The challenge is that once the immediate fire is out, it's easy to simply leave things in a half-baked state. That accumulates as technical debt.
Thankfully, most of the instances where I have had to deal with this has been purely software and not affected the lives and comfort of operators on the floor like with Tesla. But I can see how this happens. Even if the 'tent' becomes a permanent installation, I hope they spend the time and money to improve it to the necessary working standards that employees deserve.
