I inherited a 500+ page user guide. What I immediately found was repetitive screens.
For example, procedure to Add a XYZ... do this and screen appears, do this and screen appears, do this and screen appears, and so on (4 or 5 pages).
Next procedure to Modify a XYZ -- do this and screen appears (same as in Add a XYZ), do this and screen appears (same as in XYZ), next procedure -- same screens (4 or 5 more pages).
I actually found one "collection" where 16 different procedures includes 90% of the same screens - over and over and over.
My question, how would handle this? Show the screens with only the first procedure and refer user back to the first procedure for all of the other procedures. Or something else??
