Product Hand-Over ChecklistObjectives are to ensure that:• A well-defined development process was followed for the
product• The product meets its technical specifications,
documented by Qualification Test Results (QTRs) and Acceptance Test Results (ATRs)
• The product can be supported and maintained after hand-over
• The product is successfully installed on-site• The logistic support development for the product is in
process
• Final document release planned for May 2017

Product Hand-Over Checklist(example)
• Forms the basis for the delivery of products and planning of integration & verification activities
• Considers:– Sequencing of implemented functionality– Scale: How many Dishes / Stations deployed and when– Integration of MeerKAT Precursor into SKA1-MID
• Sequential process – early retirement of risks• Achieved by specifying “Array Assemblies”• Currently at Rev 5, released by Dec 2016
Roll-Out Planning
• Described by:– Date
• When all required products have been installed, i.e. not necessarily integratedinto Telescope System
– Number of Dishes / Stations– Array Capability → Determines back-end Element functionality– Key Engineering Goals
• Array Assemblies used by AIV Contractor– Verification of Level-1 (System Level) Requirements
• Array Releases used by Science Validation Team– Validation of Science Requirements
Array Assembly
• Multiple ITFs– At Element Level or lower
• All over the world. Rely heavily on simulators/emulators. No AIV involvement.
– At System Level• End-to-End line-up of Level-2 products
• System ITF used for:– System Level Design Qualification– Verification of interfaces between Level-2 products– Debugging, troubleshooting, development work, etc– Testing of hardware/firmware/software upgrades during Constr. Phase– Knowledge transfer (between contractors, engineers, AIV Team, etc)
