> Hiring more staff always slows progress in the short term. It has a habit of making late projects later.
Brooks law applies to late projects, not new ones. If you have good estimates you can determine if you need resources early on.
All a lot does depend on the size of the project. If it's something that will take 12 months or longer than extra hires definitely wouldn't have that affect. Depending on the hire and the work required, you can shorten than time frame significantly too.
However I do agree that hiring isn't a silver bullet. This is why I suggested "hiring" as one of many outcomes that can be considered rather than the preferred outcome in all situations.
> I understand you’re desire for an FTE to be a meaningful measure, but imperially that’s not true. As I said several times effort estimates can be used, but after deciding to add staff progress slows down for a while. So, using effort estimates you would reduce progress over the next 3 months before expecting a longer term increase in rate of accomplishment.
This is where another piece in the jigsaw comes into play - an employee might not be 1 FTE. They might be part time, might have leave booked, might have commitments on other teams (effectively part time from your perspective) or might be a new hire so need upskilling time. Those are just a few common examples - I'm sure you can think of others.
This is why I keep reiterating my point about calculating your figures based on work required from FTEs. By talking about new hires as you are, you're again thinking about "teams" rather than "work required". When you look at work required then you can use your team as a variable in the calculation and instantly estimations become easier.
I'm undoubtedly explaining the process poorly but I do strongly recommend you read some books or articles online about managing projects and teams using (for example) agile methodology - even if you've already worked in places that employ scrum (again, for example). You could potentially really improve how you estimate work which in turn will improve how you manage your team. From personal experience, I've been a manager for a number of years and have found my skills really improved as I've adopted those lessons too.
