HR Planning, Recruitment, Selection and Training
This complete preview comes from the Functions and Evolution of Human Resource Management unit. It introduces the core language, shows the method in context, and gives you a real example of the lesson quality before you create an account.
The HR Cycle
People are typically a business's largest cost and its most important source of competitive advantage — but only if the right people are in the right roles with the right skills at the right time. This subtopic introduces the core functions of the HR cycle and the soft-HRM versus hard-HRM philosophical divide. After this lesson, you will be able to trace the full employee journey from workforce planning through to appraisal, distinguish internal from external recruitment, and contrast treating people as assets to develop (soft HRM) with treating them as a cost to manage (hard HRM).
Workforce Planning
Forecasting a business's future staffing needs (numbers and skills) so recruitment/training can be planned ahead of demand.
Recruitment and Selection
Internal recruitment (promoting/moving existing staff) vs external recruitment (hiring from outside), guided by a job description (duties/responsibilities) and person specification (required skills/qualities). Selection methods include interviews, tests, and assessment centres.
Training and Appraisal
Induction orients new staff; on-the-job and off-the-job training develop skills. Appraisal reviews performance to guide development, promotion, or — where necessary — dismissal/redundancy decisions.
Soft HRM vs Hard HRM
Soft HRM treats employees as valuable assets to be developed and motivated. Hard HRM treats employees more as a resource to be managed efficiently, minimising cost — the two approaches reflect very different underlying philosophies of people management.
Common ErrorDon't assume internal recruitment is always cheaper or better — while faster and lower-cost, it also creates a staffing gap elsewhere and limits the fresh skills external hires can bring in.
Scenario
A business following a soft HRM approach invests heavily in staff training and development even during a quiet period, viewing employees as a long-term asset — while a hard-HRM competitor cuts training spend immediately to reduce costs.
Practice QuestionExplain one advantage and one disadvantage of internal recruitment compared to external recruitment.
