This is a toolkit on how to invent, adopt or adapt ideas that can deliver better results. It’s quick to use, simple to apply, and designed to help busy people working in development. It draws on a study of many hundreds of tools currently being used – here we have included only the ones which practitioners found most useful. The tools are not coming out of thin air. many of them are well documented and have been widely used in other sectors. In that sense this toolkit is standing on the shoulders of giants, and we are happy to acknowledge that.
