Manufacturing Readiness Review (MRR)

V 1.0

Definition  The Manufacturing Readiness Review (MRR) is held as such after the Pilot Build step. In other instances, Manufacturing Readiness is addressed as part of the Technical Reviews (PDR, CDR, Alpha and Beta Readiness Review, FDR) which are held during the development of a new product. 

The main objective of the MRR is to assess whether the manufacturing process is ready to proceed to volume production 

Questions 

Assessment of current status 
  • Has DFM been performed and taken into consideration at product design level? 
  • Is the Manufacturing Process able to support the product performance objectives? 
    • Production process flow 
    • Technological challenges and current status (TVs, BGA, ASIC, PCB) 
    • Test Vehicles challenges and results (emphasis on predicted performance) 
    • Cards main features (Statistics on the Assembly, types of components, PCB, special process requirements) 
    • Associated time and yields for the first 3 months in production 
    • Reliability plan 
    • Quality Plan (Tools, Reports and Targets by means of ARR, DOA and Yields 
  • Is the Contract Manufacturer capable of supporting the Manufacturing Process? 
    • Status of last build 
    • Sub-contractor responsiveness and support 
    • Main issues and issue resolution 
    • Actual results vs predictions 
    • Assessment of Fast Turn-Around Prototype Process 
    • Risks 
Are the cost elements in line with the predictions? 
    • Forecast of NREs (Test Equipment, Assembly tools, PCB tools, Trails) 
    • BOM, Material Margin, Assembly, Test and Standard Cost 
    • Cost of manual additions/deletions (ECOs)? 

Testing Readiness 

  • Has DFT been performed and taken into consideration at design level? 
  • Are the testing scheme and process of introduction for the next builds defined? 
  • Are the testing scheme and process for the full production (including debug tools) defined? 
  • Have the testing resource been allocated? 
  • What is the status of ICT fixtures, Burn In and System test fixtures design 
  • What Test Equipment do we need in order to complete the development of our tests? 

Supply-Chain 

  • Have the long Lead Items List (sorted by lead time in weeks and by cost range) been identified? 
  • What is the Strategic Components status (ASICs, PCB, single source)? 
  • Have the cost reduction opportunities been identified and leveraged? 

Readiness for Volume Production 

  • Is the Product Forecast ready (Quantities per Quarter)? 
  • Is the Product Release plan defined and approved (Time Table of the coming main mile stones, Product Tree and Shippable Configurations)? 
  • Is Manufacturing / Contract Manufacturer ready to 1st Production Build? 
  • Are all product components available to start 1st Production Build? 
  • Are resources and equipment available? 

Input 

Marketing 

  • MRD (remains a living document after the Planning & Specification Stage Review but with limited changes expected) 

Service 

  • Serviceability objectives 
  • Product Service Plan 

R&D 

Engineering Prototypes 

  • Physical engineering prototypes 
  • Board tested and S/W package verified 

R&D Test 

  • Results of all defined Engineering tests according to test plan 
  • System test results 
  • Bug list 

Manufacturing 

  • Delivery of Pilot units to Atrica 
  • Pilot Build report including Final assembly & test yields 
  • Process validation documents for Manufacturability and Testability - Process Readiness 

Manufacturing Test 

  • Updated test S/W version (also made available to CM) 
  • Production test equipment updated after modifications 

Materials 

  • List of qualified vendors 

Finance 

  • Estimates of product GM in production (on a per component basis)
