D follows A while E follows C 3. B, D and E restricts the start of J 4. K and F cannot start until B, D and E are completed 5. G follows C and precedes H and I 6. H and I cannot proceed until F is completed 7. L follows K and precedes N 8. J restricts the start of P, M and S 9. H, I and P must be completed before Q can start 10. L and M must be completed before N can start 11. O follows N while R follows Q. 12. R, O and S culminates at the same time
