Organisations introduce performance appraisal systems, development programmes, competency models and new approaches to motivation. Yet they often fail to ask whether these practices are appropriate for the way the company actually operates.
The same HR practice can support development in one organisation and lead to frustration, empty rituals or the reinforcement of existing problems in another. The quality of the tool alone does not determine the outcome. What matters is the entire system: the nature of the business, the organisation’s stage of development, its dominant approach to decision-making, its understanding of responsibility, and the relationship between people’s needs and business requirements.
In Understanding the System: The HR Function, Katarzyna Klara Radii presents HR as an architecture of conditions for work and organisational development. She demonstrates that the HR function does not operate alongside the system — it is part of it, reflects its logic and helps shape employees’ everyday experience.
The original Spectrum model reveals eight equally valid ways of performing the HR function. They are represented by eight archetypes: Coordinator, Administrator, Pioneer, Guardian, Partner, Strategic Partner, Business Leader and Market Leader. They do not form a maturity ladder. Each responds to different systemic needs, activates different practices and may appear both in its appropriate form and in the shadow created by deficiency or excess.
The author examines the entire employee journey: recruitment, development, motivation, performance appraisal, remuneration, career management and departure from the organisation. She also explores the role of HR in coaching, mentoring, learning and organisational change, as well as the tensions that arise where the interests of the individual and the organisation meet.
Examples from Wells Fargo, Uber, Microsoft, Google and Airbnb illustrate how HR decisions influence people’s behaviour, workplace culture, organisational learning and the costs borne by the system as a whole.
This book is written for HR leaders and teams, managers, consultants, organisational coaches and everyone seeking to design people practices with a deeper awareness of their consequences. It helps shift the focus from “Which solution should we implement?” to a far more important question: “What conditions does this system need today in order to operate and develop appropriately?”.
