A forecasting method that extrapolates from historical organizational indices
Trend Analysis
Ratio Analysis
A quantitative method of projecting HR demand by analyzing the relationship between an operational index and the number of employees required
Quantitative methods of forecasting
trend, ratio and regression analysis
Qualitative methods of forecasting
envelope/scenario planning, impact analysis, Delphi technique and the nominal group technique
5 steps of conducting an effective trend analysis
- Select the appropriate business/operational index
- Track the Business Index over time
- Track the workforce size over time
- Calculate the Average Ratio of the business index to the workforce size
- calculate the forecasted demand for labour
Regression Analysis
Presupposes that a linear relationship exists between one or more independent (cause) variables, which are predicted to affect the dependent (target) variable (like future HR demand for personnel - number of personnel required)
Linearity
refers to the observed relationship between the independent and dependent variables (if met, can use for demand forecasting)
Envelope/Scenario Forecasting
projections, or multiple-predictor estimates, of future HR demand based on a variety of differing assumptions about how future organizational events will unfold
Forecasting method in which past trends are analyzed by a panel of experts to predict future HR demand
Impact analysis - relies on subjective expert judgements
Delphi Technique
a process in which the forecasts and judgement of a selected group of experts are solicited and summarized in an attempt to determine the future HR demand.
Process of Delphi technique
a carefully designed program of sequential, individual interviews interspersed with feedback on the opinions expressed by the other participants in previous rounds.
Steps of Delphi technique
`1. Define and Refine issue in question
- Identify the experts, terms, and time horizon
- Orient the experts
- issue the first-round questionnaire
- Issue the first round summary and second-round questionnaire
- Continue issuing questionnaires
Disadvantages of Delphi
- results cannot be validated statistically - rely on individual knowledge and commitment of experts
- higher time/costs
- common professional training might prevent development of innovative courses of action
- if insufficient attn has been paid to developing criteria for ID and selection of experts, experts may lack the sufficient expertise or info for meaningful contribution
Long-run forecasting technique utilizing expert assessments
Nominal Group Technique
Why does NGT “reduce potential for dominance, personal attacks, defensive behaviour”, etc?
Because each estimate is considered to be the property of the entire group and to be impersonal in nature
