Succession Planning with Org Charts: Protecting Key Roles

Why succession planning matters

Leaders resign, retire, fall ill or are recruited by competitors, often with little warning. Without a plan, the business either leaves a critical role empty while it recruits externally or promotes someone who is not ready. Both outcomes cost time, money and morale.

A succession plan does not guarantee anyone a promotion. It is a risk-management tool that helps the organisation recover quickly and gives promising staff a clear development path, which also supports retention.

Step 1: Identify critical roles

Start with your current org chart and mark the roles whose loss would significantly affect operations, customers, compliance or strategy. These are usually the chief executive and executive team, but not only them. A specialist engineer, a key account manager or the only person who understands a legacy system may be just as critical.

• How long would it take to fill this role externally?
• Does the role hold unique knowledge, relationships or licences?
• What happens to customers or revenue if the role is vacant for three months?
• Is the role legally required, for example a statutory officer?

Step 2: Assess the risk for each role

For every critical role, consider two factors: the likelihood that the incumbent leaves in the next year or two, and the impact if they do. Retirement plans, market demand for their skills and recent engagement signals all affect likelihood. A simple high, medium or low rating for each is usually enough.

Roles with high impact and high likelihood need attention first. Roles with high impact but low likelihood still need at least an emergency cover arrangement.

Step 3: Identify potential successors

Look at the levels directly below each critical role on the org chart and ask who could step up, either now or after development. Classify candidates by readiness, for example ready now, ready in one to two years and ready in three or more years. Aim for at least one emergency cover person and one longer-term successor for each critical role.

Look beyond the obvious reporting line. A strong successor for a finance leadership role might currently sit in operations or a regional business. An org chart that shows the whole business makes these sideways moves easier to spot.

Step 4: Close the gaps with development

For each named successor, agree what they need to become ready and plan how to provide it. Development is usually most effective when it combines real experience with support.

• Stretch assignments or acting-up periods in the target role.
• Exposure to board or executive meetings.
• Mentoring by the current incumbent or another senior leader.
• Formal training or qualifications where the role requires them.
• Documenting key knowledge, contacts and processes held by the incumbent.

Step 5: Spot structural weaknesses

Succession reviews often reveal problems in the structure itself. A department where the head has no capable deputy, a team with a single specialist, or a manager whose span of control is too wide to develop anyone are all structural risks. Sometimes the right answer is to create a deputy role, split a team or cross-train staff, not simply to name a successor.

Keep succession information confidential

Succession plans contain sensitive judgements about people's potential and their likely departure. Share them only with those who need to know, usually the chief executive, the HR lead and the relevant executives. Be careful about who can see draft charts that show successors or risk ratings.

This is one reason a private, browser-based tool is useful. In the dial369 designer you can save a separate version of your org chart for succession planning, use custom titles or notes on cards to mark critical roles and named successors, and export it for a confidential leadership discussion while your everyday chart stays unchanged.

Review regularly

Succession plans go out of date as people are promoted, leave or change their plans. Review the plan at least once a year, and after any restructure or major change in the leadership team. Each review is also a chance to update the org chart so it remains an accurate picture of the business.
