My metrics are really simple - I don’t do staff augmentation. I get a contract (SOW) with a known set of requirements and acceptance criteria.
The only metrics that matter is it done on time, on budget and meets requirements.
But if Claude Code is generating “useless code” for you, you’re doing it wrong
And I assure you that my implementations from six years of working with consulting departments/companies (including almost four as blue badge, RSU earning consultant at AWS ProServe) have never gone unused.
