1.How long will it take to complete the project

2) Which activities must be completed on time to avoid delays in project duratation

3) What is the slack of ech of the path ?

Solution

Q1) Critical path is ABEIKL --> Longest duration = 2+8+7+3+6+1 = 27 days

Q2) The activities on critical path viz. A,B,E,I,K,L must be completed on time to avoid delays in project duration.

Q3) Path - ABH = 20 days ----> Slack = Critical path - Path of ABH = 27-20 = 7 days

Path - ACFIKL = 21 days -----> Slack = Critical path - Path of ACFIKL = 27-21 = 6 days

Path - ADGIKL = 26 days -----> Slack = Critical path - Path of ADGIKL = 27-26 = 1 day

Path - ADJ = 22 days -----> Slack = Critical path - Path of ADJ = 27-22 = 5 days
