I don't know how much your workflows vary from project to project which may have some impact on the best way to develop this, but a good starting approach could be to analyze the current workflow(s) that you are using now and then document best practices based on that as well as incorporating research-based best practices into your workflow(s) depending on they type of workflow that needs developed. Checklists, templates, etc. could be developed to assist your staff based on this analysis.

Happy to discuss further. I have developed many processes and project plans for IT related processes in the Healthcare sector. Steve
