The Planning Process

supply and demand, but for talent

Workforce planning starts with understanding where the organization is today and where it needs to be. You analyze the current workforce (supply), forecast future needs (demand), identify gaps, and build strategies to close them. The forecasting method you choose matters.

Trend Analysis

Uses historical data to project future needs based on patterns over time

Ratio Analysis

Ties headcount to a business metric like revenue per employee or patients per nurse

Regression Analysis

Statistical method that predicts staffing needs based on multiple variables

Delphi Method

Anonymous expert panel reaches consensus through multiple rounds of feedback

Nominal Group Technique

Structured group meeting where members independently rank priorities then discuss

The 9-Box Grid

The 9-box grid plots employees on two dimensions. The horizontal axis represents current performance. The vertical axis represents future potential. Each employee lands in one of nine cells, and that placement drives development decisions.

Succession vs Replacement Planning

Succession planning is NOT replacement planning. Succession develops multiple candidates; replacement identifies immediate backups.

Succession Planning

  • Long-term and strategic
  • Develops multiple candidates
  • Includes coaching and mentoring
  • Builds leadership pipeline

Replacement Planning

  • Short-term and reactive
  • Identifies one backup per role
  • No developmental component
  • Emergency coverage only

Exam Traps

9-Box Grid Measures Performance × Potential

The grid always uses two axes. Performance (what someone has done) on one axis and potential (what someone could do) on the other. If a question asks about a third dimension, it is not the 9-box.

Succession Is NOT Replacement

Succession planning develops a bench of multiple candidates over time. Replacement planning identifies a single immediate backup. The exam deliberately conflates these.

Grid Interpretation Questions Are Common

Expect a scenario where you must place an employee in the correct box based on performance and potential ratings. High performance but low potential goes in a different box than high potential but low performance.

Succession = Develop

Succession develops multiple candidates over time. It is proactive and long-term.

Replacement = Backup

Replacement identifies who steps in tomorrow if someone leaves. It is reactive and immediate.

1
Succession Planning

You are training multiple pieces to play key squares on the board. A pawn could become a queen. A knight could take over a bishop role. You invest time developing each piece so that no matter which one falls, someone else is ready to step up.

2
Replacement Planning

You simply know which piece moves to which square if the queen falls. No training, no development. Just a list of who goes where in an emergency.

3
The 9-Box Grid

Imagine a tic-tac-toe board. The bottom axis is performance (low to high). The side axis is potential (low to high). Each employee lands in one of the nine squares. Top-right is your future star. Bottom-left needs attention.

4
Forecasting

You look at the board and predict how many pieces you will need next season. Trend analysis looks at history. The Delphi method asks expert judges. Ratio analysis ties headcount to a business metric like revenue per employee.

Succession = develop. Replacement = backup.
