JESIP Joint Doctrine – the interoperability framework
As well as improving joint working between fire and rescue services and other emergency services, this guidance emphasises the need for all responding organisations to work in a joint and co-ordinated approach. See JESIP Vision - “Working Together – Saving Lives”
Five key principles of joint working
The Joint Doctrine sets out five principles to be applied by responders when they are determining an appropriate course of action in responding to and co-ordinating an emergency. These principles are not hierarchical and can be applied in any order throughout the incident.

The five principles are equally relevant from a major incident perspective and relate to operations at the scene as well as at remote locations. In terms of strategic actions relating to an incident, the strategic co-ordinating group (SCG) or equivalent is likely to be the means by which the principles are applied at a strategic level.
Co-locate – at a strategic coordination centre (SCC) as part of a strategic coordinating group (SCG)
Communicate clearly – with multiple agencies working at the SCC, and representatives from each attending the SCGs it is vital to use plain English and avoid jargon, acronyms or technical language that is not commonly understood
Coordinate across the agencies – one of the first requirements of an SCG will be to agree priorities and objectives using JESIP
Jointly understand risk – at the SCG this is likely to be risk to the wider community, to infrastructure, to the local economy or other significant but strategic risks, rather than just those present at the scene of operations
Shared situational awareness at the SCC using the M/ETHANE message from the scene, the Joint Decision Model and locally agreed multi-agency plans and processes
