Here are some great tips
Planning is the key- plan your year, term, month, week, day
Have clear instructions printed up and laminated for usual tasks for volunteers.
Have tasks lined up for when you get extra helpers- like cleaning or stocktaking.
Never send any extra volunteers away because you have enough people today-there are always extra jobs to do.
Keep records of everything you do, so it can be referred to or used again.
Back everything up [like flyers, instruction cards & newsletters] on disc so you can just alter dates and other info as needed.
An organised workspace means organised workers.
Label all cupboards and shelving so everything gets returned to where it should be.
Delegate where you can.
Encourage people to work while they talk. You can have a conversation just as easily, if you are slicing and dicing or reorganising the utensils drawer whilst you talk.
Some tasks can be done at home by volunteers. Such as washing of tea towels and aprons or homebake or computer work. Advertise for specific jobs rather than we need help next Wednesday.
Minimise the amount of suppliers you use. There is no need to have multiple suppliers. It uses up time, right from ordering through to accepting delivery and account paying.
Minimise walking time by having everything close at hand
If you handwrite something more than once then time is wasting! Have an electronic template that you can alter. Buy a stamp.
