I've taken part in a catastrophic freelancing project full of bad decisions. I left it. As part of the handover, I have to "document my work", which essentially means I have to document the whole project (I am the first who wrote any documents on it).
Now I have to explain how things are going, its structure, architecture, development workflows, etc. It is full of mistakes. Now that I am writing it, I am shocked and also surprised.
The professional behavior would be that I simply write the document without mentioning anything that I think about it. Now the problem is that my name will be in this document, and thus it will seem as if the bad decisions would be at least partially mine.
Of course I could explain, or at least indirectly mention, that "no it wasn't my decision". I could, but it would be obviously highly unprofessional.
I could also write the documents without mentioning anything about any responsibilities. The problem is, that it would in this case shame my name, too. I can also suspect, that my (ex-)coworkers would have a tendency to shame me, instead of acknowledging their mistakes. But I obviously can't shame also their name.
How to solve this contradiction? Or, in a more broad sense: what is the optimal, professional way in such a situation?
