11.1 Definition and measurement
Churn is defined as: the relocation of people within an agency, undertaken in response to changing service-delivery and functional requirements.
Churn is measured by: the number of people relocated per year, expressed as a percentage an agency's total number of full-time equivalent (FTE) staff.
11.2 Churn drivers
The drivers for churn can be broadly categorised as follows:
- organisational restructuring as a consequence of changes in ministerial portfolios and changed service delivery
- new styles of management such as incorporating flatter structures and cross-functional teams
- the demands of new technology
- the need for increased workplace efficiency and effectiveness
- changes to work patterns (e.g. distributed working, part-time working, flexible desking)
- the expectations of workers and the community.
11.3 Types of churn
Types of churn, ranked in order from least to most complexity, time, cost, and disruption, are:
- virtual churn, involving redesignation of tasks and reporting responsibilities, reassignment of electronic data access and electronic address but no physical relocation
- relocation of people within the existing number and location of workstations, sometimes referred to as a 'box and briefcase' move
- relocation of people, furniture and technology, and possibly requiring some workstation replanning
- relocation of people, furniture, and technology, and also involving changes to built fitout and/or building services
- moving from one location to another involving the construction of a completely new fitout, including modifications to building systems as required.
11.4 Dealing with churn
The key success factors for effective churn management are:
- accurate and timely forecasting of office-space demand through strategic planning
- fitout designed in accordance with best-practice principles.
Effective approaches to managing churn include:
- considering alternative workplace practices
- adapting existing space to new uses to minimise physical changes
- exploiting technological solutions to churn management such as virtual relocations, wireless technology and networks (for maximised spatial mobility), convergent technology and teleconferencing
- designing workplace layouts and fitout generically for maximum flexibility and interchangeability
- constructing a centralised core or zone of multi-purpose, shared support spaces for the longerterm in preference to specialised spaces that become functionally obsolete in the short term
- maximising the use of mobile and/or transformable (multi-purpose) furniture
- identifying and 'capturing' inefficient space and then redistributing it for better workplace efficiency and savings in total space needs (and rent).
The opportunities for best-practice churn management arise in the earliest stages of strategic planning and design. Additional information and advice is available from the Department of Housing and Public Works.
