Hi:
In my experience i have found very usefull to have roadmap, a general plan to show progress toward certification, can collored when finished an activity.
This Roadmap can have:
1. Integrate a steering committee ( top management)
Established date for certify, appoint Management Rep.
2. Process Approach: Define Main Processes in your company ( can use de octopus diagram-automotive industry) this processes are Customer Oriented Processes, then internal processes (support, management etc) and all of them make them visible, in other words, Flow diagram ( can use the turtle /flow again for automotive).
3. Once processes are defined, identify the need or having procedures ( make sure to include those mandatory by the standard) and/ work instructions, formats..
4. Gap Analysis
5. Develop Document structure: Quality Policy ( if not previously defined), Quality Manual, Procedures/WI
6. At the same time there is the need for training: Standard, Audit, Writting documentation, etc
7. Schedule: Management Review, Internal Audits (complete system), visits of certification body....
8. Develop a Plan describing activities.
Attached is one example..it might give you an idea.(it´s in spanish)
