Demand Forecasting and HR Inputs

Organisations make workforce decisions based on anticipated demand for products, services, or projects. Accurate demand forecasting requires collaboration between business units and HR, as workforce availability and skills are key enablers of business plans.

For HR professionals, understanding what inputs to provide and how to interpret workforce data is essential for aligning manpower planning with organisational needs.

What Is Demand Forecasting in Workforce Planning?

Demand forecasting is the process of estimating the future workforce requirements to meet business objectives. It goes beyond headcount—it includes skills, capabilities, location, and timing.

HR provides critical inputs, ensuring that the organisation has the right people, with the right skills, in the right roles, at the right time.

HR Inputs That Support Demand Forecasting

1. Current Workforce Profile

HR provides data on:

• Headcount by function, role, and location

• Skills, experience, and qualifications

• Career progression and promotion timelines

This forms the baseline for forecasting additional requirements.

2. Attrition Trends

Analysis of past voluntary and involuntary exits helps forecast potential gaps in the workforce.

• Average tenure by role

• Exit reasons and patterns

• Impact of seasonal or project-based turnover

3. Internal Mobility and Succession Planning

HR insights on internal candidates available for redeployment or promotion help reduce reliance on external hiring.

• Successor readiness

• Internal transfer history

• Training plans for role transitions

4. Recruitment Pipelines

Information on ongoing recruitment and talent acquisition timelines informs realistic workforce availability.

• Open requisitions and time-to-fill

• Candidate quality and offer acceptance rates

5. Skill Availability and Gaps

HR tracks the organisation’s skills inventory and identifies shortages that could affect future demand.

• Core technical or functional skills

• Emerging skills required by the business

• Gap analysis reports
