1. Activity Definition Activity List Resource Plan Activity sequencing Activity Resource Estimating Activity Duration Estimating Duration Estimate Network Diagram Schedule Development Integrated Schedule

2. Activity Sequencing Activities are “sequenced” by creating a network that defines the relationships between the various activities Method: Define relationships Select network format Map activity list into network

3. Sequencing Relationships Relationships between tasks are defined by either: Resource constraints = sharing common resources – dealt with in “resource estimating” section later Logical constraints = logical connection between the activities, eg. Can’t review the report until it is written, can’t approve it until it is reviewed, etc.

4. Example Logical Relationships We need complete the work, inspect and ship it. (Finish-to-start) The shipping paperwork does not depend on the work being done, but we don’t want to delay shipment for it, so we want it done once the inspection is complete. (Finish-to-Finish) We want to warn our customs broker once we have drawn the shipper number, which is the first thing in preparing the paperwork (Start-to-Start)

5. Determining Dependencies Within work packages: Work package “associated” with one organizational function the functional lead or team member will usually understand and specify relationships Between work packages: These connections often lost This is where WBS Dictionary “discipline” is valuable – forces team members to think about the inputs to, and outputs from their Work Packages

8. Networking Techniques Shipping Paperwork Complete Work Inspect Work Ship Call Customs GANTT Chart with precedence arrows Commonly used Not a network diagram Clear presentation of SS and FF relationships Difficult to see relationships to tasks other than those nearby Precedence Diagram Method (PDM) (Activity-on-Node, AON) Convenient presentation of FS relationships for large networks Easy to summarize activity details in “nodes” FF/SS relationships difficult Arrow Diagram Method (ADM) (Activity-on-Arrow, AOA) Rarely used Only FS relationships May require “dummy tasks” to fully define

9. Viewing the network Most scheduling applications will have a “PERT” or “Network” view Switch to this: Move the “nodes” into an “aesthetically” pleasing network “reality check” the completeness of you dependencies
