All I would say – is it depends. As picked up in other threads, should ideally separate out e.g. QA from QC from Technical etc, but in the dim and distant past I was a Technical Manager, who happened to run a lab (mainly physical testing) and had a regulatory (QA) function (e.g. writing/controlling Technical Files – as well as writing SMs, SOPs, Specifications etc for transfer into QC). We were a small device orientated setup in a much larger pharma function. Sometimes you have to wear many hats.
