Each WBS "level" is an increase in the amount of detail which an activity is sub-divided or grouped (if that makes any sense). A "level" is based on a WBS chart, where any group summary name that resides on the same row is also on the same "level". Each subsequent row of names equates to a new "level". Example:
L1 = CAR
L2 = Mechanical Electrical
L3 = ENGINE,BODY ECU, INSTRUMENTS
L4 = Further subdivisions of each component.
The number of "levels" that you have is wholly dependent upon how how many groupings and sub-groupings you wish to include by the time you reach the individual deliverable. However, you can execute a project and plan a project at any desired level. But the higher the level (3,4,5 ish), the less detail and definition is contained within the activity description. As a rough guide, you are correct in that, down to level 4/5, the activities may be poorly defined. Level 10 is probably excessively detailed.

yes. i also find this classification of L1, L2.. L5 schedule very vague. the most "defined" classifaction i hv come across was this;
L1: (Owners) Development Programme (probably each project/subproj represented by 1 bar)
L2: L1 + Design/Procurement + Construction detail to major discipline
L3: (Contractors) Construction Programme = L2 + Construction detail to floor/area/zone, and trade/system
L4: (Contractors) Monthly Programme = Extract of L3 for 3 months (1 + 2 months Lookahead), detail to weekly work plan for current month.
L5: (Contractors) Weekly Programme = Extract of L4 for the month, detail to daily site work plan for current week.
I find this classification suitably definitive, the only thing i m not sure is... as a contractor preparing L3...
must we incorporate the the monthly details of L4 and weekly details of L5 into the L3?
Any ideas guys?

If you have a look here, for an article by Gary France entitled "Standards for the Levels of a Programme or Schedule" it may help you.
