of combined years of experience that allows us to accurately cost on a wide range of product scopes – from full mechanical teardowns, to theoretical marketing analysis of new concepts in most manufacturing sectors.

When deciding on how best to serve its customers for costing needs, Munro’s dedicated team of professionals, considers a detailed range of variables including materials and material comparisons, process, machinery, tooling, labor, geography, competition, logistics and corporate philosophy from both a business and manufacturing perspective.

R.O.M. Costing in Design

Rough Order of Magnitude costing is often employed when looking at product design or redesign projects.  This type of estimating is also known as Proportioning Historical Costing.  The costs of a future product or process are determined from those of similar existing products and processes to which proportional coefficients are applied.  This method is typically used when there are no perceived important technological differences between the two products or processes or when a rough order magnitude estimate is required.


Munro’s Click2Cost™ service gives our customers a competitive edge in speed by being able to perform detailed costing analyses utilizing our vast costing databases as well as applying known costed parts or processes using your historical data.

We can convert your costing data from Excel or CSV files into the Design Profit® platform where we will use your cost models to diagram your parts manufacturing and assembly processes with the click of a mouse. Alternatively, we can deploy Munro’s material library and costing knowledge to find the material cost of components and subsystems you need or are considering in a redesign.

Bottoms-Up Costing (Detailed)

The most comprehensive and preferred costing method involves understanding all the steps and operations required to deliver a product “Total Accounted Should Cost” estimate.   This process requires definition of the conventional inputs such as labor rates, material costs, machine rates, scrap and also the less easy to attain: tariffs, exit tax, monetary shifts, logistics etc.  This process is called Engineered or “Bottoms-up” estimating.  If, however there is only a need for directional costs, Munro’s Quick Cost Estimating (QCE) is the preferred process.

Detailed Costing Metrics

Over several years, Munro & Associates has developed a detailed, regularly updated, internal database on various cost items as well as a wide range of special costing tools including:

  • International labor and overhead database, maintained to allow the client operation to be modelled anywhere in the world.
  • Tooling database, with most recognized varieties of sheet metal, bulk metal, molds, plastic and composite based tooling requirements.
  • Extensive machinery database, allowing investment vs. process speed to be performed on any process.
  • Configured automotive system comparison tools to allow evaluation of competing configurations.
  • Metal vs. plastics tools for cost comparison at equivalent structure and performance.
  • Multi-composite materials process evaluation vs. metals at equal performance.
  • Plastics and metals compounded materials “should cost” tool based on components percentages.
  • PEM Stack fuel cell detail cost vs. materials and processes of construction.
  • Weight-save vs. material choice and cost tolerance.
  • Risk assessment and management of both material and process

The Munro Costing Advantage

Munro’s intimate and detailed knowledge of the separate disciplines of manufacturing processes, machinery, tooling and product design engineering, structural analysis, performance, durability and testing requirements, coupled with materials engineering, allow us to evaluate alternate materials, processes, and architectures for product equivalence, and limitations.

Munro has a unique corporate resume that allows us to assemble an overwhelming array of in-house credentials, and deep specialty experience in the following disciplines:

  • Material science
  • Theoretical and applied mathematics
  • Encyclopedic collection of industrial processes, machinery, and facilities
  • Product, design and structural engineering
  • Advanced finance and accounting techniques
  • Product planning, risk and benefits programs and experience
  • Product research and development across many industries
  • A deep understanding of assembly and complexity assessments
