The Part Summary tab accumulates key cost information from across the aPriori user interface and summarizes it in a single view. Some displayed values are extracted from other areas of aPriori like the Part Details tab, while others are calculated on the fly by the Part Summary tab to make the information easier to understand. The Part Summary tab displays information that focuses on material, geometry, and high-level production information.
The fields in the Part Summary are not editable or overridable like they are in the Part Details tab. The Part Summary tab is displayed only for parts, not for assemblies.
Examine the different panes to quickly identify areas of cost that exceed targets and expectations, and which could be targeted for cost reduction at the design level.
The following sections show where the Part Summary extracts its values. You can go to these more detailed sections of the UI to drill down for more information when necessary.
Component Information
This mass and part size summary information from the Component properties of the Geometric Cost Drivers panel and the Component Mass section of the Part Details tab:
Production Information
This summary of production info comes from values found on the Cost Guide (and replicated in the Cost Object window). Lifetime Volume is calculated by the Part Summary tab from the Annual Volume and Production Life values.
Material Information
The Material Information panel summarizes information that can be found in the Material Info section of the Part Details tab and the Material Selection window (available from the Manufacturing Process panel).
A low Utilization (%) value can alert you to possible actionable issues. For example, a cast part is typically a "net" shape and should have a high utilization part. A high Unit Cost might indicate a design element that requires a premium material. Values that depart from expectations can indicate something to explore.
Note: If you are working with a process group that uses stock material, such as Sheet Metal, Bar & Tube, the "Stock" field of the Material Information panel will be populated with relevant info from the Material Stock section of the Material Selection window.
Cost by Category (%)
The Cost by Category (%) panel shows you at a high level where most of your costs are coming from. The Part Summary tab extracts various key values and calculates the percentage they represent of the Fully Burdened Cost for the part. Material, Labor, Overhead, Setup, and Investment all come from single values that can be viewed in the Part Details tab as shown below. Other is calculated by summing together multiple values: Logistics, Other Direct, Margin, Period Indirect Overhead, and SG&A. You can easily view the source for these percentages by holding your mouse over an entry to display a tool tip.
Note: Adding together the Labor, Overhead, and Setup percentages will tell you how much of the total cost is being spent on processes, the details of which can be viewed in the next panel (Cost by Process).
Cost by Processes (%)
The Cost by Process (%) panel panel shows which processes are contributing the most to the cost of manufacturing the part. A process that seems excessively costly may be a candidate for further investigation and possibly a design improvement.
-
The percentage contribution of each process is calculated by comparing the sum of various process-related costs for that specific process, to the sum of these costs across all processes used in the routing.
-
This sum is used rather than basing the percentage on Piece Cost or Fully Burdened Cost (FBC), because for some processes the Material cost is included in Piece Cost and FBC and would result in a skewed comparison. Therefore, the Cost by Process calculations assume no contributions from Material, Material Overhead, SG&A, or Margin.
The calculation is:
Process:
(Labor Cost + Direct Overhead + Logistics + Amortized Batch Setup Costs +
(Other Direct Costs - Material Overhead) + Indirect Overhead Costs +
Fixed Costs) for the process
Divided by
Sum of (Labor Cost + Direct Overhead + Logistics + Amortized Batch Setup Costs +
(Other Direct Costs - Material Overhead) + Indirect Overhead Costs +
Fixed Costs) for processes
Note: Clicking the Process column heading will sort the table alphabetically and clicking the Percent Cost heading will sort the table numerically.
Component Costs and Targets
The Component Costs and Targets panel provides a quick indication of how the part stands regarding cost and mass goals (allow for some rounding differences). Targets are typically set in the Cost Guide.
