Lecture 11. Project Dynamics Flashcards
What are the decompositions of a project?
- of time, leading to sequence of activities.
- of labour, leading to internal specialisms
- in organisational divisions, leading to departmentalisation
- of authority, leading to management levels.
What is the goal of decomposition?
- simultaneous development
- define working clusters of elements
- relate systems parameters to practical organisational aspects
What are partsystems?
- Set of elements
- Set of relations between elements
What is a sub-system?
- Subset of elements of the system. (ie roof construction, foundation bottom slab)
- Component is subsystem but not other way around.
What are aspect-systems?
is a sub set of the relations of a system. (geometrical, structural, architectural etc)
What is a phase system?
a period in which the system has another goal, function or configuration. (moveable bridge, school, storm surge barrier etc)
What is nearly decomposition?
Two step decomposition over different control periods.
What is the short term behaviour of a subsystem determined by?
Internal coherence of the sub system.
What is the long term behaviour of a subsystem determined by?
External coherence between the sub systems.
What is weak coherence?
No many links, or not all possible links.
What is strong coherence?
All links
How are subsystems formed with a matrix?
They are clusters of elements so can be formed using relations.
How can aspect systems be formed with a matrix?
They are clusters of relations so can not be formed using elements.
What is coordination?
Coordination is the control of a system.
What is validation?
Use of models, standards, rules, methods etc.
