Human Resource Management
Strategic HRM: Hiring and Workforce Composition
An organization can't carry out a strategy with people it hasn't hired, can't keep, or hasn't developed. That's why human resource management is strategic. This section maps the HR function, and shows who really makes most people decisions. We'll plan a workforce, and look at four ways to close a staffing gap. Then job analysis, the foundation everything else rests on. We'll see how recruitment and selection work, and what the evidence says about interviews. Then onboarding, and how to measure the cost of turnover. One idea runs through it all. Hiring is a prediction, and some methods predict far better than others.
What HRM Is
A Relationship, Not Just a Transaction
Human resource management is the function responsible for acquiring, developing, rewarding, and retaining people. It's also responsible for the employment relationship itself, and that phrase deserves attention. Employment isn't just labor exchanged for pay. It's a continuing relationship. It's governed by law, by written and unwritten expectations, and by how each side treats the other. HR designs the practices that create, maintain, and when necessary, end that relationship. It's strategic when it connects to what the organization is trying to do. The key idea here is the shared responsibility model. Most HR decisions are made by line managers. A line manager directs the employees who produce the organization's goods or services. The line manager interviews, sets expectations, assigns work, gives feedback, and writes the appraisal. HR designs the interview format, trains interviewers, keeps records, advises on the law, and steps in when needed. So a manager who believes HR handles people problems has misunderstood her own job.
Functional Areas
8 Areas of HR Work
The work of HR can be mapped as eight functional areas. Workforce planning decides how many people, with which skills, the organization will need. Recruitment and selection attract candidates, and choose among them. Onboarding brings new employees in, and sets expectations. All three are covered in this section. Training and development builds skills for now and later. Its motivational use comes in section ten point two. Performance management sets standards, evaluates results, and gives feedback. Compensation is the pay and benefits given for work. Both appear in section ten point four. Employee relations covers communication, discipline, and complaints. Unions and bargaining get chapter eleven. Compliance makes sure the organization meets its legal obligations as an employer. That's section ten point three. The areas are linked. Weak selection produces performance problems the appraisal system must handle. And a poorly designed pay system undermines the recruitment that came before it.
Workforce Planning
Kestrel Supply: Finding the Gap
Workforce planning forecasts the future need for people, and the future supply. Then it decides how to close any gap between them. It has three steps. First, forecast demand from business plans. A new market, a new product, or a change in technology changes the work to be done. Second, forecast internal supply from the current workforce. Adjust it for attrition, losses through resignation, retirement, or other separation, and for moves between jobs. Third, identify the gap between demand and internal supply. Here's an example with constructed figures. Kestrel Supply is a fictional regional distributor. Its plan needs one hundred forty warehouse and delivery employees next year. It has one hundred twenty now, and its records suggest twelve will leave. So internal supply is one hundred eight, and the gap is thirty-two.
Closing the Gap
4 Responses, and the Default
There are four responses to a gap. The organization can recruit, hiring from outside. It can develop, training and promoting current employees into the needed roles. It can redesign the work. Change the process, technology, or job content, so fewer or different people are needed. Or it can reduce demand. Scale back the plan, delay the expansion, or use contractors and outsourcing. Here's the observation that matters. Recruitment is chosen by default. A manager with a gap reaches for a job posting, because it's familiar. The skipped question is whether another response would be cheaper, faster, or better. At Kestrel, redesigning the loading process might close a third of the gap. Promoting drivers into dispatch roles might close another portion. The rest might be recruited. Recruiting all thirty-two without examining the alternatives would be the default, not necessarily the best answer.
Job Analysis
The Foundation of the HR System
Job analysis is the systematic study of a job. Its tasks, its conditions, and what it takes to do it. That means the knowledge, skills, abilities, and other characteristics it requires. Information comes from observing the work, interviewing job holders and supervisors, questionnaires, and records. It's the foundation of nearly everything else. Selection criteria, interview questions, standards, and often pay grades. So a weak job analysis creates exposure at every later stage. Without knowing what the job requires, you can't show your criteria relate to it. Decisions become hard to defend. Two documents result. The job description states what the job does. Its purpose, main duties, reporting line, and conditions. The job specification states what a person needs. Knowledge, skills, abilities, and qualifications. Every requirement must be necessary, not merely desirable. Requiring a four-year degree people don't need, or ten years of experience where three will do, narrows the pool. It also creates legal exposure, since a requirement unrelated to the job may fall harder on some groups.
Recruitment
Attracting a Qualified Pool
Recruitment attracts a pool of qualified candidates, from internal or external sources. Internal recruitment fills vacancies through promotion and transfer. It's cheap and fast, and the candidate is known. It rewards existing employees, which supports retention. But it limits the pool, and brings in few new ideas. External recruitment uses postings, agencies, campus and community outreach, professional networks, and referrals. It brings a wider pool and new skills, at greater cost, and with more uncertainty. Match the source to the job. Scarce skills may need specialized channels. Many routine roles, broad advertising. Employee referrals have a well-known trade-off. Their yield is good. Candidates are better informed, referrers want a good fit, and it's inexpensive. But people tend to know people like themselves. Heavy reliance on referrals reproduces the existing workforce. That's an organization-level tendency, not a verdict on any one referral. Keep referrals as one source among several. A realistic job preview describes a job's demanding and unattractive parts, as well as its attractions. Candidates who know what to expect are less likely to leave in the first months.
Selection as Prediction
Valid, Reliable, Job-Related
Selection is choosing among candidates. It's best understood as prediction. From what it can observe now, the organization forecasts who will perform best in the job later. Three concepts describe how well a method does that. Validity is the degree to which a method actually predicts job performance. Reliability is consistency. Does the method give the same result when repeated, or used by different assessors? A method whose score depends on who runs it, or what day it is, can't be valid. Job-relatedness is whether it measures what the job analysis shows the job requires. A valid, reliable, job-related method is more effective, and more defensible if challenged. Research has compared methods by how well they predict later performance. A widely cited nineteen ninety-eight review by Frank Schmidt and John Hunter combined decades of studies. A twenty twenty-two reanalysis by Paul Sackett and colleagues lowered some estimates, and raised structured interviews. Since the numbers differ between reviews and jobs, the comparison here stays relative.
Table 10.1.1
7 Selection Methods Compared
Here's how seven methods compare, in relative terms. Structured interviews rank among the highest in validity, at moderate cost for design and training. Work sample tests, built from the job's actual tasks, predict well for those tasks. General cognitive ability tests are moderate to high overall, at low to moderate cost. But group differences in average scores create selection-rate differences, and legal exposure. Section ten point three covers that. Personality inventories are modest, vary by job and trait, and can be faked. Reference checks are modest, since candidates choose their referees. Resume screening is a necessary filter, but a modest predictor. And the unstructured interview predicts poorly, yet it's the most widely used method. Why? Interviewers form an impression within minutes, look for confirmation, and feel certain. That confidence doesn't track accuracy. The format rewards likability and fluency, which matter in some jobs, not others. Combining methods helps. The strongest packages pair a structured interview with a work sample, or a validated ability measure.
What Structure Means
Turning a Conversation Into a Measurement
A structured interview asks every candidate the same job-related questions, in the same order. Trained interviewers then score the answers against defined criteria. Each element has a job. Identical questions make candidates comparable. The same order means no candidate benefits from a more favorable sequence. Defined scoring, often with example weak, acceptable, and strong answers, replaces impressions with a standard. Each interviewer records scores before discussing them, so a forceful colleague can't sway the group. Trained interviewers understand the criteria, and the common biases. Questions come in two kinds, both drawn from the job analysis. Behavioral questions ask what the candidate did in a past situation. Situational questions ask what they would do in a described one. Structure isn't rigidity for its own sake. It's what converts a conversation into a measurement.
Onboarding and Turnover
Keeping the People You Chose
Onboarding integrates a new employee. Setup, introductions, job training, and above all, setting expectations. The first weeks and months are when a new hire decides whether the job is what was promised. Early leavers often found reality differed, expectations were unclear, or no one helped them settle in. A plan with defined early expectations, a named person to ask, and manager check-ins addresses those causes. And the realistic preview and the onboarding expectations should tell the same story. The turnover rate is separations in a period, divided by average headcount, as a percentage. With constructed figures, thirty separations against an average headcount of two hundred gives fifteen percent. Separations are voluntary, when the employee leaves, or involuntary, when the employer ends it. Turnover is functional when the leavers are affordable losses. It's dysfunctional when high performers or scarce skills leave. So an acceptable-looking rate can hide a serious loss of the wrong people. Separation, vacancy, replacement, and ramp-up costs often appear on no budget line, so they're underestimated. Bureau of Labor Statistics data allow industry comparisons. But the real questions are who is leaving, and why.
Case Vignette (Composite)
3 Impressions, 3 Different Candidates
Here's a composite case. The organization and the people are fictional. A hiring panel at Norvale Logistics interviews four candidates for a customer coordinator role. There's no set list of questions. Ibrahim, Wendy, and Carlos each chat with each candidate, and form a view. Ibrahim prefers the most personable candidate. Wendy favors the one with the most impressive previous employer. Carlos thinks both are unsuitable, partly because one didn't seem confident. Three panelists, three conclusions from the same four conversations. They settle it by seniority. They could accept that, reconvene with fixed questions, or add a short work sample. The role has been vacant for six weeks, so the trade-off is speed against decision quality. The candidates weren't treated alike. Different questions, different orders, and different unstated standards. A job analysis would have shown what a customer coordinator actually does. Questions could follow from it. How did you handle an upset customer? How would you prioritize competing requests? Each panelist would score before discussion, so the debate would be about evidence, not impressions. And a short sample task, like answering a realistic customer email, would show the actual work.
