Data Inputs Required for Manpower Planning

Effective manpower planning depends on accurate and relevant data. Without reliable inputs, workforce plans become assumptions rather than informed decisions. HR plays a central role in collecting, validating, and interpreting workforce data to support manpower planning.

This article outlines the key data inputs required for structured and effective manpower planning.

Why Data Is Critical in Manpower Planning

Manpower planning aims to align workforce supply with organisational demand. Data enables HR to:

• Understand current workforce capacity

• Forecast future manpower requirements

• Identify workforce gaps and risks

• Monitor workforce effectiveness over time

Reliable data improves planning accuracy and decision-making.

Key Data Inputs for Manpower Planning

1. Current Workforce Data

This provides a baseline understanding of existing manpower.

• Headcount by role, function, and location

• Employment type (permanent, contract, temporary)

• Experience levels and tenure

2. Skills and Competency Data

Skills data helps assess workforce capability and readiness.

• Skill inventories and proficiency levels

• Certifications and training records

• Critical and scarce skills

3. Attrition and Movement Data

Understanding workforce movement helps anticipate future gaps.

• Historical attrition rates

• Internal transfers and promotions

• Retirement timelines

4. Business and Operational Data

HR aligns manpower planning with business activity.

• Business growth or expansion plans

• Project timelines and workloads

• Production or service volume forecasts

5. Recruitment and Hiring Data
