Local people have a great amount of experience and insight into what works for them, what does not work for them, and why. So they contribute to the success of any health intervention. Involving local people in planning can increase their commitment to the programme and it can help them to develop appropriate skills and knowledge to identify and solve their problems on their own. Involving local people helps to increase the resources available for the programme, promotes self-help and self-reliance, and improves trust and partnership between the community and health workers. It is also a way to bring about 'social learning' for both health workers and local people. Therefore, if you involve the local community in a programme which is developed for them, you will find they will gain from these benefits.
