I agree with you that in an organisation as large as the public sector, then there will be square pegs in round holes...people who are not good enough to do THEIR job.
But if that's the case, they need to be transferred pronto or let go!!!
Transferred, yes I agree (as I think is obvious); let go - not until a reasonable effort has been made at identifying and utilitising strengths. Quite aside from the fact that most of the organisations making up the civil and public service are large and broad enough to encompass and require a wide range of skills, you'd face a barrage of unfair dismissal claims if reasonable efforts were not made.
The reluctance of any union to allow forced transfers (ref: decentralisation) is a problem with part one of that option. If you're bad at your job and won't transfer 5, 10, 20, 50 or 100 miles well then the alternative is forced layoffs, on a case by case basis as some of them will have been better at the job they were in than others so giving 10 weeks redundancy across the board is a golden handshake to those who don't deserve it..
I doubt we'll fully agree on the decentralisation thing! I transferred to avoid it, and my job has since moved. I was rather good at it, of course, so naturally you're not finger-pointing my way.
Also, and this has to be acknowledged, If I'm crap at my techie office job, I can't complain if I'm told to go, with the line "but I'm a great orator so it's your fault for putting me in this position in the first place". Aptitude tests are used in the civil service to determine peoples suitability at a job originally. .
So that's what they're for!
Seriously, this is something which is horribly under-used. Aptitude tests are not used by Departments in assigining new / existing / promoted staff. I don't think they're even given the data. So Joe Bloggs, who's
brilliant with numbers isn't put in the payroll area with the complex numerical data they have to deal with; with his only-just-passed the analytical competence test, he's put in an area working on policy. And Mary Jones, who's got a degree in public administration and three years as policy development officer in an NGO but goes blank when faced with numbers more than 10, gets put in payroll.
Swap Joe and Mary; hey presto, the whole organisation works better.
There's room to move, rather than just fire, a lot of people and to raise standards just by strategic assignment.
Also, people generally 'know' if they're rubbish at their job, unless they're totally deluded, in which case they shouldn't be there, so why have they not applied for a transfer to a position to which they think they would be better suited? Complacency? Laziness? Giving up a cushy number where they can get away with poor performance? Close to home and put that above doing a job to be proud of?
Maybe some of the above, maybe really hopes that if they try really hard that's all that can be asked (even if they're still just not good), maybe afraid to rock the boat, afraid of being seen to be a trouble-maker / unable to cope (some of which latter, regrettably, are justified). Lots of reasons, not all of which necessarily reflect badly on the person.
Regardless of all these possibilities, it would take a hard-ass to ruthlessly cut people out of their position in order to rectify these issues, and does the public sector have enough of them that will ignore personal relationships and look at the scenario with the 'bigger picture' in mind ?
I doubt it, but I don't know.
I honestly don't think you even need to be ruthless - at least not very, and at least not yet*. A lot of managers know where their staff's strengths lie, and, if asked for an assessment of what type of assignment will suit both the person and benefit the organisation, would happily give it.
We're going to lose a lot of people through attrition (retirements, other leavers not replaced, etc) and non-renewal of contracts over the coming years. Most of us will have to take up additional workload / responsibilities, and it'll be in all our interest to see more efficient use of resources, especially including staff. If carefully presented, I could imagine a high level of buy-in to a scheme which tagged people's strengths for use in reassignments.
Whether it can or will be done is of course another question.
* Ruthlessness may well be justified for long-term underperformers after reasonable efforts have been made to fit them to roles for which they should be better suited.
