This measure calculates warranty costs (repair and replacement) as a percentage of sales. Warranty costs include materials, labor, and problem diagnosis for products returned for repair or refurbishment. This measure is part of a set of Process Efficiency measures that help companies optimize the performance of their "produce/manufacture/deliver product" process by minimizing waste and refining resource consumption.

Process efficiency

Process efficiency represents how well a process converts its inputs into outputs. A process that converts 100% of the inputs into outputs without waste is more efficient than one that converts a similar amount of inputs into fewer outputs.

Median

The metric value which represents the 50th percentile of a peer group. This could also be communicated as the metric value where half of the peer group sample shows lower performance than the expressed metric value or half of the peer group sample shows higher performance than the expressed metric value.

    • 4.3.1.7 - Release production orders and create lots (10309) - Initiating the delivery of production orders, and creating lots. Communicate the order that specifies which material to produce, where to produce it, which operations to require, and on which date production takes place. Define how to settle the order costs. Create production lots, which is a particular production unit of an assembly that is planned and manufactured.
  • 4.3.2 - Produce/Assemble product (10304) - Manufacturing the product. Convert the raw materials to develop consumer-ready products. Manage the raw materials to implement the detailed production schedule. Reproduce defectives to establish and remediate cause. Ensure production optimization and benchmark performance.
    • 4.3.2.1 - Manage raw material inventory (10310) - Administering the inventory of raw materials. Manage the total cost of all component parts in stock but not yet used. Manage the cost of the direct materials (i.e., materials incorporated into the final product) and indirect materials (i.e., materials not incorporated into the final product but consumed during the production process).
    • 4.3.2.2 - Execute detailed line schedule (10311) - Creating and implementing the detailed line production schedule on the ground level.
    • 4.3.2.3 - Report maintenance issues (10319) - Recording and reporting any deviations or issues in the maintenance schedule, in the performance to the production management team, and for unplanned maintenance.
    • 4.3.2.4 - Rerun defective items (10313) - Reproducing the items produced defectively. Assess the produced items by conducting quality and standardization tests in order to diagnose any discrepancies. Reproduce defective items.
    • 4.3.2.5 - Monitor and optimize production process (19566) - Integrating different resources in the production process: material, personnel, equipment, robotics, etc. Includes automating and controlling the plant, performing advanced process control and real-time optimization. This activity also includes managing plant alarms and alerts.
      • 4.3.2.5.1 - Automate and control plant (19567) - Creating and applying technology to monitor and control the production and delivery of products and services. Automation involves a broad range of technologies.
      • 4.3.2.5.2 - Perform advanced process control (19568) - Including a broad range of techniques and technologies implemented within industrial process control systems that are routinely reviewed, audited, and improved, advanced process controls typically address particular performance or economic improvement opportunities. An advanced set of process control measures can be used to reduce variation and identify primary improvement options. Results of analysis are fed back into process design for incorporation into production.
      • 4.3.2.5.3 - Perform real-time optimization (19569) - Helping organizations increase performance and efficiency, real-time optimization is a category of closed-loop process control that aims at optimizing process performance in real time for systems.

    • 4.3.3.6 - Perform root cause analysis (12046) - Using a technique that helps people answer the question of why a problem occurred in the first place. It seeks to identify the origin of a problem using a specific set of steps, with associated tools, to find the primary cause of the problem to determine what happened, why, and how to reduce the likelihood that it will happen again.
