It is still rare for a company to explicitly decide to devalue quality and mid/long term costs, and typically it is a side effect of incentives.

Obviously 'fake Agile' is an industry wide problem here. But if teams cannot control their capacity expectations, it will always devolve to this

'slack' was a poor term to use IMHO, but it is here.

In companies that care about med/long term survival and success can fix this over time.

Selling it as derisking on strategic and initiative time scales is one way that can help.
