What is succession planning?

When a key person leaves, whether they resign, are promoted, or retire, the cost to the organisation is often more than an empty seat. The knowledge they carried goes with them. Projects they led can stall. The team is left wondering who will step up and what happens next. Succession planning is the practice of preparing for that day before it arrives. It means identifying which roles are critical to your business, choosing people who could one day step into those roles, and developing those people so that when the moment comes, you are not starting from zero. Done well, it reduces risk, keeps operations running through change, and gives your people a clearer sense of where they could go. This post explains what succession planning is, what it typically involves, and why more organisations are making it part of how they manage talent.

Succession planning usually starts with a simple question: which roles would hurt the business most if they were suddenly empty? The answer might be senior managers, heads of department, technical leads, or people who hold critical relationships with clients, partners, or regulators. Once you have a shortlist of critical roles, the next step is to name one or more potential successors for each. These are people who, with the right development, could step into the role in the future. Then you track how ready they are. Readiness might depend on training, experience, exposure to the role, or specific skills they still need to build. Many organisations link succession plans to development goals so that potential successors are not just names on a list but people who are actively being prepared. HR and line managers typically own the process, with leadership deciding which roles and people matter most and reviewing progress over time.

The main reason organisations do succession planning is to avoid being caught off guard. Without a plan, a sudden resignation or retirement can mean a scramble to hire from outside, a gap in delivery while the role is empty, or someone promoted before they are ready because there is no one else. With a plan, you have a clearer picture: who could step up, how ready they are, and what support they might need. That does not mean every move is predictable, but it does mean you are not starting from scratch when change happens. There is a second benefit that often gets overlooked. When people are named as potential successors and see that they are being developed for something, they tend to get a clearer path and a stronger reason to stay. Succession planning can be a way of telling your best people that they are valued and that the organisation is investing in their future. That helps with retention as well as with readiness.

Succession planning works best when it is part of how you run the organisation, not something you do once a year and then leave in a spreadsheet. If it is invisible or buried in a file that nobody opens, it will not shape behaviour or decisions. People need to see it. Staff who are potential successors should know where they stand and what they are being developed for, so they can work with their managers on the right experience and training. Managers and HR need easy access so they can review and update plans, add or remove names as people move, and keep readiness up to date. When succession is visible and discussed regularly, it becomes a real part of talent and risk management rather than a tick-box exercise. That often means giving it a clear place in the tools people use every day, so that checking or updating a succession plan does not feel like a separate, forgotten task.

In Careersome, succession planning sits alongside recruitment, performance, pay, leave, engagement, and offboarding in one system. You can define critical roles, add potential successors, track readiness, and link plans to development goals. We added succession planning to the platform and in March 2026 we made it easier to find and use. My Succession Planning now appears in the dashboard sidebar for managers, HR, and staff. If you are a potential successor, you can open it from the main menu and see all the plans you are part of in one place: position title, current holder, target date, priority, and how many candidates are in the pipeline. No need to hunt through menus. For managers and HR, the same link gives a quick view without leaving the rest of your work. If you would like to see how succession planning works in Careersome for your organisation, you can book a demo. For the full list of changes in this release, see our release notes.
