11、nnel A chart called project organization structure is often used to illustrate project participants and their inter-relationship within a project system,Project Owner,Construction Project Participants,Project As a System,System definition Any group of entities which are functionally interdependent c

12、an be called a system Any group of entities which are interrelated so as to perform some function, or reach some goal, can be seen to be acting as a system Focus of system theory Sub-system Interrelated in the pursuit of goals or objectives Primary task of the system The things the organization must

13、 to do to survive,Project As a System,Important Concepts Large system comprise smaller sub-systems which share the goals or primary task of larger system Sub-systems are independently work together towards the common goal Sub-systems form a hierarchy of systems System interacts with its environment,

14、 and affected by environmental constraints or influences The environment is not part of the system it does not share the goals of the system,Project As a System,Important Concepts The system receives inputs from and exports outputs to the environment through sort of internal conversion process A per

15、meable boundary exists between the system and its environment “Boundary Management” is a key system concept Part of the outputs is fed back to become an input and thus to establish a cycle of events which enable the system to monitor it own behavior,Construction System Model,Construction Production

20、ried out to accomplish the project Can be used as tool for work breakdown,Work Breakdown Structure,A complex project is made easy to deal with by first breaking it down into individual activities in a hierarchical structure, known as WBS It defines tasks that can be completed independently of other

21、tasks, facilitating Resource allocation Assignment of responsibilities Measurement and control of the project,Work Breakdown Structure,Higher levels in the hierarchical structure are generally performed by groups The lowest level in the structure often comprises activities performed by individuals I

22、t is the key to Scope management Team assignment Accurate tracking Effective control,Work Breakdown Structure,Work breakdown structure can be done like this: The project manager lists everything should be done in the project Then the stakeholders put up their “to do” list with requirements Then the

23、project will have unneeded tasks, and scope will continually expand Then the project will run over time, over budget, and even with dissatisfied quality,x,Work Breakdown Structure,Work breakdown structure can be done like this: First break down into components Then break down into process Then The l
