I think it's been stated in this thread, and I learned it reading the comments on HN, but consultants are not hired to optimize processes but instead to provide decision insurance. If you take a big risk by yourself and it goes poorly, your job and reputation are on the line. If you hire a consulting firm that advises you take the risk, and report that the risk is properly characterized and understood, and then it goes wrong - well sometimes the best laid plans fall victim to circumstance.
I submit my thesis. The PE/consultant class. A crust of slime buoyed about on the waves of capital to provide cover for the horrors underneath.
Hospitals are opex constrained for things that don’t generate revenue. The operations run lean and are focused on operating. There’s no bench in finance or IT or whatever to figure stuff out. Enter the consultant.
Consulting is often tied to capital spend and most importantly they go away when the job is done.
Like someone else pointed out, if people are hiring them in order to provide cover for decision making, then maybe the whole thing being a charade is the point.
I also am aware of a situation where a pair of business consultants who were meant to be assisting with a software project were diverted (at full rate 1200/day) to assisting with redecorating an office.
I was directly involved, oppositionally, to a pair of business analyst consultants who tried to get a customer of mine to change their (admittedly terrible) vendor selection by repeating security concerns over and over again in the meeting. They never actually got to the point of analysing said terrible vendors terrible integration practices or costing up a migration path. They just banged on about security and contacted us separately after the meeting asking for more details about the security situation.
Basically you get out of it, what you want to get out of it. It depends on the consultant, their education, and the terms of their engagement. I don't know if statistics would be useful in this scenario or how you would control for wildly different outcomes.
You are now a fully trained management consultant. (Alan Johnson, Peep Show)
With that being said, consultants have no skin in the game, and thier incentives are aligned more towards executive relationship management and seeking out new opportunities for revenue vs. achieving aspirational metrics that ultimately matter to a health system.
I work in medtech and a model that I am more hopeful for is attaching consulting servics with capital purchaes. (e.g. siemans, GE). This model puts skin in the game from the manufacturer as outcomes and ultimately future revenue is tied to being able to show improvement on key clinical, financial, and operational metrics.
Curious to see if this study design can be applied under this scenario (search for press releases regarding signed partnerhsips with medtech and examine a narrower set of outcomes identified in those press releases).
Afaik, their job is to give management the cover managment thinks it needs to do the things it wants to do or thinks it needs to do.
The article claims the study says the billions spent on management consultants didn't move any metrics significantly, other than a small negative change for stroke readmissions.
