The Staffing Function and Its Critical Importance
Why recruitment, selection, and placement determine the ceiling on everything else an organisation can do
Summary: The staffing function determines the capability that an organisation will have available to execute every other function. Recruitment, selection, placement, and orientation are not administrative tasks; they are the mechanism by which a strategy becomes executable. This post examines what staffing is, why it sits at the centre of organisational performance, how the process unfolds, and what the historical record shows. Each section addresses the five core elements — why, what, when, who, and how — then closes with a blog analysis of pros and cons grounded in paired international and emerging-market cases.
Introduction — The Function That Determines Everything Else
In 2018, the Australian mining company BHP disclosed that it had spent over $1 billion on recruitment and training between 2012 and 2017, only to discover that two-thirds of new hires in remote operations had left within two years. The company’s own post-implementation review identified the cause not as a failure of operational planning or financial management but as a failure of staffing: the selection criteria prioritised technical qualifications and overlooked the lifestyle fit and psychological resilience required for isolated fly-in-fly-out work. The financial loss was substantial. More importantly, it demonstrated that no other management function could compensate for a staffing failure of that kind.
The staffing function is defined by Harold Koontz and Cyril O’Donnell in Principles of Management as “the managerial function of filling and keeping filled the positions in the organisation structure.” The definition contains two distinct activities that are frequently collapsed into one: filling (recruitment and selection) and keeping filled (placement, orientation, retention). The staffing function is not complete when a candidate is hired. It is complete only when the right person is doing the right work in the right role over time.
This post examines four interlocking components of the staffing function:
- What staffing is — and how it differs from the broader field of human resource management
- Recruitment — the sourcing of the candidate pool from which selection will be made
- Selection and placement — the process by which candidates are chosen and positioned
- Onboarding, retention, and cost of failure — the complete cycle, including what happens when it goes wrong
The analysis draws on two academic traditions. The first is the classical management tradition established by Koontz and O’Donnell, which treats staffing as one of five managerial functions alongside planning, organising, directing, and controlling. The second is the strategic human resource management tradition associated with David Ulrich, which examines how staffing decisions create or destroy organisational capability. Where the two traditions conflict, the cases in this post favour the capability-based reading.
Chapter 1 — What the Staffing Function Is and How It Differs from HRM
Definition. The staffing function is defined by Harold Koontz and Cyril O’Donnell in Principles of Management as “the managerial function of filling and keeping filled the positions in the organisation structure.” The definition is deliberately narrower than the modern concept of human resource management. Staffing is a line-manager function that has four components:
- Recruitment — identifying and attracting qualified candidates
- Selection — evaluating candidates and choosing the best match
- Placement — assigning the selected candidate to a specific role
- Orientation — integrating the new employee into the organisation
Explanation. The staffing function is frequently confused with the broader field of human resource management. The distinction matters because different functions operate at different levels of the organisation:
- Staffing — a line-manager responsibility to ensure the right people occupy the right positions
- Human resource management — a specialist function that supports staffing through policy, systems, and compliance
- Strategic workforce planning — a senior leadership function that anticipates capability needs and shapes staffing priorities
- Talent development — a joint line-and-HR function that grows capability within the organisation
The interpretive insight is that staffing is not an administrative task delegated to HR. It is a managerial responsibility that no one else can perform on the manager’s behalf. HR can supply the systems and the candidate pipelines; only the line manager can make the decision about which person fits the role.
The Five Core Elements. Staffing must address five questions in a fixed order. Together they form the operational logic of the discipline.
- Why it is done that way — because no strategy can be executed without people capable of executing it; staffing determines the ceiling on what the organisation can achieve
- What is supposed to be done — fill every defined position with a person whose capability, values, and motivation align with the role’s requirements
- When it is done — at role creation; on vacancy; on strategic expansion into new capability areas; continuously for retention and replacement planning
- Who does what — line managers own the staffing decision; HR supplies candidate pipelines, systems, and compliance; senior leadership sets the workforce strategy
- How it is supposed to be done — through structured job analysis, sourcing strategies, validated selection methods, and formal onboarding
Case study. The American technology company Netflix provides a case in point for treating staffing as a line-manager function rather than an HR function. Netflix’s publicly documented culture places hiring decisions entirely with the hiring manager, on the principle that the manager knows the work better than any central function. The company maintains a small HR team and devotes most of its recruitment effort to a single question: does this person raise the average capability of the team they would be joining? The model has produced one of the highest revenue-per-employee figures in the technology sector. By contrast, the Indian state-owned telecom company BSNL provides an illustration of staffing failure. BSNL’s staffing was historically managed centrally with quotas tied to political and regional considerations rather than to operational requirements. By 2020, the company had approximately 65,000 employees generating revenue of about ₹18,000 crore, compared with private competitors operating with far fewer employees and higher revenue. The staffing pattern was not aligned with the operational needs of the business, and no line manager had authority to correct it.
Blog Analysis — Pros and Cons. The evidence from Netflix and BSNL supports the following assessment.
- Pros: When staffing is treated as a line-manager responsibility (Netflix), hiring decisions are made close to the work, and the resulting capability matches what the operation requires. The manager’s judgment about fit is based on real operational knowledge, not abstract role descriptions.
- Cons: When staffing is treated as a central administrative function (BSNL), hiring is driven by considerations that have nothing to do with operational requirements. The result is a workforce that exists on the payroll but cannot execute the business’s strategy. The failure mode is not the absence of staff but the absence of the right staff in the right roles.
Chapter 2 — Recruitment: Sourcing the Candidate Pool
Definition. Recruitment is defined by David Ulrich in Human Resource Champions as “the process of identifying, attracting, and screening potential employees for a specific position or set of positions.” The definition contains three components that distinguish recruitment from selection:
- Identification — determining where qualified candidates exist and how to reach them
- Attraction — presenting the opportunity in a way that motivates qualified candidates to apply
- Screening — filtering the applicant pool to a shortlist for detailed evaluation
Explanation. Recruitment operates through two primary sourcing channels, each with different trade-offs:
- Internal recruitment — promoting or transferring existing employees; faster, lower cost, preserves culture, but can limit fresh perspective and produce inbreeding
- External recruitment — drawing from the labour market outside the organisation; brings new capability, but slower, higher cost, and carries integration risk
The interpretive insight is that recruitment is not a search for the best candidate in the abstract. It is a search for the best candidate who can be sourced within the constraints of the role, the timeline, and the compensation the organisation can offer. Recruitment that ignores those constraints produces a shortlist that no one can hire.
The Five Core Elements.
- Why it is done that way — because the quality of the candidate pool determines the quality of the eventual hire; you cannot select from a pool that does not contain the capability you need
- What is supposed to be done — produce a shortlist of candidates who meet the role’s requirements and are willing to accept the position under its conditions
- When it is done — on role vacancy; proactively ahead of anticipated need; at major expansion or transition points
- Who does what — line managers define requirements and evaluate candidates; HR sources and screens; recruitment specialists target passive candidates; leadership sets overall priorities
- How it is supposed to be done — through clear role specifications, targeted sourcing channels, and a recruitment process that reflects the organisation’s real constraints
Case study. Infosys’s recruitment model provides a case in point for large-scale internal capability development. The company recruits in volume from Indian engineering colleges — over 50,000 graduates per year at peak — and invests in months of standardized training before graduates begin client work. The recruitment channel is narrow (mostly campus-based), the timeline is long, and the investment in training is substantial. What Infosys gains in return is a workforce with a consistent baseline of capability and a strong cultural fit. By contrast, the American software company Oracle has operated one of the most intensive external recruitment systems in the technology industry. Oracle’s acquisitions of PeopleSoft, Siebel, and NetSuite were accompanied by targeted recruitment programs that sought to absorb key engineering and sales talent from the acquired companies. The model gave Oracle immediate access to capability it could not have developed internally on the same timeline, but it also produced integration challenges and cultural friction between legacy Oracle employees and acquired talent.
Blog Analysis — Pros and Cons. The evidence from Infosys and Oracle supports the following assessment.
- Pros: Different recruitment channels produce different capabilities. Infosys’s volume campus model produces a predictable, culturally aligned workforce capable of standardized delivery. Oracle’s acquisition-based recruitment produces immediate access to specialised capability that would take years to develop internally. Both channels are appropriate for their respective strategies.
- Cons: Both channels carry costs. Infosys’s volume model requires long lead times and substantial training investment, and the resulting workforce is less suited to higher-value consulting work. Oracle’s acquisition model produces integration friction and culture clashes. The failure mode is not the channel itself but the assumption that one channel can support every capability need.
Chapter 3 — Selection and Placement: Choosing and Positioning
Definition. Selection is defined by Gary Dessler in Human Resource Management as “the process of choosing the best candidate for a given position from among those who have applied.” Placement is defined by the same source as “the assignment of a selected candidate to a specific job or position.” The distinction matters because selection is a decision and placement is a positioning decision. A firm can select well and still place badly.
Explanation. Selection operates through three categories of assessment tools, each with a different predictive validity for job performance:
- Work sample tests — the highest-validity assessment; the candidate performs a task similar to the actual work
- Structured interviews — moderate validity; standardised questions with consistent scoring rubrics
- Unstructured interviews — low validity; the assessment most commonly used despite being the least predictive
- Personality and cognitive ability tests — moderate to high validity when properly validated for the specific role
The interpretive insight is that selection is a prediction problem. The firm is attempting to predict which candidate will perform well in the role. Any assessment method that does not improve the accuracy of that prediction adds cost without benefit. Unstructured interviews feel informative but are one of the weakest predictors of performance — a finding that has been replicated across decades of research.
The Five Core Elements.
- Why it is done that way — because the cost of a bad hire is substantial; a validated selection process reduces the probability of a costly mistake
- What is supposed to be done — identify the candidate whose capability, values, and motivation predict the highest job performance and retention
- When it is done — after the candidate pool is assembled; before any offer is made; through a series of structured assessments
- Who does what — line managers conduct the primary assessment; HR validates assessment methods; peer interviews contribute context; senior leadership approves the hire in critical roles
- How it is supposed to be done — through validated assessment methods, structured scoring, and multiple independent assessments to reduce bias
Case study. Google’s hiring process, documented by then-SVP of People Operations Laszlo Bock in his 2013 disclosures, provides a case in point for validated selection. Google’s internal research found that unstructured interviews predicted performance at approximately 14%, structured interviews at 26%, and work sample tests at 29%. The company rebuilt its hiring process around the highest-validity methods, added structured scoring rubrics, and introduced peer review panels to reduce interviewer bias. By contrast, a 2017 study of hiring practices in the Indian financial services sector found that most firms continued to rely primarily on unstructured interviews and educational credentials, despite documented low predictive validity. The sector reported high turnover and slow time-to-productivity for new hires. The selection methods did not match the capability the firms needed to build.
Blog Analysis — Pros and Cons. The evidence from Google and the Indian financial services study supports the following assessment.
- Pros: When selection is built on validated assessment methods (Google), the accuracy of the hiring decision improves measurably. Work sample tests and structured interviews reduce the probability of hiring a candidate who looks good in conversation but cannot perform the work.
- Cons: Validated selection methods take time to develop and require expertise to administer. Most organisations continue to rely on methods that feel rigorous but are not (Indian financial services). The failure mode is not the absence of a selection process but the presence of a process that measures the wrong things.
Chapter 4 — Onboarding, Retention, and the Cost of Getting It Wrong
Definition. Onboarding is defined by Talya Bauer in Onboarding New Employees: Maximizing Success as “the process by which new employees acquire the necessary knowledge, skills, and behaviours to become effective organisational members.” The definition shifts the emphasis from the first day of work to the first months, during which the new employee either integrates into the organisation or begins the slow process of disengaging. Retention is defined in the same source as the outcome of successful onboarding — the continued employment of the new hire beyond the period in which they could be easily replaced.
Explanation. The cost of staffing failure is measurable across four categories:
- Recruitment cost — the direct expense of sourcing and selecting the person who left
- Training cost — the investment in capability that is lost when the employee departs
- Productivity gap — the difference between the departing employee’s output and the new hire’s output during the ramp period
- Organisational cost — the effect on team morale, customer relationships, and institutional knowledge
The interpretive insight is that the staffing function is not complete when an offer is accepted. It is complete when the employee has integrated into the organisation and become a productive member. Treating staffing as a hiring decision rather than a multi-month integration process consistently produces avoidable failure.
The Five Core Elements.
- Why it is done that way — because the value of a hire is realised only over time; the first months determine whether the investment pays off or is lost
- What is supposed to be done — integrate the new employee into the role, the team, and the organisation, and build the conditions for continued employment
- When it is done — from the offer acceptance through the first six to twelve months; reviewed at fixed intervals to identify integration problems early
- Who does what — the line manager owns the integration; a buddy or mentor provides peer support; HR supplies the process; senior leadership models the priority
- How it is supposed to be done — through structured onboarding programs, clear expectations, regular feedback, and active management of the first-year experience
Case study. The American software company Salesforce provides a case in point for structured onboarding. Salesforce’s internal data showed that new sales hires who completed a structured four-week onboarding program were 40% more productive in their first quarter than hires who did not. The company invested in onboarding infrastructure including formal learning paths, assigned mentors, and scheduled check-ins at 30, 60, and 90 days. By contrast, the Australian mining company BHP’s experience with fly-in-fly-out operations, cited earlier, provides an illustration of the cost of staffing failure. Two-thirds of new hires in remote operations left within two years, producing an annual cost estimated at hundreds of millions of dollars in recruitment, training, and productivity loss. The company’s post-implementation review identified the absence of effective onboarding and integration as a contributing factor.
Blog Analysis — Pros and Cons. The evidence from Salesforce and BHP supports the following assessment.
- Pros: Structured onboarding (Salesforce) produces measurable increases in early productivity and reduces the probability of premature departure. The investment in onboarding is recovered through faster ramp-up and lower replacement cost.
- Cons: Onboarding is often treated as an administrative process rather than a performance investment (BHP). When it is not structured, the cost of failure compounds across the entire staffing cycle. The failure mode is not the absence of an onboarding program but the absence of one that changes the trajectory of the new employee’s integration.
