During our development and deployment of our PLM system, we have not been doing such a good job at documenting out best practices and then using those documents for training and demonstration.
We decided as a PLM team to use On-Demand as our training software and documentation for all tracks of the software. Shortly after that decision was made, a manager also made a decision to have additional documentation to be created, which duplicates the information that we have on our On-Demand, for a class training session. Now we have two sources of the same information which can become out of date very easily.
You have to ask the questions, "Was that the right thing to do?" I would say not and so does the rest of the doers that I work with.
One more manager within our team thought he would have a great idea to have each one of us to create a validation plan for our software. The funny thing here is On-Demand creates a validation script for you based on the training material that you have created. Now we have another document that will be duplicating work and not associated with each other.
I hope you learn from our mistakes and do not approach this the same way.
