A common theme of many of the "gripe" posts and threads on TMC seems to be that Tesla often does a poor job internally of communicating with customers. I stumbled across an article recently which stated that Elon Musk decided early on to have Tesla's ERP (enterprise resource planning) software custom built from scratch by employees - rather than purchasing a package from one of the big vendors such as Oracle, SAP, Microsoft etc. Another common theme on these boards is that Tesla's internal culture seems to lend itself to leaving bugs un-fixed in the software which runs the actual vehicles and interfaces with drivers. So this got me wondering - perhaps Tesla's home-grown ERP software is also buggy, creaky, poorly developed and incomplete - and I wonder if that might contribute at all to some of the communication issues. I could be 100% wrong on this - it's mere speculation.
