The document introduces the concept of a High Performance Work System (HPWS) which uses human resource practices like self-managing teams, extensive training, and decentralized decision-making to empower employees and improve performance. Basic practices of an HPWS include self-managing teams, open communication, training, flexible work assignments, decentralized decision-making, employment security, and selective hiring. Selective hiring involves having a large applicant pool and carefully considering critical skills needed for each job. Decentralized decision-making delegates authority from top to middle and lower managers to empower employees and make decisions more efficiently. The document distinguishes between work practices focused on work system design and employment practices related to employment relations.
