9 Trail and experiment
In the main, there is rarely the perfect way of doing anything. Progress is generally achieved through evolutionary incremental improvements. So taking a trial and error approach to continuous improvement encourages people to take reasonable risks and to innovate. It also means that people do not have to get so attached to ‘their way’ that they cannot consider any other way.
It is suggested that ideas be rapidly trialed so that learning is quick and ideas that don’t work can quickly be ‘sacked’.
You should aim to base your trials on good evidence. Research and investigate better ways of doing things and then test it in your context.
This is how you produce good evidence for the things that you do.
