I too am in your situation, here is what I did. Partner with your ETL-GE and try to get a few hours each week off the floor to do DA things. In order to really take complete ownership of anything iOS/Mydevice this is a necessity to have some time you can dedicate to it. This includes running the iOS Equipment Control report as well as following up with any noncompliant (update needed) devices and devices that haven't been seen in a while/expired certificates (expired certs are
fun and involve CSC.) You can run the report as little as once a week or as often as you sit down at a computer to check Redwire or email, it is one of the more quick reports on Workbench depending on your device load, and my report checks up on 45 devices every time when you include Guest Service and PMT.
Personally, I "borrowed" a cheap clipboard out of TSC that I keep a recent iOS EC report on as well as the week's "Get Appy" and "Digital Deals" paper your ETL-GE should be updating each week on the board in TSC where all the metrics and stuff are. The problem with the iOS EC report is it only prints out the first 10 or 11 devices, so you may have to sort by "Devices with application issues" print that and then "Devices last seen >3 days ago" and print that. I find it helps me to keep all my DA stuff organized and in one spot. One report that's not on Workbench that you need to get from your ETL-GE is the list of what serial numbers correspond to what arbitrary device number (#1, #2, etc) because the serial number stickers on the sleds fade very quickly and all the Workbench reports go by serial number not store device number. This list helped immensely when my ETL-GE printed it off for me.
To be a driving force, it all comes down to educating the team. At the front, make sure your cashiers are educating guests on Cartwheel that aren't already using it. Encourage, but don't require them to use their personal devices to show them how Cartwheel works, but make sure they aren't being taken advantage of by the guest and delaying the transaction too much. Hint: Cashiers should educate but not let a guest require them to scan everything and give them the discount. Many cashiers at my store are eager to show the guests Cartwheel and use their personal phones because it earns them more savings. On the floor, you can partner with the SF TLs or whoever leads your huddles to make sure that when you can't be at the huddles someone is educating the floor team about the mydevices and letting them know what's on Cartwheel and promoting it to guests. Your ETL-GE should set up a store Cartwheel account that all the mydevices are logged into so that ideally, if a TM walks a guest to an item, that TM can say just from looking at the price in myWork "Oh, this is on Cartwheel! Do you know about that?".... and such.
Make sure your team across the store knows that they can come to you with any questions or for any information, establish yourself as the go-to person for everything myDevice. In order to really take ownership of the area you have to start with getting a complete understanding of how the processes work both on the TM and guest side so you can troubleshoot problems from both ends of the spectrum. If you're also doing updates, play around a bit with the new features so you can explain them to the team and get them excited for it. My team was most excited for SUBT/STO/QMOS to be added and the "scanner ready" beeping.
If you have any other specific or general questions about being a DA you can always PM me, I've become really familiar with the processes lately.
@RunForACallBox is also one of the DA's on this forum if my memory serves me correctly.
Edit: so is
