Manufacturing Readiness Level

Manufacturing Readiness Level

Manufacturing Readiness Level ("MRL") is a measure used by some United States government agencies and many of the world's major companies (and agencies) to assess the maturity of manufacturing readiness serving the same purpose as Technology Readiness Levels serve for technology readiness. They can be used in general industry assessments,[1] or for more specific application in assessing capabilities of possible suppliers. The Government Accountability Office has described it as best practice for improving acquisition outcomes,[2] and the United States Department of Defense ("DOD") now requires consideration of manufacturing readiness and related processes of potential contractors and subcontractors as part of the source selection process in major acquisition programs.[3][4]

MRLs are quantitative measures used to assess the maturity of a given technology, component or system from a manufacturing prospective. They are used to provide decision makers at all levels with a common understanding of the relative maturity and attendant risks associated with manufacturing technologies, products, and processes being considered. Manufacturing risk identification and management must begin at the earliest stages of technology development, and continue vigorously throughout each stage of a program’s life-cycles.

Manufacturing Readiness Level (MRL) definitions were developed by a joint DoD/industry working group under the sponsorship of the Joint Defense Manufacturing Technology Panel (JDMTP). The intent was to create a measurement scale that would serve the same purpose for manufacturing readiness as Technology Readiness Levels ("TRLs") serve for technology readiness – to provide a common metric and vocabulary for assessing and discussing manufacturing maturity, risk and readiness. MRLs were designed with a numbering system to be roughly congruent with comparable levels of TRLs for synergy and ease of understanding and use.


Why Manufacturing Readiness?

  • Manufacturing risk identification and management must begin at the earliest stages of technology development, and continue vigorously throughout each stage of a program’s life-cycle.
  • Matters of manufacturing readiness and producibility are as important to the successful development of a system as those of readiness and capabilities of the technologies intended for the system.

Assessing MRLs is performed to:

  • define the current level of manufacturing maturity
  • identify maturity shortfalls and associated costs and risks
  • provide the basis for manufacturing maturation and risk management

Products made by immature manufacturing processes generally:

  • Cost more
  • Are prone to quality problems
  • May not all perform the same
  • Have a hard time delivering on schedule

Assessing technology readiness levels does leave some major transition questions unanswered:

  • Is the technology producible?
  • What will this cost in production?
  • Can these be made in a production environment?
  • Are key materials and components available?

Manufacturing Readiness Assessments (MRAs) address these unanswered questions in order to reduce manufacturing risk. However, it still does not address the question of whether the product is reliable or maintainable.


The following has been adopted by the DOD as appropriate in assessing manufacturing readiness levels:[5]

Phase (as specified by DoDI 5000.02[6] Leading to MRL Definition Desc
Prior to Materiel Solution Analysis Materiel Development Decision review 1 Basic Manufacturing Implications Identified This is the lowest level of manufacturing readiness. Basic research expands scientific principles that may have manufacturing implications. The focus is on a high level assessment of manufacturing opportunities. The research is unfettered.
2 Manufacturing Concepts Identified Invention begins. Manufacturing science and/or concept described in application context. Identification of material and process approaches are limited to paper studies and analysis. Initial manufacturing feasibility and issues are emerging.
3 Manufacturing Proof of Concept Developed Conduct analytical or laboratory experiments to validate paper studies. Experimental hardware or processes have been created, but are not yet integrated or representative. Materials and/or processes have been characterized for manufacturability and availability but further evaluation and demonstration is required.
Materiel Solution Analysis Milestone A decision 4 Capability to produce the technology in a laboratory environment. Required investments, such as manufacturing technology development identified. Processes to ensure manufacturability, producibility and quality are in place and are sufficient to produce technology demonstrators. Manufacturing risks identified for prototype build. Manufacturing cost drivers identified. Producibility assessments of design concepts have been completed. Key design performance parameters identified. Special needs identified for tooling, facilities, material handling and skills.
Technology Development Milestone B decision 5 Capability to produce prototype components in a production relevant environment. Manufacturing strategy refined and integrated with Risk Management Plan. Identification of enabling/critical technologies and components is complete. Prototype materials, tooling and test equipment, as well as personnel skills, have been demonstrated on components in a production relevant environment, but many manufacturing processes and procedures are still in development. Manufacturing technology development efforts initiated or ongoing. Producibility assessments of key technologies and components ongoing. Cost model based upon detailed end-to-end value stream map.
6 Capability to produce a prototype system or subsystem in a production relevant environment. Initial manufacturing approach developed. Majority of manufacturing processes have been defined and characterized, but there are still significant engineering/design changes. Preliminary design of critical components completed. Producibility assessments of key technologies complete. Prototype materials, tooling and test equipment, as well as personnel skills have been demonstrated on subsystems/ systems in a production relevant environment. Detailed cost analysis include design trades. Cost targets allocated. Producibility considerations shape system development plans. Long lead and key supply chain elements identified. Industrial Capabilities Assessment for Milestone B completed.
Engineering and Manufacturing Development post-CDR (Critical design review) Assessment 7 Capability to produce systems, subsystems or components in a production representative environment. Detailed design is underway. Material specifications are approved. Materials available to meet planned pilot line build schedule. Manufacturing processes and procedures demonstrated in a production representative environment. Detailed producibility trade studies and risk assessments underway. Cost models updated with detailed designs, rolled up to system level and tracked against targets. Unit cost reduction efforts underway. Supply chain and supplier Quality Assurance assessed. Long lead procurement plans in place. Production tooling and test equipment design and development initiated.
Milestone C decision 8 Pilot line capability demonstrated. Ready to begin low rate production. Detailed system design essentially complete and sufficiently stable to enter low rate production. All materials are available to meet planned low rate production schedule. Manufacturing and quality processes and procedures proven in a pilot line environment, under control and ready for low rate production. Known producibility risks pose no significant risk for low rate production. Engineering cost model driven by detailed design and validated. Supply chain established and stable. Industrial Capabilities Assessment for Milestone C completed.
Production and Deployment Full Rate Production decision 9 Low Rate Production demonstrated. Capability in place to begin Full Rate Production. Major system design features are stable and proven in test and evaluation. Materials are available to meet planned rate production schedules. Manufacturing processes and procedures are established and controlled to three-sigma or some other appropriate quality level to meet design key characteristic tolerances in a low rate production environment. Production risk monitoring ongoing. LRIP cost goals met, learning curve validated. Actual cost model developed for Full Rate Production environment, with impact of Continuous improvement.
Operations and Support N/A 10 Full Rate Production demonstrated and lean production practices in place. This is the highest level of production readiness. Engineering/design changes are few and generally limited to quality and cost improvements. System, components or items are in rate production and meet all engineering, performance, quality and reliability requirements. All materials, manufacturing processes and procedures, inspection and test equipment are in production and controlled to six-sigma or some other appropriate quality level. Full Rate Production unit cost meets goal, and funding is sufficient for production at required rates. Lean practices well established and continuous process improvements ongoing.
