pbl 1 meeting 1

for the first time reading this problem,i found out that there are problems in determining the available stock asap in the sales department.but i still do not know how they will solve this problem through SDLC. this PBL session taught me how to find main problem in a given situation and find the alternatives to solve it.but there are things that i don't like,i mean don't really like about this PBL is i need to understand everything on my own first before meeting for every session.
