Ch6.3 - Sequence Activities Flashcards
What is the Sequence Activities process
process of identifying and documenting relationships among the project activities
What is the key benefit of the Sequence Activities process?
defines the logical sequence of work to obtain the greatest efficiency given all project constraints.
Inputs for Sequence Activities process (7)
EEF, OPA, Schedule Mgmt Plan, activity List, Activity Attributes, Milestone List, Project Scope statement
ITTO Diagram
Insert Diagram 6.3
TT for Sequence Activities process (3)
Precedence Diagraming, dependency determination, leads/lags
Outputs for Sequence Activities process (2)
Project schedule network diagrams, project doc update
Input: Schedule Management Plan
Needed so that we know the scheduling method and tool to be used for the project
Input: Activity List
Needed all activities so that they can be sequenced
Input: Activity Attributes
attributes may describe a necessary sequence of events or defined predecessor or successor relationships.
Input: Milestone List
milestone list may have scheduled dates for specific milestones, which may influence the way activities are sequenced.
Input: Project Scope Statement
contains the product scope description, which includes product characteristics that may affect activity sequencing, such as the physical layout of a plant to be constructed or subsystem interfaces on a software project. project deliverables, project constraints, and project assumptions may also affect activity sequencing.
Input: EEF
Govt/industry standards, PMIS, scheduling tools
Input: OPA
Lessons learned, standardized process, templates
TT: PDM
Precedence diagramming method (PDM), Dependency determination, leads and lags
TT: Dependency Determination (4 attributes)
mandatory, discretionary, internal, external
TT: Leads and Lags
Lead - amount of time whereby a successor activity can be advanced with respect to a predecessor activity. often represented as a negative value for lag
Output: Project Documents Updates
Activity lists,
Activity attributes,
Milestone list, and
Risk register.
Output: Project Schedule Network Diagrams
graphical representation of the logical relationships, also referred to as dependencies, among the project schedule activities. full project details, or have one or more summary activities
PDM - method of representing a precedence diagram is known as what?
AON - Activity on Node
PDM - 2 types of activities
predecessor, successor
PDM - 4 types of relationships
FS, FF, SS, SF
PDM - dependency attributes interact in 4 ways
mandatory external dependencies, mandatory internal dependencies, discretionary external dependencies, or discretionary internal dependencies.
Mandatory dependencies
legally or contractually required or inherent in the nature of the work, aka hard logic or hard dependencies
Discretionary dependencies
best practices, desired sequence even though there are other acceptable sequences, preferred logic, preferential logic, or soft logic. Should be fully documented since create arbitrary float values
External dependencies
relationship between project activities and non-project activities, usually outside the project team’s control. Ie software delivery
Internal dependencies
precedence relationship between project activities and are generally inside the project team’s control. Ex: if the team cannot test a machine until they assemble it, this is an internal mandatory dependency
