Book excerpt: In the new world of work, agility is a business imperative. Agile HR is a practical guide written specifically for people professionals on how the HR function can develop agile processes and practices that save time, boost performance and support overall business goals. From small tech start-ups or large traditional companies, organizations need to be fast, flexible and digitally empowered to succeed. However, too many companies are stuck with siloed, compliance-driven HR processes that work in opposition to the business rather than supporting it. This results in the view that HR is slow and out of touch. However, Agile HR shows that this doesn't need to be the case. Covering every aspect of the HR function from people processes, ways of working and HR services to organization design, operating models and HR teams, Agile HR is an essential guide for all HR practitioners wanting to make their HR practices agile and drive business performance but don't know where to start. As well as guidance on how to deal with resistance, manage a backlog and deal with constraints, there is also invaluable guidance on how HR can prioritize effectively and assess which activities to pursue, which to develop, which to rework and which to abandon in order to achieve continuous business improvement. Supported by case studies from organizations who have seen the benefits of an agile approach to HR including Sky Betting & Gaming and MUJI, this is critical reading for all HR professionals in organizations of any size needing to adopt fast, flexible and evolving agile approaches to effectively compete in the new world of work.
