New Critical Path Method questions to solve

I've been asked, many times in my workshops for more CPM diagrams to practice.

Here I've compiled few PDM for you to work on.

I'm not solving them right now - want you to work on them and then lets discuss..

Keep busy..

Find out the CPM and total float from below diagrams:

CPM 1:


 CPM2


CPM 3:

Critical Path Method (CPM) Simplified..

A critical path is the longest path in the network.  Each node which falls under critical path has zero or negative float (Slack). Now how do we calculate critical path?? Sample Node I’ve seen various illustrations having different way to calculate CPM, few are: -           The project starts on day 1. -           The project starts on day 0. Both the approaches give same results, however I liked the day 0 approach better, its simpler, easy and lesser room for errors. Example Figure 1 - Example  There are 3 steps to calculate CPM: 1. Forward Pass - To calculate the Early Start(ES) and Early Finish(EF) of node. 2. Backward Pass - To calculate Late Start (LS) and Late Finish(LF) of node. 3. Calculate Float and Thus CPM. The Forward Pass: Forward Pass Illustration We start from first Node or Start node. The works begin on day 0....

Changes in Guide to PMBOK® Ver. 4 to Ver.5

The changes in processes could be categorized as follows: Planning Process Additions: The Planning processes for few of the knowledge areas were clubbed. Now to bring uniformity new planning processes are introduced. These are:         5.1 Plan Scope Management         6.1 Plan Schedule Management         7.1 Plan Cost Management Modification of Process Name for Process Consistency: The process names are changed to bring uniformity across the naming conventions. These are:         4.3 Direct & Manage Project Work (Execution)         5.5 Validate   ( Verify ) Scope          8.1 Plan Quality Management         8.3 Control Quality (Perform Quality Control)         11.6 (Monitor &) Control Risks         12.1 Plan Procurement Management   ...
