This article didn't price in opportunity cost. It isn't just a $150k/annum expense on an individual SRE salary. One should consider the HR time to source candidates and time to interview. It would include the time your tech team is brought into system design and security meetings, time your tech leads spend in 1:1s. It may involve time for your CTO to document the part of your systems for enterprise customers who require full architecture details for their requisition process. It may involve time for your product team, business analysts or executives to be retrained on software that is unfamiliar and non-standard to them. Most of these activities slow down critical parts of your business which could be focused on generating revenue. A fair accounting should attempt to estimate these costs. Consider: if you didn't disrupt the business and instead spent the same effort on revenue generating product features then how much could you earn?
