What do you mean by this? As in, people hate doing marketing or they don't understand how to advertise? Plus, a mistake can cost valuable data? Where are you losing data?
A mistake can mean - misconfiguring your target (wasting money on ads that won't give you an ROI), misconfiguring your 3rd party tracking (letting data like conversions go unaccounted for, or not having your auditing tags setup, meaning you show ads to fraudulent users that you otherwise wouldn't have to pay for), etc.
Alternatively, one place to manage creatives and language as well as targeting for each campaign might be helpful as we use google sheets, excel and Trello for this now.
