Deciding what you want to achieve will help you work out who should attend. Most awaydays involve ‘the whole team’, as they usually have an aim related to the way the whole team works.
Awaydays will need to be planned far enough in advance for all your invitees to attend, taking account of part-time and flexible working.
If you decide not to include certain members of staff (such as for instance temporary staff) you should be clear about your reasons and make arrangements for them to be brought up to date with the outcomes.
Getting help from your team: you might want team members to run some activities, such as a discussion or a particular problem-solving method. Get them involved early.
Decide how you will record the day’s decisions: you probably do not need full minutes, but you might consider asking one person to be responsible for recording the main outcomes and any actions that have been decided.
Asking people to prepare: you might want to work on something quite complex, in which case it will save a lot of time on the day, and enable a better discussion, if team members do some reading and/or thinking before the day. For example:
“Please could you all read the department’s new strategic plan, and come ready to discuss it.”
or “In preparation for the day, I’d like you to think of (at least) two examples of things that have gone really well in planning for [an activity] and one thing we could have done better.”
