HR Operations, Roles & Analytics Glossary
HR operations, roles, and analytics is the machinery of the People function itself — the roles that run it, the systems it runs on, and the data it uses to make decisions. This topic gathers those terms, from the CHRO to people analytics, each defined on its own page.
The vocabulary here describes how HR has professionalised. Dedicated roles — the Chief Human Resources Officer, HR business partners, People Operations teams — sit alongside the systems that scale them, such as an HRIS and an applicant tracking system, and the analytics that increasingly drive them. Understanding these terms is understanding how a modern People function is structured, resourced, and held to account.
For GCCs building an HR function from scratch, and for leaders judging whether theirs is fit for purpose, this is the language of the operating model. The terms below give a shared vocabulary for the roles, systems, and measures behind good people management.

Applicant Tracking System ATS An Applicant Tracking System (ATS) is software that manages the recruitment process end to end — collecting applications, storing candidate data, moving people through hiring stages, and coordinating communication between recruiters and hiring managers. It is the central system of record for a company’s hiring activity. Read Change Management Change management is the structured approach to preparing, supporting, and helping people adopt a significant change — such as a new system, structure, or way of working — so that it delivers its intended benefit. It focuses on the human side of change: communication, engagement, training, and addressing resistance. Read Chief Human Resources Officer CHRO A Chief Human Resources Officer (CHRO) is the most senior executive responsible for an organisation’s people strategy, including talent acquisition, compensation, culture, leadership development, and workforce planning. The CHRO typically sits on the executive team and reports to the CEO. Read Hiring Manager A hiring manager is the person who owns an open role and makes the final decision on who to hire — usually the leader the new employee will report to. They define the requirements, assess candidates, and are accountable for the hire’s success, working closely with recruiters who run the search. Read HR Audit An HR audit is a structured review of an organisation’s human-resources policies, processes, and records to check that they are compliant, effective, and aligned with the business. It examines areas such as hiring, contracts, payroll, statutory compliance, and documentation to identify gaps and risks before they become problems. Read HR Business Partner HRBP An HR Business Partner (HRBP) is a senior HR professional embedded with a business unit to align people strategy with business goals. Rather than handling routine HR administration, the HRBP advises leaders on workforce planning, talent, performance, and organisational change. Read HR Compliance HR compliance is the practice of ensuring an organisation’s people policies and employment practices meet all applicable laws and regulations. It covers areas such as hiring, pay, working conditions, statutory benefits, and termination. Read Human Capital Management HCM Human Capital Management (HCM) is the set of practices and technologies used to recruit, manage, develop, and retain an organisation’s workforce as a strategic asset. It spans the full employee lifecycle, from hiring through payroll, performance, and offboarding. Read Human Resource Information System HRIS A Human Resource Information System (HRIS) is the central software an organisation uses to store and manage employee data and core HR processes — records, payroll, benefits, leave, and reporting. It is the single system of record for the workforce. Read Matrix Organisation A matrix organisation is a structure in which employees report along two dimensions at once — commonly a functional line (such as engineering or finance) and a project, product, or regional line. It is designed to balance deep functional expertise with responsiveness to specific projects or markets, at the cost of more complex reporting. Read Objectives and Key Results OKRs Objectives and Key Results (OKRs) is a goal-setting framework in which a team or individual defines a small number of ambitious objectives (what you want to achieve) and, under each, a few measurable key results (how you will know you got there). It is used to align an organisation around shared priorities and to track progress transparently. Read People Analytics People analytics is the practice of collecting and analysing workforce data to inform decisions about hiring, development, engagement, and retention. It applies statistical and analytical methods to HR information — such as attrition, performance, and pay data — to move people decisions from intuition towards evidence. Read People Operations People Operations (People Ops) is a modern reframing of the HR function that treats employees as customers and applies an operational, data-informed mindset to the whole employee experience. It focuses on designing efficient, well-run people processes — from hiring to exit — that help employees do their best work. Read Resume Parsing Resume parsing is the automated extraction of structured information — such as name, contact details, skills, work history, and education — from an unstructured resume or CV so it can be stored, searched, and matched in a recruiting system. It converts a free-form document into database fields. Read Service Level Agreement SLA In recruiting, a service level agreement (SLA) is an agreed set of turnaround and response times between the recruiter and the hiring manager, such as how quickly CVs will be reviewed, interviews scheduled, and feedback given. It keeps a hiring process moving by making each side accountable for its part. Read Span of Control Span of control is the number of direct reports a manager oversees. A wide span means many people report to one manager; a narrow span means few — and the right span shapes how flat or layered an organisation is, how much coordination it needs, and how closely each manager can support their team. Read Talent Management Talent management is the integrated set of practices an organisation uses to attract, develop, deploy, and retain its people across the whole employee lifecycle. It connects recruitment, performance, learning, succession, and reward into one system aimed at building and keeping the capability the business needs. ReadFrequently asked questions

An HRIS (Human Resource Information System) manages data for existing employees — records, payroll, benefits, and time. An ATS (Applicant Tracking System) manages candidates through the hiring process. One runs the workforce; the other runs recruitment.
What is an HR business partner?
An HR business partner is an HR professional embedded with a business unit, aligning people strategy with that unit’s goals. They act as an adviser to leaders rather than a purely administrative or transactional resource.
