Objective of the diagram is to pass along information on the projectchoice of diagram type should be driven by this fact? Milestones can be shown on PDM as activities with zero duration? ADM you must identify all activities and all milestones, PDM allows you to choose what milestones you want? ADM – you can add ‘dummy’ activities (lines with no duration) to force dependency?

Procedures? A Process is a high level concept that can be applied across anizations, across industry. It tries to minimize ambiguity but must allow flexibility for different cultures?For example ‘identify risks that can impact delivery’? A Procedure is the detailed steps to adhere to the process. The procedure is specific to an anization.? example ‘plete the attached risk identification spreadsheet by holding a two meeting with all team leaders of each functional area. There should be at least 20 risks identified and quantified’. The pleted spreadsheet must be stored on the project server.’44BrenDaniel Productions CorpYour Team’s BaseDo you follow a documented procedureDo all the PMs follow a documented procedure/processDo your senior manage
