CACI Limited Testimonials

"CACI were able to bring deep knowledge on device testing onto the nPower team across both SMETS 1 and SMETS 2 technologies and have been a great asset on the nPower Smart Metering Programme. In helping scale our test operations, CACI quickly deployed test leads, device testers and test analysts with the right mix of skills in SMETS 2 and SMETS 1 device testing. Their experience of smart meter testing coupled with their knowledge of the full protocol stack including Zigbee, GBCS, GBZ (DLMS), GBT, DLMS/COSEM enabled them to make a big impact on the test programme from the start. They have played a key role in test strategy development, test execution and test analysis as well as training and the upskilling of other nPower team members. Their skills in capturing, decoding, interpreting and analysing device (ESME, GSME and PPMID/IHD) logs, Comms Hub (CHF and GPF) logs and Head End System packet traces in addition to their understanding and use of GFI (GIT for Industry) for testing of remote (SRV) and local (HAN only) commands has been critical to the success of the testing programme."

"CACI have been a trusted partner on our Smart Metering test programme for over 3 years where they provide a Smart Test Managed Service. Early on in the service CACI were able to innovate and implement Agile test approaches into delivery teams and bring expert test resources onto the programme. They have deep experience on the HAN testing across Zigbee protocol as well as GBCS and DLMS/COSEM and the Sensus FlexNet WAN testing approaches as well as the testing of our operational and business support systems. Their knowledge of device testing (CH, ESME, GSME, IHD) as well as the DCC industry request commands and their operation is extensive. CACI run our testing programme across PIT, SIT and UIT and provide a people interface into the DCC supporting our own Arqiva resources across reporting and cross DCC party working and support of energy suppliers. They work very closely with us, using a single team mentality where they take on the challenges, shoulder the risks and when the test programme is under extreme pressure they make sure Arqiva deliver their commitments to the DCC."
