I suggest flow charts everywhere you can. Especially level 2's. Most larger companies have problems doing some lower level documents in flow charts such as work instructions and/or travelers because their MRP/ERP systems print them.
Almost any procedure can be, and should be, flow charted. Text documents are to be avoided at almost any cost.
At Harley we flow charted just about everything except the 'quality' manual and many assembly and other various documents which the MRP software spits out. My smaller clients do the same.
The problem at many companies is as you get down to the level of assembly / work instructions (in addition to any MRP/ERP systems problems) is the detail level necessary. It becomes harder (with some processes) to use flow charts because of detail issues.
David, you've been visiting the forums long enough to see my extreme Pro-Flow Chart bias. Not to mention my Flow Chart rants.
There are numerous examples in my Implementing ISO Guide (unabashed promo).
At the least, all level 2 'procedures' should be flow charted.
-> I haven't had a client use text level 2's since 1995.
This means I haven't had a client which used text documents as level 2's since 1995. They have all exclusively used flow charts.
-> Do you mean text only L2 procedures?
I'm not sure what you mean here - but if you are saying "Yes - use text only documents for level 2's", the answer is NO. Use Flow Charts for ALL level 2's and the majority of level 3's.
