Principles need to support a desired quality and be - clearly worded
- consistent
- no further reducible
- plausible
- broadly acknowledged
We mainly address the first three requirements and continuously improve on them. We intend our descriptions and explanations for principles (and practices) to be plausible, but we certainly cannot (and do not intend to) control their broad acknowledgement. For the latter we provide references to further resources, helping readers to make up their own informed opinion. But in the end the borders between values, principles, and practices are based on opinions and experiences and therefore blurry. Readers will come to different conclusions and categorizations. In the end what matters is simply not the answer to the question "Couldn't is been done differently?" (yes, it can!), but "If we do it that other way, wouldn't it have more positive impact on what we do?". The lists of principles and practices are meant as a source of inspiration to be adopted and applied to the reader's own way of working. It is not a dogmatic set of rules. This is by definition a work in progress. If you have a contribution to make, please get in touch! |
