The first thing is to think seriously about whether commissioning is right for you, in general. For arts and cultural organisations and individual practitioners being ready for commissioning might mean making some changes to the way you work and will inevitably mean an investment of time and energy. This might be to develop new partnerships or simply to adapt your business plan.
Part of your planning and preparation is about getting organised and everyone has limited time and capacity so efficiency is vital. Being prepared and scheduling ahead reduces the strain and saves time in the long run. You could think about using some online planning and project management tools to help. Being prepared generally (and especially with partnerships) will put you in a more ‘commission ready’ state when the right contract comes up for you and your organisation.
