I manage a technical team that's dramatically understaffed.
It's not about our processes or anything like that. It's really simply about too few hands that can do what we need to do. Plus those we have are relatively inexperienced.
Now my boss wants to give me additional resources to coordinate our work better, gather business requirements, etc. Basically they would be people with soft skills, not much technical knowledge. They would support the morale of the team, give it a bit more of "business perspective", etc. They wouldn't be able to solve tickets since they wouldn't be technically savvy.
I find the idea really strange. Our problem is a huge technical debt. We don't have the technical capacities to implement solid solutions, no matter how much we work and the idea is to get us someone who won't be any support in that but who will give us more of "business perspective". (We do understand business perspective and needs - we just can't support business to the extent expected since we don't have headcount).
My goal is to make my boss understand that a team in which all are good at managing, coordinating and talking to business but no one really has a clue about technicalities isn't the best IT team and won't deliver what business expects us to deliver. What arguments should I use apart from those listed here?
