The person who was already ready

A friend of mine had been doing most of the job for a year. Covering the gaps, helping the new starters, holding the team together on the days her manager was pulled elsewhere. So when the role finally opened up – her manager moving on – everyone assumed, including her, that it was hers.

They hired someone from outside instead. A perfectly decent candidate, as it happens, with a slightly shinier CV and good connections. My friend was gracious about it in the meeting. She did the right thing: congratulated the new arrival, offered to help them find their feet, and genuinely meant it. Then she updated here CV, polished the ever needed LinkedIn profile and started taking recruiters' calls. One month later she was gone – to a competitor, into more or less the job she'd just been passed over for, with a bigger salary and a lot more influence on how to get the job done.

Her manager was baffled, disappointed, confused, sad, probably a little miffed too. She'd seemed so settled, like someone who would never up-sticks and move on. My friend, moving on, also left a giant gap in the business – the knowledge, the process experience, the relationships and the technical skills. Panic set in.

But isn't that the human condition; we don't appreciate people until they've gone?

When I hear someone use the words succession planning, the boring sounding phrase used by leaders, managers, consultants and HR, I think of my friend. Succession planning sounds remarkably like the sort of thing that had nothing to do with what happened with her – a kind of formal HR exercise, a grid of little boxes, a specialist activity you'd need a framework and an away-day to complete.

And that's exactly the big misunderstanding of it. If you strip away the technical term and the ceremony, succession planning is wonderfully simple: knowing your people well enough to see who's ready for what's next, and knowing your work well enough to see what would hurt if it suddenly went uncovered. The manager who lost my friend hadn't fallen down on some process known only to the upper echelons. She simply hadn't been paying attention.

Start from the absolute reality of work: people will leave. Not as a risk to be added to every risk register, nor hovered over every day, nor fretted about – but as the simple act of having a plan. The way you might build a plan for a long road trip through Britain.

The good managers assume movement will happen and think ahead of it; they don't wait for the gap to open before wondering who might fill it. What's remarkably surprising to me is how often a departure lands as a shock when the manager had three months' notice – longer, really, if they'd been paying attention.

There's a confusion about the role of succession planning. It's tempting, especially for kind managers, to feel you work for your people – that the job is to keep them happy. You don't, quite. You work for the organisation, and part of that responsibility means holding two things at once that always pull against each other: real genuine care for the people in front of you, and real genuine responsibility for the work continuing on when they move on. Succession planning is simply how you look after the second without letting go of the first.

And here's the part most people miss. Done well, succession planning is retention, in fact, I'd argue it's the primary source of retention. When people can see a path ahead of them, when they're being developed and trusted with more and moving toward something they can see, they tend to stay. You never have to say the words "retention" or "succession planning" for it to work; the developing is the message. The growth is the signal. The trust is the commitment.

The reverse is just as true, and often far more expensive. Bring someone in over a person who was ready, and you've told them – and everyone else who's watching – exactly where they stand. External hiring has its place, for sure. But going straight to market as a default when someone inside was ready, is a cost that never appears on a spreadsheet, and the overlooked person tends to walk out of the door about a month later with a freshly updated CV.

None of which means shoving everyone toward management. In fact, don't. Plenty of people grow by going deeper rather than upward – more expertise, more scope, more ownership of the hard and interesting work, more exploration of creative challenges, more technical depth, without ever wanting a team to run. Succession planning isn't a ladder; it's more like a conversation – a clever matching of what the organisation will need next against what each person actually wants next.

Which is very optimistic and insightful, when you think about it. It means you can only really do it if you know your people, and your work, well enough. That is the whole of succession planning, and it fits into a single question: who on your team is ready for their next step? If you can't answer it, or you run dry on ideas after a name or two, that isn't a mark against you. You haven't failed the great succession planning test. It's just useful information and a signal – often that you don't yet know your people, or your work, quite as well as you'd maybe thought you did.

Succession planning needs no tooling at all, nor a framework, nor a complicated app. A sheet of paper and a decent pencil is plenty. Draw a line down the middle. On one side, the roles and responsibilities that would genuinely affect your ability to turn ideas into something valuable for the business if they went uncovered tomorrow. On the other, the people who have both the ability and the appetite for more. The gaps between the two sides are where your important work lives. Where you have a person who could fill the gap, you could act on that this week – a tougher project, a bit of on the job training, an opportunity you know they'd grow from. And if either side of the page looks empty, that's not a verdict on you either. It's a subtle nudge to get out there and study the work, and the people, and to work on completing the page.

That, in the end, is all succession planning is. Not a framework, not an initiative, not something to be filled in on a spreadsheet. Just the everyday activity of an effective manager – the act of paying attention. It protects the work, it grows your people, and, done consistently, it means the person who's already ready never has to go somewhere else to be seen.
